dtobase

This library will provide you 2 tools:

• DtoConversion: to help you convert from ViewModel to Dto with strictly typed
• MemStore: in memory storage, to help you register your objects and later use in other part of your code

class DtoClass extends BaseDto{
    constructor() {
        super();
    }

    static get dtoType() {
        return 'myDtoType';
    }

    static get dtoSubType() {
        return 'myDtoSubType';
    }
}

const instance = new MemStore();

instance.registerDto('myDtoType', 'myDtoSubType', DtoClass); // Explicity register dto

instance.registerDto('myDtoType', DtoClass); // Explicity register dto with subtype = ''

instance.registerDto(DtoClass); // Implicit register Dto from it class

Sample dto

'use strict';

class MyDto extends BaseDto {
    constructor() {
        super(false);
