CommunityToolkit.Aspire.GoFeatureFlag 9.8.0-beta.401

CommunityToolkit.Aspire.GoFeatureFlag

Registers a GoFeatureFlagProvider in the DI container for connecting to a GO Feature Flag instance.

Getting started

Install the package

Install the .NET Aspire GO Feature Flag Client library with NuGet:

dotnet add package CommunityToolkit.Aspire.GoFeatureFlag

Usage example

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

builder.AddGoFeatureFlagClient("goff");

Configuration

The .NET Aspire GO Feature Flag 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.AddGoFeatureFlagClient():

builder.AddGoFeatureFlagClient("goff");

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

{
    "ConnectionStrings": {
        "goff": "Endpoint=http://localhost:19530/"
    }
}

Use configuration providers

The .NET Aspire GO Feature Flag Client integration supports Microsoft.Extensions.Configuration. It loads the GoFeatureFlagClientSettings from configuration by using the Aspire:GoFeatureFlag:Client key. Example appsettings.json that configures some of the options:

{
    "Aspire": {
        "GoFeatureFlag": {
            "Client": {
                "Endpoint": "http://localhost:19530/",
                "MasterKey": "123456!@#$%"
            }
        }
    }
}

Use inline delegates

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

builder.AddGoFeatureFlagClient("goff", settings => settings.ProviderOptions.ApiKey = "123456!@#$%");

AppHost extensions

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

dotnet add package CommunityToolkit.Aspire.Hosting.GoFeatureFlag

Then, in the Program.cs file of AppHost, register a GO Feature Flag instance and consume the connection using the following methods:

var goff = builder.AddGoFeatureFlag("goff");

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

The WithReference method configures a connection in the MyService project named goff. In the Program.cs file of MyService, the GO Feature Flag connection can be consumed using:

builder.AddGoFeatureFlagClient("goff");

Then, in your service, inject GoFeatureFlagProvider and use it to interact with the GO Feature Flag API:

public class MyService(GoFeatureFlagProvider goFeatureFlagProvider)
{
    // ...
}
