This is Pub/Sub for the Watermill project.
All Pub/Sub implementations can be found at https://watermill.io/pubsubs/.
Watermill is a Go library for working efficiently with message streams. It is intended for building event driven applications, enabling event sourcing, RPC over messages, sagas and basically whatever else comes to your mind. You can use conventional pub/sub implementations like Kafka or RabbitMQ, but also HTTP or MySQL binlog if that fits your use case.

All contributions are very much welcome. If you'd like to help with Watermill development, please see open issues and submit your pull request via GitHub.
The tests expect a running instance of PubSub. You can run the emulator specified in the docker-compose.yml, then set the correct env variable by running the following:
make up
PUBSUB_EMULATOR_HOST=localhost:8085 make test
Running one test:
make up
PUBSUB_EMULATOR_HOST=localhost:8085 go test -v ./... -run TestPublishSubscribe/TestContinueAfterSubscribeClose
