binutil

日本語のREADMEはこちらです: README.ja.md

A set of utility functions for handling binary data in JavaScript.

Features

• bin2short, short2bin: Convert between 16-bit short integers and binary data
• bin2i, i2bin: Convert between 32-bit integers and binary data
• subbin: Extract a subset of binary data
• setbin: Set a portion of binary data
• bincat: Concatenate multiple binary data
• eqbin: Compare binary data for equality

Usage

The binutil library is available as a set of standalone functions that can be imported and used in your JavaScript project.

import { bin2short, short2bin, i2bin, bin2i, bincat, eqbin, setbin, subbin } from 'binutil';

BinWriter and BinReader

The library also includes BinWriter and BinReader classes, which provide a more object-oriented interface for working with binary data.

import { BinWriter, BinReader } from 'binutil';

const writer = new BinWriter();
writer.writeUint32(123456);
writer.writeBytes(new Uint8Array([1, 2, 3]));
const data = writer.toBytes();

const reader = new BinReader(data);
const num = reader.readUint32();
const bytes = reader.readBytes(3);
