Caution
Never ever use this code in production!
This is an intentionally broken(!!) Datastar 🚀 backend that has absolutely no dependency beside the default Java JDK 21+.
😎 But at least the Hello World example is functional 😎.
You probably never build a Java project without a build tool, but this is very easy:
javac -cp dev/datastar:. nodependency.javathen run the compiled code
java nodependency
