Vite Guide

As a script tag

Add the script tag to your index.html.

Refer to the CDN Guide for the available URLs.

html

<!doctype html>
<html lang="en">
  <head>
    <script src="https://unpkg.com/react-scan/dist/auto.global.js"></script>

    <!-- rest of your scripts go under -->
  </head>
  <body>
    <!-- ... -->
  </body>
</html>

As a module import

In your project entrypoint (e.g. src/index, src/main):

jsx

// src/index
import { scan } from "react-scan"; // must be imported before React and React DOM
import React from "react";

scan({
  enabled: true,
});

If you want react-scan to also run in production, use the react-scan/all-environments import path

diff

- import { scan } from "react-scan";
+ import { scan } from "react-scan/all-environments";

[!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.
