Questions tagged [sente]

For questions regarding the Sente web socket Clojure(Script) library.

Sente is a library in/for Clojure and ClojureScript for implementing websocket communication with AJAX fallback.

Features

  • Bidirectional a/sync comms over both WebSockets and Ajax (auto-fallback)
  • It just works: auto keep-alives, buffering, protocol selection, reconnects
  • Efficient design incl. transparent event batching for low-bandwidth use, even over Ajax
  • Send arbitrary Clojure vals over edn or Transit (JSON, MessagePack, etc.)
  • Tiny API: make-channel-socket! and you're good to go
  • Automatic, sensible support for users connected with multiple clients and/or devices simultaneously
  • Realtime info on which users are connected over which protocols (v0.10.0+)
  • Flexible model: use it anywhere you'd use WebSockets/Ajax/Socket.IO, etc.
  • Standard Ring security model: auth as you like, HTTPS when available, CSRF support, etc.
  • Fully documented, with examples
  • Small codebase: ~1.5k lines for the entire client+server implementation
  • Supported servers: http-kit, Immutant v2+, nginx-clojure, node.js, Aleph
