# shadcn/ui
A framework for building ui, components and design systems. Components are added as source code to the user's project via the CLI.
> **IMPORTANT:** Run all CLI commands using the project's package runner: `npx shadcn@latest`, `pnpm dlx shadcn@latest`, or `bunx --bun shadcn@latest` — based on the project's `packageManager`. Examples below use `npx shadcn@latest` but substitute the correct runner for the project.
## When to Use
- Use when adding new components from shadcn/ui or community registries.
- Use when styling, composing, or debugging existing shadcn/ui components.
- Use when initializing a new project or switching design system presets.
- Use to retrieve component documentation, examples, and API references.
## Current Project Context
```json
!`npx shadcn@latest info --json 2>/dev/null || echo '{"error": "No shadcn project found. Run shadcn init first."}'`
```
The JSON above contains the project config and installed components. Use `npx shadcn@latest docs <component>` to get documentation and example URLs for any component.
## Principles
1. **Use existing components first.** Use `npx shadcn@latest search` to check registries before writing custom UI. Check community registries too.
2. **Compose, don't reinvent.** Settings page = Tabs + Card + form controls. Dashboard = Sidebar + Card + Chart + Table.
3. **Use built-in variants before custom styles.** `variant="outline"`, `size="sm"`, etc.
4. **Use semantic colors.** `bg-primary`, `text-muted-foreground` — never raw values like `bg-blue-500`.
## Critical Rules
These rules are **always enforced**. Each links to a file with Incorrect/Correct code pairs.
### Styling & Tailwind → [styling.md](./rules/styling.md)
- **`className` for layout, not styling.** Never override component colors or typography.
- **No `space-x-*` or `space-y-*`.** Use `flex` with `gap-*`. For vertical stacks, `flex flex-col gap-*`.
- **Use `size-*` when width and height are equal.** `size-10` not `w-10 h-10`.
- **Use `truncate` shorthand.** Not `overflow-hidden text-ellipsis whitespace-nowrap`.
- **No manual `dark:` color overrides.** Use semantic tokens (`bg-background`, `text-muted-foreground`).
- **Use `cn()` for conditional classes.** Don't write manual template literal ternaries.
- **No manual `z-index` on overlay components.** Dialog, Sheet, Popover, etc. handle their own stacking.
### Forms & Inputs → [forms.md](./rules/forms.md)
- **Forms use `FieldGroup` + `Field`.** Never use raw `div` with `space-y-*` or `grid gap-*` for form layout.
- **`InputGroup` uses `InputGroupInput`/`InputGroupTextarea`.** Never raw `Input`/`Textarea` inside `InputGroup`.
- **Buttons inside inputs use `InputGroup` + `InputGroupAddon`.**
- **Option sets (2–7 choices) use `ToggleGroup`.** Don't loop `Button` with manual active state.
- **`FieldSet` + `FieldLegend` for grouping related checkboxes/radios.** Don't use a `div` with a heading.
- **Field validation uses `data-invalid` + `aria-invalid`.** `data-invalid` on `Field`, `aria-invalid` on the control. For disabled: `data-disabled` on `Field`, `disabled` on the control.
### Component Structure → [composition.md](./rules/composition.md)
- **Items always inside their Group.** `SelectItem` → `SelectGroup`. `DropdownMenuItem` → `DropdownMenuGroup`. `CommandItem` → `CommandGroup`.
- **Use `asChild` (radix) or `render` (base) for custom triggers.** Check `base` field from `npx shadcn@latest info`. → [base-vs-radix.md](./rules/base-vs-radix.md)
- **Dialog, Sheet, and Drawer always need a Title.** `DialogTitle`, `SheetTitle`, `DrawerTitle` required for accessibility. Use `className="sr-only"` if visually hidden.
- **Use full Card composition.** `CardHeader`/`CardTitle`/`CardDescription`/`CardContent`/`CardFooter`. Don't dump everything in `CardContent`.
- **Button has no `isPending`/`isLoading`.** Compose with `Spinner` + `data-icon` + `disabled`.
- **`TabsTrigger` must be inside `TabsList`.** Never render triggers directly in `Tabs`.
- **`Avatar` always needs `AvatarFallback`.** For when the image fails to load.
### Use Components, Not Custom Markup → [composition.md](./rules/composition.md)
- **Use existing components before custom markup.** Check if a component exists before writing a styled `div`.
- **Callouts use `Alert`.** Don't build custom styled divs.
- **Empty states use `Empty`.** Don't build custom empty state markup.
- **Toast via `sonner`.** Use `toast()` from `sonner`.
- **Use `Separator`** instead of `<hr>` or `<div className="border-t">`.
- **Use `Skeleton`** for loading placeholders. No custom `animate-pulse` divs.
- **Use `Badge`** instead of custom styled spans.
### Icons → [icons.md](./rules/icons.md)
- **Icons in `Button` use `data-icon`.** `data-icon="inline-start"` or `data-icon="inline-end"` on the icon.
- **No sizing classes on icons inside components.** Components handle icon sizing via CSS. No `size-4` or `w-4 h-4`.
- **Pass icons as objects, not string keys.** `icon={CheckIcon}`, not a string lookup.
### CLI
- **Never decode or fetch preset codes manually.** Pass them directly to `npx shadcn@latest init --preset <code>`.
## Key Patterns
These are the most common patterns that differentiate correct shadcn/ui code. For edge cases, see the linked rule files above.
```tsx
// Form layout: FieldGroup + Field, not div + Label.
<FieldGroup>
<Field>
<FieldLabel htmlFor="email">Email</FieldLabel>
<Input id="email" />
</Field>
</FieldGroup>
// Validation: data-invalid on Field, aria-invalid on the control.
<Field data-invalid>
<FieldLabel>Email</FieldLabel>
<Input aria-invalid />
<FieldDescription>Invalid email.</FieldDescription>
</Field>
// Icons in buttons: data-icon, no sizing classes.
<Button>
<SearchIcon data-icon="inline-start" />
Search
</Button>
// Spacing: gap-*, not space-y-*.
<div className="flex flex-col gap-4"> // correct
<div className="space-y-4"> // wrong
// Equal dimensions: size-*, not w-* h-*.
<Avatar className="size-10"> // correct
<Avatar className="w-10 h-10"> // wrong
// Status colors: Badge variants or semantic tokens, not raw colors.
<Badge variant="secondary">+20.1%</Badge> // correct
<span className="text-emerald-600">+20.1%</span> // wrong
```
## Component Selection
| Need | Use |
| -------------------------- | --------------------------------------------------------------------------------------------------- |
| Button/action | `Button` with appropriate variant |
| Form inputs | `Input`, `Select`, `Combobox`, `Switch`, `Checkbox`, `RadioGroup`, `Textarea`, `InputOTP`, `Slider` |
| Toggle between 2–5 options | `ToggleGroup` + `ToggleGroupItem` |
| Data display | `Table`, `Card`, `Badge`, `Avatar` |
| Navigation | `Sidebar`, `NavigationMenu`, `Breadcrumb`, `Tabs`, `Pagination` |
| Overlays | `Dialog` (modal), `Sheet` (side panel), `Drawer` (bottom sheet), `AlertDialog` (confirmation) |
| Feedback | `sonner` (toast), `Alert`, `Progress`, `Skeleton`, `Spinner` |
| Command palette | `Command` inside `Dialog` |
| Charts | `Chart` (wraps Recharts) |
| Layout | `Card`, `Separator`, `Resizable`, `ScrollArea`, `Accordion`, `Collapsible` |
| Empty states | `Empty` |
| Menus | `DropdownMenu`, `ContextMenu`, `Menubar` |
| Tooltips/info | `Tooltip`, `HoverCard`, `Popover` |
## Key Fields
The injected project context contains these key fields:
- **`aliases`** → use the actual alias prefix for imports (e.g. `@/`, `~/`), never hardcode.
- **`isRSC`** → when `true`, components using `useState`, `useEffect`, event handlers, or browser APIs need `"use client"` at the top of the file. Always reference this field when advising on the directive.
- **`tailwindVersion`** → `"v4"` uses `@theme inline` blocks; `"v3"` uses `tailwind.config.js`.
- **`tailwindCssFile`** → the global CSS file where custom CSS variables are defined. Always edit this file, never create a new one.
- **`style`** → component visual treatment (e.g. `nova`, `vega`).
- **`base`** → primitive library (`radix` or `base`). Affects component APIs and available props.
- **`iconLibrary`** → determines icon imports. Use `lucide-react` for `lucide`, `@tabler/icons-react` for `tabler`, etc. Never assume `lucide-react`.
- **`resolvedPaths`** → exact file-system destinations for components, utils, hooks, etc.
- **`framework`** → routing and file conventions (e.g. Next.js App Router vs Vite SPA).
- **`packageManager`** → use this for any non-shadcn dependency installs (e.g. `pnpm add date-fns` vs `npm install date-fns`).
See [cli.md — `info` command](./cli.md) for the full field reference.
## Component Docs, Examples, and Usage
Run `npx shadcn@latest docs <component>` to get the URLs for a component's documentation, examples, and API reference. Fetch these URLs to get the actual content.
```bash
npx shadcn@latest docs button dialog select
```
**When creating, fixing, debugging, or using a component, always run `npx shadcn@latest docs` and fetch the URLs first.** This ensures you're working with the correct API and usage patterns rather than guessing.
## Workflow
1. **Get project context** — already injected above. Run `npx shadcn@latest info` again if you need to refresh.
2. **Check installed components first** — before running `add`, always check the `components` list from project context or list the `resolvedPaths.ui` directory. Don't import components that haven't been added, and don't re-add ones already installed.
3. **Find components** — `npx shadcn@latest search`.
4. **Get docs and examples** — run `npx shadcn@latest docs <component>` to get URLs, then fetch them. Use `npx shadcn@latest view` to browse registry items you haven't installed. To preview changes to installed components, use `npx shadcn@latest add --diff`.
5. **Install or update** — `npx shadcn@latest add`. When updating existing components, use `--dry-run` and `--diff` to preview changes first (see [Updating Components](#updating-components) below).
6. **Fix imports in third-party components** — After adding components from community registries (e.g. `@bundui`, `@magicui`), check the added non-UI files for hardcoded import paths like `@/components/ui/...`. These won't match the project's actual aliases. Use `npx shadcn@latest info` to get the correct `ui` alias (e.g. `@workspace/ui/components`) and rewrite the imports accordingly. The CLI rewrites imports for its own UI files, but third-party registry components may use default paths that don't match the project.
7. **Review added components** — After adding a component or block from any registry, **always read the added files and verify they are correct**. Check for missing sub-components (e.g. `SelectItem` without `SelectGroup`), missing imports, incorrect composition, or violations of the [Critical Rules](#critical-rules). Also replace any icon imports with the project's `iconLibrary` from the project context (e.g. if the registry item uses `lucide-react` but the project uses `hugeicons`, swap the imports and icon names accordingly). Fix all issues before moving on.
8. **Registry must be explicit** — When the user asks to add a block or component, **do not guess the registry**. If no registry is specified (e.g. user says "add a login block" without specifying `@shadcn`, `@tailark`, etc.), ask which registry to use. Never default to a registry on behalf of the user.
9. **Switching presets** — Ask the user first: **reinstall**, **merge**, or **skip**?
- **Reinstall**: `npx shadcn@latest init --preset <code> --force --reinstall`. Overwrites all components.
- **Merge**: `npx shadcn@latest init --preset <code> --force --no-reinstall`, then run `npx shadcn@latest info` to list installed components, then for each installed component use `--dry-run` and `--diff` to [smart merge](#updating-components) it individually.
- **Skip**: `npx shadcn@latest init --preset <code> --force --no-reinstall`. Only updates config and CSS, leaves components as-is.
## Updating Components
When the user asks to update a component from upstream while keeping their local changes, use `--dry-run` and `--diff` to intelligently merge. **NEVER fetch raw files from GitHub manually — always use the CLI.**
1. Run `npx shadcn@latest add <component> --dry-run` to see all files that would be affected.
2. For each file, run `npx shadcn@latest add <component> --diff <file>` to see what changed upstream vs local.
3. Decide per file based on the diff:
- No local changes → safe to overwrite.
- Has local changes → read the local file, analyze the diff, and apply upstream updates while preserving local modifications.
- User says "just update everything" → use `--overwrite`, but confirm first.
4. **Never use `--overwrite` without the user's explicit approval.**
## Quick Reference
```bash
# Create a new project.
npx shadcn@latest init --name my-app --preset base-nova
npx shadcn@latest init --name my-app --preset a2r6bw --template vite
# Create a monorepo project.
npx shadcn@latest init --name my-app --preset base-nova --monorepo
npx shadcn@latest init --name my-app --preset base-nova --template next --monorepo
# Initialize existing project.
npx shadcn@latest init --preset base-nova
npx shadcn@latest init --defaults # shortcut: --template=next --preset=base-nova
# Add components.
npx shadcn@latest add button card dialog
npx shadcn@latest add @magicui/shimmer-button
npx shadcn@latest add --all
# Preview changes before adding/updating.
npx shadcn@latest add button --dry-run
npx shadcn@latest add button --diff button.tsx
npx shadcn@latest add @acme/form --view button.tsx
# Search registries.
npx shadcn@latest search @shadcn -q "sidebar"
npx shadcn@latest search @tailark -q "stats"
# Get component docs and example URLs.
npx shadcn@latest docs button dialog select
# View registry item details (for items not yet installed).
npx shadcn@latest view @shadcn/button
```
**Named presets:** `base-nova`, `radix-nova`
**Templates:** `next`, `vite`, `start`, `react-router`, `astro` (all support `--monorepo`) and `laravel` (not supported for monorepo)
**Preset codes:** Base62 strings starting with `a` (e.g. `a2r6bw`), from [ui.shadcn.com](https://ui.shadcn.com).

# shadcn CLI Reference
Configuration is read from `components.json`.
> **IMPORTANT:** Always run commands using the project's package runner: `npx shadcn@latest`, `pnpm dlx shadcn@latest`, or `bunx --bun shadcn@latest`. Check `packageManager` from project context to choose the right one. Examples below use `npx shadcn@latest` but substitute the correct runner for the project.
> **IMPORTANT:** Only use the flags documented below. Do not invent or guess flags — if a flag isn't listed here, it doesn't exist. The CLI auto-detects the package manager from the project's lockfile; there is no `--package-manager` flag.
## Contents
- Commands: init, add (dry-run, smart merge), search, view, docs, info, build
- Templates: next, vite, start, react-router, astro
- Presets: named, code, URL formats and fields
- Switching presets
---
## Commands
### `init` — Initialize or create a project
```bash
npx shadcn@latest init [components...] [options]
```
Initializes shadcn/ui in an existing project or creates a new project (when `--name` is provided). Optionally installs components in the same step.
| Flag | Short | Description | Default |
| ----------------------- | ----- | --------------------------------------------------------- | ------- |
| `--template <template>` | `-t` | Template (next, start, vite, next-monorepo, react-router) | — |
| `--preset [name]` | `-p` | Preset configuration (named, code, or URL) | — |
| `--yes` | `-y` | Skip confirmation prompt | `true` |
| `--defaults` | `-d` | Use defaults (`--template=next --preset=base-nova`) | `false` |
| `--force` | `-f` | Force overwrite existing configuration | `false` |
| `--cwd <cwd>` | `-c` | Working directory | current |
| `--name <name>` | `-n` | Name for new project | — |
| `--silent` | `-s` | Mute output | `false` |
| `--rtl` | | Enable RTL support | — |
| `--reinstall` | | Re-install existing UI components | `false` |
| `--monorepo` | | Scaffold a monorepo project | — |
| `--no-monorepo` | | Skip the monorepo prompt | — |
`npx shadcn@latest create` is an alias for `npx shadcn@latest init`.
### `add` — Add components
> **IMPORTANT:** To compare local components against upstream or to preview changes, ALWAYS use `npx shadcn@latest add <component> --dry-run`, `--diff`, or `--view`. NEVER fetch raw files from GitHub or other sources manually. The CLI handles registry resolution, file paths, and CSS diffing automatically.
```bash
npx shadcn@latest add [components...] [options]
```
Accepts component names, registry-prefixed names (`@magicui/shimmer-button`), URLs, or local paths.
| Flag | Short | Description | Default |
| --------------- | ----- | -------------------------------------------------------------------------------------------------------------------- | ------- |
| `--yes` | `-y` | Skip confirmation prompt | `false` |
| `--overwrite` | `-o` | Overwrite existing files | `false` |
| `--cwd <cwd>` | `-c` | Working directory | current |
| `--all` | `-a` | Add all available components | `false` |
| `--path <path>` | `-p` | Target path for the component | — |
| `--silent` | `-s` | Mute output | `false` |
| `--dry-run` | | Preview all changes without writing files | `false` |
| `--diff [path]` | | Show diffs. Without a path, shows the first 5 files. With a path, shows that file only (implies `--dry-run`) | — |
| `--view [path]` | | Show file contents. Without a path, shows the first 5 files. With a path, shows that file only (implies `--dry-run`) | — |
#### Dry-Run Mode
Use `--dry-run` to preview what `add` would do without writing any files. `--diff` and `--view` both imply `--dry-run`.
```bash
# Preview all changes.
npx shadcn@latest add button --dry-run
# Show diffs for all files (top 5).
npx shadcn@latest add button --diff
# Show the diff for a specific file.
npx shadcn@latest add button --diff button.tsx
# Show contents for all files (top 5).
npx shadcn@latest add button --view
# Show the full content of a specific file.
npx shadcn@latest add button --view button.tsx
# Works with URLs too.
npx shadcn@latest add https://api.npoint.io/abc123 --dry-run
# CSS diffs.
npx shadcn@latest add button --diff globals.css
```
**When to use dry-run:**
- When the user asks "what files will this add?" or "what will this change?" — use `--dry-run`.
- Before overwriting existing components — use `--diff` to preview the changes first.
- When the user wants to inspect component source code without installing — use `--view`.
- When checking what CSS changes would be made to `globals.css` — use `--diff globals.css`.
- When the user asks to review or audit third-party registry code before installing — use `--view` to inspect the source.
> **`npx shadcn@latest add --dry-run` vs `npx shadcn@latest view`:** Prefer `npx shadcn@latest add --dry-run/--diff/--view` over `npx shadcn@latest view` when the user wants to preview changes to their project. `npx shadcn@latest view` only shows raw registry metadata. `npx shadcn@latest add --dry-run` shows exactly what would happen in the user's project: resolved file paths, diffs against existing files, and CSS updates. Use `npx shadcn@latest view` only when the user wants to browse registry info without a project context.
#### Smart Merge from Upstream
See [Updating Components in SKILL.md](./SKILL.md#updating-components) for the full workflow.
### `search` — Search registries
```bash
npx shadcn@latest search <registries...> [options]
```
Fuzzy search across registries. Also aliased as `npx shadcn@latest list`. Without `-q`, lists all items.
| Flag | Short | Description | Default |
| ------------------- | ----- | ---------------------- | ------- |
| `--query <query>` | `-q` | Search query | — |
| `--limit <number>` | `-l` | Max items per registry | `100` |
| `--offset <number>` | `-o` | Items to skip | `0` |
| `--cwd <cwd>` | `-c` | Working directory | current |
### `view` — View item details
```bash
npx shadcn@latest view <items...> [options]
```
Displays item info including file contents. Example: `npx shadcn@latest view @shadcn/button`.
### `docs` — Get component documentation URLs
```bash
npx shadcn@latest docs <components...> [options]
```
Outputs resolved URLs for component documentation, examples, and API references. Accepts one or more component names. Fetch the URLs to get the actual content.
Example output for `npx shadcn@latest docs input button`:
```
base radix
input
docs https://ui.shadcn.com/docs/components/radix/input
examples https://raw.githubusercontent.com/.../examples/input-example.tsx
button
docs https://ui.shadcn.com/docs/components/radix/button
examples https://raw.githubusercontent.com/.../examples/button-example.tsx
```
Some components include an `api` link to the underlying library (e.g. `cmdk` for the command component).
### `diff` — Check for updates
Do not use this command. Use `npx shadcn@latest add --diff` instead.
### `info` — Project information
```bash
npx shadcn@latest info [options]
```
Displays project info and `components.json` configuration. Run this first to discover the project's framework, aliases, Tailwind version, and resolved paths.
| Flag | Short | Description | Default |
| ------------- | ----- | ----------------- | ------- |
| `--cwd <cwd>` | `-c` | Working directory | current |
**Project Info fields:**
| Field | Type | Meaning |
| -------------------- | --------- | ------------------------------------------------------------------ |
| `framework` | `string` | Detected framework (`next`, `vite`, `react-router`, `start`, etc.) |
| `frameworkVersion` | `string` | Framework version (e.g. `15.2.4`) |
| `isSrcDir` | `boolean` | Whether the project uses a `src/` directory |
| `isRSC` | `boolean` | Whether React Server Components are enabled |
| `isTsx` | `boolean` | Whether the project uses TypeScript |
| `tailwindVersion` | `string` | `"v3"` or `"v4"` |
| `tailwindConfigFile` | `string` | Path to the Tailwind config file |
| `tailwindCssFile` | `string` | Path to the global CSS file |
| `aliasPrefix` | `string` | Import alias prefix (e.g. `@`, `~`, `@/`) |
| `packageManager` | `string` | Detected package manager (`npm`, `pnpm`, `yarn`, `bun`) |
**Components.json fields:**
| Field | Type | Meaning |
| -------------------- | --------- | ------------------------------------------------------------------------------------------ |
| `base` | `string` | Primitive library (`radix` or `base`) — determines component APIs and available props |
| `style` | `string` | Visual style (e.g. `nova`, `vega`) |
| `rsc` | `boolean` | RSC flag from config |
| `tsx` | `boolean` | TypeScript flag |
| `tailwind.config` | `string` | Tailwind config path |
| `tailwind.css` | `string` | Global CSS path — this is where custom CSS variables go |
| `iconLibrary` | `string` | Icon library — determines icon import package (e.g. `lucide-react`, `@tabler/icons-react`) |
| `aliases.components` | `string` | Component import alias (e.g. `@/components`) |
| `aliases.utils` | `string` | Utils import alias (e.g. `@/lib/utils`) |
| `aliases.ui` | `string` | UI component alias (e.g. `@/components/ui`) |
| `aliases.lib` | `string` | Lib alias (e.g. `@/lib`) |
| `aliases.hooks` | `string` | Hooks alias (e.g. `@/hooks`) |
| `resolvedPaths` | `object` | Absolute file-system paths for each alias |
| `registries` | `object` | Configured custom registries |
**Links fields:**
The `info` output includes a **Links** section with templated URLs for component docs, source, and examples. For resolved URLs, use `npx shadcn@latest docs <component>` instead.
### `build` — Build a custom registry
```bash
npx shadcn@latest build [registry] [options]
```
Builds `registry.json` into individual JSON files for distribution. Default input: `./registry.json`, default output: `./public/r`.
| Flag | Short | Description | Default |
| ----------------- | ----- | ----------------- | ------------ |
| `--output <path>` | `-o` | Output directory | `./public/r` |
| `--cwd <cwd>` | `-c` | Working directory | current |
---
## Templates
| Value | Framework | Monorepo support |
| -------------- | -------------- | ---------------- |
| `next` | Next.js | Yes |
| `vite` | Vite | Yes |
| `start` | TanStack Start | Yes |
| `react-router` | React Router | Yes |
| `astro` | Astro | Yes |
| `laravel` | Laravel | No |
All templates support monorepo scaffolding via the `--monorepo` flag. When passed, the CLI uses a monorepo-specific template directory (e.g. `next-monorepo`, `vite-monorepo`). When neither `--monorepo` nor `--no-monorepo` is passed, the CLI prompts interactively. Laravel does not support monorepo scaffolding.
---
## Presets
Three ways to specify a preset via `--preset`:
1. **Named:** `--preset base-nova` or `--preset radix-nova`
2. **Code:** `--preset a2r6bw` (base62 string, starts with lowercase `a`)
3. **URL:** `--preset "https://ui.shadcn.com/init?base=radix&style=nova&..."`
> **IMPORTANT:** Never try to decode, fetch, or resolve preset codes manually. Preset codes are opaque — pass them directly to `npx shadcn@latest init --preset <code>` and let the CLI handle resolution.
## Switching Presets
Ask the user first: **reinstall**, **merge**, or **skip** existing components?
- **Re-install** → `npx shadcn@latest init --preset <code> --force --reinstall`. Overwrites all component files with the new preset styles. Use when the user hasn't customized components.
- **Merge** → `npx shadcn@latest init --preset <code> --force --no-reinstall`, then run `npx shadcn@latest info` to get the list of installed components and use the [smart merge workflow](./SKILL.md#updating-components) to update them one by one, preserving local changes. Use when the user has customized components.
- **Skip** → `npx shadcn@latest init --preset <code> --force --no-reinstall`. Only updates config and CSS variables, leaves existing components as-is.

# Customization & Theming
Components reference semantic CSS variable tokens. Change the variables to change every component.
## Contents
- How it works (CSS variables → Tailwind utilities → components)
- Color variables and OKLCH format
- Dark mode setup
- Changing the theme (presets, CSS variables)
- Adding custom colors (Tailwind v3 and v4)
- Border radius
- Customizing components (variants, className, wrappers)
- Checking for updates
---
## How It Works
1. CSS variables defined in `:root` (light) and `.dark` (dark mode).
2. Tailwind maps them to utilities: `bg-primary`, `text-muted-foreground`, etc.
3. Components use these utilities — changing a variable changes all components that reference it.
---
## Color Variables
Every color follows the `name` / `name-foreground` convention. The base variable is for backgrounds, `-foreground` is for text/icons on that background.
| Variable | Purpose |
| -------------------------------------------- | -------------------------------- |
| `--background` / `--foreground` | Page background and default text |
| `--card` / `--card-foreground` | Card surfaces |
| `--primary` / `--primary-foreground` | Primary buttons and actions |
| `--secondary` / `--secondary-foreground` | Secondary actions |
| `--muted` / `--muted-foreground` | Muted/disabled states |
| `--accent` / `--accent-foreground` | Hover and accent states |
| `--destructive` / `--destructive-foreground` | Error and destructive actions |
| `--border` | Default border color |
| `--input` | Form input borders |
| `--ring` | Focus ring color |
| `--chart-1` through `--chart-5` | Chart/data visualization |
| `--sidebar-*` | Sidebar-specific colors |
| `--surface` / `--surface-foreground` | Secondary surface |
Colors use OKLCH: `--primary: oklch(0.205 0 0)` where values are lightness (0–1), chroma (0 = gray), and hue (0–360).
---
## Dark Mode
Class-based toggle via `.dark` on the root element. In Next.js, use `next-themes`:
```tsx
import { ThemeProvider } from "next-themes"
<ThemeProvider attribute="class" defaultTheme="system" enableSystem>
{children}
</ThemeProvider>
```
---
## Changing the Theme
```bash
# Apply a preset code from ui.shadcn.com.
npx shadcn@latest init --preset a2r6bw --force
# Switch to a named preset.
npx shadcn@latest init --preset radix-nova --force
npx shadcn@latest init --reinstall # update existing components to match
# Use a custom theme URL.
npx shadcn@latest init --preset "https://ui.shadcn.com/init?base=radix&style=nova&theme=blue&..." --force
```
Or edit CSS variables directly in `globals.css`.
---
## Adding Custom Colors
Add variables to the file at `tailwindCssFile` from `npx shadcn@latest info` (typically `globals.css`). Never create a new CSS file for this.
```css
/* 1. Define in the global CSS file. */
:root {
--warning: oklch(0.84 0.16 84);
--warning-foreground: oklch(0.28 0.07 46);
}
.dark {
--warning: oklch(0.41 0.11 46);
--warning-foreground: oklch(0.99 0.02 95);
}
```
```css
/* 2a. Register with Tailwind v4 (@theme inline). */
@theme inline {
--color-warning: var(--warning);
--color-warning-foreground: var(--warning-foreground);
}
```
When `tailwindVersion` is `"v3"` (check via `npx shadcn@latest info`), register in `tailwind.config.js` instead:
```js
// 2b. Register with Tailwind v3 (tailwind.config.js).
module.exports = {
theme: {
extend: {
colors: {
warning: "oklch(var(--warning) / <alpha-value>)",
"warning-foreground":
"oklch(var(--warning-foreground) / <alpha-value>)",
},
},
},
}
```
```tsx
// 3. Use in components.
<div className="bg-warning text-warning-foreground">Warning</div>
```
---
## Border Radius
`--radius` controls border radius globally. Components derive values from it (`rounded-lg` = `var(--radius)`, `rounded-md` = `calc(var(--radius) - 2px)`).
---
## Customizing Components
See also: [rules/styling.md](./rules/styling.md) for Incorrect/Correct examples.
Prefer these approaches in order:
### 1. Built-in variants
```tsx
<Button variant="outline" size="sm">Click</Button>
```
### 2. Tailwind classes via `className`
```tsx
<Card className="max-w-md mx-auto">...</Card>
```
### 3. Add a new variant
Edit the component source to add a variant via `cva`:
```tsx
// components/ui/button.tsx
warning: "bg-warning text-warning-foreground hover:bg-warning/90",
```
### 4. Wrapper components
Compose shadcn/ui primitives into higher-level components:
```tsx
export function ConfirmDialog({ title, description, onConfirm, children }) {
return (
<AlertDialog>
<AlertDialogTrigger asChild>{children}</AlertDialogTrigger>
<AlertDialogContent>
<AlertDialogHeader>
<AlertDialogTitle>{title}</AlertDialogTitle>
<AlertDialogDescription>{description}</AlertDialogDescription>
</AlertDialogHeader>
<AlertDialogFooter>
<AlertDialogCancel>Cancel</AlertDialogCancel>
<AlertDialogAction onClick={onConfirm}>Confirm</AlertDialogAction>
</AlertDialogFooter>
</AlertDialogContent>
</AlertDialog>
)
}
```
---
## Checking for Updates
```bash
npx shadcn@latest add button --diff
```
To preview exactly what would change before updating, use `--dry-run` and `--diff`:
```bash
npx shadcn@latest add button --dry-run # see all affected files
npx shadcn@latest add button --diff button.tsx # see the diff for a specific file
```

# shadcn MCP Server
The CLI includes an MCP server that lets AI assistants search, browse, view, and install components from registries.
---
## Setup
```bash
shadcn mcp # start the MCP server (stdio)
shadcn mcp init # write config for your editor
```
Editor config files:
| Editor | Config file |
|--------|------------|
| Claude Code | `.mcp.json` |
| Cursor | `.cursor/mcp.json` |
| VS Code | `.vscode/mcp.json` |
| OpenCode | `opencode.json` |
| Codex | `~/.codex/config.toml` (manual) |
---
## Tools
> **Tip:** MCP tools handle registry operations (search, view, install). For project configuration (aliases, framework, Tailwind version), use `npx shadcn@latest info` — there is no MCP equivalent.
### `shadcn:get_project_registries`
Returns registry names from `components.json`. Errors if no `components.json` exists.
**Input:** none
### `shadcn:list_items_in_registries`
Lists all items from one or more registries.
**Input:** `registries` (string[]), `limit` (number, optional), `offset` (number, optional)
### `shadcn:search_items_in_registries`
Fuzzy search across registries.
**Input:** `registries` (string[]), `query` (string), `limit` (number, optional), `offset` (number, optional)
### `shadcn:view_items_in_registries`
View item details including full file contents.
**Input:** `items` (string[]) — e.g. `["@shadcn/button", "@shadcn/card"]`
### `shadcn:get_item_examples_from_registries`
Find usage examples and demos with source code.
**Input:** `registries` (string[]), `query` (string) — e.g. `"accordion-demo"`, `"button example"`
### `shadcn:get_add_command_for_items`
Returns the CLI install command.
**Input:** `items` (string[]) — e.g. `["@shadcn/button"]`
### `shadcn:get_audit_checklist`
Returns a checklist for verifying components (imports, deps, lint, TypeScript).
**Input:** none
---
## Configuring Registries
Registries are set in `components.json`. The `@shadcn` registry is always built-in.
```json
{
"registries": {
"@acme": "https://acme.com/r/{name}.json",
"@private": {
"url": "https://private.com/r/{name}.json",
"headers": { "Authorization": "Bearer ${MY_TOKEN}" }
}
}
}
```
- Names must start with `@`.
- URLs must contain `{name}`.
- `${VAR}` references are resolved from environment variables.
Community registry index: `https://ui.shadcn.com/r/registries.json`

# Base vs Radix
API differences between `base` and `radix`. Check the `base` field from `npx shadcn@latest info`.
## Contents
- Composition: asChild vs render
- Button / trigger as non-button element
- Select (items prop, placeholder, positioning, multiple, object values)
- ToggleGroup (type vs multiple)
- Slider (scalar vs array)
- Accordion (type and defaultValue)
---
## Composition: asChild (radix) vs render (base)
Radix uses `asChild` to replace the default element. Base uses `render`. Don't wrap triggers in extra elements.
**Incorrect:**
```tsx
<DialogTrigger>
<div>
<Button>Open</Button>
</div>
</DialogTrigger>
```
**Correct (radix):**
```tsx
<DialogTrigger asChild>
<Button>Open</Button>
</DialogTrigger>
```
**Correct (base):**
```tsx
<DialogTrigger render={<Button />}>Open</DialogTrigger>
```
This applies to all trigger and close components: `DialogTrigger`, `SheetTrigger`, `AlertDialogTrigger`, `DropdownMenuTrigger`, `PopoverTrigger`, `TooltipTrigger`, `CollapsibleTrigger`, `DialogClose`, `SheetClose`, `NavigationMenuLink`, `BreadcrumbLink`, `SidebarMenuButton`, `Badge`, `Item`.
---
## Button / trigger as non-button element (base only)
When `render` changes an element to a non-button (`<a>`, `<span>`), add `nativeButton={false}`.
**Incorrect (base):** missing `nativeButton={false}`.
```tsx
<Button render={<a href="/docs" />}>Read the docs</Button>
```
**Correct (base):**
```tsx
<Button render={<a href="/docs" />} nativeButton={false}>
Read the docs
</Button>
```
**Correct (radix):**
```tsx
<Button asChild>
<a href="/docs">Read the docs</a>
</Button>
```
Same for triggers whose `render` is not a `Button`:
```tsx
// base.
<PopoverTrigger render={<InputGroupAddon />} nativeButton={false}>
Pick date
</PopoverTrigger>
```
---
## Select
**items prop (base only).** Base requires an `items` prop on the root. Radix uses inline JSX only.
**Incorrect (base):**
```tsx
<Select>
<SelectTrigger><SelectValue placeholder="Select a fruit" /></SelectTrigger>
</Select>
```
**Correct (base):**
```tsx
const items = [
{ label: "Select a fruit", value: null },
{ label: "Apple", value: "apple" },
{ label: "Banana", value: "banana" },
]
<Select items={items}>
<SelectTrigger>
<SelectValue />
</SelectTrigger>
<SelectContent>
<SelectGroup>
{items.map((item) => (
<SelectItem key={item.value} value={item.value}>{item.label}</SelectItem>
))}
</SelectGroup>
</SelectContent>
</Select>
```
**Correct (radix):**
```tsx
<Select>
<SelectTrigger>
<SelectValue placeholder="Select a fruit" />
</SelectTrigger>
<SelectContent>
<SelectGroup>
<SelectItem value="apple">Apple</SelectItem>
<SelectItem value="banana">Banana</SelectItem>
</SelectGroup>
</SelectContent>
</Select>
```
**Placeholder.** Base uses a `{ value: null }` item in the items array. Radix uses `<SelectValue placeholder="...">`.
**Content positioning.** Base uses `alignItemWithTrigger`. Radix uses `position`.
```tsx
// base.
<SelectContent alignItemWithTrigger={false} side="bottom">
// radix.
<SelectContent position="popper">
```
---
## Select — multiple selection and object values (base only)
Base supports `multiple`, render-function children on `SelectValue`, and object values with `itemToStringValue`. Radix is single-select with string values only.
**Correct (base — multiple selection):**
```tsx
<Select items={items} multiple defaultValue={[]}>
<SelectTrigger>
<SelectValue>
{(value: string[]) => value.length === 0 ? "Select fruits" : `${value.length} selected`}
</SelectValue>
</SelectTrigger>
...
</Select>
```
**Correct (base — object values):**
```tsx
<Select defaultValue={plans[0]} itemToStringValue={(plan) => plan.name}>
<SelectTrigger>
<SelectValue>{(value) => value.name}</SelectValue>
</SelectTrigger>
...
</Select>
```
---
## ToggleGroup
Base uses a `multiple` boolean prop. Radix uses `type="single"` or `type="multiple"`.
**Incorrect (base):**
```tsx
<ToggleGroup type="single" defaultValue="daily">
<ToggleGroupItem value="daily">Daily</ToggleGroupItem>
</ToggleGroup>
```
**Correct (base):**
```tsx
// Single (no prop needed), defaultValue is always an array.
<ToggleGroup defaultValue={["daily"]} spacing={2}>
<ToggleGroupItem value="daily">Daily</ToggleGroupItem>
<ToggleGroupItem value="weekly">Weekly</ToggleGroupItem>
</ToggleGroup>
// Multi-selection.
<ToggleGroup multiple>
<ToggleGroupItem value="bold">Bold</ToggleGroupItem>
<ToggleGroupItem value="italic">Italic</ToggleGroupItem>
</ToggleGroup>
```
**Correct (radix):**
```tsx
// Single, defaultValue is a string.
<ToggleGroup type="single" defaultValue="daily" spacing={2}>
<ToggleGroupItem value="daily">Daily</ToggleGroupItem>
<ToggleGroupItem value="weekly">Weekly</ToggleGroupItem>
</ToggleGroup>
// Multi-selection.
<ToggleGroup type="multiple">
<ToggleGroupItem value="bold">Bold</ToggleGroupItem>
<ToggleGroupItem value="italic">Italic</ToggleGroupItem>
</ToggleGroup>
```
**Controlled single value:**
```tsx
// base — wrap/unwrap arrays.
const [value, setValue] = React.useState("normal")
<ToggleGroup value={[value]} onValueChange={(v) => setValue(v[0])}>
// radix — plain string.
const [value, setValue] = React.useState("normal")
<ToggleGroup type="single" value={value} onValueChange={setValue}>
```
---
## Slider
Base accepts a plain number for a single thumb. Radix always requires an array.
**Incorrect (base):**
```tsx
<Slider defaultValue={[50]} max={100} step={1} />
```
**Correct (base):**
```tsx
<Slider defaultValue={50} max={100} step={1} />
```
**Correct (radix):**
```tsx
<Slider defaultValue={[50]} max={100} step={1} />
```
Both use arrays for range sliders. Controlled `onValueChange` in base may need a cast:
```tsx
// base.
const [value, setValue] = React.useState([0.3, 0.7])
<Slider value={value} onValueChange={(v) => setValue(v as number[])} />
// radix.
const [value, setValue] = React.useState([0.3, 0.7])
<Slider value={value} onValueChange={setValue} />
```
---
## Accordion
Radix requires `type="single"` or `type="multiple"` and supports `collapsible`. `defaultValue` is a string. Base uses no `type` prop, uses `multiple` boolean, and `defaultValue` is always an array.
**Incorrect (base):**
```tsx
<Accordion type="single" collapsible defaultValue="item-1">
<AccordionItem value="item-1">...</AccordionItem>
</Accordion>
```
**Correct (base):**
```tsx
<Accordion defaultValue={["item-1"]}>
<AccordionItem value="item-1">...</AccordionItem>
</Accordion>
// Multi-select.
<Accordion multiple defaultValue={["item-1", "item-2"]}>
<AccordionItem value="item-1">...</AccordionItem>
<AccordionItem value="item-2">...</AccordionItem>
</Accordion>
```
**Correct (radix):**
```tsx
<Accordion type="single" collapsible defaultValue="item-1">
<AccordionItem value="item-1">...</AccordionItem>
</Accordion>
```

# Component Composition
## Contents
- Items always inside their Group component
- Callouts use Alert
- Empty states use Empty component
- Toast notifications use sonner
- Choosing between overlay components
- Dialog, Sheet, and Drawer always need a Title
- Card structure
- Button has no isPending or isLoading prop
- TabsTrigger must be inside TabsList
- Avatar always needs AvatarFallback
- Use Separator instead of raw hr or border divs
- Use Skeleton for loading placeholders
- Use Badge instead of custom styled spans
---
## Items always inside their Group component
Never render items directly inside the content container.
**Incorrect:**
```tsx
<SelectContent>
<SelectItem value="apple">Apple</SelectItem>
<SelectItem value="banana">Banana</SelectItem>
</SelectContent>
```
**Correct:**
```tsx
<SelectContent>
<SelectGroup>
<SelectItem value="apple">Apple</SelectItem>
<SelectItem value="banana">Banana</SelectItem>
</SelectGroup>
</SelectContent>
```
This applies to all group-based components:
| Item | Group |
|------|-------|
| `SelectItem`, `SelectLabel` | `SelectGroup` |
| `DropdownMenuItem`, `DropdownMenuLabel`, `DropdownMenuSub` | `DropdownMenuGroup` |
| `MenubarItem` | `MenubarGroup` |
| `ContextMenuItem` | `ContextMenuGroup` |
| `CommandItem` | `CommandGroup` |
---
## Callouts use Alert
```tsx
<Alert>
<AlertTitle>Warning</AlertTitle>
<AlertDescription>Something needs attention.</AlertDescription>
</Alert>
```
---
## Empty states use Empty component
```tsx
<Empty>
<EmptyHeader>
<EmptyMedia variant="icon"><FolderIcon /></EmptyMedia>
<EmptyTitle>No projects yet</EmptyTitle>
<EmptyDescription>Get started by creating a new project.</EmptyDescription>
</EmptyHeader>
<EmptyContent>
<Button>Create Project</Button>
</EmptyContent>
</Empty>
```
---
## Toast notifications use sonner
```tsx
import { toast } from "sonner"
toast.success("Changes saved.")
toast.error("Something went wrong.")
toast("File deleted.", {
action: { label: "Undo", onClick: () => undoDelete() },
})
```
---
## Choosing between overlay components
| Use case | Component |
|----------|-----------|
| Focused task that requires input | `Dialog` |
| Destructive action confirmation | `AlertDialog` |
| Side panel with details or filters | `Sheet` |
| Mobile-first bottom panel | `Drawer` |
| Quick info on hover | `HoverCard` |
| Small contextual content on click | `Popover` |
---
## Dialog, Sheet, and Drawer always need a Title
`DialogTitle`, `SheetTitle`, `DrawerTitle` are required for accessibility. Use `className="sr-only"` if visually hidden.
```tsx
<DialogContent>
<DialogHeader>
<DialogTitle>Edit Profile</DialogTitle>
<DialogDescription>Update your profile.</DialogDescription>
</DialogHeader>
...
</DialogContent>
```
---
## Card structure
Use full composition — don't dump everything into `CardContent`:
```tsx
<Card>
<CardHeader>
<CardTitle>Team Members</CardTitle>
<CardDescription>Manage your team.</CardDescription>
</CardHeader>
<CardContent>...</CardContent>
<CardFooter>
<Button>Invite</Button>
</CardFooter>
</Card>
```
---
## Button has no isPending or isLoading prop
Compose with `Spinner` + `data-icon` + `disabled`:
```tsx
<Button disabled>
<Spinner data-icon="inline-start" />
Saving...
</Button>
```
---
## TabsTrigger must be inside TabsList
Never render `TabsTrigger` directly inside `Tabs` — always wrap in `TabsList`:
```tsx
<Tabs defaultValue="account">
<TabsList>
<TabsTrigger value="account">Account</TabsTrigger>
<TabsTrigger value="password">Password</TabsTrigger>
</TabsList>
<TabsContent value="account">...</TabsContent>
</Tabs>
```
---
## Avatar always needs AvatarFallback
Always include `AvatarFallback` for when the image fails to load:
```tsx
<Avatar>
<AvatarImage src="/avatar.png" alt="User" />
<AvatarFallback>JD</AvatarFallback>
</Avatar>
```
---
## Use existing components instead of custom markup
| Instead of | Use |
|---|---|
| `<hr>` or `<div className="border-t">` | `<Separator />` |
| `<div className="animate-pulse">` with styled divs | `<Skeleton className="h-4 w-3/4" />` |
| `<span className="rounded-full bg-green-100 ...">` | `<Badge variant="secondary">` |

# Forms & Inputs
## Contents
- Forms use FieldGroup + Field
- InputGroup requires InputGroupInput/InputGroupTextarea
- Buttons inside inputs use InputGroup + InputGroupAddon
- Option sets (2–7 choices) use ToggleGroup
- FieldSet + FieldLegend for grouping related fields
- Field validation and disabled states
---
## Forms use FieldGroup + Field
Always use `FieldGroup` + `Field` — never raw `div` with `space-y-*`:
```tsx
<FieldGroup>
<Field>
<FieldLabel htmlFor="email">Email</FieldLabel>
<Input id="email" type="email" />
</Field>
<Field>
<FieldLabel htmlFor="password">Password</FieldLabel>
<Input id="password" type="password" />
</Field>
</FieldGroup>
```
Use `Field orientation="horizontal"` for settings pages. Use `FieldLabel className="sr-only"` for visually hidden labels.
**Choosing form controls:**
- Simple text input → `Input`
- Dropdown with predefined options → `Select`
- Searchable dropdown → `Combobox`
- Native HTML select (no JS) → `native-select`
- Boolean toggle → `Switch` (for settings) or `Checkbox` (for forms)
- Single choice from few options → `RadioGroup`
- Toggle between 2–5 options → `ToggleGroup` + `ToggleGroupItem`
- OTP/verification code → `InputOTP`
- Multi-line text → `Textarea`
---
## InputGroup requires InputGroupInput/InputGroupTextarea
Never use raw `Input` or `Textarea` inside an `InputGroup`.
**Incorrect:**
```tsx
<InputGroup>
<Input placeholder="Search..." />
</InputGroup>
```
**Correct:**
```tsx
import { InputGroup, InputGroupInput } from "@/components/ui/input-group"
<InputGroup>
<InputGroupInput placeholder="Search..." />
</InputGroup>
```
---
## Buttons inside inputs use InputGroup + InputGroupAddon
Never place a `Button` directly inside or adjacent to an `Input` with custom positioning.
**Incorrect:**
```tsx
<div className="relative">
<Input placeholder="Search..." className="pr-10" />
<Button className="absolute right-0 top-0" size="icon">
<SearchIcon />
</Button>
</div>
```
**Correct:**
```tsx
import { InputGroup, InputGroupInput, InputGroupAddon } from "@/components/ui/input-group"
<InputGroup>
<InputGroupInput placeholder="Search..." />
<InputGroupAddon>
<Button size="icon">
<SearchIcon data-icon="inline-start" />
</Button>
</InputGroupAddon>
</InputGroup>
```
---
## Option sets (2–7 choices) use ToggleGroup
Don't manually loop `Button` components with active state.
**Incorrect:**
```tsx
const [selected, setSelected] = useState("daily")
<div className="flex gap-2">
{["daily", "weekly", "monthly"].map((option) => (
<Button
key={option}
variant={selected === option ? "default" : "outline"}
onClick={() => setSelected(option)}
>
{option}
</Button>
))}
</div>
```
**Correct:**
```tsx
import { ToggleGroup, ToggleGroupItem } from "@/components/ui/toggle-group"
<ToggleGroup spacing={2}>
<ToggleGroupItem value="daily">Daily</ToggleGroupItem>
<ToggleGroupItem value="weekly">Weekly</ToggleGroupItem>
<ToggleGroupItem value="monthly">Monthly</ToggleGroupItem>
</ToggleGroup>
```
Combine with `Field` for labelled toggle groups:
```tsx
<Field orientation="horizontal">
<FieldTitle id="theme-label">Theme</FieldTitle>
<ToggleGroup aria-labelledby="theme-label" spacing={2}>
<ToggleGroupItem value="light">Light</ToggleGroupItem>
<ToggleGroupItem value="dark">Dark</ToggleGroupItem>
<ToggleGroupItem value="system">System</ToggleGroupItem>
</ToggleGroup>
</Field>
```
> **Note:** `defaultValue` and `type`/`multiple` props differ between base and radix. See [base-vs-radix.md](./base-vs-radix.md#togglegroup).
---
## FieldSet + FieldLegend for grouping related fields
Use `FieldSet` + `FieldLegend` for related checkboxes, radios, or switches — not `div` with a heading:
```tsx
<FieldSet>
<FieldLegend variant="label">Preferences</FieldLegend>
<FieldDescription>Select all that apply.</FieldDescription>
<FieldGroup className="gap-3">
<Field orientation="horizontal">
<Checkbox id="dark" />
<FieldLabel htmlFor="dark" className="font-normal">Dark mode</FieldLabel>
</Field>
</FieldGroup>
</FieldSet>
```
---
## Field validation and disabled states
Both attributes are needed — `data-invalid`/`data-disabled` styles the field (label, description), while `aria-invalid`/`disabled` styles the control.
```tsx
// Invalid.
<Field data-invalid>
<FieldLabel htmlFor="email">Email</FieldLabel>
<Input id="email" aria-invalid />
<FieldDescription>Invalid email address.</FieldDescription>
</Field>
// Disabled.
<Field data-disabled>
<FieldLabel htmlFor="email">Email</FieldLabel>
<Input id="email" disabled />
</Field>
```
Works for all controls: `Input`, `Textarea`, `Select`, `Checkbox`, `RadioGroupItem`, `Switch`, `Slider`, `NativeSelect`, `InputOTP`.

# Icons
**Always use the project's configured `iconLibrary` for imports.** Check the `iconLibrary` field from project context: `lucide` → `lucide-react`, `tabler` → `@tabler/icons-react`, etc. Never assume `lucide-react`.
---
## Icons in Button use data-icon attribute
Add `data-icon="inline-start"` (prefix) or `data-icon="inline-end"` (suffix) to the icon. No sizing classes on the icon.
**Incorrect:**
```tsx
<Button>
<SearchIcon className="mr-2 size-4" />
Search
</Button>
```
**Correct:**
```tsx
<Button>
<SearchIcon data-icon="inline-start"/>
Search
</Button>
<Button>
Next
<ArrowRightIcon data-icon="inline-end"/>
</Button>
```
---
## No sizing classes on icons inside components
Components handle icon sizing via CSS. Don't add `size-4`, `w-4 h-4`, or other sizing classes to icons inside `Button`, `DropdownMenuItem`, `Alert`, `Sidebar*`, or other shadcn components. Unless the user explicitly asks for custom icon sizes.
**Incorrect:**
```tsx
<Button>
<SearchIcon className="size-4" data-icon="inline-start" />
Search
</Button>
<DropdownMenuItem>
<SettingsIcon className="mr-2 size-4" />
Settings
</DropdownMenuItem>
```
**Correct:**
```tsx
<Button>
<SearchIcon data-icon="inline-start" />
Search
</Button>
<DropdownMenuItem>
<SettingsIcon />
Settings
</DropdownMenuItem>
```
---
## Pass icons as component objects, not string keys
Use `icon={CheckIcon}`, not a string key to a lookup map.
**Incorrect:**
```tsx
const iconMap = {
check: CheckIcon,
alert: AlertIcon,
}
function StatusBadge({ icon }: { icon: string }) {
const Icon = iconMap[icon]
return <Icon />
}
<StatusBadge icon="check" />
```
**Correct:**
```tsx
// Import from the project's configured iconLibrary (e.g. lucide-react, @tabler/icons-react).
import { CheckIcon } from "lucide-react"
function StatusBadge({ icon: Icon }: { icon: React.ComponentType }) {
return <Icon />
}
<StatusBadge icon={CheckIcon} />
```

# Styling & Customization
See [customization.md](../customization.md) for theming, CSS variables, and adding custom colors.
## Contents
- Semantic colors
- Built-in variants first
- className for layout only
- No space-x-* / space-y-*
- Prefer size-* over w-* h-* when equal
- Prefer truncate shorthand
- No manual dark: color overrides
- Use cn() for conditional classes
- No manual z-index on overlay components
---
## Semantic colors
**Incorrect:**
```tsx
<div className="bg-blue-500 text-white">
<p className="text-gray-600">Secondary text</p>
</div>
```
**Correct:**
```tsx
<div className="bg-primary text-primary-foreground">
<p className="text-muted-foreground">Secondary text</p>
</div>
```
---
## No raw color values for status/state indicators
For positive, negative, or status indicators, use Badge variants, semantic tokens like `text-destructive`, or define custom CSS variables — don't reach for raw Tailwind colors.
**Incorrect:**
```tsx
<span className="text-emerald-600">+20.1%</span>
<span className="text-green-500">Active</span>
<span className="text-red-600">-3.2%</span>
```
**Correct:**
```tsx
<Badge variant="secondary">+20.1%</Badge>
<Badge>Active</Badge>
<span className="text-destructive">-3.2%</span>
```
If you need a success/positive color that doesn't exist as a semantic token, use a Badge variant or ask the user about adding a custom CSS variable to the theme (see [customization.md](../customization.md)).
---
## Built-in variants first
**Incorrect:**
```tsx
<Button className="border border-input bg-transparent hover:bg-accent">
Click me
</Button>
```
**Correct:**
```tsx
<Button variant="outline">Click me</Button>
```
---
## className for layout only
Use `className` for layout (e.g. `max-w-md`, `mx-auto`, `mt-4`), **not** for overriding component colors or typography. To change colors, use semantic tokens, built-in variants, or CSS variables.
**Incorrect:**
```tsx
<Card className="bg-blue-100 text-blue-900 font-bold">
<CardContent>Dashboard</CardContent>
</Card>
```
**Correct:**
```tsx
<Card className="max-w-md mx-auto">
<CardContent>Dashboard</CardContent>
</Card>
```
To customize a component's appearance, prefer these approaches in order:
1. **Built-in variants** — `variant="outline"`, `variant="destructive"`, etc.
2. **Semantic color tokens** — `bg-primary`, `text-muted-foreground`.
3. **CSS variables** — define custom colors in the global CSS file (see [customization.md](../customization.md)).
---
## No space-x-* / space-y-*
Use `gap-*` instead. `space-y-4` → `flex flex-col gap-4`. `space-x-2` → `flex gap-2`.
```tsx
<div className="flex flex-col gap-4">
<Input />
<Input />
<Button>Submit</Button>
</div>
```
---
## Prefer size-* over w-* h-* when equal
`size-10` not `w-10 h-10`. Applies to icons, avatars, skeletons, etc.
---
## Prefer truncate shorthand
`truncate` not `overflow-hidden text-ellipsis whitespace-nowrap`.
---
## No manual dark: color overrides
Use semantic tokens — they handle light/dark via CSS variables. `bg-background text-foreground` not `bg-white dark:bg-gray-950`.
---
## Use cn() for conditional classes
Use the `cn()` utility from the project for conditional or merged class names. Don't write manual ternaries in className strings.
**Incorrect:**
```tsx
<div className={`flex items-center ${isActive ? "bg-primary text-primary-foreground" : "bg-muted"}`}>
```
**Correct:**
```tsx
import { cn } from "@/lib/utils"
<div className={cn("flex items-center", isActive ? "bg-primary text-primary-foreground" : "bg-muted")}>
```
---
## No manual z-index on overlay components
`Dialog`, `Sheet`, `Drawer`, `AlertDialog`, `DropdownMenu`, `Popover`, `Tooltip`, `HoverCard` handle their own stacking. Never add `z-50` or `z-[999]`.

# StyleSeed Design Review
## Overview
A UI reads as "AI-generated" not because the components are ugly, but because the **parts
don't agree with each other** — mixed corner radii, three accent colors, pure-black text,
no hierarchy, missing states, robotic copy. This skill reviews a UI file (or a whole
directory) against a concrete design rubric, scores it 0–100, and returns a prioritized
fix list. It reviews and recommends; it never edits or deletes without you asking.
Full rule set (74 rules) and components: https://github.com/bitjaru/styleseed
## When to use
- A React / Tailwind / HTML UI "looks off," generic, or unfinished and you can't say why.
- You want a design score / pre-ship check.
- The user asks to make UI "look professional / polished / designed, not AI-generated."
- After generating UI, to verify it before shipping.
## How to review
Read the file(s). Score these **seven categories** (total 100); start each at full marks
and subtract for violations you can cite by line. Be specific and evidence-based.
### 1. Coherence — 20 (the #1 "AI-generated" tell)
One choice per axis, applied everywhere. Deduct for each **mixed** axis:
- mixed corner radii — e.g. a sharp card with pill buttons (−6)
- two or more accent colors used for emphasis (−5)
- **emoji used as UI icons** (🚗🧺⭐ as list/nav/status/category markers) — injects many uncontrolled hues; use one line-icon set in currentColor (−6)
- mixed shadow languages / light directions (−3)
- mixed icon families, fill modes, or stroke weights (−3)
- inconsistent control heights (buttons/inputs differ) (−3)
### 2. Color discipline — 16
- pure black (`#000` / `text-black`) text — the refined black is ~`#2A2A2A` (−4 each, cap −8)
- hardcoded hex where a semantic token exists (−2 each, cap −6)
- **a normal / OK / default ("보통") state shown in a status color** instead of neutral grey (−4)
- **status color on most/every row** (no severity hierarchy — color should mark the minority that needs attention) (−4)
- **decorative hues** — gold stars, rainbow category dots, a different color per card — instead of accent/grey (−3)
- status conveyed by color alone, no icon/text (−4)
- contrast below WCAG AA (4.5:1 body, 3:1 large/UI) (−6)
### 3. Hierarchy & typography — 16
- number and its unit not ~2:1 (48px number / 24px unit) (−4)
- everything the same size and weight, no clear primary (−5)
- arbitrary font sizes; no scale (−4)
- wrong line-height (loose on display, cramped on body) (−3)
### 4. Layout & spacing — 12
- content on a bare page background, not in cards (−6)
- off-grid spacing (7/13/19px instead of an 8px scale) (−3)
- the gap *around* a group not larger than the gap *inside* it (−3)
- the same section type repeated in a row (−4)
### 5. States — 12
- missing empty / loading / error state on a data surface (−5 each, cap −10)
- empty state with no next action; error that blames instead of helping (−4)
### 6. UX writing — 12
- buttons that don't name the action ("Submit" / "OK" instead of "Send $2,400") (−4)
- error copy that blames or uses system-speak ("Invalid input", "An error occurred") (−4)
- two terms for one concept (delete vs remove); filler words ("please", "successfully") (−2)
### 7. Motion & polish — 12
- ad-hoc fades instead of one consistent, named feel (−3)
- motion that delays content or blocks an action (−4)
- no `prefers-reduced-motion` handling on custom motion (−3)
- a single hard black shadow instead of a layered, low-opacity, tinted one (−2)
Clamp each category at 0; sum to a total. Bands: 90+ A · 80–89 B · 70–79 C · 60–69 D · <60 F.
## Output format
```
## Design Score: 72 / 100 (src/Dashboard.tsx) C
Coherence 13/20 sharp cards (l.22) + pill buttons (l.48); 3 accent hues
Color discipline 12/16 #000 headings (l.12, 40)
Hierarchy & type 15/16 number/unit 1:1 on hero (l.18)
Layout & spacing 10/12 two identical KPI rows (l.22-31)
States 7/12 no empty/loading state on the orders list
UX writing 8/12 "Submit" button (l.55); "Invalid input" (l.61)
Motion & polish 10/12 one hard black shadow (l.22)
### Fix first (highest score gain)
1. Unify radius (pick soft 8–12px) + collapse to one accent → +11 coherence/color
2. Add empty + loading states to the orders list → +7 states
3. Rename "Submit" → "Send $2,400"; "Invalid input" → "Check the card number" → +6 copy
Re-score after: ~90 / 100.
```
## Rules
- Review from real evidence (cite line numbers); never guess.
- Order the fix list by **score gain**, not severity alone — fastest path to a better number.
- For a directory: one-line score per file, then the lowest file's full breakdown.
- **Don't auto-edit.** This skill measures and recommends. Apply fixes only when asked.
- Use it as a **quality gate**: review right after generating UI, apply the fix list, and
re-review until the score clears ~80 *before showing the user* — no first-draft, incoherent
UI (rainbow status lists, emoji icons, two accents, missing states) should reach them. The
bar is a floor, not a ceiling: clear 80 and ship; don't chase 100 to delay.
---
Based on **StyleSeed** — an open-source (MIT) design engine that gives Claude Code, Cursor,
and Codex design judgment so AI-built UI stops looking generated. Full 74-rule reference,
components, brand skins, and motion: https://github.com/bitjaru/styleseed
## Limitations
- Use this skill only when the task clearly matches its upstream source and local project context.
- Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
- Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.

# AGENTS.md — Guia para IAs no projeto VentoApp
> **Estado atual (jul/2026):** 8/8 marcos concluídos, 100% da NBR 6123:2023 coberta.
> Para histórico e roadmap detalhado, consulte [`PROGRESS.md`](./PROGRESS.md).
## ⚠️ Leia ANTES de começar
**Sempre leia `PROGRESS.md` primeiro** — ele contém:
- Estado exato do projeto
- Lista de tudo que foi entregue
- Roadmap priorizado de melhorias (M9.1, M9.2, ...)
- Convenções estabelecidas
- Onde encontrar cada coisa
## Comandos essenciais
```bash
cd /root/Apps/windapp/app
npm run dev # vite dev com HMR (porta 5173)
npm run build # tsc -b && vite build (produção)
npm run lint # oxlint (sem correções automáticas)
npm test # vitest run (38 testes, modo único)
npm run test:watch # vitest watch (modo interativo)
```
> **Atenção:** neste ambiente os binários em `node_modules/.bin/` perdem o bit de execução. Se um comando reclamar `Permission denied`, rode `chmod +x node_modules/.bin/<bin>` antes.
## Validação rápida (rode sempre após mudanças)
```bash
./node_modules/.bin/tsc -b # 0 erros esperados
./node_modules/.bin/vitest run # 38/38 esperados
./node_modules/.bin/oxlint # 0 erros esperados
./node_modules/.bin/vite build # ~2s, sem erros
```
## Arquitetura
- **Cálculo puro**: `src/lib/` — funções determinísticas sem dependência de React. Tipos readonly quando possível.
- **Tabelas da norma**: `src/lib/nbr-tables/` — todas as 36 tabelas + 3 anexos da NBR 6123:2023.
- **Modules (Strategy)**: `src/lib/modules/` — padrões de cálculo por tipo de estrutura (cylinder, vault, dome, truss, tower, bridge, dynamics).
- **Estado global**: `src/store/` — Zustand. Stores separadas por domínio (vento global, galpão).
- **UI**: `src/pages/` + `src/components/` — sem lógica de cálculo pesada.

## Páginas (rotas atuais)
| Rota | Módulo | Tabelas |
|------|--------|---------|
| `/` | HomeMock | — |
| `/galpao` | Galpão retangular | 6, 7 |
| `/cilindro` | Silos, chaminés | 13 |
| `/abobada` | Abóbadas | 15-20 |
| `/cupula` | Cúpulas | 21, 22 |
| `/muros` | Muros/placas | 23 |
| `/cobertura-isolada` | Cob. isoladas | 24, 25 |
| `/barras` | Barras | 26-28 |
| `/pontes` | Pontes | 35, 36 |
| `/dinamica` | Dinâmica + vórtices | 31-34 |
| `/settings` | Tema + persistência | — |
## Convenções (manter!)
1. **TypeScript estrito**: zero `as any`, zero `// @ts-ignore`. Tipos `readonly` para tabelas.
2. **Sem comentários** exceto quando a matemática exige explicação.
3. **Imports absolutos**: `@/lib/...`, `@/components/...`, `@/store/...`.
4. **Componentes**: PascalCase em `.tsx`, kebab-case em arquivos utilitários `.ts`.
5. **Tailwind v4 + shadcn/ui**: usar `cn()` para merges, variantes do shadcn quando disponíveis.
## Princípios de cálculo (NÃO QUEBRAR)
1. **Não inventar constantes.** Toda fórmula deve vir da NBR 6123:2023.
2. **Tabela antes de fórmula.** Para S₂, usar a Tabela 3 (interpolação) por fidelidade à norma.
3. **Limites normativos.** Cpi em [-0,9 ; +0,9]. S₂ mínimo em z=5m. z_g como saturação.
4. **Cpi explícito.** Toda pressão é `p = q · (Cpe − Cpi)`. Nunca omitir Cpi.
5. **Tabela é readonly.** `Readonly<Record<...>>` previne mutação acidental.
## Workflow típico para adicionar funcionalidade
1. Identificar a seção/tabela da norma (ver `PROGRESS.md` roadmap).
2. Criar arquivo em `src/lib/nbr-tables/` com dados readonly (se aplicável).
3. Criar função de lookup (geralmente via `bilinearInterp` ou `linearInterp1D`).
4. Se aplicável, criar Strategy em `src/lib/modules/`.
5. Criar página em `src/pages/` consumindo o módulo.
6. Atualizar `App.tsx` com a rota.
7. Adicionar teste em `src/lib/__tests__/`.
8. Validar `npm run build` e `npm test`.
## Como retomar o trabalho
1. **Ler** `PROGRESS.md` → seção "Roadmap priorizado de melhorias"
2. **Escolher** um item (ex.: M9.1 — refinar tabelas)
3. **Implementar** seguindo o workflow acima
4. **Validar** com os 4 comandos da seção "Validação rápida"
5. **Atualizar** `PROGRESS.md` marcando o item como concluído
## Roadmap resumido (próximas iterações)
| ID | Item | Esforço | Impacto |
|----|------|---------|---------|
| **M9.1** | Refinar tabelas a partir do PDF real | 3 dias | Alto |
| **M9.2** | Cargas lineares (kN/m) por barra | 2 dias | Alto |
| **M9.3** | Screenshot 3D no PDF | 1 dia | Médio |
| **M9.4** | Export Ftool (.txt) | 2 dias | Médio |
| **M9.5** | Refatoração TypeScript (eliminar `void`) | 1 dia | Baixo |
| **M9.6** | 3D para muros/torres/pontes/barras | 3 dias | Médio |
| **M9.7** | Import JSON de projetos | 1 dia | Médio |
| **M9.8** | i18n completo (en-US) | 2 dias | Baixo |
| **M9.9** | Validação contra Blessmann | 2 dias | Alto |
| **M9.10** | Dark mode em gráficos SVG | 0.5 dia | Baixo |
| **M9.11** | Persistência em servidor (especulativo) | — | — |
| **M9.12** | Testes E2E com Playwright | 2 dias | Médio |
Detalhes completos em `PROGRESS.md`.
## Erros comuns
- `cannot find module '../bilinear-interp'` → caminho errado; arquivos em `src/lib/nbr-tables/` importam de `../bilinear-interp`, não `./`.
- Build rolldown falha → `npm install @rolldown/binding-linux-x64-gnu`.
- `oxlint permission denied` → `chmod +x node_modules/.bin/oxlint`.
- CSS variables sumindo → garantir `<ThemeProvider>` envolvendo a árvore em `App.tsx`.
- `vitest` não roda sem `vitest.config.ts` (já criado).
- Binários em `node_modules/.bin/` sem permissão → `chmod +x node_modules/.bin/<bin>`.

---
## Padrões de qualidade
- **Tipagem:** zero `as any`, zero `// @ts-ignore`
- **Estilo:** kebab-case em arquivos, PascalCase em componentes, camelCase em funções
- **Comentários:** apenas quando a matemática exige explicação
- **Tabelas:** todos os valores tipados como `readonly` com chaves literais para exaustividade
- **Testes:** ao final de cada marco, `npm run build` + `npm test` devem passar
---
## Roadmap pós-Marco 8 (Melhorias futuras)
> Para detalhes completos, estimativas e ordem sugerida, ver `PROGRESS.md`.
### 🔴 Alta prioridade

### Marco 9.5 — Refatoração TypeScript (eliminar `void` e `as unknown as`)
**Status:** ✅ Concluído (2026-07-07)
**Escopo:** Limpar padrões TypeScript fracos (`void X` para silenciar
`noUnusedLocals`, `as unknown as number[]` para escapar de checagem
de tipo) e melhorar a robustez dos módulos Strategy.
**Entregas:**
- **Eliminação de `void X`:** removidos 8 padrões `void` em 4 arquivos
(truss.ts, table-32.ts, table-24-25.ts).
- **Eliminação de `as unknown as`:** removidos 26 padrões em 13 arquivos
(table-3, 11, 12, 13, 15-17, 18-20, 23, 26, 27, modules/{truss,tower,vault}).
- **Tipagem forte em vault.ts:** substituído
`Record<string, number>` por interfaces `VaultCpeWindPerpendicular` /
`VaultCpeWindParallel` (expostos da tabela).
- **Correção de bugs latentes em interpolação:**
- `bilinear-interp.ts`: `findBracket` agora trata arrays de 1 elemento
corretamente (evita `xs[-1]` quando length=1).
- `log-interp.ts`: `findBracket` idem.
- **Flags TypeScript adicionadas:** `noImplicitOverride` em `tsconfig.app.json`.
- **Suite de testes nova:** `app/src/lib/__tests__/refactoring.test.ts`
(25 testes cobrindo cylinder, truss, tower, vault, table-32, 33, 26,
24-25, 23, 21, 22).
- **Total:** 174/174 testes passando (era 149/149).
**Padrão antes/depois:**
```ts
// Antes: silent unused + cast duvidoso
const { alphaWind, phi, aeFace, q } = input;
void input;
const grid = { xs: PHI_15 as unknown as number[], ys: [1] as readonly number[], values: [...] };
return bilinearInterp(grid, phiClamped, 1);
// Depois: tipagem explícita + nada desperdiçado
const { barType, phi, aeFace, alphaWind, q } = input;
const grid = { xs: PHI_15, ys: [1] as readonly number[], values: [...] };
return bilinearInterp(grid, phiClamped, 1);
```
**Pendências descobertas (não corrigidas neste marco):**
- `table-18-20.ts`: chaves de `T18` (0.25, 0.5, 1) não casam com `FL` (0.05, 0.1, 0.2, 0.3, 0.4).
- `table-21.ts` e `table-22.ts`: usam `f.toString()` mas `T21`/`T22` têm chaves literais como `'1/15'` — `lookup` retorna `undefined`.
- Recomendação: M9.10 ou roadmap futuro para alinhar chaves.
### Marco 9.1 — Auditoria de tabelas NBR 6123:2023
**Status:** ✅ Concluído (2026-07-07)
**Escopo:** Auditar todas as 33 tabelas + 3 anexos contra o PDF oficial
**Entregas:**
- Todos os 33 arquivos `app/src/lib/nbr-tables/table-*.ts` e `stations.ts` agora têm
cabeçalho com `Fonte: NBR 6123:2023, p. XX` e `Última auditoria: 2026-07-07`.
- **Correções aplicadas:**
- **Tabela 4 (S3):** Grupo 1 de 1,10 → **1,11** (PDF p. 15).
Grupo 2 de 1,08 → **1,06**. Adicionado `vidaUtilAnos` (100, 75, 50, 30, 2).
- **Tabela 35 (pontes):** refatorada — era função de altura z, mas a norma define
p e bₘ constantes por categoria. Corrigidos valores:
- I: 0,10 / 1,25 | II: 0,16 / 1,00 | III: 0,20 / 0,85 | IV: 0,25 / 0,68 | V: 0,35 / 0,44
- **Tabela 36 (amortecimento de pontes):** corrigidos valores discrepantes
(Madeira 6,0 → 8,0; Protensão parcial 2,0 → 2,5; Mistas 1,5 → 1,8).
- **Stations.ts (Anexo C):** altitudes corrigidas (Curitiba 510 → 910; BH 780 → 789;
Anápolis 1087 → 1097; Campinas 661 → 648) + coordenadas conferidas.
- **Suite de testes nova:** `app/src/lib/__tests__/nbr-tables.test.ts`
(43 testes cobrindo Tabelas 1, 3, 4, 5, 32, 35, 36, Anexo B e Anexo C).
- **Total:** 83/83 testes passando (era 38/38).
**Pendências (⚠️ marcadas nos arquivos):**
- Tabelas 6, 7, 8, 9, 10, 11, 12: valores simplificados no código; a norma fornece
matrizes por h/b × θ × zona que precisam ser expandidas.
- Tabela 13: chaves de indexação usam "0.5/5/25" mas a norma define apenas
"h/d=10" e "h/d≥2,5"; precisa reagrupamento.
- Tabela 14: 15+ seções × 7 razões h/ℓ × 6 Reynolds — usar valores pré-computados
por combinação específica.
- Tabelas 15–22: revisar valores numéricos por f/b e zonas (1 a 6).
- Tabela A.1, A.2: revisar valores exatos por categoria × intervalo (PDF p. 99–101).
- Tabela B.1: confirmar valores exatos da grade Pₘ × m (PDF p. 104).
- Tabela 31: revisar parâmetros γ, ξ por tipo de estrutura (PDF p. 74).
- Tabela 33: revisar Strouhal por forma da seção.
- Estações: revisar V₀ de cada uma contra Figura 1 oficial.

- Vetor de força: cilindro (haste) + cone (ponta), comprimento
proporcional a √(Fx² + Fy²) ou |F|.
- Marca amarela emissiva (#fbbf24) no ponto de aplicação.
- `gl={{ preserveDrawingBuffer: true, antialias: true }}` para
permitir captura de canvas (M9.3).
- `onCreated={({ gl }) => registerCanvas(gl.domElement)}` para
registro automático no `useCaptureStore`.
- `OrbitControls` com limites para evitar câmera underground.
#### M9.7 — Sistema de import de projetos via JSON (~1 dia)
**Status:** ✅ Concluído (ver Marco 9.7 abaixo). Roundtrip completo
testado. 29 testes novos (211/211 passando).
### Marco 9.7 — Sistema de Import de Projetos via JSON
**Status:** ✅ Concluído (2026-07-07)
**Escopo:** Permitir carregar projetos salvos em JSON de volta para
a aplicação, completando o roundtrip com o export existente.
**Entregas:**
- `app/src/lib/import-project.ts` — 14 funções exportadas:
- `parseProjectJson(text)` — parsing seguro com mensagens claras
- `detectFormat(parsed)` — detecta `SavedProject` vs `snapshot`
- `validateSavedProject(raw)` / `validateSnapshot(raw)` — validação
separada de erros fatais e warnings não-fatais
- `applySavedProject(project)` / `applySnapshot(snapshot)` —
aplicação idempotente nos stores Zustand (windStore, galpaoStore)
- `importProjectFromText(text)` — orquestrador (parse + detect + validate + apply)
- `readProjectFile(file)` — wrapper FileReader → Promise<string>
- `exportProjectToJson(project)` / `snapshotWindStoreToJson()` — roundtrip
- Tipo `ImportResult` com `ok`, `module`, `projectName`, `appliedFields`,
`warnings`, `error`
- `app/src/pages/SettingsModule.tsx` — botão "Importar projeto" ao lado
do "Exportar estado". Aceita `.json`. Mostra feedback inline com:
- ✅ Sucesso: módulo aplicado, lista de campos
- ⚠️ Avisos: validações não-fatais
- ❌ Erro: mensagem formatada (JSON inválido, formato desconhecido, etc.)
- `app/src/lib/hooks/useProjects.ts` — sem mudança (importação é via
sistema de arquivos, não IndexedDB).
- **Suite de testes nova:** `app/src/lib/__tests__/import-project.test.ts`
(29 testes cobrindo parsing, detecção, validação, aplicação e roundtrip).
- **Total:** 211/211 testes passando (era 182/182).
**Formatos suportados:**
```jsonc
// Formato 1 — SavedProject (gerado pelo export IndexedDB)
{
"name": "Galpão Teste",
"module": "galpao",
"inputs": { "wind": {...}, "galpao": {...} },
"createdAt": 1234567890,
"updatedAt": 1234567899
}
// Formato 2 — Snapshot do windStore (gerado por "Exportar estado")
{
"v0": 40, "s1": 1, "s3": 1,
"terrainCategory": "II", "s3Group": 3,
"largestDimension": 30, "heightZ": 10,
"s2": 1.06, "vk": 42.4, "q": 1.1024,
"structureClass": "B"
}
```
**Validação:**
- Erros fatais: campos obrigatórios ausentes, tipos errados, valores
inválidos (ex.: categoria fora de I–V)
- Warnings: campos opcionais ausentes (gerados automaticamente)
**Aplicação idempotente:**
- Cada campo só é aplicado se o tipo bater (number/string/boolean)
- Categoria validada contra enum antes de chamar setTerrainCategory
- Warnings não bloqueiam a aplicação dos demais campos
### 🟢 Baixa prioridade (features adicionais)
#### M9.8 — i18n completo (~2 dias)
**Status:** ✅ Concluído (ver Marco 9.8 abaixo). 130+ chaves no dicionário,
LanguageSwitcher no sidebar, hook useI18n, persistência localStorage.
39 testes novos (250/250 passando).
### Marco 9.8 — i18n completo (pt-BR + en-US)
**Status:** ✅ Concluído (2026-07-07)
**Escopo:** Expandir o sistema de i18n mínimo (~15 strings) para
cobrir toda a UI do VentoApp em pt-BR e en-US, com switcher de
idioma e persistência local.
**Entregas:**
- `app/src/lib/i18n.ts` — Expandido para **130+ chaves** organizadas
por área (nav_*, app_*, common_*, settings_*, linear_loads_*, etc.).
Mantém API pública `t(key, locale, params?)` com interpolação
`{placeholder}` e fallback automático.
- `app/src/lib/i18n.ts` (novo): funções utilitárias
- `loadStoredLocale()` / `saveStoredLocale(locale)` — persistência
- `detectBrowserLocale()` — fallback para `navigator.language`
- `listKeys()` — debug/inspeção
- `app/src/store/i18nStore.ts` — Zustand store com persistência.
Hook `useI18n()` retorna `{ t, locale, setLocale }`.
Função `tNow(key)` para tradução fora de componentes.
- `app/src/components/LanguageSwitcher.tsx` — Seletor compacto
com ícone de globo (🇧🇷 pt-BR / 🇺🇸 en-US), integrado no
rodapé do sidebar (desktop) e no header (mobile).
- Páginas migradas:
- `App.tsx` — sidebar, navegação (11 itens), HomeMock (header + cards)
- `SettingsModule.tsx` — Aparência, Projetos Salvos, Estado Atual, Sobre
- `LinearLoadsTable.tsx` — 3 abas + 4 pilares + 6 terças + reações
- `ExportMenu.tsx` — tooltips dos botões
- **Suite de testes nova:** `app/src/lib/__tests__/i18n.test.ts`
(39 testes cobrindo dicionário, interpolação, persistência,
detecção browser, componentes).
- **Total:** 250/250 testes passando (era 211/211).
**Convenção de chaves:**
```ts
// snake_case agrupadas por área
nav_home, nav_warehouse, nav_cylinder, ...
settings_appearance, settings_projects, ...
linear_loads_title, linear_loads_pillar_windward, ...
scene_capture_format, ftool_title, ...
```
**Interpolação:**
```ts
t('settings_projects_count', 'pt-BR', { count: 5 })
// → "5 projeto(s) armazenado(s)."
```
**Persistência:**
- Chave localStorage: `ventoapp.locale`
- Valor: `'pt-BR' | 'en-US'`
- Fallback: `navigator.language` → `'pt-BR'`
- Falha silenciosa se localStorage indisponível (modo privado)
#### M9.9 — Validação contra exemplos do Blessmann (~2 dias)
**Status:** ✅ Concluído (ver Marco 9.9 abaixo). 10 casos documentados,
48 testes criados (298/298 passando).
### Marco 9.9 — Validação cruzada contra Blessmann
**Status:** ✅ Concluído (2026-07-07)
**Escopo:** Criar suite de validação que compara os cálculos do VentoApp
com casos resolvidos do livro "O Vento na Engenharia Estrutural"
(J. Blessmann, EDUFRGS, 2ª ed.) e com valores tabelados da norma.
**Entregas:**
- `app/src/lib/blessmann-cases.ts` — **10 casos clássicos** documentados:
| # | Caso | Fonte |
|---|------|-------|
| 1 | Galpão 30×15×6 m, telhado duas águas | Blessmann Cap. 5 Ex. 5.1 |
| 2 | Edifício alto 60×20×100 m, Cat. III | Blessmann Cap. 9 |
| 3 | Silo cilíndrico d=8, h=24, liso, topo aberto | Tab. 13 |
| 4 | S₂ em diferentes (h, categoria, classe) | NBR 6123:2023 Tab. 3 |
| 5 | S₃ analítico (Anexo B) | NBR 6123:2023 Anexo B |
| 6 | Ponte 120 m, Pse | NBR 6123:2023 sec. 11.2.2 |
| 7 | Cobertura isolada (limites) | NBR 6123:2023 sec. 7.2.1 |
| 8 | Chaminé d=1,5, h=30, liso | Tab. 13 |
| 9 | Placa de publicidade 6×2 m | Tab. 23 |
| 10 | S₂ fórmula teórica vs Tab. 3 | NBR 6123:2023 Tab. 1 + Tab. 3 |
- Cada caso exporta: `id`, `description`, `source`, `tolerance`, `notes?`
- Helper `isWithinTolerance(calculated, expected, tolerance)` para
comparação com tolerância percentual e absoluta (para expected=0).
- `app/src/lib/__tests__/blessmann.test.ts` — **48 testes** cobrindo:
- Casos quantitativos: S₂, S₃, Vₖ, q, Cpe, Pse
- Cross-checks: fórmula teórica vs tabela
- Propriedades: monotonicidade, consistência
- Helpers e metadados dos casos
**Discrepâncias documentadas (pendências M9.1):**
Os testes para Tab. 6, Tab. 7, Tab. 13, Tab. 23 e Tab. 24-25 usam
**placeholders estruturais** (apenas verifica que a função retorna
valores finitos em faixas plausíveis). Quando M9.1 corrigir os valores
oficiais, esses testes podem ser atualizados para validação ponto-a-ponto.
**Total:** 298/298 testes passando (era 250/250).
#### M9.10 — Tema dark mode para gráficos SVG (~0.5 dia)
**Status:** ✅ Concluído (ver Marco 9.10 abaixo). SVGs migrados para
`var(--color-*)`, módulo `svg-colors` criado, 12 testes novos (310/310).
### Marco 9.10 — Dark mode em gráficos SVG
**Status:** ✅ Concluído (2026-07-07)
**Escopo:** Migrar cores hardcoded (#6366f1, #ef4444, etc.) nos
gráficos SVG inline para variáveis CSS do tema, suportando dark mode.
**Entregas:**
- `app/src/lib/svg-colors.ts` — Módulo centralizado com 10 chaves semânticas:
- `text` = `currentColor` (herda de text-foreground)
- `muted` = `var(--color-muted-foreground)`
- `primary` / `primaryFill` (com `color-mix(... transparent)`)
- `destructive` / `destructiveFill`
- `info`, `grid`, `fgSolid`, `marker`
- Paleta `SVG_PALETTE` (5 cores para multi-série, baseadas em `--chart-1` a `--chart-5`)
- SVGs migrados em 4 páginas:
- `DynamicsModule.tsx` (2 gráficos: q(z) e ζ)
- `IsolatedRoofModule.tsx` (corte esquemático de cobertura)
- `BarSelectorModule.tsx` (barra + vetor de força, fallback)
- `BridgeModule.tsx` (ponte + pilares + vetores Cx/Cz, fallback)
- Substituições aplicadas:
- `#6366f1` (roxo) → `var(--color-primary)` ou `color-mix(in oklch, var(--color-primary) 30%, transparent)`
- `#ef4444` (vermelho) → `var(--color-destructive)`
- `#94a3b8` (cinza) → `var(--color-border)`
- `#0f172a` (preto) → `var(--color-foreground)`
- `#1e293b` (preto) → `var(--color-foreground)`
- `#3b82f6` (azul) → `var(--color-primary)`
- `#cbd5e1` (cinza claro) → `var(--color-border)` com opacity
- `#fbbf24` (amarelo) → `var(--color-accent)` (futuro)
- `app/src/lib/__tests__/svg-colors.test.ts` — 12 testes:
- Presença das chaves esperadas
- Validação de que cada cor referencia variável CSS
- Unicidade da paleta de multi-série
- Contraste semântico (primary ≠ destructive)
- **Total:** 310/310 testes passando (era 298/298).
**Padrão de uso em componentes:**
```tsx
<svg viewBox="0 0 320 200">
<line stroke="var(--color-border)" strokeWidth="1" />
<path stroke="var(--color-primary)" fill="none" />
<text fill="currentColor">label</text>
</svg>
```
**Vantagens:**
- Cores se adaptam automaticamente a `.dark` no html
- Sem duplicação de lógica de tema
- Mantém fallback OKLCH via Tailwind v4
- Acessibilidade: `currentColor` herda de `text-foreground` da página
#### M9.13 — Exportação genérica de PDF para todos os módulos restantes
**Status:** ✅ Concluído (2026-07-08)
**Escopo:** Expandir a capacidade de exportação de PDF (com captura 3D) que estava limitada ao Galpão para abranger os demais módulos (Cilindros, Abóbadas, Cúpulas, Muros, Coberturas Isoladas, Barras, Pontes, Dinâmica).
**Entregas:**
- Criação de `app/src/lib/export-generic-pdf.tsx` contendo o componente `GenericReportDocument` com template flexível capaz de receber seções dinâmicas (tabelas, grids de informações).
- Injeção das funções `handleExportPDF` em cada uma das páginas (`CylinderModule.tsx`, `VaultModule.tsx`, `DomeModule.tsx`, `SignModule.tsx`, `IsolatedRoofModule.tsx`, `BarSelectorModule.tsx`, `BridgeModule.tsx`, `DynamicsModule.tsx`).
- Refatoração de `ExportMenu.tsx` para receber callbacks customizados, permitindo a exportação de PDF com suporte à visualização 3D para qualquer módulo de engenharia suportado pela NBR 6123.
- Testes de build (`tsc -b` e `vite build`) passando com sucesso e mantendo a integridade (310/310 testes unitários sem regressões).
#### M9.11 — Persistência opcional em servidor (~especulativo)
**Problema:** Tudo é local (IndexedDB).
**Tarefa:**
- Definir estratégia (Firebase? Supabase? REST própria?)
- Criar abstração `StorageAdapter` (local ou remoto)
- Adicionar autenticação básica
#### M9.12 — Testes E2E com Playwright (~2 dias)
**Problema:** Apenas testes unitários. Falta testar fluxos completos.
**Tarefa:**
- Instalar `@playwright/test`
- Criar testes E2E para: criar projeto galpão, salvar, exportar PDF
- Integrar ao CI
---
## 📋 Convenções estabelecidas (manter)
1. **Tipagem forte**: zero `as any`, zero `// @ts-ignore`
2. **Sem comentários** exceto matemática complexa
3. **Imports absolutos**: `@/lib/...`, `@/components/...`, `@/store/...`
4. **Componentes**: PascalCase `.tsx`, kebab-case utilitários `.ts`
5. **Tabelas readonly**: `Readonly<Record<...>>` em todos os `nbr-tables/`
6. **Cpi sempre explícito**: `p = q · (Cpe − Cpi)` em todos os cálculos
7. **Strategy pattern**: cada tipo de estrutura tem um módulo em `lib/modules/`
8. **Páginas**: cada rota tem uma página em `pages/` consumindo o módulo correspondente
9. **Testes Vitest**: cobrem motor matemático, interpolações, Cpi, vizinhança, Reynolds
10. **Validação antes de merge**: `npm run build` + `npm test` devem passar
---
## 🔍 Onde encontrar coisas
### Quero adicionar uma tabela NBR
→ `app/src/lib/nbr-tables/` (criar `table-N.ts`), depois expor em `coefficients.ts` ou `modules/`
### Quero adicionar uma nova estrutura (ex.: chaminé)
→ Criar `app/src/lib/modules/<tipo>.ts` com Strategy, depois `app/src/pages/<Tipo>Module.tsx`, registrar rota em `App.tsx`
### Quero adicionar nova UI
→ Componentes em `app/src/components/`, com `cn()` para merge de classes, variantes shadcn quando existirem
### Quero adicionar testes
→ `app/src/lib/__tests__/` com `vitest` (sem jsdom necessário para cálculos puros)
### Quero debugar o cálculo
→ `app/src/lib/wind-kernel.ts` é o ponto de entrada; cada função retorna valor com `toFixed(...)` para debug
---
## 🐛 Erros conhecidos (não críticos)
1. **`@rolldown/binding-linux-x64-gnu`** precisa estar instalado (foi adicionado em Marco 1)
2. **Binários em `node_modules/.bin/`** perdem o bit de execução — usar `chmod +x` antes de chamar
3. **Vitest** sem `vitest.config.ts` separado não funciona; foi criado em Marco 8
4. **TypeScript `noUnusedLocals`** está habilitado — `void input` foi adicionado para silenciar (M9.5 deve corrigir)

## 🎯 Próximo passo sugerido
**M9.7 já está completo.** Para próximos passos, considerar:
**M9.11 — Testes E2E com Playwright** (~2 dias, médio impacto) —
instalar `@playwright/test`, criar testes para fluxos completos
(criar projeto galpão → salvar → exportar PDF), integrar ao CI.
