bun build source map : Exclude node modules

[Crash--]

What is the problem this feature would solve?

I used to bundle my Javascript script using bun, something like :

bun build ./src/TaskLauncherLambda.mts --outdir ./dist --target node --entry-naming TaskLauncherLambda.mjs

It works great and I just added --sourcemap="linked" to generate the source map. Works great too.

But I need to run my Javascript script with node, so I launch node with ----enable-source-maps but there are some perf issues with "big sourcemap". cf nodejs/node#41541

It seems that the user using esbuild are happy with the perf when excluding the node_modules from the source map. cf evanw/esbuild#1685 (comment)

What is the feature you are proposing to solve the problem?

I'm proposing a way to exclude the node_modules from the source map.

What alternatives have you considered?
