I’m a front-end developer. Whenever I need to introduce a new library or framework into the project, I always wonder if this tool is the best choice we have? How about its alternative? It always triggers my decidophobia.

I think one kind of data I can refer to is how many real repositories use it. So I crawl the JS projects on GitHub and record their dependencies usage and build a website called npmusage to check whether I should use it or not. More than 85K repositories have been fetched already.
