  As modern web applications grow in complexity, error monitoring and performance tracking in front-end development become critical. Catching bugs early and having real-time visibility into the client-side experience can make or break user satisfaction. Two major players dominate this space: Sentry and Datadog . Both provide robust monitoring capabilities, but they cater to slightly different needs. Let’s break it down. Why Front-End Error Monitoring Matters Immediate Feedback: Real-time error tracking reduces downtime and speeds up response. Improved UX: Proactively fixing bugs improves customer experience. Debugging at Scale: Helps isolate issues by browser, device, user sessions, or environments. Sentry vs. Datadog – A Comparative Breakdown Minimize image Edit image Delete image When to Use What? Use Sentry if : You want clean stack traces, detailed error context, and lightweight integration into your front-end app (React, Vue, Next.js, etc.). Use Datadog if : You're monit...

In today’s fast-paced digital landscape, performance isn’t just a luxury — it’s a necessity. A delay of even 100 milliseconds can impact user experience and conversion rates. That's why monitoring front-end performance is crucial for any modern web application. Two powerful tools in the performance monitoring arsenal are Web Vitals and Google Lighthouse . Let's explore what they are, how they work, and how you can leverage them to ensure your applications stay lightning-fast and user-friendly. What Are Web Vitals? Web Vitals is an initiative by Google to provide unified guidance on essential metrics that matter most to user experience. The Core Web Vitals: Largest Contentful Paint (LCP): Measures loading performance. Target: < 2.5s First Input Delay (FID): Measures interactivity. Target: < 100ms Cumulative Layout Shift (CLS): Measures visual stability. Target: < 0.1 These metrics focus on actual user perception and interaction, helping developers prioritize real-...
