Overview

A Chrome extension that helps debug React applications by memorizing the state of components with every render.

Reactime was nominated for the Productivity Booster award at React Open Source Awards 2020. Reactime is an open source Chrome developer tool for time travel debugging and performance monitoring in React applications. Reactime enables developers to record snapshots of application state, jump between and inspect state snapshots, and monitor performance metrics such as component render time and render frequency. Features: - Record Snapshots of Application State and Accessibility Tree - Import and Export Snapshots of State - Time-Travel Debugging - Snapshot Series Comparison - Component Tree Visualization - React Router Compatibility - Component Render Time & Frequency - Support for Gatsby, Next.js and Remix - TypeScript Support - Ability to Reconnect - Web Performance Metrics - Tutorial Walkthrough What’s New! Reactime v24.0 introduces new accessibility tree information saved with each snapshot, allowing users to easily inspect the information that screen readers will receive. These snapshots can be viewed in the new "Accessibility" tab. https://medium.com/@evaury/relaunching-reactime-updates-and-a-new-accessibility-feature-1f0fd3a5bd8c Troubleshooting: Why is Reactime telling me that no React application is found? Reactime initially runs using the dev tools global hook from the Chrome API. It takes time for Chrome to load this. The current workaround is to navigate to your Chrome Extensions and refresh Reactime. Then, navigate back to your application, refresh the page, and then within the Reactime Dev Tool, right-click and hit "Reload Frame". Why do I need to have React Dev Tools enabled? Reactime works in tandem with the React Developer Tools to access a React application's Fiber tree; under the hood, Reactime traverses the Fiber tree through the React Developer Tool's global hook, pulling all relevant information needed to display to the developer There is a black screen instead of the Reactime extension Try refreshing the application you want to test and refresh the DevTools by clicking the right mouse button “Reload frame”. I found a bug in Reactime Reactime is an open source project, and we'd love to hear from you about improving the user experience. Please read the DEVELOPER README in GitHub and create a pull request (or issue) to propose and collaborate on changes to Reactime. By default this only our app only injects content scripts into localhost. If you would like it to run on more websites please go to https://github.com/open-source-labs/reactime. Fork and clone the repository and change "matches": ["http://localhost/*"] to "matches": ["<all_urls>"] in the manifest.json src\extension\build\manifest.json

Useful tool but on the latest update it shows a random number on the browser tabs which is very annoying.
