Official Sentry SDK for Deno (Beta)

Links

• Official SDK Docs

The Sentry Deno SDK is in beta. Please help us improve the SDK by reporting any issues or giving us feedback.

Usage

To use this SDK, call Sentry.init(options) as early as possible in the main entry module. This will initialize the SDK and hook into the environment. Note that you can turn off almost all side effects using the respective options.

import * as Sentry from 'npm:@sentry/deno';

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

To set context information or send manual events, use the exported functions of the Deno SDK. Note that these functions will not perform any action before you have called init():

// Set user information, as well as tags and further extras
Sentry.setExtra('battery', 0.7);
Sentry.setTag('user_mode', 'admin');
Sentry.setUser({ id: '4711' });

// Add a breadcrumb for future events
Sentry.addBreadcrumb({
  message: 'My Breadcrumb',
  // ...
});

// Capture exceptions, messages or manual events
Sentry.captureMessage('Hello, world!');
Sentry.captureException(new Error('Good bye'));
Sentry.captureEvent({
  message: 'Manual',
  stacktrace: [
    // ...
  ],
});

Auto-instrumentation (experimental)

Some libraries (e.g. mysql) don't emit tracing signals on their own. To instrument them, Sentry uses orchestrion to transform them at load time so they publish to node:diagnostics_channel.

In Deno versions prior to 2.8.0, this is not available, as it relies on Module.registerHooks, which was added in that version.

As of Deno 2.8.3, you can use the --import or --preload argument to deno run in order to enable these instrumentations.

$ deno run --import=@sentry/deno/import app.ts

[!NOTE] In Deno versions 2.8.0 through 2.8.2, a bug causes Deno to deadlock when a module hook is added in this way. As a workaround, you can import the loader explicitly, and then dynamically import your app to take advantage of the added module loading hooks.

import 'npm:@sentry/deno/import';
await import('./app.ts');

In both cases, your app.ts should simply load Sentry as usual:

// app.ts

// initialize Sentry as early as possible
import * as Sentry from 'npm:@sentry/deno';
Sentry.init({ dsn: '__DSN__' });

// ... the rest of the app...
