What is bufrw?

The 'bufrw' npm package is a buffer read/write library designed to facilitate the reading and writing of binary data. It provides a set of tools to handle binary data serialization and deserialization, making it easier to work with binary protocols.

What are bufrw's main functionalities?

Buffer Reading

This feature allows you to read binary data from a buffer. In this example, a 32-bit unsigned integer is read from a buffer in big-endian format.

const bufrw = require('bufrw');
const buffer = Buffer.from([0x01, 0x02, 0x03, 0x04]);
const result = bufrw.UInt32BE.readFrom(buffer, 0);
console.log(result.value); // 16909060

Buffer Writing

This feature allows you to write binary data into a buffer. In this example, a 32-bit unsigned integer is written into a buffer in big-endian format.

const bufrw = require('bufrw');
const buffer = Buffer.alloc(4);
bufrw.UInt32BE.writeInto(16909060, buffer, 0);
console.log(buffer); // <Buffer 01 02 03 04>

Custom Serialization

This feature allows you to define custom serialization structures. In this example, a structure consisting of an 8-bit unsigned integer followed by a 16-bit unsigned integer in big-endian format is defined and written into a buffer.

const bufrw = require('bufrw');
const MyStruct = bufrw.Struct([bufrw.UInt8, bufrw.UInt16BE]);
const buffer = Buffer.alloc(3);
MyStruct.writeInto([0x01, 0x0203], buffer, 0);
console.log(buffer); // <Buffer 01 02 03>
