I stumbled upon a helpful tutorial that illustrates the process of converting an Angular 2 project into a Cordova application.

Although the question initially did not reference Cordova, it is worth noting that Ionic utilizes Cordova and aims to create a mobile app. The tutorial provides detailed instructions on achieving this goal.
REQUIREMENTS
Prior to proceeding with the steps outlined below, ensure that you have successfully installed your Cordova CLI. If not, please refer to the Cordova Getting Started guide and Documentation for assistance in completing this task. Additionally, you must have already set up your Angular version 2 or higher project. This guide will be based on Angular CLI, so if you have not yet installed it, kindly visit the Angular Documentation STEPS (Tip: Remember to make a backup before executing these steps)
To begin, create a new Cordova Project using the following command: cordova create hello com.example.hello HelloWorld
2. Add the desired Cordova Building Platform:
cordova platform add [platform] Where the platform could be Android, Blackberry, or IOS
Integrate your Angular project with the newly created Cordova project by copying all folders and files (excluding the package.json file) from your Angular project's root directory to the Cordova project's root directory.
Thoroughly compare and merge the package.json files from both directories into one unified file within the Cordova project. The resulting package.json should align as illustrated below:

5. Your development project folder resides in src/. You should commence testing/building your Angular 4 app here!
- Execute ng serve to launch a dev server. Navigate to http://localhost:4200/. Any source file modifications will trigger automatic reloads within the app.
By following the aforementioned steps, you have effectively merged and converted your Angular Project into a Mobile App. To integrate the Cordova plugin, incorporate a reference to cordova.js in the html file of your angular project (src/index.html).
Please note that introducing the reference to cordova.js may generate errors when tested on a local server.
Add the Cordova Device plugin utilizing the provided command:
cordova plugin add cordova-plugin-device We are nearing completion; now let’s utilize Cordova to obtain Device information.
In your angular project, import and implement OnInit while adding the plugin callback function as outlined below.
import { Component , OnInit} from '@angular/core'; .... .... export class
AppComponent implements OnInit{ ngOnInit() {
document.addEventListener("deviceready", function() {
alert(device.platform); }, false); } } Typescript will issue a warning regarding 'device.platform' being unidentified
To rectify this concern, insert the line below directly after the import statement
declare var device; That concludes the adjustment.
Finally, proceed with building our project.
BUILDING AND RUNNING OUR APP
Revise the tag in your src/index.html to , thus granting Angular access to files in a directory path due to non-server hosting. Before initiating the build process, understand that an Angular project generates a dist folder upon successful compilation, whereas Cordova operates using the www folder for execution. Consequently, update the Angular project to compile in the www folder. To achieve this, modify the outDir property value from "dist" to "www" within .angular-cli.json/angular.json located in our root directory. Subsequently, follow through with building our Angular app – consult my prior article on HOW TO DEPLOY AND HOST AN ANGULAR 2 OR 4 PROJECT ON A SERVER should you require guidance in this area. Lastly, build and execute your Cordova project by running the following code: cordova build android|ios|[platform]
