This week there is a lot of noise in the JS ecosystem, on various trends. But the most noticeable is about Yarn. Yet another package manager for js, that states it opens a war against NPM (in soft terms but clearly enough). The long post from Facebook about it demonstrates a clear effort to push things forward about NPM shortcomings. The reaction on hacker news is pretty verbose.
But for real, it was more than time that the supremacy of NPM was questioned. It has a lot of flaws and the number of posts about this event proves that the community was kind of waiting for something like this to happen. Like this cheatsheet, various articles like this one, this enthusiastic post from Yehuda Kats. But not everybody is happy about how things are done.
Personally, I like the technical direction it takes. But I hope that like io.js went back to node.js, it will eventually merge back to NPM, really. But I have the feeling it is not going to happen.
