Zipack.JS

Live demo: https://zipack.github.io/#demo

Zipack.js is an official encoder/decoder of Zipack format using JavaScript with no dependencies.

Install

npm install zipack-official

import zipack from 'zipack.js'

zipack {
    serialize(Object)  // code
    parse(Buffer)      // decode
}

Default JS Objects

the types zipack support by default:

• number
• string
• boolean
• Array
• Object (enumerable)
• ArrayBuffer
• null

Example

let obj = {
    number: 123,
    float: 3.14,
    string: 'hello world',
    boolean: true,
    null: null,
    list: [1, 2, 3],
    map: {negative: -123},
    buffer: (new Uint8Array([1,2,3])).buffer
}

// JS Object ---> Uint8Array
let buffer = zipack.serialize(obj)

// Uint8Array ---> JS Object
obj = zipack.parse(buffer)

[Object].prototype.zipack

like toJSON() in JavaScript, define zipack() for specific Objects, which outputs the types zipack support. for example, Date could be stored as number:

• function：zipack
• input：none
• output：default types or Uint8Array

Date.prototype.zipack = function () {
  return this.getTime();
};

Extension (experimental)

register callback(params: Uint8Array) to parse zipack, meanwhile, define zipack() returning Uint8Array to serialize. See extend-demo.js.
