What is web-encoding?

The web-encoding package provides a polyfill for the TextEncoder and TextDecoder interfaces, which are part of the Encoding Living Standard. These interfaces allow for high-performance encoding and decoding of text in various character encodings, primarily UTF-8.

What are web-encoding's main functionalities?

Text Encoding

This feature allows you to encode a JavaScript string into a Uint8Array of bytes using UTF-8 encoding. It is useful for preparing text data for network transmission or storage.

const { TextEncoder } = require('web-encoding');
const encoder = new TextEncoder();
const encoded = encoder.encode('Hello, world!');
console.log(encoded);

Text Decoding

This feature enables decoding of a Uint8Array of bytes into a JavaScript string using UTF-8 or other supported character encodings. It is essential for reading text data received from a network or read from binary storage.

const { TextDecoder } = require('web-encoding');
const decoder = new TextDecoder('utf-8');
const decoded = decoder.decode(new Uint8Array([72, 101, 108, 108, 111]));
console.log(decoded);
