Description from store
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.
This extension requires permissions to access the page's React tree, but it does not transmit any data remotely. It is fully open source, and you can find its source code at https://github.com/facebook/react/tree/master/packages/react-devtools-extensions.

- (2025-02-02) Саша: When next-intl is enabled and an incorrect translation key is used, it triggers an infinite loop of errors, such as: IntlError: MISSING_MESSAGE: Could not resolve 'title 123' in messages for locale 'en'. React Strict Mode disabled In a regular browser session, the console gets flooded with these errors, while in incognito mode, only two messages appear
- (2025-01-29) Thaís Carvalho: What’s the deal with this required "copy and paste" permission? It states that the extension can modify any data I copy and paste. Am I missing something about why this is necessary to keep the extension enabled? Bizarre. Edit: I found more context about this in their repository if anyone is interested: https://github.com/facebook/react/pull/32077 https://github.com/facebook/react/issues/32244 https://github.com/facebook/react/pull/32262
- (2025-01-29) Jon Simão (J0N): The copy & paste access is really a madness, think about it: If you have a crypto wallet address copy and then you go to make a transfer on an exchange, they can change that wallet address to another and then you cry.. This can apply for bank transfers and every money transactions. They're crazy release something like that.
- (2025-01-29) J-Dawg: Tool just started requesting copy & paste access. Anyone have an idea why it'd need this? I'm disabling for now.

- (2024-07-31) Mohammad Moaid: the extension is sending "postMessage" to web pages unnecessarily and so frequently (every second). I wonder why? It is interfering with my extension, I hope this can be fixed in the coming release this is what is being sent when I console.log(event.data) from my injected script { "source": "react-devtools-content-script", "hello": true }
