@react-grab/cursor

Cursor agent provider for React Grab. Requires running a local server that interfaces with the Cursor Agent CLI.

Installation

``bash
npm install @react-grab/cursor


or

pnpm add @react-grab/cursor

or

bun add @react-grab/cursor

or

yarn add @react-grab/cursor
`

Server Setup

The server runs on port 5567 by default.

$3

Start the server in the background before running your dev server:

`bash
npx @react-grab/cursor@latest && pnpm run dev
`

The server will run as a detached background process. Note: Stopping your dev server (Ctrl+C) won't stop the React Grab server. To stop it:

`bash
pkill -f "react-grab.*server"
`

$3

For better lifecycle management, start the server from your config file. This ensures the server stops when your dev server stops:

$3

`ts
// vite.config.ts
import { startServer } from "@react-grab/cursor/server";

if (process.env.NODE_ENV === "development") {
startServer();
}
`

$3

`ts
// next.config.ts
import { startServer } from "@react-grab/cursor/server";

if (process.env.NODE_ENV === "development") {
startServer();
}
`

Client Usage

$3

`html


`

$3

Using the Script component in your app/layout.tsx:

`jsx
import Script from "next/script";

export default function RootLayout({ children }) {
return (


{process.env.NODE_ENV === "development" && (
<>
src="//unpkg.com/react-grab/dist/index.global.js"
strategy="beforeInteractive"
/>
src="//unpkg.com/@react-grab/cursor/dist/client.global.js"
strategy="lazyOnload"
/>

)}

{children}

);
}
`

$3

`tsx
import { attachAgent } from "@react-grab/cursor/client";

attachAgent();
`

How It Works

`
┌─────────────────┐ HTTP ┌─────────────────┐ stdin ┌─────────────────┐
│ │ localhost:5567 │ │ │ │
│ React Grab │ ──────────────► │ Server │ ─────────────► │ cursor-agent │

Client Server Agent
`

1. React Grab sends the selected element context to the server via HTTP POST
2. Server receives the request and spawns the cursor-agent` CLI process
3. cursor-agent processes the request and streams JSON responses to stdout
4. Server relays status updates to the client via Server-Sent Events (SSE)
