Revision history for servant-event-stream

0.3.0.0 -- 2024-09-05

Breaking changes to the API.

Event streams are implemented using servant's 'Stream' endpoint. You should provide a handler that returns a stream of events that implements 'ToSourceIO' where events have a 'ToServerEvent' instance.

Example:

type MyApi = "books" :> ServerSentEvents (SourceIO Book)

instance ToServerEvent Book where toServerEvent book = ...

server :: Server MyApi server = streamBooks where streamBooks :: Handler (SourceIO Book) streamBooks = pure $ source [book1, ...]
