Harness the power of Svelte, the cutting-edge JavaScript framework used for building high-performance web applications, with this definitive guide Key Features Create Svelte component lifecycles by styling and theming components as well as managing props and states Leverage actions to build custom events, integrate libraries, and enhance UI elements progressively Explore transitions, write custom transitions, and go through accessibility with transitions in Svelte Purchase of the print or Kindle book includes a free PDF eBook Book Description 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. What you will learn Master Svelte component development and write efficient Svelte code Implement styling and theming techniques to create visually stunning UIs Create reusable and composable Svelte components for better code organization Understand state management with context and stores for scalable applications Explore different use cases of Svelte stores and Svelte context Utilize tweened and spring stores for complex animations and custom easing Who this book is for This book is for experienced web developers looking to enhance their skills and create high-performance web applications. Familiarity with JavaScript, frontend development, and basic Svelte concepts is recommended, making it ideal for professionals and developers who want to master Svelte's advanced features. |
