Books are still written, and there are quite a few online courses, and some of them aren't bad. I've learned that to be productive in a new language or framework I really need to dive into some of those resources. The manuals you find online are rarely good enough to learn from, and all the tutorials and "getting started" just scratches enough on the surface to make me frustrated.
