What is any-observable?
The any-observable package allows you to register an Observable library of your choice and use it throughout your application as a singleton. This means you can use Observables without being locked into a specific library, providing flexibility in your codebase.
What are any-observable's main functionalities?
Registering a specific Observable implementation
This feature allows you to register an Observable implementation that will be used whenever you import 'any-observable'.
const anyObservable = require('any-observable');
anyObservable.register('rxjs'); // or 'zen-observable', etc.
Using the registered Observable
Once an Observable library is registered, you can create and use Observables as you would normally with that library.
const Observable = require('any-observable');
const stream = new Observable(observer => {
observer.next('Hello, World!');
observer.complete();
});
stream.subscribe({
next: console.log,
complete: () => console.log('Stream finished')
});

zen-observable
Zen Observable is a minimalistic library for Observables. It is smaller and has fewer features than RxJS, but can be used with any-observable to provide a consistent Observable interface.
observable-fns
Observable-fns is a lightweight Observable library that focuses on core functionality. It is similar to zen-observable and can also be used with any-observable.
