angular-cli-esri-map

This tutorial shows you how to integrate the ArcGIS API for JavaScript, which is an enterprise geospatial API, using Angular CLI.

This repo demonstrates implementing a simple, extensible mapping component. Use this repo as a building block for adding in more advanced capabilities.

Dependencies

This repo has the following dependencies:

Build your project

If you are just getting started with Angular development, listed below are the steps for creating a simple Hello World mapping application with Angular CLI.

Once you are comfortable with the getting started steps, feel free to explore building out the app using the rest of the app.component code.

There is also a getting started video if that's easier: https://www.youtube.com/watch?v=ZEH9kOwDgx0.

Clone or download this repo

  git clone https://github.com/andygup/angular-cli-esri-map.git

Install Angular CLI and generate a new project

Make sure you have Angular CLI installed. See the instructions here: https://github.com/angular/angular-cli

Install esri-loader and the Esri TypeScript types

We need esri-loader because it is a low level service that helps load ArcGIS JavaScript API modules (v3.x or v4.x) in non-Dojo applications.

And, the ArcGIS JavaScript TypeScript type definitions can be found here.

  npm install --save esri-loader
  npm install --save @types/arcgis-js-api

Generate the scaffolding for your mapping component

  ng generate component esri-map

  # or you can also use shorthand
  ng g component esri-map

Copy the contents from the angular-cli-esri-map/src/app/esri-map folder into the esri-app/src/app/esri-map directory.

Add the following code to the bottom of the app.component.html file.

  <app-esri-map></app-esri-map>
  • In tsconfig.app.json add "types": ["arcgis-js-api"].

  • In tsconfig.spec.json add "types": ["arcgis-js-api"].

Make sure the mapping app runs

Now run the following command and you should see our mapping appear on the page.

  ng serve

Navigate to http://localhost:4200/ to see the app. The app will automatically reload if you change any of the source files. If you see the mapping app and it runs without errors then you have been successful with getting started. You can go ahead and shutdown ng serve with a Control C anytime you wish.

Build our spec and run it to make sure everything is good

Copy app.component.spec.ts into the /app directory.

  import { TestBed, async } from '@angular/core/testing';
  import { AppComponent } from './app.component';
  import { EsriMapComponent } from './esri-map/esri-map.component';

  describe('AppComponent', () => {
    beforeEach(async(() => {
      TestBed.configureTestingModule({
        declarations: [
          AppComponent,
          EsriMapComponent
        ],
      }).compileComponents();
    }));
    it('should create the app', async(() => {
      const fixture = TestBed.createComponent(AppComponent);
      const app = fixture.debugElement.componentInstance;
      expect(app).toBeTruthy();
    }));
    it(`should have as title 'app'`, async(() => {
      const fixture = TestBed.createComponent(AppComponent);
      const app = fixture.debugElement.componentInstance;
      expect(app.title).toEqual('app');
    }));
    it('should render title in a h1 tag', async(() => {
      const fixture = TestBed.createComponent(AppComponent);
      fixture.detectChanges();
      const compiled = fixture.debugElement.nativeElement;
      expect(compiled.querySelector('h1').textContent).toContain('Welcome to app!');
    }));
  });

Now lets see if the test spec passes by running:

  ng test

Bonus

Copy all app.component.* files into your new Angular CLI project's /app directory. Run ng test to make sure the code copied over correctly, then run ng serve.
