htmx-ktor

A compact Kotlin/Ktor sample that renders HTML on the server and uses htmx for component-style page updates without a separate JavaScript framework.

htmx-ktor is a small server-rendered web app that explores how far a Kotlin backend can go when the browser interaction model stays simple.

The app renders HTML with Ktor and uses htmx to replace focused parts of the page in response to user actions. That keeps the interaction style close to component updates without adding a separate JavaScript framework or duplicating view state on the client.

Stack

  • Kotlin and Ktor for the application server
  • htmx for declarative page updates
  • Tailwind CSS for styling
  • Docker for packaging
  • DigitalOcean App Platform for hosting

What it demonstrates

The project is intentionally compact. It is meant to show the full path from a server-rendered Kotlin app to a hosted demo, including containerization and deployment, without pulling in a client-side application framework.

The live demo links back to the GitHub repository, and the repository README links to the demo, so both entry points stay connected.
