Your index.html could look like this:

`html








`bash
npm install react-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("react-grab");
}
`

Coding agent integration (beta)

React Grab can send selected element context directly to your coding agent. This enables a workflow where you select a UI element and an agent automatically makes changes to your codebase.

This means no copying and pasting - just select the element and let the agent do the rest. Learn more →

Extending React Grab

React Grab provides an public customization API. Check out the type definitions to see all available options for extending React Grab.

`typescript
import { init } from "react-grab/core";

const api = init({
theme: {
enabled: true, // disable all UI by setting to false
hue: 180, // shift colors by 180 degrees (pink → cyan/turquoise)
crosshair: {
enabled: false, // disable crosshair
},
elementLabel: {
// when hovering over an element
backgroundColor: "#000000",
textColor: "#ffffff",
},
},

onElementSelect: (element) => {
console.log("Selected:", element);
},
onCopySuccess: (elements, content) => {
console.log("Copied to clipboard:", content);
},
onStateChange: (state) => {
console.log("Active:", state.isActive);
},
});

api.activate();
api.copyElement(document.querySelector(".my-element"));
console.log(api.getState());
