Prerequisites

• You need a Sentry account and project

Configure

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

In addition to capturing errors, you can monitor interactions between multiple services or applications by enabling tracing.

Select which Sentry features you'd like to install in addition to Error Monitoring to get the corresponding installation and configuration instructions below.

import * as Sentry from "https://deno.land/x/sentry/index.mjs";

Sentry.init({
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",

  // Set tracesSampleRate to 1.0 to capture 100%
  // of transactions for performance monitoring.
  // We recommend adjusting this value in production
  // Learn more at
  // https://docs.sentry.io/platforms/javascript/configuration/options/#traces-sample-rate
  tracesSampleRate: 1.0,
});

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

deno run --allow-net=o0.ingest.sentry.io index.ts

Allow access to your source files

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 

Verify

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();
});

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