Hey Subha!
Mostly, recruiters aren't going to look at your code or think too deeply about it.
I would just make sure your code is in the language of the job you're applying for, and is ideally in the framework (for instance, React or Vue).
Put it in the README so the recruiter can obviously tell what framework it is.
However, my MAIN TIP for side projects is this:
Get someone to review your side project's code.
It will help the quality and set you apart from other candidates.
Bonus tip: Have some tests. Extra bonus if they are good tests.
Again, both of those things will really set your code apart, assuming that a hiring manager looks at it. They may or may not -- depends heavily on how recruitment works at the company.
Good luck, Subha!
