![bytebuffer.js - The swiss army knife for binary data in JavaScript.](https://raw.github.com/dcodeIO/bytebuffer.js/master/bytebuffer.png) ====================================== A fast and complete ByteBuffer implementation using either ArrayBuffers in the browser or node Buffers under node.js, generated from a single source tree through [MetaScript](https://github.com/dcodeIO/MetaScript). [![Build Status](https://travis-ci.org/dcodeIO/bytebuffer.js.svg?branch=master)](https://travis-ci.org/dcodeIO/bytebuffer.js) [![Donate](https://raw.githubusercontent.com/dcodeIO/bytebuffer.js/master/donate.png)](https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=dcode%40dcode.io&item_name=%3C3%20bytebuffer.js) Features -------- * Three API-compatible versions: * **bytebuffer**   Backing buffer: ArrayBuffer, Accessor: Uint8Array * **bytebuffer-dataview**   Backing buffer: ArrayBuffer, Accessor: DataView * **bytebuffer-node**   Backing buffer / Accessor: node Buffer * 8, 16, 32 and 64 bit (through [long.js](https://github.com/dcodeIO/long.js)) signed and unsigned integers * 32 and 64 bit floats * Varints as used in protobuf (32 and 64 bit, zig-zag) * [Base64](https://github.com/dcodeIO/lxiv), [utf8](https://github.com/dcodeIO/utfx), binary, hex and debug encodings * Handy string and debugging utilities * Big and little endianness * Relative and absolute zero-copy operations wherever possible * Transparent resizing when using unknown-length data * Chaining of all operations that do not return a specific value * Slicing, appending, prepending, reversing, flip, mark, reset, etc. Usage ----- The library is compatible with CommonJS and AMD loaders and is exposed globally as `dcodeIO.ByteBuffer` if neither is available. ```javascript var ByteBuffer = require("bytebuffer"); var bb = new ByteBuffer() .writeIString("Hello world!") .flip(); console.log(bb.readIString()+" from bytebuffer.js"); ``` In the browser, 64 bit integer support is optional and present only if [Long.js](https://github.com/dcodeIO/long.js) has been loaded prior to bytebuffer.js.
