Fiber Debugger

This is a debugger handy for visualizing how Fiber works internally.

It is only meant to be used by React contributors, and not by React users.

It is likely that it might get broken at some point. If it's broken, ping Dan.

Running

First, npm run build in React root repo folder.

Then npm install and npm start in this folder.

Open http://localhost:3000 in Chrome.

Features

• Edit code that uses ReactNoop renderer
• Visualize how relationships between fibers change over time
• Current tree is displayed in green
