Get Started

Here's a minimal "Hello World" Spry application to get you started:

Vala 
public class HelloPage : PageComponent {
    public override string markup { get {
        return """<!DOCTYPE html>
<html>
<body>
    <h1>Hello, Spry!</h1>
</body>
</html>""";
    }}
}

// In Main.vala
spry_cfg.add_page<HelloPage>(new EndpointRoute("/"));
