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.

Composing Components

As your application grows, cramming all the logic into a single component becomes impractical. You’ll need to split your app into smaller, modular components and assemble them to form a more complex application.

In this chapter, we’ll explore various techniques to combine components effectively. We’ll start by examining how to inject custom content into a component using slots. Then, we’ll discuss how to conditionally render different HTML elements within a component. We’ll also delve into recursive components, useful for displaying nested or hierarchical data.

We’ll guide you through each topic with hands-on examples, ensuring the techniques you learn are both practical and applicable in real-world scenarios. By the end of this chapter, you’ll have a richer set of strategies to compose components in your Svelte applications.

In this chapter, you will learn the following:
