# Fiber Debugger
|
|
|
|
This is a debugger handy for visualizing how [Fiber](https://github.com/facebook/react/issues/6170) 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](https://twitter.com/dan_abramov).
|
|
|
|
### 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.
|
|
|
|
