What tutorial
Build web apps with just HTML.
File-based routing. Server state. Database. Auth. Forms. All from .html files — no JavaScript, no backend code. Ten short steps, each with live demos running on this very page.
Prefer to follow along locally?
This exact tutorial ships with the CLI — with hot reload, so you can edit each page as you read it:
cargo install run-what
run-what new my-app # choose the Tutorial template
cd my-app && run-what dev
Everything here is a live What app — the page you're reading is site/tutorial/index.html on this server. The interactive demos (counters, forms, notes) use your own session, so feel free to click everything.
