The Starcounter app project structure is inspired by the structure of ASP.NET 5 projects. The difference is that ASP.NET has Controllers, Models, Scripts, and Views while Starcounter has Api handlers, JSON + HTML viewmodels and database classes.

This tree displays the structure of a Starcounter project:

Namespaces

Api, Database, Helpers, and ViewModels folders may or may not have their own namespace.

A json view model class would look like this:

using Starcounter;
​
namespace StarcounterSample 
{
    public class MainPage : Json 
    {
    }
}

A helper file inside Helpers folder would look like this:

namespace StarcounterSample 
{
    public class StringsHelper 
    {
    }
}

A handler file inside Api folder would look like this:

using Starcounter;
​
namespace StarcounterSample 
{
    public class MainHandlers 
    {
        public void Register() 
        {
            Handle.GET("/StarcounterSample", () => new MainPage());
        }
    }
}

Custom sub-folders and sub-namespaces could be used if needed.

A view page inside sub-folder: StarcounterSample/ViewModels/Launcher/AppMenuPage.json.

using Starcounter;
​
namespace StarcounterSample.Launcher 
{
    public class AppMenuPage: Json 
    {
    }
}

C# files & Classes

Name of .cs and .json files should be exactly the same as classes inside. Name of .json and .json.cs files should also match.

The correct structure for sign in page would be like this:

• ViewModels/SignInPage.json

• ViewModels/SignInPage.json.cs

• class SignInPage : Json

Html Page Files

Html files which represent a json view model like SignInPage.Html should be named exactly the same as name of json file.

This is correct:

{
    "Html": "/GoogleSignIn/views/SignInPage.html"
}

And these are incorrect:

{
    "Html": "/GoogleSignIn/views/signinpage.html"
}

{
    "Html": "/GoogleSignIn/views/sign-in-page.html"
}

Custom Elements

The html files which do not represent any of json page should be stored inside elements folder. The name of a file should be exactly the same as name of the element inside.

JavaScript Libraries

Most of the Starcounter applications do not use custom JavaScript libraries outside of WebComponents. If you need a custom JavaScript library then it should be scoped to your application and saved inside a js folder.

Startup Program.cs Class

• In small applicaions, the startup class may register handlers and make some preparations.

• In big applications, the startup class should be minified and only call Register method of /Api/ classes.

Visual Studio Files

Visual Studio solution (sln) and project (csproj, kproj) files should be checked in to the version control system.

User preference files (suo), which carry information about unloaded projects in a solution or breakpoints in a project, should not be checked in to the version control system.
