I’ve been writing all my side projects without dependencies or only with ones that have no dependencies themselves if I need to do a proof-of-concept or idea and don’t want to write out the whole thing. It’s been so so educating, so fun, I learned a million things. Why companies overwhelmingly choose and allow to rely on 3rd party source code, that needs its own lifecycle support, especially for own domain logic, is not clear to me at all. Sure some specialist tooling is high quality and you should then contribute to it (if it’s in your critical path), but the advantage that is lost by not betting on the platform and properly learning it is huge.
