CommunityToolkit.Aspire.SurrealDb 9.7.2

CommunityToolkit.Aspire.SurrealDb

Registers a SurrealDbClient in the DI container for connecting to a SurrealDB instance.

Getting started

Prerequisites

• SurrealDB cluster.

Install the package

Install the .NET Aspire SurrealDB Client library with NuGet:

dotnet add package CommunityToolkit.Aspire.SurrealDb

Usage example

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

builder.AddSurrealClient("surreal");

Configuration

The .NET Aspire SurrealDB Client integration 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.AddSurrealClient():

builder.AddSurrealClient("surreal");

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

{
    "ConnectionStrings": {
        "surreal": "Server=ws://127.0.0.1:8000/rpc;Namespace=test;Database=test;Username=root;Password=root"
    }
}

Use configuration providers

The .NET Aspire SurrealDB Client integration supports Microsoft.Extensions.Configuration. It loads the SurrealDbClientSettings from configuration by using the Aspire:Surreal:Client key. Example appsettings.json that configures some of the options:

{
  "Aspire": {
    "Surreal": {
      "Client": {
        "Options": {
          "Endpoint": "ws://127.0.0.1:8000/rpc", 
          "Namespace": "test",
          "Database": "test",
          "Username": "root",
          "Password": "root"
        }
      }
    }
  }
}

Use inline delegates

Also you can pass the Action<SurrealDbClientSettings> configureSettings delegate to set up some or all the options inline, for example to set the API key from code:

builder.AddSurrealDbClient("surreal", settings => settings.Options.Endpoint = "ws://localhost:8000/rpc");

AppHost extensions

In your AppHost project, install the CommunityToolkit.Aspire.Hosting.SurrealDb library with NuGet:

dotnet add package CommunityToolkit.Aspire.Hosting.SurrealDb

Then, in the Program.cs file of AppHost, register a SurrealDB cluster and consume the connection using the following methods:

var db = builder.AddSurrealServer("surreal")
                .AddNamespace("ns")
                .AddDatabase("db");

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

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

builder.AddSurrealClient("db");

Then, in your service, inject SurrealDbClient and use it to interact with the SurrealDB instance:

public class MyService(SurrealDbClient client)
{
    // ...
}
