Phoenix (web framework) explained

Phoenix is a web development framework written in the functional programming language Elixir.

Details

Phoenix uses a server-side model–view–controller (MVC) pattern.^[1] Based on the Plug library,^[2] and ultimately the Erlang HTTP server Cowboy,^[3] it was developed to provide highly performant and scalable web applications. In addition to the request/response functionality provided by the underlying Cowboy server,^[4] Phoenix provides soft realtime communication to external clients through WebSockets or long polling using its language agnostic channels feature.^{[5] [6]}

Two notable features of Phoenix are LiveView and HEEx. LiveView provides real-time user experiences with server-rendered HTML over HTTP and WebSocket.^[7] HEEx is Phoenix's templating language which provides HTML-aware compile time checking.^[8]
