In an effort to build an Haskell client library for the Firebase service [0], which rely heavily on HTTP event source/server sent events [1], I am looking for an HTTP client lib supporting this spec.

AFAIK, both WAI and yesod handle the mechanism server-side but nor http-client, wreq or http-streams seem to provide the client counterpart.

Am I looking in the wrong direction?

At least http-client and http-streams should support this use case easily, you'll just have to parse the stream yourself. The easiest way is to write a parser using attoparsec and lift that into a stream transformer. The io-streams library has native support for this (http://hackage.haskell.org/package/io-streams-1.3.0.0/docs/System-IO-Streams-Attoparsec.html#v:parserToInputStream), conduits supply a similar thing in the conduit-extra package.
