Bootstrapping Providers

The bootstrap process also starts the dependency injection system in Angular. We won't go over Angular's dependency injection system here - that is covered later. Instead let's take a look at an example of how to bootstrap your application with application-wide providers.

For this, we will register a service called GreeterService with the providers property of the module we are using to bootstrap the application.


import { BrowserModule }  from '@angular/platform-browser';
import { NgModule } '@angular/core';
import { AppComponent } from './app.component'
import { GreeterService } from './greeter.service';

  imports: [BrowserModule],
  providers: [GreeterService],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
export class AppModule { }
