Why not just debug on component creation? Or maybe on DOM subtree modification [0]? Or maybe modify the compiled JS to add log or trace statements?

It’s all in your browser. You have a debugger at your fingertips.

Why doesn’t Vue stop this from happening? Because it assumes whatever you’re telling it to do is what you want it to do.

iirc Chrome sometimes handles stack-overflows and/or out of memory conditions badly. If you have any function there that is called try making an entry/exit counter and log/throw if it goes above some threshold.

Maybe try console logging?
