wonka

What is wonka?

The wonka package is a lightweight but powerful stream library for TypeScript and JavaScript. It allows for the creation, manipulation, and consumption of streams of values over time. It's particularly useful for handling asynchronous operations and events in a functional reactive programming style.

What are wonka's main functionalities?

Creating streams

This feature allows for the creation of streams from various sources. In this example, a stream is created from an array.

import { fromArray } from 'wonka';
const stream = fromArray([1, 2, 3]);

Transforming streams

This feature demonstrates how to transform streams using operators like `map`. In the example, each value in the stream is doubled.

import { fromArray, map } from 'wonka';
const stream = fromArray([1, 2, 3]);
const doubled = map(x => x * 2)(stream);

Consuming streams

This feature shows how to consume streams. The `forEach` operator is used to log each value from the stream to the console.

import { fromArray, forEach } from 'wonka';
const stream = fromArray([1, 2, 3]);
forEach(x => console.log(x))(stream);

Other packages similar to wonka

rxjs

RxJS is a comprehensive library for reactive programming using Observables. It offers a wider range of operators than wonka, making it more powerful but also larger in size. It's well-suited for complex data flow scenarios.

xstream

xstream is a library designed for creating and working with streams of values. It's similar to wonka in its focus on streams but differs in API and operator availability. It's known for its simplicity and small bundle size.

most

Most.js is a high-performance reactive programming library. It focuses on providing a rich set of operators for composing asynchronous and event-based programs. It's known for its speed and efficiency compared to other streaming libraries.

Wonka

A tiny but capable push & pull stream library for TypeScript and Flow, loosely following the callbag spec

NOTE: The currently released version v6 is only compatible now with TypeScript, Flow, and JavaScript. If you're looking for Reason/OCaml/esy/dune support, please check v5, and if you're looking for the legacy version of this library check v4.

“There’s no earthly way of knowing
Which direction we are going
There’s no knowing where we’re rowing
Or which way the river’s flowing” － Willy Wonka

Wonka is a lightweight iterable and observable library loosely based on the callbag spec. It exposes a set of helpers to create streams, which are sources of multiple values, which allow you to create, transform and consume event streams or iterable sets of data.
