What is buffer-alloc?

The buffer-alloc package is a utility for allocating buffer memory in Node.js. It provides a way to create a buffer of a specified size filled with zeros or another specified value. This is particularly useful in scenarios where you need to ensure that newly allocated memory does not contain old or sensitive data. It mimics the Buffer.alloc method introduced in Node.js v5.10.0, offering a polyfill for older versions of Node.js or an alternative method for newer versions.

What are buffer-alloc's main functionalities?

Allocating a buffer filled with zeros

This feature allows for the creation of a new buffer of a specified size, with each byte initialized to zero. It's useful for when you need a clean buffer with no pre-existing data.

const bufferAlloc = require('buffer-alloc');
const buffer = bufferAlloc(10); // creates a 10-byte buffer filled with zeros

Allocating a buffer filled with a specific value

This feature enables the creation of a buffer where each byte is initialized to a specific value provided by the user. This can be useful for initializing a buffer to a non-zero state for specific use cases.

const bufferAlloc = require('buffer-alloc');
const buffer = bufferAlloc(10, 0x1); // creates a 10-byte buffer filled with 0x1
