What I did for a mobile web app I built last year after the react prototype was to slow on old devices: - Render all pages/routes/states into a single html file (size ~2mb) but each page/component/state hidden via style=display:none;. - then write some hand crafted js (few hundred lines) to add event listeners to forms and show/hide the components depending on url change - cache everything via appcache/serviceworker…
This is the worst approach I've ever read about.
why? It solved all the probles the previous implementations had and was even easier to implement.
