In your project entrypoint (e.g. src/index
, src/main
):
// src/index.jsx
// must be imported before React and React DOM
import { scan } from "react-scan";
import React from "react";
scan({
enabled: true,
});
Caution
React Scan must be imported before React (and other React renderers like React DOM) in your entire project, as it needs to hijack React DevTools before React gets to access it.
