Overview of this book

Svelte has quickly become a popular choice among developers seeking to build fast, responsive, and efficient web applications that are high-performing, scalable, and visually stunning. This book goes beyond the basics to help you thoroughly explore the core concepts that make Svelte stand out among other frameworks. You’ll begin by gaining a clear understanding of lifecycle functions, reusable hooks, and various styling options such as Tailwind CSS and CSS variables. Next, you’ll find out how to effectively manage the state, props, and bindings and explore component patterns for better organization. You’ll also discover how to create patterns using actions, demonstrate custom events, integrate vanilla JS UI libraries, and progressively enhance UI elements. As you advance, you’ll delve into state management with context and stores, implement custom stores, handle complex data, and manage states effectively, along with creating renderless components for specialized functionalities and learning animations with tweened and spring stores. The concluding chapters will help you focus on enhancing UI elements with transitions while covering accessibility considerations. By the end of this book, you’ll be equipped to unlock Svelte's full potential, build exceptional web applications, and deliver performant, responsive, and inclusive user experiences.

Having alternative transitions for inaccessible users

Users with vestibular disorders may feel discomfort when exposed to motion-based animations, such as scaling or panning large objects. However, they are generally less affected by subtler animations, such as fading.

Switching all transitions to fading for users with vestibular disorders is not a one-size-fits-all solution. It is always better to seek feedback from the users themselves.

We will continue using the same example from the previous section and explore how we can switch from the fly transition to a fade transition when a user prefers reduced motion.

One thing to note is that, in Svelte, you are not allowed to apply more than one transition to an element.

For example, the following code is invalid and will result in a build error:

<div transition:fade transition:fly />

This means we can’t apply two transitions to an element and then decide which one to use. We must find a way to switch between...
