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.

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) signed and unsigned integers
32 and 64 bit floats
Varints as used in protobuf (32 and 64 bit, zig-zag)
Base64, utf8, 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.

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 has been loaded prior to bytebuffer.js.
