@beyond-js/crc32

A fast and efficient CRC32 (Cyclic Redundancy Check) implementation for Node.js and browser environments.

Installation

npm install @beyond-js/crc32

Usage

const crc32 = require('@beyond-js/crc32');

// Calculate CRC32 for a string
const result1 = crc32('Hello, World!');
console.log(result1); // Outputs a 32-bit unsigned integer

// Calculate CRC32 for a Buffer
const buffer = Buffer.from('Hello, World!', 'utf8');
const result2 = crc32(buffer);
console.log(result2); // Outputs the same 32-bit unsigned integer

API

The module exports a single function:

function crc32(input: string | Buffer): number

• input: The input data. Can be a string or a Buffer.
• Returns: A 32-bit unsigned integer representing the CRC32 checksum.

Features

• Works with both strings and Buffers
• Optimized for performance using a pre-computed lookup table
• Compatible with Node.js and browser environments (when bundled)
