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.

It's strange that the latest version works in vue pages (third-party's or mine), never happened before. Because of the tsx? 有点奇怪,它的新版本会在第三方或者我的vue页面中检测到react并运行,之前没有的,是因为我用了tsx?

If you are developing using this, PLEASE NOTE, it will highly use CPU and memory when on a React website. This can cause other tabs to freeze, notably YouTube: YouTube will freeze when on React websites. This doesn't just happen on websites you are working on, if you go on Scratch (the only example I can think of at the moment), YouTube will freeze as Scratch is made with React today. This caused me to think I was programming badly, losing me weeks of progress, trying to fix the problem when in reality, it's this extension which is the problem. I'd rate it 0 due to this but it does help with development, it's not a necessity in my eyes but it can help a fair amount. Besides from that, it does sometimes just fail to detect React websites, causing you to refresh lots when you need to view something on it. One of the most interesting aspects of it is that it tells you when a website uses React, which can be cool to see, some unexpected sites too... BBC Bitesize.

I don't get why Profiler needs ReactDOM 18+ when it hasn't been released as stable yet

It says 'This page doesn’t appear to be using React.' in my REACT APP and I allowed access to file URLs as it's shown on github. doesn't work.

Is it just me or is this extension lately showing incorrect status for websites that're made with React.js? For instance lately it's showing YouTube as This page is using the production build of React. ✅. Also does the same for my university website that hasn't change since a long time but recently this extension shows the same message for my university's website!
