I get the SPA movement. I’m a big proponent of it. If a user is navigating between many similar pages or wants high interactivity without a page load then you want to cache the views as js scripts via cdn and only download the data via REST calls to an api. It works well with mobile apps too. Both web app and mobile app talk to the same api. What I don’t get is the server hydration kungfu. If you’re rendering the template on the server then don’t do the same thing again with js and download the data twice. Just render html serverside and call it a day. Either app or a site. A tiny bit of jquery like JS snippets for banners and image galleries make sense but that shouldn’t be render blocking nor be in megabytes. I’m a big proponent of Preact over React. Same API but much smaller library. The difference is noticeable when browsing on 3G networks and low powered devices.
