Angular Version Compatibility

This SDK officially supports Angular 14 to 20.

If you're using an older Angular version please check the compatibility table in the docs.

If you're using an older version of Angular and experience problems with the Angular SDK, we recommend downgrading the SDK to version 7.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.

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

import { bootstrapApplication } from '@angular/platform-browser';
import { init } from '@sentry/angular';

import { AppComponent } from './app/app.component';

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

bootstrapApplication(AppComponent, appConfig);

ErrorHandler

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

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

export const appConfig: ApplicationConfig = {
  providers: [
    {
      provide: ErrorHandler,
      useValue: createErrorHandler({
        showDialog: true,
      }),
    },
  ],
};

// Or using an old module approach:
@NgModule({
  // ...
  providers: [
    {
      provide: ErrorHandler,
      useValue: createErrorHandler({
        showDialog: true,
      }),
    },
  ],
  // ...
})
export class AppModule {}

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 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.

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

import { init, browserTracingIntegration } from '@sentry/angular';

init({
  dsn: '__DSN__',
  integrations: [browserTracingIntegration()],
  tracePropagationTargets: ['localhost', 'https://yourserver.io/api'],
  tracesSampleRate: 1,
});

• Inject the TraceService in the APP_INITIALIZER:

import { ApplicationConfig, APP_INITIALIZER, provideAppInitializer } from '@angular/core';

export const appConfig: ApplicationConfig = {
  providers: [
    {
      provide: APP_INITIALIZER,
      useFactory: () => () => {},
      deps: [TraceService],
      multi: true,
    },

    // Starting with Angular 19, we can use `provideAppInitializer`
    // instead of directly providing `APP_INITIALIZER` (deprecated):
    provideAppInitializer(() => inject(TraceService)),
  ],
};

// Or using an old module approach:
@NgModule({
  // ...
  providers: [
    {
      provide: APP_INITIALIZER,
      useFactory: () => () => {},
      deps: [TraceService],
      multi: true,
    },

    // Starting with Angular 19, we can use `provideAppInitializer`
    // instead of directly providing `APP_INITIALIZER` (deprecated):
    provideAppInitializer(() => inject(TraceService)),
  ],
  // ...
})
export class AppModule {}

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';

@Component({
  selector: 'some-component',
  imports: [TraceModule],
  // ...
})
export class SomeComponentThatUsesTraceDirective {}

Then, inside your component's template (keep in mind that the directive's name attribute is required):

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

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

import { Component } from '@angular/core';
import { TraceClass } from '@sentry/angular';

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

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

import { Component, OnInit } from '@angular/core';
import { TraceMethod } from '@sentry/angular';

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

You can also add your own custom spans via startSpan(). 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, startSpan } from '@sentry/angular';

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

// ...
startSpan(
  {
    name: 'platform-browser-dynamic',
    op: 'ui.angular.bootstrap',
  },
  async () => {
    await platformBrowserDynamic().bootstrapModule(AppModule);
  },
);
