jpacks

Binary data packing and unpacking.

jpacks 一款强大的二进制结构编解码工具

支持复杂的结构:

e.g.

// 定义结构
jpacks.def('User', {
  age: 'uint8',
  token: jpacks.array('byte', 10),
  name: jpacks.shortString,
  note: jpacks.longString,
  contacts: jpacks.shortArray('User')
});

var user = {
  age: 6,
  token: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
  name: 'ss',
  note: '你好世界!Hello World!',
  contacts: [{
    age: 10,
    token: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
    name: 'nn',
    note: '风一样的孩子!The wind of the children!',
    contacts: [{
      age: 12,
      token: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
      name: 'zz',
      note: '圣斗士星矢!Saint Seiya!',
      contacts: []
    }]
  }, {
    age: 8,
    token: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9],
    name: 'cc',
    note: '快乐的小熊!Happy bear!',
    contacts: []
  }]
};

// 组包
var buffer = jpacks.pack('User', user);

// 解包
var user2 = jpacks.unpack('User', buffer);

console.log(JSON.stringify(user2, null, '  '));
