ngx-error-handling
An Angular library that automatically captures and centralizes unhandled RxJS, signal, and classic errors into a single observable stream.
Overview
NgxErrorHandling is an Angular library designed to provide a unified error handling system for modern Angular applications. It addresses the challenge of errors being memoized in Angular signals by capturing unhandled errors from multiple sources and making them available through a centralized RxJS Subject called the ErrorBus.
Key Features
- Unified Error Capture — Automatically intercepts unhandled errors from RxJS streams, Angular signals, and classic JavaScript errors.
- ErrorBus Service — Centralizes all captured errors into a single RxJS Subject, allowing any component to subscribe and react.
- Safe Signal Wrapper — Provides a
safeSignal()function to replacecomputed()andtoSignal(), preventing errors from being memoized and re-thrown. - Modular Sensors — Offers configurable error captors (sensors) for signals, HTTP interceptors, and the global ErrorHandler.
- Flexible Notification — Decouples error capture from presentation, allowing developers to implement custom user notification (e.g., toasters) by subscribing to the ErrorBus.
Philosophy
The library follows a modular, sensor-based architecture that separates error detection, centralization, and notification, giving developers fine-grained control over error handling while ensuring no error goes unobserved.
