CommunityToolkit.Aspire.RavenDB.Client

CommunityToolkit.Aspire.RavenDB.Client library

Registers IDocumentStore and the associated IDocumentSession and IAsyncDocumentSession instances in the DI container for connecting to a RavenDB database. Additionally, it enables health checks, metrics, logging, and telemetry.

Getting started

Prerequisites

• RavenDB database and connection string for accessing the database or a running RavenDB server instance with its connection details, such as the server's URL and a valid certificate if required.

Note:
RavenDB allows creating an IDocumentStore without a defined database. In such cases, IDocumentSession and IAsyncDocumentSession will not be available. This library also supports creating a new RavenDB database. However, if you intend to connect to an existing RavenDB database, ensure the database exists and you have its connection details.

Install the package

Install the CommunityToolkit.Aspire.RavenDB.Client library with NuGet:

dotnet add package CommunityToolkit.Aspire.RavenDB.Client

To be added once the package is published.

Usage example

In the Program.cs file of your project, call the AddRavenDBClient extension method to register a IDocumentStore for use via the dependency injection container. The method takes a connection name parameter.

builder.AddRavenDBClient("ravendb");

You can then retrieve a IDocumentStore instance using dependency injection, for example:

public class MyService
{
    private readonly IDocumentStore _documentStore;
    public MyService(IDocumentStore documentStore)
    {
        _documentStore = documentStore;
    }

    // Your logic here
}

Configuration

The .NET Aspire RavenDB Client component provides multiple options to configure the server connection based on the requirements and conventions of your project.

Use a connection string

When using a connection string from the ConnectionStrings configuration section, you can provide the name of the connection string when calling builder.AddRavenDBClient():

builder.AddRavenDBClient("ravendb");

And then the connection string will be retrieved from the ConnectionStrings configuration section:

{
  "ConnectionStrings": {
    "ravendb": "URL=http://localhost:8080;Database=ravenDatabase"
  }
}

Use configuration providers

The .NET Aspire RavenDB Client component supports Microsoft.Extensions.Configuration. It loads the RavenDBClientSettings from configuration by using the Aspire:RavenDB:Client key.

Use inline delegates

Also you can pass the Action<RavenDBClientSettings> configureSettings delegate to set up some or all the options inline, for example to set the database name and certificate from code:

builder.AddRavenDBClient("ravendb", settings => 
{
    settings.DatabaseName = "ravenDatabase"; 
    settings.Certificate = ravenCertificate;
});

Use RavenDBClientSettings Class

The RavenDBClientSettings class simplifies configuration by allowing you to specify:

• URLs of your RavenDB nodes.
• Database name to connect to or create.
• Certificate details (via CertificatePath and CertificatePassword or Certificate).
• Optional actions to modify the IDocumentStore.

Example for creating a new database on a local unsecured RavenDB server:

var settings = new RavenDBClientSettings(new[] { �http://127.0.0.1:8080� }, �NorthWind�)
{
	CreateDatabase = true;
};
builder.AddRavenDBClient(settings);

You can also configure:

• DisableHealthChecks to disable health checks.
• HealthCheckTimeout to set the timeout for health checks.
• DisableTracing to disable OpenTelemetry tracing.

AppHost extensions

Install the CommunityToolkit.Aspire.Hosting.RavenDB Library

Install the CommunityToolkit.Aspire.Hosting.RavenDB library with NuGet:

dotnet add package CommunityToolkit.Aspire.Hosting.RavenDB

To be added once the package is published.

Usage in AppHost

In your AppHost's Program.cs file, register a RavenDB server resource and consume the connection using the following methods:

var ravendb = builder.AddRavenDB("ravendb");

var myService = builder.AddProject<Projects.MyService>()
                       .WithReference(ravendb);

The WithReference method configures a connection in the MyService project named ravendb. In the Program.cs file of MyService, the RavenDB connection can be consumed using:

builder.AddRavenDBClient("ravendb");
