The Buffer package replicates the Node.js Buffer API for use in the browser. It is designed for the manipulation of binary data with a wide range of features supporting different functionalities. The main goal of Buffer is to provide an API that is 100% identical to Node's Buffer API. This lets you manipulate binary data quickly and easily across virtually all popular web browsers. Buffer is backed by Typed Arrays and sports an impressively lean bundle size, making it ideal for light, speedy operations.
To use Buffer, you'll first have to install it through npm by running
npm install buffer. Once it's installed, you can use it directly in your project by executing
require('buffer') or using the
Buffer global. This module is mostly used with Browserify, which should automatically include it in your bundle.
If you want to depend on this module explicitly without using Browserify, you use
require('buffer/') to employ the npm module named 'buffer' instead of the Node.js core module named 'buffer'. Here's a brief snippet of how you might use Buffer:
var Buffer = require('buffer/').Buffer // note: the trailing slash is important!
Throughout the usage, you can reference the Node.js Buffer API as Buffer strives to mimic its functionality as closely as possible.
The official Buffer documentation, which contains a full list of properties, instance methods, and class methods that are supported, is available on the Node.js website. This is the most comprehensive guide to Buffer's functionality and should answer any questions you might have about how Buffers operates or what you might expect from it. You can also find information on how Buffer works and the benefits of using Buffer in the readme of the official Buffer GitHub page.
