implode

implode

This library implodes complex Javascript objects preparing them to be serialized and later on deserialized. Supported structures:

• multiple references to the same object
• circular references
• functions (non-native and non-closure functions)
• constructors
• constructor instances

{
  "name": "implode",
  "version": "1.1.1"
}

Usage

var implode    = require('implode')
var serialized = JSON.stringify(implode(obj)) // serialize
var recovered  = implode.recover(JSON.parse(serialized)) // deserialize

Constructors

To use constructors, e.g.:

var User = function(id, name) {
  this.id = id
  this.name = name
  
  // when being recovered, this constructor is called without arguments,
  // therefore the bootstrap logic is moved to a seperate method 
  this.init()
}

User.prototype.init = function() {
  this.excerpt = this.id + '-' + this.name
}

User.prototype.$deserialize = function(obj) {
  // this hook allows to postprocess the object when it got recovered
  obj.init()
  return obj
}

User.prototype.$serialize = function() {
  // this hook allows to preprocess the object for the implode process
  return this
}

... they have to be registered:

implode.register(
  'User', // unique identifier
  User, // the constructor
  ['id', 'name'] // a whitelist of properties
)
