Is it acceptable to have a single file with over 1000 lines of code?
Asked by

I'm currently working on a large project with extensive features, but I've noticed that some files have exceeded 1000 lines of code. I'm concerned about whether this could negatively impact web performance. Is it generally okay for major projects to have files that long, or should I consider breaking them up?

The length of a file won't directly affect the speed of your application, especially when everything is minified in production. However, a large file can slow you down while coding and understanding the logic behind it. If you're reaching 1000 lines in a single function or class, it's usually a sign that it might be doing too much. Consider breaking it up for clarity and organization.

There's really no hard and fast rule here. While having a file with 1000 lines won't slow down your app's performance, it can definitely make things harder to maintain. If you find that you're hitting that mark, it might be a good idea to ask yourself why it got so long. Often, breaking it down into smaller, more manageable files is a way to go. It makes maintenance and understanding the code a lot easier in the long run.
TechBuff93: I agree! Managing a massive file is often more challenging than having several smaller ones. But sometimes you gotta find that balance—50 files with just 2 lines each could be just as chaotic.

FrontEndDude: Thanks for that, I’m working on a spam management page that’s getting bloated. Using Next.js and TypeScript means I've got a lot of types and regex logic. Any tips on cleaning it up?
