EventBus is traceable, extendable and minimalist event bus implementation for Elixir with built-in event store and event watcher based on ETS. https://hexdocs.pm/event_bus

[1.3.x]

The latest version of EventBus comes with a few additional helpers to make development easier. Majority of the updates are related with EventBus.EventSource helper module:

• Set default transaction id to the event’s id
• Add random id generator for Event builder
• Introduce fetch_event_data function to fetch only event data
• Log empty topic listeners
• Add missing tests for existence check
• Update time spent calculation for EventSource block
• Remove support for system event tracing (Updated the wiki to create a wrapper for system event tracing)
