The swiss army knife for binary data in JavaScript.

Package Exports

  • bytebuffer

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (bytebuffer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ByteBuffer.js - The swiss army knife for binary data in JavaScript.

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.

Build Status Donate

What can it do?

  • 8, 16, 32 and 64 bit signed and unsigned integers
  • 32 and 64 bit floats
  • Big and little endianness
  • Varints as used in protobuf (32 and 64 bit, zig-zag)
  • Base64, binary, debug, hex and utf8 encodings
  • Handy string and debugging utilities
  • 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.

API

Downloads

Support for IE<10, FF<15, Chrome<9 etc.

  • Requires working ArrayBuffer & DataView implementations (i.e. use a polyfill)
