Most applications have select user journeys that matter. When those flows break or slow down, you feel it immediately in conversion, trust, and support load.

In this hands-on workshop, we'll walk through how to use Sentry for Critical Experience Monitoring in a Next.js ecommerce app. The focus is not "monitor everything", but monitor what actually matters to users and the business.

We'll cover:

• Setting up Sentry in a Next.js application

• Instrumenting critical user journeys: product browsing, add to cart, checkout

• Tracking errors and performance at each step of the funnel

• Building a Critical Experience Dashboard to spot regressions fast and prioritize fixes

By the end, you'll have a clear, repeatable approach to monitoring user experiences the way users experience them, end to end, in production, under real traffic.
