Watermill Release Post

Hey, it’s been a long time! We’re happy to share that Watermill v1.3 is now out! What is Watermill Watermill is an open-source library for building message-driven or event-driven applications the easy way in Go. Our definition of “easy” is as easy as building an HTTP server in Go. With all that, it’s a library, not a framework. So your application is not tied to Watermill forever.

After almost three years since the last stable release, Watermill v1.2 is finally out! If you’re new here, Watermill is our open-source library for building event-driven applications in Go, the easy way. A lot has happened since v1.1. We’ve been running Watermill on production in many projects, using it in new ways and adding features to support new use cases. We also received a lot of feedback and contributions from the community.

54 days of work, 12,909 lines of code, 47 Monsters and 42 KFC Twisters later finally it is Watermill v0.3.0! To keep it short, let’s go through the changes. One important thing: at the end of this post there is a 3 question survey. Please take a moment to fill it out, it will help us make Watermill even better.

Let me start by thanking all contributors for feedback on Watermill - it drives us to add new features. Thanks! It’s been almost a month since the initial release of Watermill. However, it’s just the beginning and we are still working hard to ship new features. What is new in Watermill 0.2? Documentation - watermill.io Godoc is great. However, it’s functionality is sometimes too limited to express more complicated documentation.

Watermill is a Go library for working efficiently with message streams. It is intended as a library for building event-driven applications, enabling event sourcing, CQRS, RPC over messages, sagas. Why? Lack of standard messaging library There are many third party and standard library tools which help to implement standardized RPC or HTTP communication in Golang. There are also multiple third party HTTP routers and frameworks.
