Isn't it ironic that, as we are moving away from fat servers, we are now writing even fatter clients ( which still need a server since one wants in many case to be able to render pages server side and one has to serve static assets anyway ) . So what is the concrete difference between an API + a node-js server to serve assets and render templates server-side (so with a lot of business logic) + an angular2 client written in typescript , all this VS something like Rich Faces or Prime Faces in a servlet container ? We just rebuild the exact same thing that is hated by most "modern developers", with worse tooling on top of it. Both solutions need a third party language that is not Javascript, both solutions need a compilation step, and command line tools(or an IDE in the case of Java). Some will say "Well, now the client and server are independent, and if the server changes, one can keep the fat client". But in practice, which side gets rewritten ? the server or the client with the "framework du jour" ?
