github.com/mustafaturan/bus/v2 (go): Package bus is a minimalist event/message bus implementation for internal communication  The package requires a unique id generator to assign ids to events. You can write your own function to generate unique ids or use a package that provides unique id generation functionality.  The `bus` package respect to software design choice of the packages/projects. It supports both singleton and dependency injection to init a `bus` instance.  Here is a sample initilization using `monoton` id generator:  Example code for configuration:  To emit events to the topics, topic names should be registered first:  Example code:  To receive topic events you need to register handlers; A handler basically requires two vals which are a `Handle` function and topic `Matcher` regex pattern.  Example code:  Example code:  When an event is emitted, the topic handlers receive the event synchronously. It is highly recommended to process events asynchronous. Package leave the decision to the packages/projects to use concurrency abstractions depending on use-cases. Each handlers receive the same event as ref of `bus.Event` struct.
