Setting up a boilerplate for Angular 2


I guess we all say amen to the following quote:

“The Only Thing That Is Constant Is Change” – Heraclitus

Working with XPages / IBM Notes you get scare-mongered a couple times a year thatthe whole thing is dead. With the Java vs JavaScript deathmatch not decided yet as ICS developer you might wonder on what train to jump next.

In the past I have been looking at Angular but never took it to the next level. With Angular 2 recently official released the cards might be different this time. Just look at the job vacancy sites and Angular specialists are searched after everywhere.

So I took a course Angular 2 and now I am migrating an XPages app to Angular 2 to see if the love is both directions.

Angular 2 boilerplate

A big difference with the previous version of Angular is the preparation. Angular 2 requires some sort of boilerplate, which I will describe how to build in this post.


I will be using Domino as the HTTP server, since my data still resides in NSF. So for now my Angular app will live in the WebContent folder, so that is the working directory of my application. For ease of working I have setup a Github project. Added an ODP folder and synched my NSF with that.

In the WebContent folder in my ODP I will create the following documents:

  • tsconfig.json
  • typings.json
  • package.json
  • app/app.component.ts
  • app/main.ts
  • index.html

If you want you can just download a quickstart somewhere.


Create this file in the root of your project. In my course Typescript is used, but you could also script in Angular with JavaScript of course.

tsconfig defines the compiler configuration, here we say that our target code is JavaScript.

“compilerOptions”: {
“target” : “es5”,
“module” : “system”,
“moduleResolution” : “node”,
“sourceMap” : true,
“emitDecoratorMetadata” : true,
“experimentalDecorators”: true,
“removeComments” : false,
“noImplicitAny” : false
“exclude” : [


Also place this file in the root of your project. In this file you define the Typescript declarations. It turns out that the Typescript compiler does not recognize several libraries…

“ambientDependencies”: {
“es6-shim”: “github:DefinitelyTyped/DefinitelyTyped/es6-shim/es6-shim.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd”,
“jasmine” : “github:DefinitelyTyped/DefinitelyTyped/jasmine/jasmine.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd”


This file will also be stored in the root of the project. In this file all dependencies and it’s versions are registered, which we will install with NPM.



An Angular 2 app needs at minimum 1 component, the root component. Components are the basic building blocks of Angular applications. A component controls a portion of the screen—a view—through its associated template.

import {Component} from ‘angular2/core’;

selector: ‘hello-world’,
template: ‘<h1>Hello World</h1>’
export class AppComponent {
// … here we will add our logic later

So first you define a component, and then you make it available for export so you can import it into the application.


This file is the bootstrapper in our app. Since our boilerplate is simple it does not contain so much yet:

import {bootstrap} from ‘angular2/platform/browser’
import {AppComponent} from ‘./app.component’


Note: At this moment we do not have declared to use any module so we do not have to create an app/app.module.ts file.


The index file contains out of 2 sections, the first is the header, the other one the body. The header can be divided into 3 steps:

  • add styling
  • load the libraries
  • configure our main.js


The second part is the body content of the HTML file:



We’re done!

With this in place we have our boilerplate in place. Run “NPM install” and thereafter “NPM start” or open the index.html file on your domino server (after you have synced the files back to the NSF (this might take a while).

Also notice how the Typescript files are compiled to JavaScript files:


And finally “surprise-surprise” the result:



Starting developing with Angular 2 is a bit different in comparison with version. Backward compatibility has always been strong for IBM Notes/Domino.

TypeScript is another opportunity for developers. I intend to blog more about my Angular journey and we’ll see how long the love will last 🙂
