HTML over WebSockets: real-time SPAs with barely any JavaScript
SMRTR summary
HTML over WebSockets lets you build real-time, SPA-like apps in a single backend language — no JSON API, no frontend framework, no contracts. The server renders HTML and pushes it directly to the client over a persistent bidirectional channel. Frameworks like Phoenix LiveView, Django LiveView, and Blazor prove this pattern is production-ready, though it trades stateless simplicity for per-client server memory and scaling considerations.
