Flare.Extensions.Configuration

Configuration provider for Flare feature flag management system. Enables loading feature flags as configuration values with support for auto-reload and multiple environments.

Installation

dotnet add package Flare.Extensions.Configuration

Quick Start

var builder = WebApplication.CreateBuilder(args);

// Add Flare configuration provider
builder.Configuration.AddFlareConfiguration();

// Add the background service that polls for flag updates
builder.Services.AddFlareBackgroundService(options =>
{
    options.ServerUrl = "https://flare.example.com";
    options.ApiKey = "your-api-key";
    options.ScopeAlias = "production";
    options.ReloadInterval = TimeSpan.FromMinutes(5);
});

var app = builder.Build();

// Access feature flags through IConfiguration
var isEnabled = app.Configuration.GetValue<bool>("FeatureFlags:new-feature");

Configuration from appsettings.json

You can also configure the provider using a configuration section:

{
  "Flare": {
    "ServerUrl": "https://flare.example.com",
    "ApiKey": "your-api-key",
    "ScopeAlias": "production",
    "ReloadInterval": "00:05:00",
    "FeatureFlagSection": "FeatureFlags"
  }
}

builder.Configuration.AddFlareConfiguration();
builder.Services.AddFlareBackgroundService(builder.Configuration, "Flare");

Configuration Options

Option	Type	Default	Description
`ServerUrl`	string	Required	Flare server URL
`ApiKey`	string	Required	Project API key
`ScopeAlias`	string	Required	Scope/environment (e.g., "production", "staging")
`ReloadInterval`	TimeSpan	`TimeSpan.Zero`	Interval for polling flag updates
`FeatureFlagSection`	string	`"FeatureFlags"`	Configuration section prefix for flags

How It Works

AddFlareConfiguration() registers a configuration provider that listens for flag updates
AddFlareBackgroundService() starts a hosted service that periodically fetches flags from the Flare API
Flags are exposed under the configured section (default: FeatureFlags:{flag-key})
Configuration change tokens allow IOptionsSnapshot<T> and IOptionsMonitor<T> to react to updates

Features

ASP.NET Core integration - Works seamlessly with IConfiguration
Auto-reload - Background service periodically refreshes feature flags
Multi-environment - Support for dev, staging, production scopes via ScopeAlias
Change notifications - Triggers IOptionsMonitor<T> callbacks on flag updates
Logging support - Built-in logging for monitoring reload operations
