I need to be able to parse my heap snapshots with minified code

[dolezel]

When I get heap snapshot from production, there is not way how to get original names of the objects.
Also if I take heap Allocation instrumentation on timeline / Allocation sampling, the function names in Allocation stack are minified, pointing to minified source file, but no way how to get info about the function in original code.

Thanks for reaching out. We added a feature recently to the Performance tool that allows users to unminify perf profiles recorded in production. It seems like it would be useful for you if we added a similar feature to the Memory tool now.

@joselea might have some interesting thoughts on this.

This is possible when you have sourcemaps set up, there was a write-up in the What's new in Edge 99 and the documentation is here.

@codepo8 I think @dolezel is talking about Memory heap snapshots, not the Performance profiles.

I think this is a reasonable request, maybe we can re-use the infrastructure from the performance panel here.

Thanks Jose. I'll add this to the team backlog so this can be prioritized.

Thank you guys for looking into this!
