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.

The Container/Presentational pattern

As your application scales in complexity, you may find it beneficial to adopt specific design patterns or guidelines to structure components. One such approach is the Container/Presentational pattern, which divides a component into two categories, the Container component and the Presentational component:

  • Container components focus on functionality. They handle data fetching, state management, and user interactions. While they usually don’t render Document Object Model (DOM) elements themselves, they wrap around Presentational components and supply them with data and actions.
  • Presentational components are all about the user interface. They get their data and event-handling functions exclusively through props, making them highly reusable and straightforward to test.

A common scenario where you’ll see this pattern in action is when using a UI component library. In this case, the library’s components serve as...
