xBuffer

xBuffer xBuffer is a lightweight JavaScript library that provides buffer-like functionality for browsers, similar to Node.js's Buffer. It offers efficient manipulation of binary data and supports common encoding and decoding operations, such as base64, hex, and UTF-8.

Features

• Binary Data Manipulation: Efficiently manipulate binary data in the browser, similar to Node.js Buffer.
• Encoding & Decoding: Supports a variety of encoding formats including base64, hex, and UTF-8.
• Buffer-like API: Follows the Buffer API pattern from Node.js, offering familiar methods for developers transitioning between the browser and Node.js environments.
• Efficient and Lightweight: Built on top of Uint8Array, ensuring high performance and a small footprint in web environments.

Installation

To install xBuffer, use either npm or yarn:

npm install @remotex-labs/xbuffer
# or
yarn add @remotex-labs/xbuffer

# Usage
## Creating a Buffer
```typescript
import { Buffer } from '@remotex-labs/xbuffer';

// Create a buffer from a string
const buffer = Buffer.from('Hello, world!', 'utf-8');

// Create a buffer from an array of bytes
const byteArray = new Uint8Array([72, 101, 108, 108, 111]);
const bufferFromArray = Buffer.from(byteArray);

Encoding and Decoding

You can use xBuffer for common encoding and decoding tasks, such as converting binary data to base64 or hex:

// Encode a buffer to base64
const base64String = buffer.toString('base64');

// Decode base64 to a buffer
const decodedBuffer = Buffer.from(base64String, 'base64');

// Encode a buffer to hex
const hexString = buffer.toString('hex');

// Decode hex to a buffer
const decodedHexBuffer = Buffer.from(hexString, 'hex');

Global Functions

setGlobalBuffer

This function sets the global Buffer object on globalThis, making it available throughout the environment. It is useful when Buffer is not natively available, such as in certain browser contexts.

import { setGlobalBuffer } from '@remotex-labs/xbuffer';

// Set `Buffer` globally
setGlobalBuffer();

// Now `Buffer` is accessible globally
console.log(Buffer); // Logs the global Buffer object

supportUtilInspect

This function modifies the global console.log to support custom inspection of objects that implement the util.inspect.custom symbol. It enables objects with custom inspection methods to be logged with their custom output.

import { supportUtilInspect } from '@remotex-labs/xbuffer';

// Enable custom inspect support
supportUtilInspect();

// Example object with custom inspection logic
const myObject = {
  [Symbol.for('nodejs.util.inspect.custom')]: () => 'Custom inspection logic here',
};

// Log the object
console.log(myObject); // Logs: "Custom inspection logic here"
