js_serializer

A serializer for js written in TypeScript which serializes and deserializes data and restores class instances upon deserialization.

Can be used both in the browser and in Node.JS.

Example

import Serializer from 'js_serializer';

class Test {
    _a = null;
    _b = null;


    constructor(a, b) {
        this.a = a;
        this.b = b;
    }

    get a() {
        return this._a;
    }

    set a(value) {
        this._a = value;
    }

    get b() {
        return this._b;
    }

    set b(value) {
        this._b = value;
    }

    getAB() {
        return this.a + ' - ' + this.b;
    }
}

const getRandomInt = (max) => {
    return Math.floor(Math.random() * max);
};

const getRandomInstance = () => {
    return new Test(getRandomInt(100), getRandomInt(100));
};

const testSet = {
    test1: getRandomInstance(),
    test2: [
        getRandomInstance(),
        getRandomInstance(),
        getRandomInstance()
    ],
    test3: [
        {
            test3_1: getRandomInstance()
        }
    ]
};

// Creating the serializer instance.

/**
    You'll have to specify all class constructors here that may be serialized.
    Basically, the serializer adds a field to the json (per class),
    called "__restoreClass", which will be used to restore the class.
 
    Only necessary on deserialization, as this will be used to
    re-instantiate the serialized classes.
 */
const serializer = new Serializer({
    Test
});


console.log('BEFORE', testSet);

const testResult = serializer.deserialize(
    serializer.serialize(testSet)
);

console.log('AFTER', testResult);

console.log('METHOD TEST testResult.test2[1]', testResult.test2[1].getAB());
