@stablelib/bytes

What is @stablelib/bytes?

@stablelib/bytes is a utility library for working with byte arrays in JavaScript. It provides a variety of functions for manipulating and converting byte arrays, making it easier to handle binary data.

What are @stablelib/bytes's main functionalities?

Concatenation

This feature allows you to concatenate multiple byte arrays into a single byte array.

const bytes = require('@stablelib/bytes');
const array1 = new Uint8Array([1, 2, 3]);
const array2 = new Uint8Array([4, 5, 6]);
const concatenated = bytes.concat(array1, array2);
console.log(concatenated); // Uint8Array [1, 2, 3, 4, 5, 6]

Equality Check

This feature allows you to check if two byte arrays are equal.

const bytes = require('@stablelib/bytes');
const array1 = new Uint8Array([1, 2, 3]);
const array2 = new Uint8Array([1, 2, 3]);
const isEqual = bytes.equal(array1, array2);
console.log(isEqual); // true

Subarray Extraction

This feature allows you to extract a subarray from a given byte array.

const bytes = require('@stablelib/bytes');
const array = new Uint8Array([1, 2, 3, 4, 5]);
const subarray = bytes.subarray(array, 1, 3);
console.log(subarray); // Uint8Array [2, 3]

Hex Encoding/Decoding

This feature allows you to encode a byte array to a hex string and decode a hex string back to a byte array.

const bytes = require('@stablelib/bytes');
const array = new Uint8Array([1, 2, 3]);
const hexString = bytes.toHex(array);
console.log(hexString); // '010203'
const decodedArray = bytes.fromHex(hexString);
console.log(decodedArray); // Uint8Array [1, 2, 3]

Other packages similar to @stablelib/bytes

buffer

The 'buffer' module from Node.js provides a way of handling binary data directly in JavaScript. It offers similar functionalities such as concatenation, slicing, and encoding/decoding. However, it is more tightly integrated with Node.js and may not be as lightweight as @stablelib/bytes.

typedarray

The 'typedarray' package provides polyfills for JavaScript typed arrays, which are used for handling binary data. While it offers basic functionalities for working with byte arrays, it does not provide as many utility functions as @stablelib/bytes.

arraybuffer-utils

The 'arraybuffer-utils' package provides utility functions for working with ArrayBuffers and TypedArrays. It offers functionalities like concatenation, slicing, and conversion between different types of arrays. It is similar to @stablelib/bytes but may have a different API and set of features.
