Of course this is just an example. And the goal here is to show how you can create a factory of objects (even if each object has an unique relevant set of information).

factory.pattern.ts

/**
 * In this folder (creational.patterns/factory.pattern/) you will find an 
 * example implementation of the Factory design pattern. This means that 
 * you will see that things were created without using the word 'new'.

class iPhoneFamily {
    public version: string;
    public suportedIOs: number;
    public initialPrice: number;
    public headphoneConnectorType: string;

    constructor(props: any) {
        this.version = props.version;
        this.suportedIOs = props.suportedIOs;
        this.headphoneConnectorType = props.headphoneConnectorType;
        this.initialPrice = props.initialPrice;
    }
}

class PixelFamily {
    version: string;
    suportedAndroid: number;
    initialPrice: number;

    constructor(props: any) {
        this.version = props.version;
        this.suportedAndroid = props.suportedAndroid;
        this.initialPrice = props.initialPrice;
    }
}

class GalaxyFamily {
    version: string;
    suportedAndroid: number;
    kilotons: number;
    initialPrice: number;

    constructor(props: any) {
        this.version = props.version;
        this.suportedAndroid = props.suportedAndroid;
        this.kilotons = props.kilotons;
        this.initialPrice = props.initialPrice;

export class SmartphoneFactory {
    public static getSmartphone(model: string, props: any) {
        let models = new Map();
        models.set('iPhoneFamily', iPhoneFamily);
        models.set('PixelFamily', PixelFamily);
        models.set('GalaxyFamily', GalaxyFamily);
        const createInstanceOf = models.get(model)
        return new createInstanceOf(props);
    }
}

A way to use is:

import { SmartphoneFactory } from './design.patterns/creational.patterns/factory.pattern/factory.pattern'

const iPhoneXR = SmartphoneFactory.getSmartphone('iPhoneFamily', {version: 'iPhone XR', suportedIOs: 13, headphoneConnectorType: "Lightning", initialPrice: 999.90});
const pixelXL = SmartphoneFactory.getSmartphone('PixelFamily', {version: 'Pixel XL', suportedAndroid: 7.1, initialPrice: 600});
const galaxyNote7 = SmartphoneFactory.getSmartphone('GalaxyFamily', {version: 'Galaxy Note 7', suportedAndroid: 6, kilotons: 7, initialPrice: 30});
