Svelte 3 Up and Running

By: Alessandro Segala

Overview of this book

Svelte is a modern JavaScript framework used to build static web apps that are fast and lean, as well as being fun for developers to use. This book is a concise and practical introduction for those who are new to the Svelte framework which will have you up to speed with building apps quickly, and teach you how to use Svelte 3 to build apps that offer a great app user experience (UX). The book starts with an introduction to Svelte 3, before showing you how to set up your first complete application with the framework. Filled with code samples, each chapter will show you how to write components using the Svelte template syntax and the application programming interfaces (APIs) of the Svelte framework. As you advance, you’ll go from scaffolding your project and tool setup all the way through to production with DevOps principles such as automated testing, continuous integration, and continuous delivery (CI/CD). Finally, you’ll deploy your application in the cloud with object storage services and a content delivery network (CDN) for best-in-class performance for your users. By the end of this book, you’ll have learned how to build and deploy apps using Svelte 3 to solve real-world problems and deliver impressive results.

Sapper

Sapper (https://sapper.svelte.dev/) is a full-featured application framework for building multi-page Progressive Web Apps (PWAs). Sapper is based on Svelte 3, which it uses to allow developers to build pages and components, and it is maintained as a sub-project of Svelte itself. Among developers working with Svelte, Sapper has a modest but growing fanbase. (We saw a brief mention of multi-page applications and PWAs in Chapter 1, Meet Svelte, and we compared them with Single-Page Applications (SPAs), such as the one we were about to start building, throughout this book.)

With Sapper, developers can write components using Svelte, just like we've seen in Chapter 3, Building Reactive Svelte Components, and Chapter 4, Putting your App Together. Sapper then automatically builds multi-page PWAs, enabling features such as Server-Side Rendering (SSR), routing (using a SEO-friendly router based on the HTML5 History API, which means it's better indexed by search engines),...
