Depends on the role - front-end, back-end, full-stack, etc... that being said, the main thing I want to see is that you're passionate about your work. If you're applying for a full-stack position, you could have one project that you iterated on over 3/6/12 months, changed technologies, refactored, and ultimately built/released something. Also, as simple as it may sound, a meaningful commit message and git history is useful too. I don't want developers that `git commit -m "Updated stuff."`
Open source contributions to relatively established projects are always good too. That indicates that you've gone through a robust review process in most cases and have written some code that most likely had a good amount of eyes on it.
