@types/readable-stream

What is @types/readable-stream?

The @types/readable-stream package provides TypeScript type definitions for the readable-stream package, which is a userland implementation of the Streams API from Node.js. This allows developers to use and interact with streams in a type-safe manner, ensuring that the code adheres to the expected interfaces and behaviors of streams.

What are @types/readable-stream's main functionalities?

Creating a readable stream

This feature allows you to create a readable stream that you can push data into. The stream can then be consumed by other parts of your application.

import { Readable } from 'readable-stream';

const readable = new Readable({
  read(size) {
    this.push('some data');
    this.push(null); // No more data
  }
});
readable.on('data', (chunk) => console.log(chunk.toString()));

Piping a readable stream to a writable stream

This demonstrates how to pipe data from a readable stream directly into a writable stream, effectively transferring data from one source to a destination.

import { Readable, Writable } from 'readable-stream';

const readable = new Readable({
  read(size) {
    this.push('data to write');
    this.push(null); // No more data
  }
});

const writable = new Writable({
  write(chunk, encoding, callback) {
    console.log(chunk.toString());
    callback();
  }
});

readable.pipe(writable);

Other packages similar to @types/readable-stream

stream

The 'stream' package is actually the native Node.js Streams module. It provides the foundational building blocks for working with streams in Node.js. Compared to @types/readable-stream, it does not require type definitions because it's part of Node.js itself, but using it in TypeScript projects without type definitions might not provide the same level of type safety.

through2

Through2 is a tiny wrapper around Node.js streams.Transform (Streams2/3) to avoid explicit subclassing noise. It's similar to @types/readable-stream in that it provides a simpler interface for working with streams, but it focuses more on transform streams and does not come with TypeScript types out of the box.

highland

Highland.js manages synchronous and asynchronous code easily, using nothing more than standard JavaScript and Node-like Streams. While it offers functionality similar to @types/readable-stream by working with streams, it also introduces utilities for handling asynchronous operations and managing backpressure, making it more of a utility library on top of streams rather than just type definitions.
