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.
Inspect the latest comments and rating distribution.

Love being able to drill down through the react objects!
真是个好东西啊
React developer tab is always white!
It's alright, but I have a single gripe that should be easy to fix. I'm developing a larger app that has some very deep nesting, and it's an incredible pain to open each component to inspect the props and/or state; can we get a button (or just a default) completely expanded tree? Otherwise, this is fine for smaller and non-deep nested apps.
Extension 'Allow access to file urls' needs to be checked before you can use it! Also check github where this project is developed.
Very helpful tool. There are times when the tab isnt visible in my console but usually works great
Pretty useful tool! Found a bug though, if you mouse over an element and then close devtools using the keyboard shortcut, it closes the devtools window but doesn't remove the highlight around that element. Not sure if this is intentional.
It seems that you need to check "allow access to file URLs", even to get it to show up on normal (non-file) URLs
