Microsoft Application Insights JavaScript SDK - Angular Plugin

[]()

Angular Plugin for the Application Insights Javascript SDK, enables the following:

Note: Angular plugin is NOT es3 compatible

• Tracking of router changes
• Tracking uncaught exceptions

Angular Plugin for the Application Insights Javascript SDK

Getting Started

Install npm package:

npm install @microsoft/applicationinsights-angularplugin-js

Basic Usage

Set up an instance of Application Insights in the entry component in your app:

import { Component } from '@angular/core';
import { ApplicationInsights } from '@microsoft/applicationinsights-web';
import { AngularPlugin } from '@microsoft/applicationinsights-angularplugin-js';
import { Router } from '@angular/router';

//-------------------------------------------------------------------------
// Special Note: If you also want to use the ErrorService you MUST include
// either the '@microsoft/applicationinsights-web' or include the
// `@microsoft/applicationinsights-analytics-js' extension, if you don't
// then unhandled errors caught by the error service will not be sent
//-------------------------------------------------------------------------

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
    constructor(
        private router: Router
    ){
        var angularPlugin = new AngularPlugin();
        const appInsights = new ApplicationInsights({ config: {
        instrumentationKey: 'YOUR_INSTRUMENTATION_KEY_GOES_HERE',
        extensions: [angularPlugin],
        extensionConfig: {
            [angularPlugin.identifier]: { router: this.router }
        }
        } });
        appInsights.loadAppInsights();
    }
}

To track uncaught exceptions, setup ApplicationinsightsAngularpluginErrorService in app.module.ts:

Note: When using the ErrorService there is an implicit dependency on the @microsoft/applicationinsights-analytics-js extension which is also include in the that your MUST include the @microsoft/applicationinsights-web Sku, so for uncaught exceptions to be tracked your project MUST be initialized to include the analytics package otherwise unhandled errors caught by the error service will not be sent

import { ApplicationinsightsAngularpluginErrorService } from '@microsoft/applicationinsights-angularplugin-js';

//-------------------------------------------------------------------------
// Special Note: The Errorservice has an implicit dependency on the
// `@microsoft/applicationinsights-analytics-js' extension, which is included
// with the '@microsoft/applicationinsights-web' module, if the analytics 
// extension is not included during initialization of the SDK this Error Service
// will not be able to send any caught unhandled errors.
//-------------------------------------------------------------------------

@NgModule({
  ...
  providers: [
    {
      provide: ErrorHandler,
      useClass: ApplicationinsightsAngularpluginErrorService
    }
  ]
  ...
})
export class AppModule { }

To chain more custom error handlers, create custom error handlers that implement IErrorService:

import { IErrorService } from '@microsoft/applicationinsights-angularplugin-js';

export class CustomErrorHandler implements IErrorService {
    handleError(error: any) {
        ...
    }
}

And pass errorServices array through extensionConfig:

extensionConfig: {
        [angularPlugin.identifier]: {
          router: this.router,
          errorServices: [new CustomErrorHandler()]
        }
      }

Multiple Instance Setup Method

When multiple angualr plugin instance is running in the same session, their error service may overlapped each other and cause conflicts. Therefore, we allow user to use injector so that they could walk around this problem.

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
    constructor(
        private router: Router,
        injector: Injector
    ){
        var angularPlugin = new AngularPlugin(injector);
        const appInsights = new ApplicationInsights({ config: {
        instrumentationKey: 'YOUR_INSTRUMENTATION_KEY_GOES_HERE',
        extensions: [angularPlugin],
        extensionConfig: {
            [angularPlugin.identifier]: { router: this.router, useInjector: true }
        }
        } });
        appInsights.loadAppInsights();
    }
}

The way to init injector would be

const injector: Injector = Injector.create({
    providers: [
        { provide: ApplicationinsightsAngularpluginErrorService, useClass: ApplicationinsightsAngularpluginErrorService }
    ]
});

Compatibility Matrix

As part of updating to support ApplicationInsights 3.x we will be bumping the major version number of this extension to match the major version of the supported Angular version (which will be v14.x for the first release).

Additionally, as part of this change the existing v3.x extension has been moved into the release3.x branch

Previous releases where from the ApplicationInsights-JS repo with archived angularplugin-legacy Branch and previous Release Notes

Note

Angular plugin is using newer version of typescript, make sure to build and test before you create a pull request. Navigate to the root folder of Angular plugin, under /applicationinsights-angularplugin-js:

npm install
npm run build
npm run test

Testing

npm run test will run the tests once and exit

npm run watch will run the tests and watch for changes
