• Release:

At Chatroulette we have developed a Pulsar client library for Haskell - Supernova. The repository is here: https://github.com/cr-org/supernova and the library is here: https://hackage.haskell.org/package/supernova We would like to contribute the project back to the Pulsar community.

Motivation

Currently, there are no official client libraries for Haskell. Therefore we have written one entirely in Haskell (implementing the binary protocol).

Features

Supernova only implements some basic functionality.

• Service discovery (LOOKUP).
• Producing message with/without metadata.
• Consuming messages using all subscription types and seeking.

Licenses

Supernova is licensed under the Apache License Version 2.0 and it has the following dependencies - listed on Hackage.

• async, base, bifunctor, binary, bytestring, crc32c, exceptions, lens-family-core, lens-family-th, managed, mtl, network, proto-lens and proto-lens-runtime licensed under BSD-3-Clause.
• logging licensed under MIT.
• text licensed under BSD-2-Clause.

We are looking forward to any feedback.
