It’s Autumn over here, and it usually means another release of Watermill! 🍂 It’s hard to believe it’s already been five years since the v1.0 release.

Watermill is a Go library for building message-driven or event-driven applications the easy way. Think of it like an HTTP router but for messages. It’s a library, not a framework, so you don’t need to change your architecture to use it.

Over the last year, Watermill grew to 7.5k GitHub stars and 55 contributors, just on the main repository. It supports 12 Pub/Subs including Kafka, Redis Streams, NATS, Google Cloud Pub/Sub, Amazon SQS/SNS, SQL, and RabbitMQ.

Watermill 1.0 was released in 2019, and the public API has been stable. I especially like the modular design, which allows you to combine low-level components like building blocks to create more complex features. You can see this in rather simple logic of components like FanIn, FanOut, or the Forwarder.

You can also notice this approach in the new features described below. We added a few simple components that work well separately, but you can combine them for more interesting effects.
