Do you have integration tests to ensure your applications do all the things it claims to do and that dependencies don't break those things? If dependency health isn't a part of your product testing bad things can happen.

Another thing to consider is that maybe you might not need a given dependency. Sometimes it is faster to include a bunch of dependencies at the beginning of a project just to produce something functional in the shortest time. As a product matures there is a lot of opportunity to clean up the code and slowly refactor the code to not need certain dependencies.

I’ve found just the opposite especially going into companies with less mature engineers and “architects” who’ve been at the company forever and haven’t had much outside experience. They both tend to reinvent the wheel badly and write code for cross cutting concerns that have already been solved better like custom authentication and custom logging.

Then again, I’m a big proponent of avoiding “undifferentiated heavy lifting” at every layer of the stack.

I think this comes down to reinventing the wheel. I frequently see less mature developers misuse that term to avoid writing code or making architectural decisions. That term isn't an excuse to off load your work onto someone else's reinvented wheel. The idea is to avoid unnecessary churn, whether that means you writing original code or using a dependency, and even still the concept is not always the best course of action.

As an example using a framework to avoid touching the DOM is an external reinvented wheel. As a leaky abstraction the need for that framework may dissolve over time as requirements evolve. That evolution of change can result in refactoring or a growth of complexity. Accounting for those changes means reinventing the same wheels whether or not the abstraction is in place. That is because a framework serves as an architecture in a box, but if you are later making architectural decisions anyways you have out grown at least some of the framework's value.

I’ve seen it before where “I don’t need a framework”. Then after the project grows, the “architect” ends up reinventing the same framework badly. I have no problem with opinionated frameworks especially with larger organizations. It also makes it easier to onboard developers. As a new dev on a team, I’d much rather come into a company that uses Serilog than used AcmeSpecialSnowflakeLogManager.

I have seen that as well. Many people will complain that if you don't use a framework you will end up writing one anyways, which is completely false. For many people who have never worked without frameworks writing original code means inventing a new framework, because that framework-like organization is how they define programming to themselves. This behavior is safely described as naive, or a lack of exposure to differentiating methodologies. This reminds me of that quote: when you're a hammer everything looks like a nail.

So what is your definition of an agreed upon method that an organization uses to produce results....

[austincheney]

Depends on the goals and constraints of the organization.

Dependencies should be tested, yes. But I enjoy this sentence in top comment: > "extensive" unit testing is a poor man's type checker
