Aspire.Qdrant.Client 8.0.0-preview.7.24251.11

Aspire.Qdrant.Client library

Registers a QdrantClient in the DI container for connecting to a Qdrant server.

Getting started

Prerequisites

• Qdrant server and connection string for accessing the server API endpoint.

Install the package

Install the .NET Aspire Qdrant Client library with NuGet:

dotnet add package Aspire.Qdrant.Client

Usage example

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

builder.AddQdrantClient("qdrant");

Configuration

The .NET Aspire Qdrant 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.AddQdrantClient():

builder.AddQdrantClient("qdrant");

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

{
  "ConnectionStrings": {
    "qdrant": "Endpoint=http://localhost:6334;Key=123456!@#$%"
  }
}

By default the QdrantClient uses the gRPC API endpoint.

Use configuration providers

The .NET Aspire Qdrant Client component supports Microsoft.Extensions.Configuration. It loads the QdrantSettings from configuration by using the Aspire:Qdrant:Client key. Example appsettings.json that configures some of the options:

{
  "Aspire": {
    "Qdrant": {
      "Client": {
        "Key": "123456!@#$%"
      }
    }
  }
}

Use inline delegates

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

builder.AddQdrantClient("qdrant", settings => settings.ApiKey = "12345!@#$%");

AppHost extensions

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

dotnet add package Aspire.Hosting.Qdrant

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

var qdrant = builder.AddQdrant("qdrant");

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

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

builder.AddQdrantClient("qdrant");
