Ever wondered how React Native DevTools actually work? Szymon Chmal did, and then reverse-engineered the whole thing. In this live talk at React Advanced London, he’ll reveal what he uncovered: a modular architecture, clean injection points, and just enough loopholes to make DevTools truly extensible.

You’ll learn how he went from hacking around to building a full plugin framework: no forks, no hacks, just smart architecture. From embedding React-based UIs to enabling sandboxed execution, this session will change how you see DevTools.
