Simple & Elegant

No main() method required. Just pure logic.

package com.example;

import org.tinystruct.AbstractApplication;
import org.tinystruct.data.component.Builder;
import org.tinystruct.data.component.Builders;
import org.tinystruct.system.annotation.Action;

public class HelloApp extends AbstractApplication {
    @Action("hello")
    public String hello() {
        return "Hello, World!";
    }

    @Action("user")
    public Builder getUser(String id) {
        // Query from database
        // ...
        return new Builder();
    }
    
    @Override
    public void init() {
        this.setTemplateRequired(false);
    }
    
    @Override
    public String version() { return "1.0"; }
}
