# 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.

## Current Project Context

```json
!`npx shadcn@latest info --json`
```

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 follows the project base.** Use `toast` from the `toast` component for
  Base UI projects. Use `toast()` from `sonner` for Radix and React Aria
  projects.
- **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.

### Chat & Messaging → [chat.md](./rules/chat.md)

- **Chat UI composes the chat primitives.** Conversations use `MessageScroller`, rows use `Message`, surfaces use `Bubble`. Never hand-rolled bubble `div`s or a raw scroll container.
- **`MessageScroller` owns scroll behavior.** Streaming follow, anchoring, and jump-to-latest (`MessageScrollerButton`) are built in. Don't write a `useStickToBottom`/`ResizeObserver` hook.
- **Attachments use `Attachment`; system notes and dividers use `Marker`.** Not `Item` cards or `Separator` + a label.

### CLI

- **Never decode preset codes or build preset URLs manually.** Use `npx shadcn@latest preset decode <code>`, `preset url <code>`, or `preset open <code>`. For project-aware preset detection, use `npx shadcn@latest preset resolve`.
- **Apply preset codes directly with the CLI.** Use `npx shadcn@latest apply <code>` for existing projects, or `npx shadcn@latest init --preset <code>` when initializing.

## 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
```

## 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`).
- **`preset`** → resolved preset code and values for the current project. Use `npx shadcn@latest preset resolve --json` when you only need preset information.

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`, `owner/repo`, etc.), ask which registry to use. Never default to a registry on behalf of the user.
9. **Switching presets** — Ask the user first: **overwrite**, **partial**, **merge**, or **skip**?
   - **Inspect current preset**: `npx shadcn@latest preset resolve`. Use `--json` when you need structured values.
   - **Inspect incoming preset**: `npx shadcn@latest preset decode <code>`. Use `preset url <code>` or `preset open <code>` to share or open the preset builder.
   - **Overwrite**: `npx shadcn@latest apply <code>`. Overwrites detected components, fonts, and CSS variables.
   - **Partial**: `npx shadcn@latest apply <code> --only theme,font`. Updates only the selected preset parts without reinstalling UI components. Supported values are `theme` and `font`; comma-separated combinations are allowed. `icon` is intentionally not supported, because icon changes may require full component reinstall and transforms.
   - **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.
   - **Important**: Always run preset commands inside the user's project directory. `apply` only works in an existing project with a `components.json` file. The CLI automatically preserves the current base (`base` vs `radix`) from `components.json`. If you must use a scratch/temp directory (e.g. for `--dry-run` comparisons), pass `--base <current-base>` explicitly — preset codes do not encode the base.

## Design Systems from DESIGN.md

When the user asks for a design system from a `DESIGN.md` (or a brand spec), with or without a preset, follow [design-system.md](./design-system.md) end to end:

1. `init --preset <code> --template <vite|next> --name <app> --no-monorepo -y`. Without a preset code, pick the closest style and pass `--base base --preset <style>`. Then `add --all -y`.
2. Read the DESIGN.md frontmatter, Do's and Don'ts, and Known Gaps before editing.
3. Map its tokens onto the shadcn variables in `tailwindCssFile`. Pin the radius scale, shadows, fonts and `type-*` utilities.
4. Restyle components by editing their `cva` variants. Change control heights together.
5. Build the design system page per [design-system-page.md](./design-system-page.md): contrast-checked color roles, type specimens, pinned state matrices, edge cases, do/don't pairs, recipes. Check coverage with `scripts/showcase-coverage.mjs`.
6. Verify in a browser: typecheck, no console errors, loads at the top, no horizontal overflow, dark mode.

## 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.**

      (except as stated in this section) patent license to make, have made,
      use, offer to sell, sell, import, and otherwise transfer the Work,
      where such license applies only to those patent claims licensable
      by such Contributor that are necessarily infringed by their
      Contribution(s) alone or by combination of their Contribution(s)
      with the Work to which such Contribution(s) was submitted. If You
      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You
      meet the following conditions:

      (a) You must give any other recipients of the Work or
          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
