I'm using meteor to get something done and I needed to implement "likes" as in something you can click to "like" something and then that thing can display a number of likes.
There's a package that helps with this in meteor. It's called "socialize likeable" and it seems fine. The code is not too big. I skimmed the code to see what it was doing. Before that I had thought about different ways to implement such a feature and from reading that code helped inform my own ideas about the what was probably the right way to do things. It was doing it that way so I go to install it
It installs 9 more dependencies
