LiveView

Build real-time, interactive web applications using server-rendered HTML without writing custom JavaScript.

Phoenix LiveView eliminates the complexity of client-side SPAs by managing state on the server and pushing updates via persistent WebSockets. It handles user events, form validation, and data synchronization through Elixir's lightweight processes (Gleam or Erlang VM). By shipping only the diffs of changed HTML to the browser, LiveView achieves sub-100ms latency for dynamic UI components like live dashboards, chat systems, and autocomplete search bars. This architecture reduces your codebase by removing the need for REST/GraphQL APIs and heavy frontend frameworks like React or Vue.
