Bun Add Sentry to a Bun app

Add Sentry to a Bun app

Sentry is a developer-first error tracking and performance monitoring platform. Sentry has a first-class SDK for Bun, @sentry/bun, that instruments your Bun application to automatically collect error and performance data.

To start using Sentry with Bun, first install the Sentry Bun SDK.

bun add @sentry/bun

Then, initialize the Sentry SDK with your Sentry DSN in your app's entry file. You can find your DSN in your Sentry project settings.

import * as Sentry from "@sentry/bun";

// Ensure to call this before importing any other modules!
Sentry.init({
  dsn: "__SENTRY_DSN__",

  // Add Performance Monitoring by setting tracesSampleRate
  // We recommend adjusting this value in production
  tracesSampleRate: 1.0,
});

You can verify that Sentry is working by capturing a test error:

setTimeout(() => {
  try {
    foo();
  } catch (e) {
    Sentry.captureException(e);
  }
}, 99);

To view and resolve the recorded error, log into sentry.io and open your project. Clicking on the error's title will open a page where you can see detailed information and mark it as resolved.
