The problem would be the dependencies of your dependencies, and keep going many levels.

The problem is that node.js doesn't have a good standard library so one must rely on external packages to build even basic apps.

But presumably, you only include dependencies that you trust and those dependencies themselves do their trusting more strictly than you. Trust is built on vetting, signatures and reputation.

That is, at least what we do, in theory. In practice, we cross fingers and let the LLM pick dependencies, are satisfied if it just works and we either update our deps frequently or infrequently.
