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.
