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.

Integrating vanilla JavaScript UI libraries into Svelte

First, we will explore UI libraries that are written in vanilla JavaScript. When we use the phrase vanilla JavaScript, we’re referring to plain JavaScript, or JavaScript in the absence of frameworks or libraries.

There are many reasons a UI library is written in vanilla JavaScript:

  • Performance reasons – it would be much easier to optimize without the abstractions from the web framework
  • The library author’s personal preference to be framework-agnostic
  • The library was created predating any modern web frameworks

For us, vanilla JavaScript UI libraries are great because they do not depend on any specific framework runtime, which is an extra overhead on top of the UI library itself.

For example, if we use a calendar component library that is implemented in React, then besides installing the calendar component library, we would need to install React’s framework as well.
