And how to debug a running game from a browser? Or you can only debug native builds?
I believe hooking up a debugger to your IDE is also possible. I haven’t tried it yet though: https://emscripten.org/docs/porting/Debugging.html?
Maybe I’ll give it a go and write about it in my next post.

...IME this is a lot easier to setup than the Chrome extension (the problem in Chrome that's easy to overlook is to allow Chrome access to your source code directory, the VSCode extension doesn't require such brittle details).
The blog post I posted in a sibling comment above details how to setup VSCode so that debugging works by just pressing F5 in VSCode like it would work for natively compiled code.

TL;DR: there's a new WASM DWARF debugging extension for VSCode which allows a 'traditional' debugging experience for WASM code running either in Node.js or Chrome.
Emscripten can generate DWARF debug info for a while now, and there are extensions for Chrome and VSCode which make use of this DWARF debug information and allow for a much better debugging experience.
E.g. see here:
