ngx-event-bus-lib

ngx-event-bus is a global event bus library for Angular that enables strongly-typed event communication across any part of an application. It provides a clean, declarative alternative to traditional Angular communication patterns like shared services, dependency injection, and RxJS subjects, promoting loose coupling and reducing boilerplate.

Key Features

• Strongly-Typed Events — Broadcast events with fully typed payloads, ensuring type safety and better developer experience with IDE autocompletion.
• Declarative Interception — Use the @Interceptor decorator to declaratively listen for events without manual lifecycle management.
• Memory Leak Prevention — Automatically manages event listener addition and removal to prevent memory leaks.
• Targeted Events — Optionally broadcast events with a specific key to ensure only intended interceptors react.
• Zero Shared State — Operates without shared state, services, or dependency injection, simplifying architecture.
• Angular Universal Compatible — Fully supports server-side rendering (SSR) and works with all Angular entities (components, directives, services, pipes).
• Flexible Typing Levels — Supports three levels of type enforcement, from quick untyped usage to fully enforced, refactor-safe custom event classes.

Philosophy

ngx-event-bus is built on native JavaScript events and a decorator-based API to provide a simple, scalable, and type-safe communication layer that lets developers focus on intent rather than wiring.
