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
