Multipage applications (MPAs) and single-page applications (SPAs) are two prevalent design patterns for web apps, each with distinct lifecycles and user experiences. MPAs require full-page reloads for new data requests, while SPAs load static files initially, updating only the necessary data without reloading the entire page, offering faster performance and enhanced user experience. However, SPAs face challenges like difficulty in retrieving views on subsequent loads due to state not being tied to URLs. This article details the creation of a SPA using Svelte, integrating the svelte-spa-router for routing. It involves setting up a blog application with features such as direct routes, parameterized routes, and wildcards, emphasizing the simplicity and browser compatibility of the svelte-spa-router's hash-based paths. The guide also covers setting up the development environment, creating components and routes, and testing the application's functionality, while highlighting Svelte's potential for expansion with additional components, CMS integration, or database systems.
