Introduction

Welcome to Chapter 12! So far, we’ve explored how to architect robust and scalable React applications, from choosing rendering strategies to managing microfrontends and ensuring offline resilience. But what happens after your beautifully designed application is deployed? How do you know if it’s actually performing well for your users? Are there hidden errors impacting their experience? This is where observability, monitoring, and alerting come into play.

In this chapter, we’ll dive deep into the crucial practices of understanding your frontend application’s health and user experience in real-time. We’ll learn how to proactively identify issues, track performance bottlenecks, and set up intelligent alerts that notify you before a small glitch becomes a major outage. Mastering these concepts is essential for any modern frontend engineer looking to build truly reliable and performant systems.
