I'm currently working on webhook handlers and I've been breaking down the logic into smaller, dedicated functions to enhance maintainability, readability, and ease of testing. Now, I'm left wondering: at what point does a file become too fragmented with functions? Are there any best practices for structuring functions, particularly in small, large, or enterprise-grade codebases? Also, what should indie developers keep in mind when handling their own projects?

Don't get too hung up on the sheer number of functions in a file. Sure, if a file is massive, it might hint at underlying issues, but that's not the only gauge for code quality. Focus on what each function represents and how well it encapsulates its purpose. Organize your files around the ideas they convey, not just their size. Remember, think in terms of features and domains rather than just file structure. Check out "Domain-Driven Design" for more insights!
I see your point, but I think a large file can definitely be a red flag! Can't ignore those code smells!
Instead of worrying about 'too many' functions, consider cohesion. A good function should have a single focus. If you end up with lots of small functions, you’re likely on the right track! Check out the concept of cohesion for more info.
Thanks for that! I really like the idea of organizing by purpose!
And LOL at the 2.94MB `checker.ts` file from the TypeScript source!
