How does bytebuffer.default work?

bytebuffer.default is a function in the ByteBuffer library that can be used to create a new byte buffer object for working with binary data in JavaScript.

When bytebuffer.default is called, it takes one or more arguments, which specify the initial capacity, the little-endian or big-endian byte order, or the initial contents of the byte buffer. The arguments can be numbers, strings, or other byte buffer objects.

Once the byte buffer object is created, it can be used to read or write binary data using methods such as putInt8, putInt16, putInt32, putFloat32, or putFloat64 for writing data, or getInt8, getInt16, getInt32, getFloat32, or getFloat64 for reading data.

The byte buffer object also provides methods for changing the byte order, for setting and getting the position and limit of the buffer, for slicing or copying parts of the buffer, and for converting to and from other data types, such as strings or arrays.

By default, bytebuffer.default uses a little-endian byte order, but this can be changed using the littleEndian option. The byte buffer object can also be resized dynamically using methods such as resize, compact, or flip.

Overall, bytebuffer.default provides a powerful way to work with binary data in JavaScript, allowing developers to read or write data in various formats and manipulate it easily.

const ByteBuffer = require("bytebuffer");

// Create a new byte buffer object with an initial capacity of 16 bytes
const myBuffer = new ByteBuffer(16);

// Write binary data to the buffer using various methods
myBuffer.putInt8(10);
myBuffer.putInt16(256);
myBuffer.putFloat32(3.14159);

// Read binary data from the buffer using various methods
const value1 = myBuffer.getInt8();
const value2 = myBuffer.getInt16();
const value3 = myBuffer.getFloat32();

console.log("Value 1:", value1);
console.log("Value 2:", value2);
console.log("Value 3:", value3);

// Convert the buffer to a base64-encoded string
const base64String = myBuffer.toBase64();

console.log("Base64 string:", base64String);

// Create a new byte buffer object from a hex string
const hexString = "0a000100c3f54840";
const fromHexBuffer = new ByteBuffer.fromHex(hexString);

console.log("From hex:", fromHexBuffer.toDebug());

In this example, we use bytebuffer.default to create and work with a byte buffer object in JavaScript. We call new ByteBuffer(16) to create a new byte buffer object with an initial capacity of 16 bytes. We then write binary data to the buffer using various methods such as putInt8, putInt16, and putFloat32. We read binary data from the buffer using various methods such as getInt8, getInt16, and getFloat32. We then convert the buffer to a base64-encoded string using the toBase64 method. Finally, we create a new byte buffer object from a hex string using the fromHex method and log its contents to the console using the toDebug method. This example shows how bytebuffer.default can be used to work with binary data in JavaScript, providing developers with a flexible and powerful way to read, write, and manipulate binary data in various formats.
