Resolve JavaScript errors with max efficiency, not max effort. Get actionable insights to resolve JavaScript performance issues with the ability to track, debug, and resolve JavaScript errors across platforms.
Grab the Sentry JavaScript SDK:
<script src="https://browser.sentry-cdn.com/8.42.0/bundle.min.js"></script>
Configure your DSN:
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/], });
Check our documentation for the latest instructions.
See all platformsQuickly identify JavaScript performance issues before they become downtime. View the entire end-to-end distributed trace to see the exact, poor-performing API call and surface any related errors.
See the error and JavaScript 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 JavaScript source maps private by uploading them directly to Sentry.
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.
Check out Session ReplaySee what the app was doing when the JavaScript error occurred: user interactions with component names, AJAX requests, console log messages and more. When frontend errors happen, Sentry can prompt users for feedback so you can compare their experiences to the data.
Quickly isolate Code Coverage for JavaScript bugs to see where testing could help fix the bug before release with our Codecov integration.
Learn More About Codecov by SentryRecord environment and usage details so you can recreate bugs down to the browser version, OS, and query parameters specific to the session.
Sentry’s tag distribution graph also makes it easy to isolate and prioritize any JavaScript error by seeing how often it occurs in context.
Answer the most important questions: Was the bug browser or OS specific? Firefox or Safari?
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.
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.
Here’s a quick look at how Sentry handles your personal information (PII).
×We collect PII about people browsing our website, users of the Sentry service, prospective customers, and people who otherwise interact with us.
What if my PII is included in data sent to Sentry by a Sentry customer (e.g., someone using Sentry to monitor their app)? In this case you have to contact the Sentry customer (e.g., the maker of the app). We do not control the data that is sent to us through the Sentry service for the purposes of application monitoring.
Am I included?We may disclose your PII to the following type of recipients:
You may have the following rights related to your PII:
