Quick serializer

Quick serializer is a library that allows you to quickly serialize and deserialize classes to and from JSON representations. This JSON can then be stored somewhere like localstorage.

Installation

To install quick serializer use NPM:

npm install quick-serializer

Usage

To get started, add the Serializable decorator to the class you want to serialize:

import { Serializable } from "quick-serializer";

@Serializable("Person")
class Person {
    name: string;

    constructor(name: string) {
        this.name = name;
    }
}

You need to give it a name and make sure it's unique. You can then serialize it to JSON using the serializer:

import { Serializer } from "quick-serializer";

let person = new Person();

let serializer = new Serializer();
let json = await serializer.serialize(person);

To then deserialize it back to class objects, you need to pass the class constructor along with the JSON:

import { Serializer } from "quick-serializer";

let serializer = new Serializer();
let deserializedPerson = await serializer.deserialize(Person, person);

Nested classes and inheritance

Usually classes have objects from other classes attached to them, and they might also inherit from other classes. For example:

class Person {
    name: string;
    pet: Pet;

    constructor(name: string) {
        this.name = name;
    }
}

class Pet {
    name: string;
    owner: Person;
}

class Cat extends Pet {
    isCute: boolean;
}

In this case we will first add the Serializable decorator to all classes, but in addition to the label we also add the dependencies of that class:

import { Serializable } from "quick-serializer";

@Serializable("Person", () => [Pet])
class Person {
    name: string;
    pet: Pet;

    constructor(name: string) {
        this.name = name;
    }
}

@Serializable("Pet", () => [Person])
class Pet {
    name: string;
    owner: Person;
}

@Serializable("Cat")
class Cat extends Pet {
    isCute: boolean;
}

This way, quick serializer knows where to find the classes it needs when it's deserializing back from JSON.
