Sapper and Svelte: A quick tutorial

The tutorial provides an overview of Sapper, a framework designed to work with Svelte for building larger and more complex web applications with features like routing, server-side rendering, and automatic code splitting. It discusses the transition from Sapper to its successor, SvelteKit, which aims to simplify onboarding, reduce maintenance, and support a modern unbundled development workflow. Although Sapper will no longer be maintained, the text explains its project structure, routing system, and server-side rendering capabilities, illustrating how it integrates with Svelte to create efficient web applications. Additionally, the tutorial provides insights into the handling of page and server routes, dynamic imports for third-party modules, and the overall ease of building apps with Sapper, encouraging developers to consider migrating to SvelteKit while still offering guidance for those who choose to continue using Sapper.
