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 [1]

var packed_buffer = new Packer('>H')
// packed_buffer will be a Buffer of length 2 containing 00 01
