Show HN: Wirebrowser – A JavaScript debugger with breakpoint-driven heap search

Alright fellow crafters, let's talk about a new tool that's caught our eye in the workshop – Wirebrowser. Think of it as your trusty magnifying glass for JavaScript, but with some serious horsepower. It’s not just about peeking at network requests or tweaking them on the fly, though it does that beautifully. The real magic here is how it dives deep into your code's memory. Imagine hitting a breakpoint and, instead of just pausing, Wirebrowser automatically snaps a picture of your application's memory at that exact moment. Then, it zips through that snapshot, hunting for the specific data or structure you're after. This isn't just finding a needle in a haystack; it's pinpointing precisely *when* that needle appeared and *which* function in your code was the artisan responsible for crafting it.

This breakpoint-driven heap search (BDHS) is a game-changer for understanding those tricky, emergent bugs. But Wirebrowser doesn't stop there. It also offers a "Live Object Search" that’s incredibly practical for runtime debugging. This feature lets you poke around your live objects, not just static snapshots. You can even use regular expressions to find patterns and go a step further by patching those objects directly in memory as your code runs. This means you can experiment with fixes and observe their immediate impact without a full recompile. If you've ever wrestled with complex state management or elusive memory leaks in your JavaScript projects, this tool promises a more direct and insightful approach to finding and fixing those issues, embodying that craftsman's pursuit of elegance and understanding.
