Serializable Class

serializable-class is a lightweight library that handles class serialization and deserialization.

Installation

npm install --save serializable-class

Quick Start

const SerializableClass = require('serializable-class')
let object = new SerializableClass()

Serialization

let object = new SerializableClass()
object.value = 10
object.serialize() // { _class: 'SerializableClass', value: 10 }

Deserialization

let object = new SerializableClass()
object.value = 10
let data = object.serialize()
let deserializedObject = SerializableClass.deserialize(data) // SerializableClass { value: 10 }

Extending Classes

Extending the SerializableClass class is easy. Just be sure to register the extended class after it has been defined.

class Subclass extends SerializableClass {}
SerializableClass.register(Subclass)
let object = new SerializableClass()
object.subclass = new Subclass()
let data = object.serialize() // {_class: 'SerializableClass', subclass: { _class: 'Subclass' } }
let deserializedObject = SerializableClass.deserialize(data) // SerializableClass { subclass: Subclass {} }

It is not necessary to call deserialize on the extended class that you want to be returned. The class returned will always match the _class of the serialized object that is provided.

class Subclass extends SerializableClass {}
SerializableClass.register(Subclass)
let object = new Subclass()
object.value = 10
let data = object.serialize() // { _class: 'Subclass', value: 10 }
let deserializedObject = SerializableClass.deserialize(data) // Subclass { value: 10}

Hooks

There are four hooks available — _preSerialize, _postSerialize, _preDeserialize, _postDeserialize — which are called at the respective steps in a class's serialization and deserialization.
