Web Software Development

Welcome! In this free open online course, you’ll learn what web applications are, how they function, and how to build them. The course introduces designing, building, and testing server- and client-side functionality of web applications.


The technologies learned in the course include Deno, Hono, Deno KV, PostgreSQL, Svelte, Playwright, TailwindCSS, and Docker — we’ll naturally also learn HTML, CSS, and JavaScript on the side.
