## Installation

Install & save the library to your package.json:

```bash
$ npm i -S @markpieszak/ng-application-insights

# yarn

$ yarn add @markpieszak/ng-application-insights
```

---

### AppModule Setup

Now add ApplicationInsightsModule to your Angular Root `AppModule`:

```typescript
// 1) Import the Application Insights module and the service provider
import { ApplicationInsightsModule, AppInsightsService } from '@markpieszak/ng-application-insights';

@NgModule({
  imports: [
    // 2) Add the Module to your imports
    ApplicationInsightsModule.forRoot({
      instrumentationKey: 'Your-Application-Insights-instrumentationKey'
    })
  ],
  providers: [ 
     // 3) Add AppInsightsService to your providers list
     AppInsightsService
  ]
})
export class YourRootModule { }
```

### What if you don't know your instrumentationKey right away?

```typescript
// Use instrumentationKeySetLater
ApplicationInsightsModule.forRoot({
  instrumentationKeySetLater: true // <--
})

// Then later in your Application somewhere
constructor(
  private appInsightsService: AppInsightsService
) {
  appInsightsService.config = {
    instrumentationKey: __env.APPINSIGHTS_INSTRUMENTATIONKEY // <-- set it later sometime
  }
  // then make sure to initialize and start-up app insights
  appInsightsService.init();
}

```

## Usage

Through out your application you can now use the AppInsightsService class to fire off AppInsights functionality.

```typescript
import { AppInsightsService } from '@markpieszak/ng-application-insights';

export class ShoppingCartComponent {
  public cart: [];
  constructor(private appInsightsService: AppInsightsService) {}

saveCart(user) {
    // MOCK Example of sending a trackEvent()
    // Saving some sample user & cart product data
    this.appInsightsService.trackEvent('ShoppingCart Saved', { 'user': user.id, 'cart': cart.id });
  }
}
```

## Usage with Aspnetcore-Angular2-Universal repo or JavaScriptServices ( apps w/ Server-side rendering )

> ie: <https://github.com/TrilonIO/aspnetcore-angular-universal>

First, make sure you are only importing the library & the server within the **browser-app.module** NgModule (do not share it within a common one, as the server isn't able to use this library during it's server-renders).

Secondly, make sure you are calling the `injector` to get AppInsightsService during **ngOnInit**:

```typescript
export class HomeComponent implements OnInit {

private AIService: AppInsightsService;
  private isBrowser: boolean;

constructor(@Inject(PLATFORM_ID) private platformId, private injector: Injector) {
    this.isBrowser = isPlatformBrowser(this.platformId);
  }

ngOnInit() { // <-- 
    if (this.isBrowser) { // <-- only run if isBrowser
      this.AIService = <AppInsightsService>this.injector.get(AppInsightsService); // <-- using the Injector, get the Service
      this.AIService.trackEvent('Testing', { 'user': 'me' });
    } 
  }
}
```

## API

You can see a list of the API here: <https://github.com/Microsoft/ApplicationInsights-JS/blob/master/API-reference.md#class-appinsights>

```typescript
AppInsightsService.trackEvent()
AppInsightsService.startTrackEvent()
AppInsightsService.stopTrackEvent()
AppInsightsService.trackPageView()
AppInsightsService.startTrackPage()
AppInsightsService.stopTrackPage()
AppInsightsService.trackMetric()
AppInsightsService.trackException()
AppInsightsService.trackTrace()
AppInsightsService.trackDependency()
AppInsightsService.flush()
AppInsightsService.setAuthenticatedUserContext()
AppInsightsService.clearAuthenticatedUserContext()
```
