The Deno SDK is currently in Beta.

We have recently released v8 of the JavaScript SDKs. If you're using version 7.x, we recommend upgrading to the latest version. Check out the Migration docs to learn how to update your code to be compatible with v8.

Don't already have an account and Sentry project established? Head over to, then return to this page.

Configuration should happen as early as possible in your application's lifecycle.

import * as Sentry from "";

  dsn: "",

  // Set tracesSampleRate to 1.0 to capture 100%
  // of transactions for performance monitoring.
  // We recommend adjusting this value in production
  tracesSampleRate: 1.0,

To ensure the SDK can send events, you should enable network access for your ingestion domain:

deno run index.ts

To ensure the SDK can include your source code in stack traces, you should enable read access for your source files:

deno run --allow-read=./src index.ts 

This snippet includes an intentional error, so you can test that everything is working as soon as you set it up.

Verify your setup by adding the following snippet anywhere in your code and running it:

setTimeout(() => {
  throw new Error();

Learn more about manually capturing an error or message in our Usage documentation.

To view and resolve the recorded error, log into 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.
