pypacker is a binary packer and unpacker inspired by Python's struct
library for node.js.
Currently, it packs/unpacks to and from a Buffer object. When unpacking,
an array is returned with the requested values.
Interfacing is exactly the same as the Python struct python class except there are no 8-byte integers.
npm install pypacker
Packer = require('pypacker'); var unpack_array = new Packer('>H') .unpack(new Buffer([0x00, 0x01])); // unpack_array will be an array containing  var packed_buffer = new Packer('>H') .pack(1); // packed_buffer will be a Buffer of length 2 containing 00 01
