What you'll learn

Modern frameworks often suffer from sluggish startup performance due to their reliance on client-side hydration, resulting in wasted resources and delayed interactivity. In this course, Qwik City Foundations, you’ll learn to build high-performance web apps using Qwik City’s resumable architecture. First, you’ll explore how Qwik’s unique execution model eliminates hydration and enables fine-grained lazy loading. Next, you’ll discover how to structure your app with components, pages, layouts, and progressive enhancement techniques. Finally, you’ll learn how to handle user input and data using Qwik City’s form actions, signals, and server-side data fetching. When you’re finished with this course, you’ll have the skills and knowledge of Qwik City needed to create fast, scalable, and interactive applications that minimize JavaScript and maximize performance.
