Servant Subscriber

Build Status

Servant-subscriber enables you clients to subscribe to resources in your servant-api (an API endpoint). Servant-subscriber will then notify the client via a WebSocket connection whenever the resource changes, thus the client can easily stay up to date with a resource.


It seems to work - it is already tested in examples/central-counter of servant-purescript and used in production.

Still missing:

  • Documentation, announcement.
  • Tests
