    1. Quick version!


    
    First, we add the latest version of the org.spincast:spincast-default
    Maven artifact to our pom.xml (or build.gradle) :
    

        
            
<dependency>
    <groupId>org.spincast</groupId>
    <artifactId>spincast-default</artifactId>
    <version>{{spincast.spincastCurrrentVersion}}</version>
</dependency> 
        
    



    
    Then :

    

        
            
public class App {

    public static void main(String[] args) {
        Spincast.init(args);
    }

    @Inject
    protected void init(DefaultRouter router, Server server) {
        router.GET("/").handle(context -> context.response().sendHtml("<h1>Hello World!</h1>"));
        server.start();
    }
}   
        
        
            Explanation :

            (  Tip : try hovering/clicking the page numbers below! )
            

                
                    3 : A standard main(...)
                    method is the entry point of our application.
                
                
                    4 : Spincast.init(args) will 
                    create a Guice context using the default plugins, will
                    bind the current App class in the context and will load it.
                
                
                    7-8 : This init method
                    is going to be called automatically when the Guice context is ready. We inject in it the 
                    default Router and the
                    default Server.
                
                
                    9 : We define a Route for the index page
                    using an inline Route Handler based on a lambda.
                
                
                    10 : We start the server.
                
            
        
     



    
    Try it!
