I don't think raw jQuery is often used to build full dynamic frontends and SPAs. It's typically used to bolt on effects, transitions and asynchronous data fetching into otherwise statically generated server-side web pages. Although SPAs, frontend frameworks and the model of communicating microservices is gaining lots of traction and visibility for web applications (particularly paid services that replace former desktop apps), plain old server-side CRUD that renders template variables from a data model is still going to be the dominant paradigm on the web at large, not to mention more of a conceptual neat fit to begin with. In some ways I predict there will be a sort of resurgence in server-side CRUD frameworks again as being the hot trend you read about on HN, once people found out that you can easily build real-time, reactive UIs without having to context switch and directly deal with the often subpar client-side interfaces. Furthermore, the act of generating HTML and JavaScript from native language constructs will be lauded as a great time-saver, not to mention giving the same benefits of the so-called "isomorphism" that platforms like Node are hailed for. For examples of these concepts, see the Nitrogen and N2O frameworks (both Erlang).
