Thin wrapper around zen-observable and @types/zen-observable, to support ESM exports as well as CommonJS exports
The zen-observable-ts package is a TypeScript implementation of the Observable pattern, which is used for handling asynchronous data streams. It provides a way to create, transform, and consume sequences of values over time, making it useful for scenarios such as event handling, data fetching, and reactive programming.
Creating an Observable
This feature allows you to create an Observable that emits a sequence of values. In this example, the Observable emits 'Hello' and 'World' before completing.
const { Observable } = require('zen-observable-ts');
const observable = new Observable(observer => {
observer.next('Hello');
observer.next('World');
observer.complete();
});
observable.subscribe({
next(value) { console.log(value); },
complete() { console.log('Done'); }
});
Transforming Observables with map
This feature allows you to transform the values emitted by an Observable using the map operator. In this example, each value emitted by the original Observable is multiplied by 2.
const { Observable } = require('zen-observable-ts');
const observable = new Observable(observer => {
observer.next(1);
observer.next(2);
observer.next(3);
observer.complete();
});
const mappedObservable = observable.map(value => value * 2);
mappedObservable.subscribe({
next(value) { console.log(value); },
complete() { console.log('Done'); }
});
Filtering Observables with filter
This feature allows you to filter the values emitted by an Observable using the filter operator. In this example, only values greater than 1 are emitted.
const { Observable } = require('zen-observable-ts');
const observable = new Observable(observer => {
observer.next(1);
observer.next(2);
observer.next(3);
observer.complete();
});
const filteredObservable = observable.filter(value => value > 1);
filteredObservable.subscribe({
next(value) { console.log(value); },
complete() { console.log('Done'); }
});
Combining Observables with merge
This feature allows you to combine multiple Observables into a single Observable using the merge operator. In this example, the values from both observables are emitted in sequence.
const { Observable } = require('zen-observable-ts');
const observable1 = new Observable(observer => {
observer.next('A');
observer.complete();
});
const observable2 = new Observable(observer => {
observer.next('B');
observer.complete();
});
const mergedObservable = Observable.merge(observable1, observable2);
mergedObservable.subscribe({
next(value) { console.log(value); },
complete() { console.log('Done'); }
});
RxJS is a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code. It is more feature-rich and widely used compared to zen-observable-ts, offering a comprehensive set of operators and utilities for working with Observables.
Bacon.js is a functional reactive programming library for JavaScript. It provides a way to work with events and asynchronous data streams. Compared to zen-observable-ts, Bacon.js offers a different API and focuses more on functional programming paradigms.
Most.js is a high-performance reactive programming library that focuses on speed and efficiency. It provides a minimalistic API for working with streams. Compared to zen-observable-ts, Most.js is designed to be highly performant and is suitable for applications where performance is critical.
Thin wrapper around zen-observable
and @types/zen-observable
, to support ESM exports as well as CommonJS exports, with TypeScript types provided by @types/zen-observable
.
After installing zen-observable-ts
using a tool like npm or yarn, you can import the Observable
class by name:
import { Observable } from "zen-observable-ts";
Note that this package does not currently have a default export, so the {}
braces are mandatory.
This tiny wrapper package replaces an older version of zen-observable-ts
that used to provide TypeScript types for zen-observable
, before @types/zen-observable
was introduced. This version of the package is not intended to be perfectly compatible with the older version, so we have bumped the major version of the package to reflect the difference.
As explained in https://github.com/apollographql/apollo-client/pull/7615, the zen-observable-ts
package exists to fill a gap in the functionality of the zen-observable
package, so we will retire this package in favor of using zen-observable
directly, when/if this PR is ever merged.
