otobus/event_bus

This system is an Elixir-based event bus library designed for managing asynchronous event processing and subscription management. It provides a modular architecture with dedicated components for topics, subscriptions, notifications, observations, and data storage, all operating as independent GenServers. The system supports structured event models with metadata and timing, allowing developers to register subscribers and handle events with configurable behavior and robust error handling.

How it got here

2017 · EventBus architecture refactoring

This period focused on initializing the project infrastructure and significantly refactoring the EventBus library to replace a monolithic GenServer architecture with a modular, typed system of specialized child processes. The changes introduced a structured Event model and updated configuration files to modern Elixir standards, supported by comprehensive test coverage for the new components.

2018 · Event bus refactoring and test coverage

The event bus system was restructured by splitting monolithic services into dedicated modules for notification, observation, storage, and subscription. This refactoring was accompanied by the creation of new utility modules for time and ID generation, with comprehensive test coverage added for all new and refactored components.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 20 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit af047b7549 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.17. Score the same commit under that rubric and you get the same number.
