buffer

buffer is a JavaScript implementation of Node.js Buffer functionality designed to provide binary data handling capabilities in browser environments and cross-platform applications. The library enables developers to work with raw binary data, typed arrays, encodings, and byte manipulation using an API compatible with Node.js core Buffer behavior. It is widely used in browserified applications, cryptographic tooling, networking utilities, media processing, and cross-platform JavaScript libraries that require consistent binary data operations. The project maintains compatibility with Node.js semantics while optimizing for modern browser environments and bundlers. Its implementation supports conversions between strings, arrays, ArrayBuffers, and binary representations using multiple encoding formats. buffer has become foundational infrastructure in the JavaScript ecosystem for applications requiring low-level data processing outside of native Node.js environments.
