Getting Started is Simple

Grab the Sentry Angular SDK:

Click to Copy

# for Angular 14 or newer:
npm install @sentry/angular
# for Angular 12 and 13:
npm install @sentry/angular-ivy@7

Configure your DSN:

Click to Copy

import { platformBrowserDynamic } from "@angular/platform-browser-dynamic";
import { NgModule, ErrorHandler } from "@angular/core";
import * as Sentry from "@sentry/angular";

Sentry.init({
  dsn: "https://<key>@sentry.io/<project>",
  // This enables automatic instrumentation (highly recommended),
  // but is not necessary for purely manual usage
  // If you only want to use custom instrumentation:
  // * Remove the BrowserTracing integration
  // * add Sentry.addTracingExtensions() above your Sentry.init() call
  integrations: [Sentry.browserTracingIntegration()],

  // We recommend adjusting this value in production, or using tracesSampler
  // for finer control
  tracesSampleRate: 1.0,

  // Set tracePropagationTargets to control for which URLs distributed tracing should be enabled
  tracePropagationTargets: ['localhost', /^https://yourserver.io/api/],
});

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

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

Angular Performance Monitoring

Quickly identify performance issues and view full end-to-end distributed trace to see the exact poor-performing API call and surface any related Angular errors. Improve Angular performance with max efficiency, not max effort.

Angular Error Monitoring With Complete Stack Traces

See the error and Angular stack trace previously only visible in your user’s debug console. Apply source maps automatically to convert minified, compiled, or transpiled code back to its original form. Keep your Angular source maps private by uploading them directly to Sentry.

Issues, replayed

Get to the root cause of an error or latency issue faster with context like DOM events, console logs, and network calls within one visual replay on your web application.

Fill In The Blanks About Angular Errors

See what the app was doing when the Angular error occurred: user interactions, AJAX requests, console log messages, and more. Learn in which version a bug first appeared, merge duplicates, and know if things regress in a future release

“By correlating Sentry issues to our dev cycle, we can spot where problems begin and how to fix the source.”

Record environment and usage details so you can recreate bugs down to the browser version, OS, and query parameters specific to your app.

Sentry’s tag distribution graph makes it easy to isolate and prioritize any Angular error by seeing how often it occurs in context.

Find answers to key questions: How actionable is this error?Was the bug browser or OS specific?

You can’t afford to put JavaScript monitoring on the backburner.

Even a one-second delay in loading results in a 7% reduction in conversions.

Forty percent of customers abandon a website that takes longer than three seconds to load.

The average cost of downtime is $5,600 per minute — or $300,000 per hour.

FAQs

Traditional logging provides you with a trail of events. Some of those events are errors, but many times they’re simply informational. Sentry is fundamentally different because we focus on exceptions, or in other words, we capture application crashes. We discuss in more detail here and on our blog.

Sentry supports every major frontend language, framework, and library. You can browse each of them here.

You can get started for free. Pricing depends on the number of monthly events, transactions, and attachments that you send Sentry. For more details, visit our pricing page.

Sentry doesn’t impact a web site’s performance.

If you look at the configuration options for when you initialize Sentry in your code, you’ll see there’s nothing regarding minimizing its impact on your app’s performance. This is because our team of SDK engineers already developed Sentry with this in mind.

Sentry is a listener/handler for errors that asynchronously sends out the error/event to Sentry.io. This is non-blocking. The error/event only goes out if this is an error.

Global handlers have almost no impact as well, as they are native APIs provided by the browsers.
