Looking at web user interface libraries. I have at least one project that would like some UI functionality with a PHP/Restful back-end and much of its content likely rendered in a canvas using WebGL (and probably three.js but I’m not familiar enough to be certain).

Angular, bootstrap, JQueryUI seem to be names that come up in searches. Angular 2 downplays its UI aspect. I’ve got quite a few books in this area that I’ve read parts of. In the end I expect I’ll just pick something that I have decent documentation for and dive in. Given the WebGL aspects, I expect that much of the heavy lifting won’t really care which kit of tools (or any) I use.
