I'm not sure if this is the _main_ reason, but one thing that makes node_modules size more than an aesthetic concern is serverless.

Booting a serverless function with 100s of mbs of modules takes an appreciable time - to the point where some folks webpack bundle their serverless code

Are people actually downloading dependencies on the fly like this? IMO a bundler is absolutely essential. What if npm is down? What if the version of a dependency has been deleted for some reason? These are surprises you absolutely do not want when a function is starting.

You don’t download the modules when your function starts. You include 500mb of dependencies in your 50kb lambda function.

The difference in boot time between 50kb and 500mb is quite significant.

Or left-pad or that other one. JS ecosystem seems dangerous to no version pin, pack and maybe self-host the needed+known-good modules

Is this a thing? A buddy started at a new place and he was noticing webpack bundling for the backend.

Makes sense when you think about it I guess. Only used bundlers for front end stuff.

If backend services are written in TS (instead of JS) then you'll need to compile to run it. Be that TSC or webpack with ts-loader, you'll need something to perform that step. I don't think anyone is running ts-node outside of local dev environments.

If you want typescript on the BE then you at least need a build step.

I'm just now finding that webpack is mostly a foreign concept in backend nodejs tech, but it's mind boggling to me that the norm was to ship code with the node_modules folder instead of bundling and minifying. Seriously, why? It's so wasteful... :'(

I just bundle everything except binary dependencies. Faster deployments
