Installation

npx logic2b@latest add sonner

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 "sonner" 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 sonner
   ```

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/sonner.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 sonner

Copy into ui/sonner.tsx:

"use client"

import * as React from "react"
import { Toaster as Sonner, type ToasterProps } from "sonner"

function Toaster({ theme = "system", ...props }: ToasterProps) {
  return (
    <Sonner
      theme={theme}
      className="toaster group"
      style={
        {
          "--normal-bg": "var(--popover)",
          "--normal-text": "var(--popover-foreground)",
          "--normal-border": "var(--border)",
        } as React.CSSProperties
      }
      {...props}
    />
  )
}

export { Toaster }

Usage

Add the Toaster component once, then call toast() from anywhere.

import { Toaster } from "@/components/ui/sonner"

<Toaster />

import { toast } from "sonner"

toast("Event has been created")

API

The Toaster component wraps sonner’s Toaster and forwards every ToasterProps. Toasts themselves are created imperatively with toast().

Prop	Type	Default
`theme`	`light \| dark \| system`	`system`
`position`	`top-left \| top-center \| top-right \| bottom-left \| bottom-center \| bottom-right`	`bottom-right`
`richColors`	`boolean`	`false`
`closeButton`	`boolean`	`false`
`expand`	`boolean`	`false`
`duration`	`number` (ms)	`4000`

Examples

With an action

import { toast } from "sonner"

import { Button } from "@/components/ui/button"
import { Toaster } from "@/components/ui/sonner"

export default function SonnerActionDemo() {
  return (
    <div>
      <Toaster />
      <Button
        variant="outline"
        onClick={() =>
          toast("Event has been created", {
            description: "Sunday, December 03, 2026 at 9:00 AM",
            action: {
              label: "Undo",
              onClick: () => toast("Event removed"),
            },
          })
        }
      >
        Show toast with action
      </Button>
    </div>
  )
}

Promise

import { toast } from "sonner"

import { Button } from "@/components/ui/button"
import { Toaster } from "@/components/ui/sonner"

export default function SonnerPromiseDemo() {
  const save = () =>
    new Promise<void>((resolve) => setTimeout(resolve, 1500))

  return (
    <div>
      <Toaster />
      <Button
        variant="outline"
        onClick={() =>
          toast.promise(save, {
            loading: "Saving changes...",
            success: "Changes saved",
            error: "Could not save changes",
          })
        }
      >
        Save changes
      </Button>
    </div>
  )
}
