Capture Your First Error

Now that the Demo App is up and running on your local environment integrated with the Sentry SDK, you're ready to generate the first error.

Step 1: Capture your first event

  1. Launch the demo app by opening the localhost link in your browser

  2. Open the browser's Console to verify that an error has occurred

    Import and Configure SDK

  3. Click on any of the Buy! buttons to add products to your shopping cart

  4. Click on the Checkout button on the left panel to generate an error

    Import and Configure SDK

    Notice that:

    • An error message Something went wrong displays in the app

    • The error appears in the browser console

    • An alert sent to your email address configured on Sentry notifying you about an error that occurred in your app

      Import and Configure SDK

Step 2: Handle the error

  1. Go to your email inbox and open the email notification from Sentry

    Import and Configure SDK

  2. Click on View on Sentry to view the full details and context of this error in your Sentry account

    Import and Configure SDK Note: Sentry aggregates similar errors (events) into one Issue

  3. Scroll down to the Exception stack trace

    Error Stack-trace

    • Notice that the stack trace is minified. JavaScript is typically minified to reduce to the size of the source code.
    • Sentry can un-minify the code back to its readable form and display source (code) context lines in each stack frame, which is covered in the next section.
