JavaScript Debugging
React Native DevTools
We're excited to share that React Native DevTools (the modern Chrome DevTools-based debugger) is now fully supported in React Native Windows starting 0.81!
What you can do now:
- Debug JavaScript – Set breakpoints, step through code, inspect variables
- Use the Console – View logs, evaluate JS, inspect objects
- Profile performance – CPU profiler, memory snapshots, React render timing
- Inspect React components – Browse component tree, view/edit props & state, highlight elements on device
Press "J" in Metro to launch DevTools instantly (just like Android/iOS!)
For complete documentation of capabilities: React Native DevTools
Why this matters:
Windows developers now get the same debugging experience as Android and iOS. No more second-class tooling – it's full platform parity.
Technical details:
- Works with Hermes engine on both Composition and Paper apps
- Based on stable React Native 0.76+ DevTools architecture
