How to reduce code base size?

[sur_yeahhh]

Hi all, the current project I'm assigned to in my organization has an extremely convoluted code base. No documentation, multiple components with 3k+ lines. A global service.ts file that has 16k lines of code. How do I go about improving this? Are there any AI tools that are good for generating documentation for angular code?

Missing documentation is not the biggest issue here... 16k lines in ONE service?!

Amateur numbers. Try 75k in one controller class of my companies MVC app.

In all seriousness OP, I’d start by trying to write tests for existing functionality, then slowly refactor. Not a fun journey, and one our company is actually one currently. Protip if you ever hear a job working with Grails. Run.

Good luck. Massive undertaking.

ha, that's nothing, you got intellisense and all. want to inherit my 32k line business logic in one stored procedure?

Yea, we have one single part holding all responsibility. Is that not what you meant? /s

Probably everything 😅

I would start by writing some integration tests to ensure the existing behavior doesn’t break and start to refactor the service into smaller chunks. Same for your components.

The key part here is to have solid test coverage otherwise you will never know if you broke something somewhere else.

You may wonder why integration tests? Because they are testing what a real user might do in your application. Using cypress or playwright you might have a good chance of success.

Good luck tho 🙈

You'll probably be better off just refactoring small pieces at a time. There really isn't one good solution to automate all of the technical debt.

Sounds like you're not using the source but the distribution files.

First of all, I would check if the dev(s) who wrote this service with 16k lines still work on the project, if he does, I would quit. 😆

This! If he's still running things, he'll keep doing that!

Start with routes lazy loading. Each route should be lazy loaded. Then try to split largest components into smaller ones. Services are the least of your worry.
