A example of using Java, Javalin and HTMX for building webapps.

HTMX Java example

WTF is this?

This is a groundbreaking piece of technology. This application combines blockchain, AI and secrets stolen from Area 51 to bring you wealth beyond your wildest dreams.

Really?

Nah, it's just a todo list app.

Great, we need more of them.

I agree! This one has a bit of a unique stack, it uses:

• Java (Yes, people still use this!)
• HTMX: Frontend """framework"""
• picocss: Minimal CSS library (the first result for "minimal css")
• Javalin: Backend web server.
• j2html: Html builder library.

Which allows the whole thing to be written a single Java file. There is not a single line of Javascript in this whole project!^

^ Yes, technically HTMX does bring in Javascript but ya know what I'm saying.

Wow...there is an awful lot of inline styling in this project.

This is just an example application, not a fully fledged deploy-on-prod thing!

If you were doing it properly, maybe you would write it in css files, import tailwind or something.

Alright alright, how do I run this?

Load it in your favourite Java IDE (like IntelliJ or....uh...) and run the main method in Server. Access it via localhost:8080 in a web browser.

In the root directory, we can also run it by:

1. mvn package
2. java -jar target/htmx-1.0-SNAPSHOT.jar
