angular2-esri-loader instructions
  1. Clone the starter repo AngularClass/angular2-webpack-starter and then cd into your local directory.

  2. Install angular2-esri-loader

npm install angular2-esri-loader --save

# optional, if you want type support in your IDE for JSAPI 4.x
npm install @types/arcgis-js-api --save-dev
  1. Add the following import statements to the bottom of your application's module:
import { EsriLoaderService } from 'angular2-esri-loader';
import { EsriMapComponent } from './esri';
  1. Add the following to your application's declarations (you'll make a new mapping component soon):
EsriMapComponent
  1. Add the following to your application's providers to register angular2-esri-loader's EsriLoaderService:
EsriLoaderService
  1. Create a new component that uses the EsriLoaderService to show a map
  1. Optional: Create a new route in your application if needed
import { Routes } from '@angular/router';
import { HomeComponent } from './home';
import { AboutComponent } from './about';
import { EsriMapComponent } from './esri';
import { NoContentComponent } from './no-content';
import { DataResolver } from './app.resolver';
export const ROUTES: Routes = [
{ path: '', component: HomeComponent },
{ path: 'home', component: HomeComponent },
{ path: 'about', component: AboutComponent },
{ path: 'esri', component: EsriMapComponent },
{ path: 'detail', loadChildren: './+detail#DetailModule'},
{ path: 'barrel', loadChildren: './+barrel#BarrelModule'},
{ path: '**', component: NoContentComponent },
];
