Angular Server-Sent Events Client

ngx-sse-client is an Angular library providing a robust client for Server-Sent Events (SSE), designed as an alternative to the native `EventSource` API. Currently at stable version 21.0.0, this package typically releases new major versions in alignment with Angular's own major releases, ensuring compatibility with the latest Angular ecosystem. Its key differentiator lies in leveraging Angular's `HttpClient` for SSE stream requests, which enables seamless integration with `HttpInterceptor` for authentication, logging, and error handling. It also supports flexible HTTP methods (e.g., POST instead of just GET) and exposes event streams as RxJS Observables, aligning with Angular's reactive programming paradigm. This allows for more advanced control and error management compared to traditional `EventSource` implementations, which lack interceptor support and direct Observable integration.
