Client-side consumption of the ServerEvent type from wai-extra via the streaming ecosystem.

ServerEvent Stream

withEvents :: Request -> Manager -> (Stream (Of ServerEvent) IO () -> IO a) -> IO a

Methods

fromEvent :: ByteString -> Maybe a

dataOnly :: (FromEvent a, Monad m) => Stream (Of ServerEvent) m r -> Stream (Of a) m r

A stream of only the data fields of each consumed ServerEvent. Assumes that each data field contains bytes of identical format, i.e. decodable by FromEvent. Silently skips over decoding failures.
