A pure Haskell MQTT client and server implementation Travis

Project goal

This project aims to supply a rock-solid MQTT 3.1.1 implementation suitable for production use.

The planned features are:

  • A broker implementation capable of handing and serving several thousands of connections.
  • A client implementation with integrated broker which allows one client to be used by several threads/consumers simultaneously.
  • TLS and WebSocket connections.
  • An interface for pluggable authentication and authorization.
  • High test and benchmark coverage.

Project state (2017-03-22)

  • The broker implementation is nearly feature complete and well-tested. The hummingbird project is a full-fledged broker built on-top of this library.
  • The client implementation went out of focus for now and is currently commented out. It's still a planned feature and is essentially a low hanging fruit as all the protocol parsers etc. are already in place.
