Stardust.Paradox

Entity framework'ish tool for developing .net applications using gremlin graph query language with CosmosDb

Usage (asp.net core)

Startup.cs

ConfigureServices

Add the generated entity implementations to the IOC container (I will provide an extention method to make this easier)

 services.AddEntityBinding((entityType, entityImplementation) => services.AddTransient(entityType, entityImplementation))
        .AddScoped<MyEntityContext,MyEntityContext>()
        .AddScoped<IGremlinLanguageConnector>(s => new CosmosDbLanguageConnector(DbAccountName, AccessKey, "databaseName","collectionName"));

Defining the model

[VertexLabel("person")]
public interface IPerson : IVertex
{
    string Id {get;}

    string FirstName { get; set; }

    string LastName { get; set; }
    
    string Email { get; set; }

    IEdgeCollection<IPerson> Parents { get; }

    IEdgeCollection<IPerson> Children { get; }

    IEdgeCollection<IPerson> Siblings { get; }

    [EdgeLabel("city")] //pointing to the Residents property in ICity
    IEdgeReference<ICity> HomeCity { get; }//use IEdgeReference to enable task-async operations

    IEdgeCollection<ICompany> Employers { get; }
}

[VertexLabel("city")]
public interface ICity : IVertex
{
    string Id { get; }

    string Name { get; set; }

    string ZipCode { get; set; }
    

   [ReverseEdgeLabel("city")] //pointing to the HomCity property in IPerson
    IEdgeCollection<Iperson> Residents { get; } //use IEdgeCollection to enable task-async operations on the collection

    IEdgeReference<ICountry> Country { get; }
}

[VertexLabel("company")]
public interface ICompany : IVertex
{
    string Id { get; }

    string Name { get; set; }

    IEdgeCollection<ICompany> Employees { get; }
}

[VertexLabel("country")]
public interface ICountry : IVertex
{
    string Id { get; }

    string Name { get; set; }

    string CountryCode { get; set; }

    string PhoneNoPrefix { get; set; }

    IEdgeCollection<ICity> Cities { get; }
}

Defining the entity context and generating the entity implementations

public class MyEntityContext : Stardust.Paradox.Data.GraphContextBase
{
    public IGraphSet<IPerson> Persons => GraphSet<IPerson>();

    public IGraphSet<ICity> Cities => GraphSet<ICity>();

    public IGraphSet<ICountry> Countries => GraphSet<ICountry>();

    public IGraphSet<ICompany> Companies => GraphSet<ICompany>();

    public MyEntityContext(IGremlinLanguageConnector connector, IServiceProvider resolver) : base(connector, resolver)
    {
    }

    protected override bool InitializeModel(IGraphConfiguration configuration)
    {
        //Added some fluent configuration of the edges
        configuration.ConfigureCollection<IPerson>()
                .AddEdge(t => t.Children, "children").Reverse<IPerson>(t => t.Parents)
            .ConfigureCollection<ICity>()
            .ConfigureCollection<ICountry>()
                .AddEdge(t=>t.Cities).Reverse<ICountry>(t=>t.Country)
            .ConfigureCollection<ICompany>()
                .AddEdge(t => t.Employees, "employees").Reverse<IPerson>(t => t.Employers);
        return true;
    }
}
