Came across this thread just now. Interesting that source maps had a big performance impact and that there’s an open issue in the V8 engine about it. Anyone using this instead of the --enable-source-maps flag?

I use this plugin because when i set the flag to true in serverless it doesnt work

We're likely going to build this into sst. This reflects the same research I did

So I was originally using

node-source-map-support

and swapped over to the

NODE_OPTIONS

I thought we were messing with something and found this wasn't as big of a hit. Is it recommended to swap back to the registering the package myself? Or maybe just hold out until this is built in?

In my testing it's only slow when an exception is thrown (includes when it's caught)
