React Performance 🚀

React is fast, until it isn't. Let's make your React app fast.

Learn everything you need to diagnose, profile, and fix performance problems in your React application using the Browser Performance Profiler, React DevTools Profiler, and proven React optimization techniques.

Prerequisites

Install the React DevTools (Chrome (recommended), Firefox)
Experience with React and all hooks

Pre-workshop Resources

Here are some resources you can read before taking the workshop to get you up to speed on some of the tools and concepts we'll be covering:

System Requirements

git v2.18 or greater
NodeJS v20 or greater
npm v8 or greater

All of these must be available in your PATH. To verify things are set up properly, you can run this:

git --version
node --version
npm --version

If you have trouble with any of these, learn more about the PATH environment variable and how to fix it here for windows or mac/linux.

npx --yes epicshop@latest add react-performance

If you experience errors here, please open an issue with as many details as you can offer.
