Readme
@react-grab/opencode
OpenCode agent provider for React Grab. Requires running a local server that interfaces with the OpenCode CLI.
Installation
npm install @react-grab/opencode
# or
pnpm add @react-grab/opencode
# or
bun add @react-grab/opencode
# or
yarn add @react-grab/opencodeServer Setup
The server runs on port 6567 by default.
Quick Start (CLI)
Start the server in the background before running your dev server:
npx @react-grab/opencode@latest && pnpm run devThe 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:
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
// vite.config.ts
import { startServer } from "@react-grab/opencode/server";
if (process.env.NODE_ENV === "development") {
startServer();
}Next.js
// next.config.ts
import { startServer } from "@react-grab/opencode/server";
if (process.env.NODE_ENV === "development") {
startServer();
}Note: You must have OpenCode installed (
npm i -g opencode-ai@latest).
Client Usage
Script Tag
<script src="//unpkg.com/react-grab/dist/index.global.js"></script>
<script src="//unpkg.com/@react-grab/opencode/dist/client.global.js"></script>Next.js
Using the Script component in your app/layout.tsx:
import Script from "next/script";
export default function RootLayout({ children }) {
return (
<html>
<head>
{process.env.NODE_ENV === "development" && (
<>
<Script
src="//unpkg.com/react-grab/dist/index.global.js"
strategy="beforeInteractive"
/>
<Script
src="//unpkg.com/@react-grab/opencode/dist/client.global.js"
strategy="lazyOnload"
/>
</>
)}
</head>
<body>{children}</body>
</html>
);
}ES Module
import { attachAgent } from "@react-grab/opencode/client";
attachAgent();Options
You can configure the OpenCode agent provider:
import { createOpenCodeAgentProvider } from "@react-grab/opencode/client";
const provider = createOpenCodeAgentProvider({
serverUrl: "http://localhost:6567", // Custom server URL
getOptions: () => ({
model: "claude-sonnet-4-20250514", // AI model to use
agent: "build", // Agent type: "build" or "plan"
directory: "/path/to/project", // Project directory
}),
});How It Works

Client Server Agent- React Grab sends the selected element context to the server via HTTP POST
- Server receives the request and spawns the
opencodeCLI process - OpenCode processes the request and streams JSON responses to stdout
- Server relays status updates to the client via Server-Sent Events (SSE)
