Introduction

TS-Serializer Core is a library to manage serialization and deserialization in a Typescript program. It use decorator to configure serialization and deserialization.

Installation

For installing core in Typescript Project with NPM, just run this command :

npm i ts-serializer-core

How to use

Serializer

To use the serializer, you just have to instantiate an object of type Serializer.

import {Serializer} from 'ts-serializer-core';

const serializer: Serializer = new Serialize();
...

The serializer accept two arguments :

Deserializer

To use the deserializer, you just have to instantiate an object of type Deserializer.

import {Deserializer} from 'ts-deserializer-core';

const deserializer: Deserializer = new Deserialize();
...

The deserializer accept one argument :

Serialization/Deserialization configuration

In this example, we configure models with simple and complex object/array type :

import {JsonProperty} from 'ts-deserializer-core';

export class User {

    @JsonProperty('identifier')
    public id: number;

    @JsonProperty('lastName')
    public lastName: string;

    @JsonProperty('firstName')
    public firstName: string;
}

export class Hero extends User {

    @JsonProperty({name: 'weapons', type: Weapon})
    public weapons: Weapon[];

    @JsonProperty({name: 'animal', type: Animal})
    public animal: Animal;

    @JsonProperty('tags')
    public tags: string[];
}

export class Animal {

    @JsonProperty('id')
    public id: number;

    @JsonProperty('name')
    public name: string;

    public pv: number;
}

export class Weapon {

    @JsonProperty('id')
    public id: number;

    @JsonProperty('name')
    public name: string;
}

To use this configuration, we can run this code example :

const hero: Hero = new Hero();
hero.id = 1;
hero.firstName = 'Thomas';
hero.lastName = 'Nisole';
hero.nickName = 'Tom';
hero.animal = new Animal();
hero.animal.id = 2;
hero.animal.name = 'Patrick';
hero.animal.pv = 51;
hero.tags = ['tag1', 'tag2'];

const weapon1 = new Weapon();
weapon1.id = 3;
weapon1.name = 'Sword';

const weapon2 = new Weapon();
weapon2.id = 4;
weapon2.name = 'shield';

hero.weapons = [weapon1, weapon2];

const serializer: Serializer = new Serializer(serializerConfiguration);
console.log(serializer.serialize(hero));

The result is :

{
    "identifier": 1,
    "firstName": "Thomas",
    "lastName": "Nisole",
    "animal": { "id": 2, "name": "Patrick" },
    "tags": [ "tag1", "tag2" ],
    "weapons": [
        {
            "id": 3,
            "name": "Sword"
        },
        {
            "id": 4,
            "name": "shield"
        }
    ]
}

API

JsonProperty

JsonProperty is a decorator for class attribute. It is use to configure the serialization/deserialization process. You can use all of this next attributes or just a string.

Converter

Converter is an interface use to make custom converter.

DateConverter

DateConverter is a class used to convert DateTime object to ISO date string.
