Overview

Product summary

Review the store description, core capabilities, and common use cases.

React Developer Tools is a Chrome DevTools extension for the open-source React JavaScript library. It allows you to inspect the React component hierarchies in the Chrome Developer Tools.

You will get two new tabs in your Chrome DevTools: "Components ⚛" and "Profiler ⚛".

The Components tab shows you the root React components that were rendered on the page, as well as the subcomponents that they ended up rendering.

By selecting one of the components in the tree, you can inspect and edit its current props and state in the panel on the right. In the breadcrumbs you can inspect the selected component, the component that created it, the component that created that one, and so on.

If you inspect a React element on the page using the regular Elements tab, then switch over to the React tab, that element will be automatically selected in the React tree.

The Profiler tab allows you to record performance information.

Hi, So I struggled with this same issue for about 30 minutes before figuring it out. I am using the latest Chrome browser too and the latest React developer tools. **You will only see the components when you are browsing a website or page built with React technology.** So for instance, when I am on the Google homepage, I will not see React components button on my dev tools but when I am on the Facebook or React homepage or any other page build with react, I will see the Component and the Profiler buttons in dev tools. The extension button you have on your browser extension bar is just to tell you whether or not the website you are on uses react. I hope this helps. Happy coding. @AnatuGreen
