React DevTools Extension

Install the official extension in Chrome/Edge/Firefox. Open your Vite app, look for the React icon. Production minified builds show less. It’s not a VS Code-only thing — it’s in the browser.

React DevTools Extension — output — install + open the app. Production builds may hide extra data.

Exam tip

Browser extension, not only facebook.com.

Example

// Extension
console.log("Chrome/Edge/Firefox: React Developer Tools");
console.log("Open localhost:5173 → Components icon");

React DevTools Extension — output: install + open the app. Production builds may hide extra data.

Short notes

DefInstall : browser extension.
RuleOpen : localhost app.
RememberProd : less detail.
