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.

The chrome extension was working fine and I have no errors in my React.js app in my visual studio code terminal. But now when I go to refresh my webpage, I get the error "Loading React Element Tree... If this seems stuck, please follow the troubleshooting instructions." I have read many solutions, but none seem to work for me. Has anyone experienced this issue before and been able to solve it. Solutions I have tried: updated chrome version remove react dev tools extension and reinstall it restarted computer restored to defaults on my inspect tools
useless
Angular and Vue don't need an extension because their frameworks actually work with the native chrome inspector tools. Meanwhile, the developers of React, couldnt make their framework work for the native inspector tools so instead of fixing this, they had the idea to make a work-around which is this extension. If the people who made React developed web applications before in their lives, they would have quickly come to the conclusion that React should work with the native inspector tools and that this extension is a 'band-aid' solution. Instead, this lackluster extension was made which doesnt even allow me to properly edit styles in the inspector. That stacked with some React elements not being able to support native css directive classes, like angular & vue, make React a spectacular example of how React is objectively an inferior framework to Vue and Angular. To the React developers, start over with this framework. When you can't decide if you want a component to be a class or a const, a normal component, or an FC component, so you instead try to support all of them at once, you have fundamentally failed at providing any sort of `frame` to work off of. Decide how you want a component to look like and stick with that. I recommend you look at Angular or better Vue to see how simple a component should be, and go from there. Aug 2023 update: The extension has now ceased to work all together. Selection of Dom elements or seeing them in the browser is now completely broken. It's absolutely baffling that React is the most used frontend framework, when it was developed by people with little to no experience in actual frontend framework development. To answer the person who responded: If you inspect a dom element with angular or react by right clicking it and 'Inspecting' you can see the actual custom dom elements that are in your code (<custom-element />) with the inspector tool that chrome provides. Reacts DOM in that same inspector is a jumbled mess, which is why they made this extension to make elements and components actually inspectable. Unfortunately the developers were a little lazy and the extension has a fraction of the inspection capabilities that chrome's natural inspector already has.
thx
I never use this extension and want to disable it from my project. But when I remove it, I get an annoying console message. When I disable the react devtools global hook (to disable the console log message) I get another console message telling me that my fast refresh is now disabled.
Dommage que cette extension déclenche des alertes dans la console et notamment concernant les performances..
Funcionaba genial, la última actualización de chrome lo rompió. Esto lo puse en 2022, es increible que no lo hayan actualizado, no se puede testear en el browers más usado del mundo. En el único lugar donde funciona esta extensión es en firefox
Era muy util hasta que dejo de funcionar. Corregirlo por favor!
Во избежание серьезных проблем не рекомендую использовать
Since last update stopped working in Chrome v.100.
