React team launched a new version of the React Dev Tools (v4) a few weeks ago and it’s fantabulous. It gives you debugging superpowers to navigate through your tree, trace data flow, spot weak links and optimise for perf.
The React DevTools is under active development, and new features are added all of the time. This article will show you five of those features that you might not have tried out yet, or that you simply didn’t know existed!
Say hello to the new perf hotness - a profiler built into React. This announcement blog post shows how to use it as a Chrome Extension, but you can also use it in your code, to get insight into real world interactions, even in production. Let's see how.
React 16.5 adds support for a new DevTools profiler plugin. This plugin uses React’s experimental Profiler API to collect timing information about each component that’s rendered in order to identify performance bottlenecks in React applications. It will be fully compatible with our upcoming time slicing and suspense features.
Nitin Tulswani is a prolific developer and the creator of react-perf-devtool, a library that helps with profiling the performance of your React components since react-addons-perf was deprecated in React 16. In this episode we discuss Nitin's approach to writing code and the motivation behind several of his open source projects.
