Grab


Select context for coding agents directly from your website
How? Point at any element and press ⌘C (Mac) or Ctrl+C (Windows/Linux) to copy the file name, React component, and HTML source code.
It makes tools like Cursor, Claude Code, Copilot run up to 3× faster and more accurate.
Run this command to install React Grab into your project. Ensure you are running at project root (e.g. where the next.config.ts or vite.config.ts file is located).
``html`
npx -y grab@latest init
Once installed, hover over any UI element in your browser and press:
- ⌘C (Cmd+C) on Mac
- Ctrl+C on Windows/Linux
This copies the element's context (file name, React component, and HTML source code) to your clipboard ready to paste into your coding agent. For example:
`js`
Forgot your password?
in LoginForm at components/login-form.tsx:46:19
If you're using a React framework or build tool, view instructions below:
#### Next.js (App router)
Add this inside of your app/layout.tsx:
`jsx
import Script from "next/script";
export default function RootLayout({ children }) {
return (
#### Next.js (Pages router)
Add this into your
pages/_document.tsx:`jsx
import { Html, Head, Main, NextScript } from "next/document";export default function Document() {
return (
{/ put this in the /}
{process.env.NODE_ENV === "development" && (
src="//unpkg.com/grab/dist/index.global.js"
crossOrigin="anonymous"
strategy="beforeInteractive"
/>
)}
);
}
`#### Vite
Your
index.html could look like this:`html
`#### Webpack
First, install React Grab:
`bash
npm install grab
`Then add this at the top of your main entry file (e.g.,
src/index.tsx or src/main.tsx):`tsx
if (process.env.NODE_ENV === "development") {
import("grab");
}
`Extending React Grab
React Grab exposes the
__REACT_GRAB__ API for extending functionality with plugins, hooks, actions, themes, and custom agents.packages/react-grab/src/types.ts and packages/react-grab/src/core/plugin-registry.ts for reference.Or copy this into an agent to generate a plugin:
`md
Clone https://github.com/aidenybai/react-grab into /tmpCheck these files for reference:
- packages/react-grab/src/types.ts (Plugin and PluginHooks interfaces)
- packages/react-grab/src/core/plugin-registry.ts (implementation)
Plugins are registered via
__REACT_GRAB__.registerPlugin({ name, hooks, actions, theme }).Add the code in client-side code (e.g., "use client" in Next.js) inside a useEffect after React Grab loads.
Generate an example plugin that logs when an element is selected.
