  return <Input type="email" placeholder="Email" />
}

Installation

npx logic2b@latest add input

Working with an AI assistant? Copy this prompt into Claude Code, Cursor or Copilot — it carries the install steps, a no-CLI fallback and a verification checklist.

Add the "input" item from the logic2b ui registry (https://ui.logic2b.com) to this project. Follow every step and verify at the end.

## Steps

1. If the project has no `components.json` yet, set up logic2b ui first:

   ```bash
   npx logic2b@latest init
   ```

2. Install the item (the CLI resolves registry dependencies automatically):

   ```bash
   npx logic2b@latest add input
   ```

3. Install any npm dependencies the command prints.

## If the CLI is not available

Do it manually from the registry payload:

1. Fetch https://ui.logic2b.com/r/input.json.
2. Write every entry in `files[]` to its mapped project path (see below).
3. Repeat (recursively) for each name in `registryDependencies`.
4. Install every package listed in `dependencies` across those payloads.

## Registry reference

- Index of every item: https://ui.logic2b.com/r/index.json
- Item payload (full source): https://ui.logic2b.com/r/<name>.json
- Usage examples per item: https://ui.logic2b.com/r/demos/index.json → https://ui.logic2b.com/r/demos/<demo>.json
- Docs index for agents: https://ui.logic2b.com/llms.txt (full docs: https://ui.logic2b.com/llms-full.txt)
- Every docs page is Markdown when you append `.md` to its URL.

Registry file paths map to project paths like this:
- `ui/*` → `@/components/ui/*`
- `blocks/<name>/*` → `@/components/*`
- `charts/*` → `@/components/charts/*`
- `hooks/*` → `@/hooks/*`
- `lib/utils.ts` → `@/lib/utils.ts`
- `theme.css` → next to the project's Tailwind entry stylesheet

## Conventions (do not break these)

- Tailwind CSS v4 (CSS-first config; no tailwind.config.js needed) and React 19.
- All colors go through semantic tokens (`bg-primary`, `text-muted-foreground`,
  `border-border`, …). Never hardcode hex/oklch values in components.
- Dark mode is class-based: toggle `.dark` on `<html>`.
- Icons come from lucide-react.

## Verify before finishing

1. The dev server starts and the app renders without console errors.
2. TypeScript compiles (`tsc --noEmit` or the framework's check).
3. Components use the theme: a `<Button>` shows the primary token color,
   and toggling `.dark` on `<html>` switches the palette.

Copy into ui/input.tsx:

import * as React from "react"

import { cn } from "@/lib/utils"

function Input({ className, type, ...props }: React.ComponentProps<"input">) {
  return (
    <input
      type={type}
      data-slot="input"
      className={cn(
        "file:text-foreground placeholder:text-muted-foreground selection:bg-primary selection:text-primary-foreground border-input flex h-9 w-full min-w-0 rounded-md border bg-transparent px-3 py-1 text-base shadow-xs transition-[color,box-shadow] outline-none file:inline-flex file:h-7 file:border-0 file:bg-transparent file:text-sm file:font-medium disabled:pointer-events-none disabled:cursor-not-allowed disabled:opacity-50 md:text-sm",
        "focus-visible:border-ring focus-visible:ring-ring/50 focus-visible:ring-[3px]",
        "aria-invalid:ring-destructive/20 dark:aria-invalid:ring-destructive/40 aria-invalid:border-destructive",
        className
      )}
      {...props}
    />
  )
}

export { Input }

Usage

import { Input } from "@/components/ui/input"

<Input type="email" placeholder="Email" />

Supports every native input type including file. Invalid state styling via aria-invalid.

API

Input renders a native <input> and forwards every standard attribute (React.ComponentProps<"input">).

Prop	Type	Default
`type`	`string` — any native input type (`text`, `email`, `file`, …)	`text`
`disabled`	`boolean`	`false`
`aria-invalid`	`boolean` — applies the destructive ring/border	—
`placeholder`	`string`	—
`className`	`string`	—

Examples

File

Picture

import { Input } from "@/components/ui/input"
import { Label } from "@/components/ui/label"

export default function InputFileDemo() {
  return (
    <div className="grid w-full max-w-sm items-center gap-3">
      <Label htmlFor="input-file">Picture</Label>
      <Input id="input-file" type="file" />
    </div>
  )
}

Disabled

import { Input } from "@/components/ui/input"

export default function InputDisabledDemo() {
  return <Input disabled type="email" placeholder="Email" />
}

Invalid

import { Input } from "@/components/ui/input"
import { Label } from "@/components/ui/label"

export default function InputInvalidDemo() {
  return (
    <div className="grid w-full max-w-sm items-center gap-3">
      <Label htmlFor="input-invalid">Email</Label>
      <Input
        id="input-invalid"
        type="email"
        aria-invalid
        defaultValue="not-an-email"
