A Node.js Buffer API implementation for browsers, enabling binary data manipulation in web applications.
Buffer is a JavaScript library that implements the Node.js Buffer API for web browsers, enabling developers to manipulate binary data in browser environments. It solves the problem of working with binary data in web applications by providing the same familiar Buffer interface available in Node.js, allowing code to run consistently across both server and client environments.
JavaScript developers building web applications that need to handle binary data, particularly those using Browserify or working with npm modules that depend on Node.js Buffer functionality in the browser.
Developers choose Buffer because it provides 100% API compatibility with Node.js Buffer, excellent performance through Typed Array backing, and a small bundle size, making it the most reliable way to use Buffer APIs in browsers without worrying about compatibility issues.
The buffer module from node.js, for the browser.

Provides a 100% identical API to Node.js Buffer, enabling seamless code sharing between server and client environments without modifications.
Backed by Typed Arrays (Uint8Array/ArrayBuffer), ensuring fast binary operations as demonstrated in comprehensive browser benchmarks in the README.
Only 6.75KB minified + gzipped, adding negligible overhead to web applications while delivering full Buffer functionality.
Works in Chrome, Firefox, Edge, Safari 11+, iOS 11+, Android, covering all modern browsers with thorough testing via Saucelabs.
Does not modify browser prototypes or pollute the global window object, ensuring safe and unobtrusive usage in any project.
Benchmarks in the README show it can be slower than native Uint8Array for operations like concat, copy, and new buffer creation, due to the abstraction layer.
For automatic inclusion, it relies on Browserify or similar bundlers, which might not fit all build systems and requires additional setup for standalone use.
In Node.js environments, the native Buffer module is available, making this library unnecessary and potentially confusing in isomorphic codebases.
It tracks the latest (unstable) Node.js Buffer API, which, while considered stable, could introduce breaking changes if Node.js updates its API, affecting compatibility.
