Serializable class in ES6

Use case

Its common scenario in javscript development where we want to store js object into file/string. Js provides a powerfull built-in format JSON. However by default json format cannot contain arbitary type of object. Also restoring of original object needs little bit of work. Serializable class help you in this regard- serlizing and deserializing of javascript object in json format.

General Use

var ast = {};

class expression extends Serializable {
	factory() {
		return ast;
		}
}
class unaryExpression extends expression {
    constructor(operator, left) {
		super();
		this.argument = left;
		this.operator = operator;
    }
}

ast.expression = expression;
var str = JSON.stringify(anExpression.toJson(), null, 2);

//Deserialzing
var createdExpression = Object.create(expression.prototype);
createdExpression.fromJson(JSON.parse(str));

Alternate to subclassing

class expression {
	factory() {
		return ast;
	}
}

Serializable.mixin(expression.prototype);

With explcit attributes for serialization.

class unaryExpression extends expression {
	constructor(operator, left) {
		super();
		this.argument = left;
		this.operator = operator;
	}
	serialize(){
	    return super.serialize().add('left','operator');
	}
}
