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.

Summary

In this chapter, we learned how to use actions to integrate UI libraries, either written in vanilla JavaScript or any other frameworks into Svelte. We went through two real-world examples – integrating Tippy.js and react-calendar into Svelte using Svelte actions. In both examples, we went through a step-by-step process of writing out a Svelte action. We started by creating the structure of a Svelte action and then filled up the steps within the action for when the Svelte action is initialized as the element is created, when the data changes, and when the element is removed from the DOM. We also discussed why we choose to use Svelte actions, as well as the other alternatives and considerations when it comes to integrating UI libraries.

In the next chapter, we will look at the next common pattern of actions, which is to progressively enhance your elements.
