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
Launch the demo app by opening the localhost link in your browser
Open the browser Developers Console to verify that an error is generated
Click on any of the Buy! buttons to add products to your shopping cart

- Sentry can un-minify the code back to its readable form and display source (code) context lines in the stack frames. We will configure that in the next tutorial.
Step 3: Create New Alerts
You can create various alert rules per project and let Sentry know when, how, and who you want notified when errors occur in your application. Alert rules consist of Conditions and Actions which are performed once the associated conditions are met. For more information, see Alerts.

In this step, you will create a new Alert rule notifying every time an event occurs even if it’s associated with an already existing issue.
Click on the cog icon next to the project name to open the
