CloudBees Feature Management provider for OpenFeature

This is the CloudBees provider implementation for OpenFeature for the dotnet SDK.

OpenFeature provides a vendor-agnostic abstraction layer on Feature Flag management.

This provider allows the use of CloudBees Feature Management as a backend for Feature Flag configurations.

Requirements

• netframework 4.5.1 or greater
• .net core 3.1 or greater

Configuration

Follow the instructions on the dotnet SDK project for how to use the dotnet SDK.

You can configure the CloudBees provider by doing the following:

Console app

using CloudBees.OpenFeature.Provider;
using OpenFeatureSDK = OpenFeature.SDK.OpenFeature;

CloudBeesProvider.Setup("API_KEY_GOES_HERE").Wait();
OpenFeatureSDK.Instance.SetProvider(new CloudBeesProvider());
var client = OpenFeatureSDK.Instance.GetClient();
var myCoolFlag = await client.GetBooleanValue("My_Cool_Flag", false);

AspNetCore app

// Add to service collection/DI setup
builder.Services.AddOpenFeatureCloudBees(options =>
{
    options.ApiKey = builder.Configuration.GetValue<string>("CloudBeeApiKey");
});

// Add to class
public class WeatherForecastController : ControllerBase
{
    [ApiController]
    [Route("[controller]")]
    public class WeatherForecastController : ControllerBase
    {
        private static readonly string[] Summaries = new[]
        {
            "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
        };

        private readonly ILogger<WeatherForecastController> _logger;
        private readonly FeatureClient _flagClient;

        public WeatherForecastController(ILogger<WeatherForecastController> logger, FeatureClient flagClient)
        {
            _logger = logger ?? throw new ArgumentNullException(nameof(logger));
            _flagClient = flagClient ?? throw new ArgumentNullException(nameof(flagClient));
        }

        [HttpGet(Name = "GetWeatherForecast")]
        public async Task<IEnumerable<WeatherForecast>> Get()
        {
            var showAsFahrenheit = await _flagClient.GetBooleanValue("ShowAsFahrenheit", false);
            _logger.LogInformation("Evaluated ShowAsFahrenheit flag as {Value}", showAsFahrenheit);
            return Enumerable.Range(1, 5).Select(index =>
                {
                    var temperature = Random.Shared.Next(-20, 55);
                    return new WeatherForecast
                    {
                        Date = DateTime.Now.AddDays(index),
                        Temperature = showAsFahrenheit ? 32 + (int)(temperature / 0.5556) : temperature,
                        Summary = Summaries[Random.Shared.Next(Summaries.Length)]
                    };
                })
                .ToArray();
        }
    }
