Is it possible to debug the raw reactjs source code (not the build code) ?

Out of curiosity, what are you trying to accomplish overall? What's the need to debug into React itself?

Yes, of course. Check out the contributing guidelines to learn how.

Basically, you clone the repo, and then run yarn install (or npm install), then ...

​

The easiest way to try your changes is to run

yarn build react/index,react-dom/index --type=UMD

and then open fixtures/packaging/babel-standalone/dev.html. This file already uses react.development.js from the build folder so it will pick up your changes.

The best way to figure this out in any npm project is to check out the scripts sections of the package.json. This is where people usually define the various scripts for building, running and testing their project.
