Ever used an app that crashed and thought, "Why can’t this just work?" For users, it’s frustrating. For businesses, it’s expensive. As JavaScript developers, we’re stuck in the middle - juggling frontend tweaks, backend performance, and monitoring tools to figure out what went wrong. That’s where observability comes in because understanding your code is like going to the gym. No shortcuts, no pills. You gotta put in the work to put on the muscle.  It’s not just some SRE buzzword anymore but a must-have for developers. Observability helps you spot issues, understand system behavior, and fix problems faster. And with OpenTelemetry, you get an open-source framework to manage logs, traces, and metrics without vendor lock-in. In this session, you’ll learn, all things observability, optimize both frontend and backend, and integrate OpenTelemetry to gain insights into your system. Moreover, you'll also learn how to practically integrate OpenTelemetry into your JavaScript apps, to create spans, track activities, name them effectively. The result? Fewer headaches, better performance, and apps that not just works but you completely understands.

Have you ever had that sinking feeling when your favorite app suddenly stops working? You’re not alone. Frontend teams focus on client-side performance to enhance user experience, where customers spend time and revenue is generated. Tools like RUM and Synthetic Monitoring help, but they're outdated and not sufficient. Say hi to Frontend Observability, a holistic and end-to-end approach to investigate errors and latencies.

Have you ever considered that when we encounter terms like observability and reliability, our initial instinct is usually to attribute them solely to SRE concerns? Yet, upon closer examination, one may realize that actually implementing observability is, in essence, more aligned with the domain of developers. After all, developers are the ones who directly implement the actual logic into our existing codebase, and who better to understand and debug their code than the developers themselves? Through this session, we will emphasize on understanding the importance of observability specifically from a developer's perspective. Let's explore some best practices that help us effectively debug the performance of our Node application and how the inclusion of open source frameworks like OpenTelemetry could be beneficial to us.
