Elixir + Phoenix + LiveView overview

Elixir web stack: Phoenix framework with LiveView for real-time, server-rendered interactive UIs over a persistent WebSocket. LiveView eliminates the need for a separate JavaScript SPA framework by rendering HTML server-side and pushing minimal diffs to the client. This stack is characterized by extremely low latency, massive concurrency via BEAM lightweight processes, and a single-language full-stack experience. Ecto is the canonical database library (typically with PostgreSQL). OTP supervision trees provide fault isolation. Tailwind CSS and esbuild are the standard frontend tooling alongside LiveView.
