I Published My First npm Package — Here's Everything I Wish I Knew

Publishing to npm isn't hard. But the details trip everyone up. Here's the complete guide.

Why Publish to npm?

Reusability — Use your own code across projects without copy-paste

Credibility — A maintained npm profile looks great on a resume

Community — Others might find your solution useful

Practice — Learn about semver, CI/CD, and open source maintenance

Step 1: The Idea

❌ my-super-utils → Too vague ❌ awesome-everything → Does too much ❌ helper-functions → Not specific enough
