The article details an innovative debugging technique for Electron apps with Rust backends via FFI. The author faced UI freezes with no visibility into native calls, so they built a proxy server to intercept and stream FFI calls into Chrome DevTools' Network tab. This approach provides real-time observability into otherwise opaque native operations, enabling effective debugging of performance issues.
Background
Electron apps often combine JavaScript frontends with native backends via FFI, but debugging these native calls can be challenging as they don't appear in standard browser devtools. Developers need specialized techniques to gain visibility into performance bottlenecks and errors in native code execution.
