sample-htmx-javalin

Sample application showing how htmx teams up with javalin so i can compare with this one

Dependencies

• java 17 or newer
• kotlin 1.9
• jdbi 3.44
• htmx 2.x
• apache velocity 2.3
• spock 2.3

A good kotlin ide is also recommended.

How to build

We have shadow jar plugin to ease runnable jar creation

./gradlew shadowJar

How to run

We have application plugin to ease runnable jar creation options

./gradlew run

Alternatively, run the jar built in previous step:

java -jar build/libs/sample-htmx-javalin-1.0-SNAPSHOT-all.jar

Noteworthy

• Shadow plugin does similar job done by maven shade plugin
• Javalin supports a good range of template engines, just pick one
• There are a good amount of logging options to Javalin
• Testing Javalin is simple and ergonomic thanks to its testing library
• Spock demands us to enable the groovy language in the project
• Groovy support has issues to proper set jvm toolchain, fallbacks to system
• There is a nice htmx plugin for intellij
• JDBI fluent api makes database access easier
• TodoItem needs an empty constructor so JDBI bean mapper can fill attributes in
• Intellij coverage plugin has an issue with velocity
• JaCoCo plugin just works even the test source set being multilingual

Next steps

• Add a filter in the template. Backend already supports the 'q' parameter
• Find a good form to object mapper would be handy. Javalin has validators but besides that, form to model mapping is pretty much manual
• Setup docker image building and registry publishing
