Npmtrends is a pretty good source: https://www.npmtrends.com/react-vs-vue-vs-@angular/core-vs-@... Vue has carved out a huge piece of the browser market, but it appears to have reached its peak.
React is hard to stop at this point as it swept over to other platforms. If it really gets to drive platforms with a single component standard and a unified events system, on the web, ios, android, windows, mac, linux, then i don't think a web framework will hold against this much longer tbh.
