Introduction

Welcome to Chapter 8! In our journey through Angular system design, we’ve explored how to structure applications, manage state, and build robust routing. But what good is a perfectly designed application if it’s slow and unresponsive? This chapter dives deep into Performance Budgeting and Optimization, a critical aspect of delivering high-quality user experiences.

Performance isn’t just a “nice-to-have”; it’s a fundamental requirement. Slow applications lead to frustrated users, higher bounce rates, lower conversion rates, and even poor search engine rankings. As architects, we need to proactively define performance targets, measure against them, and implement strategies to keep our applications fast and fluid.
