Official Sentry SDK for Angular with Ivy Compatibility

Angular Version Compatibility

This SDK officially supports Angular 12 to 16 with Angular's new rendering engine, Ivy.

If you're using Angular 10, 11 or a newer Angular version with View Engine instead of Ivy, please use @sentry/angular.

If you're using an older version of Angular and experience problems with the Angular SDK, we recommend downgrading the SDK to version 6.x. Please note that we don't provide any support for Angular versions below 10.

General

This package is a wrapper around @sentry/browser, with added functionality related to Angular. All methods available in @sentry/browser can be imported from @sentry/angular-ivy.

To use this SDK, call Sentry.init(options) before you bootstrap your Angular application.

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { init } from '@sentry/angular-ivy';

import { AppModule } from './app/app.module';

init({
  dsn: '__DSN__',
  // ...
});

// ...

enableProdMode();
platformBrowserDynamic()
  .bootstrapModule(AppModule)
  .then(success => console.log(`Bootstrap success`))
  .catch(err => console.error(err));
Copy

ErrorHandler

@sentry/angular-ivy exports a function to instantiate an ErrorHandler provider that will automatically send Javascript errors captured by the Angular's error handler.

import { NgModule, ErrorHandler } from '@angular/core';
import { createErrorHandler } from '@sentry/angular-ivy';

@NgModule({
  // ...
  providers: [
    {
      provide: ErrorHandler,
      useValue: createErrorHandler({
        showDialog: true,
      }),
    },
  ],
  // ...
})
export class AppModule {}
Copy

Additionally, createErrorHandler accepts a set of options that allows you to configure its behavior. For more details see ErrorHandlerOptions interface in src/errorhandler.ts.

Tracing

@sentry/angular-ivy exports a Trace Service, Directive and Decorators that leverage the tracing features to add Angular-related spans to transactions. If tracing is not enabled, this functionality will not work. The SDK's TraceService itself tracks route changes and durations, while directive and decorators are tracking components initializations.

Install

Registering a Trace Service is a 3-step process.

1. Register and configure the BrowserTracing integration, including custom Angular routing instrumentation:

import { init, instrumentAngularRouting, BrowserTracing } from '@sentry/angular-ivy';

init({
  dsn: '__DSN__',
  integrations: [
    new BrowserTracing({
      tracingOrigins: ['localhost', 'https://yourserver.io/api'],
      routingInstrumentation: instrumentAngularRouting,
    }),
  ],
  tracesSampleRate: 1,
});
Copy

2. Register SentryTrace as a provider in Angular's DI system, with a Router as its dependency:

import { NgModule } from '@angular/core';
import { Router } from '@angular/router';
import { TraceService } from '@sentry/angular-ivy';

@NgModule({
  // ...
  providers: [
    {
      provide: TraceService,
      deps: [Router],
    },
  ],
  // ...
})
export class AppModule {}
Copy

3. Either require the TraceService from inside AppModule or use APP_INITIALIZER to force-instantiate Tracing.

@NgModule({
  // ...
})
export class AppModule {
  constructor(trace: TraceService) {}
}
Copy

or

import { APP_INITIALIZER } from '@angular/core';

@NgModule({
  // ...
  providers: [
    {
      provide: APP_INITIALIZER,
      useFactory: () => () => {},
      deps: [TraceService],
      multi: true,
    },
  ],
  // ...
})
export class AppModule {}
Copy

Use

To track Angular components as part of your transactions, you have 3 options.

TraceDirective: used to track a duration between OnInit and AfterViewInit lifecycle hooks in template:

import { TraceModule } from '@sentry/angular-ivy';

@NgModule({
  // ...
  imports: [TraceModule],
  // ...
})
export class AppModule {}
Copy

Then inside your components template (keep in mind that directive name attribute is required):

<app-header trace="header"></app-header>
<articles-list trace="articles-list"></articles-list>
<app-footer trace="footer"></app-footer>
Copy

TraceClassDecorator: used to track a duration between OnInit and AfterViewInit lifecycle hooks in components:

import { Component } from '@angular/core';
import { TraceClassDecorator } from '@sentry/angular-ivy';

@Component({
  selector: 'layout-header',
  templateUrl: './header.component.html',
})
@TraceClassDecorator()
export class HeaderComponent {
  // ...
}
Copy

TraceMethodDecorator: used to track a specific lifecycle hooks as point-in-time spans in components:

import { Component, OnInit } from '@angular/core';
import { TraceMethodDecorator } from '@sentry/angular-ivy';

@Component({
  selector: 'app-footer',
  templateUrl: './footer.component.html',
})
export class FooterComponent implements OnInit {
  @TraceMethodDecorator()
  ngOnInit() {}
}
Copy

You can also add your own custom spans by attaching them to the current active transaction using getActiveTransaction helper. For example, if you'd like to track the duration of Angular boostraping process, you can do it as follows:

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { init, getActiveTransaction } from '@sentry/angular-ivy';

import { AppModule } from './app/app.module';

// ...

const activeTransaction = getActiveTransaction();
const boostrapSpan =
  activeTransaction &&
  activeTransaction.startChild({
    description: 'platform-browser-dynamic',
    op: 'ui.angular.bootstrap',
  });

platformBrowserDynamic()
  .bootstrapModule(AppModule)
  .then(() => console.log(`Bootstrap success`))
  .catch(err => console.error(err));
  .finally(() => {
    if (bootstrapSpan) {
      boostrapSpan.finish();
    }
  })
Copy
