Installation

npx logic2b@latest add input-otp

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-otp" 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-otp
   ```

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-otp.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.

Install the dependencies:

npm install input-otp lucide-react

Copy into ui/input-otp.tsx:

"use client"

import * as React from "react"
import { OTPInput, OTPInputContext } from "input-otp"
import { MinusIcon } from "lucide-react"

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

function InputOTP({
  className,
  containerClassName,
  ...props
}: React.ComponentProps<typeof OTPInput>) {
  return (
    <OTPInput
      data-slot="input-otp"
      containerClassName={cn(
        "flex items-center gap-2 has-disabled:opacity-50",
        containerClassName
      )}
      className={cn("disabled:cursor-not-allowed", className)}
      {...props}
    />
  )
}

function InputOTPGroup({ className, ...props }: React.ComponentProps<"div">) {
  return (
    <div
      data-slot="input-otp-group"
      className={cn("flex items-center", className)}
      {...props}
    />
  )
}

function InputOTPSlot({
  index,
  className,
  ...props

  index: number
}) {
  const inputOTPContext = React.useContext(OTPInputContext)
  const { char, hasFakeCaret, isActive } = inputOTPContext?.slots[index] ?? {}

  return (
    <div
      data-slot="input-otp-slot"
      data-active={isActive}

        className

      {char}
      {hasFakeCaret && (

  return (
    <div data-slot="input-otp-separator" role="separator" {...props}>
      <MinusIcon />
    </div>
  )

export { InputOTP, InputOTPGroup, InputOTPSlot, InputOTPSeparator }

Usage

import {
  InputOTP,

<InputOTP maxLength={6}>
  <InputOTPGroup>
    <InputOTPSlot index={0} />
    <InputOTPSlot index={1} />
    <InputOTPSlot index={2} />

</InputOTP>

Built on input-otp.

API

Prop	Type	Default
`maxLength` (InputOTP)	`number`	—
`value` / `onChange` (InputOTP)	`string` / `(value: string) => void`	—
`pattern` (InputOTP)	`string` — regex allow-list (e.g. `REGEXP_ONLY_DIGITS`)	—
`onComplete` (InputOTP)	`(value: string) => void` — fired when all slots fill	—
`disabled` (InputOTP)	`boolean`	`false`
`index` (InputOTPSlot)	`number` — which slot to render	—

Examples

Digits Only

Pass a pattern to restrict input — REGEXP_ONLY_DIGITS is re-exported by input-otp.

import { REGEXP_ONLY_DIGITS } from "input-otp"

import { InputOTP, InputOTPGroup, InputOTPSlot } from "@/components/ui/input-otp"

export default function InputOTPPatternDemo() {
  return (
    <InputOTP maxLength={6} pattern={REGEXP_ONLY_DIGITS}>
      <InputOTPGroup>
        <InputOTPSlot index={0} />
        <InputOTPSlot index={1} />
        <InputOTPSlot index={2} />
        <InputOTPSlot index={3} />
        <InputOTPSlot index={4} />
        <InputOTPSlot index={5} />
      </InputOTPGroup>
    </InputOTP>
  )
}

Controlled

Enter your PIN

"use client"

import * as React from "react"

import { InputOTP, InputOTPGroup, InputOTPSlot } from "@/components/ui/input-otp"

export default function InputOTPControlledDemo() {
  const [value, setValue] = React.useState("")

  return (
    <div className="flex flex-col items-center gap-2">
      <InputOTP maxLength={4} value={value} onChange={setValue}>
        <InputOTPGroup>
          <InputOTPSlot index={0} />
          <InputOTPSlot index={1} />
          <InputOTPSlot index={2} />
          <InputOTPSlot index={3} />
        </InputOTPGroup>
      </InputOTP>
      <div className="text-muted-foreground text-sm">
        {value === "" ? "Enter your PIN" : `You entered: ${value}`}
      </div>
    </div>
  )
}

Accessibility

Renders a single real <input> behind the slots, so browser and password manager autofill of one-time codes (autocomplete="one-time-code") works and the field is announced normally by screen readers.
Fully keyboard operable: typing advances through slots, Backspace moves back, and arrow keys plus paste are handled by the underlying input-otp primitive.
Invalid state is driven by aria-invalid, which styles the active slot with the destructive ring.
