Svelte & SvelteKit, v2

Rich Harris develops a file-storage application with Svelte and SvelteKit, connecting reactive components with server workflows, authentication and file handling. Published in August 2026, the course includes attention to accessibility, errors and efficient data loading. It suits web developers who want to understand the decisions behind a complete application rather than only reproduce its interface.

What you will learn

• Use runes and reactive components.
• Connect server workflows with forms and authentication.
• Build file-upload and browsing interfaces.

Who this suits

A solid grasp of HTML, CSS and modern JavaScript is required, along with comfort using Node.js and the command line.

Before you enroll

Match the course’s Svelte and SvelteKit versions to your project. Older reactivity, slots, routing and Sapper examples may require migration for Svelte 5 applications. Hosting, databases, payment services and AI APIs can cost extra. Test error handling, accessibility and authorization independently before adapting a demonstration for real users.
