# @react-grab/claude-code
Claude Code agent provider for React Grab. Requires running a local server that interfaces with the Claude Agent SDK.
## Installation
```bash
npm install @react-grab/claude-code
# or
pnpm add @react-grab/claude-code
# or
bun add @react-grab/claude-code
# or
yarn add @react-grab/claude-code
```
## Server Setup
The server runs on port `4567` by default.
### Quick Start (CLI)
Start the server in the background before running your dev server:
```bash
npx @react-grab/claude-code@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"
```
### Recommended: Config File (Automatic Lifecycle)
For better lifecycle management, start the server from your config file. This ensures the server stops when your dev server stops:
### Vite
```ts
// vite.config.ts
import { startServer } from "@react-grab/claude-code/server";
if (process.env.NODE_ENV === "development") {
startServer();
}
```
### Next.js
```ts
// next.config.ts
import { startServer } from "@react-grab/claude-code/server";
if (process.env.NODE_ENV === "development") {
startServer();
}
```
## Client Usage
### Script Tag
```html
```
### Next.js
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" && (
<>
)}
{children}
);
}
```
### ES Module
```tsx
import { attachAgent } from "@react-grab/claude-code/client";
attachAgent();
```
## How It Works

Client Server Agent
```
1. **React Grab** sends the selected element context to the server via HTTP POST
2. **Server** receives the request and forwards it to Claude Code via the Agent SDK
3. **Claude Code** processes the request and streams responses back
4. **Server** relays status updates to the client via Server-Sent Events (SSE)
