feature-flags
Rationale
Feature flags enable safe deployments, gradual rollouts, A/B testing, and quick rollback capabilities. Without proper feature flag patterns, teams risk deploying incomplete features or cannot respond quickly to production issues. These patterns provide a robust, maintainable approach to feature management in Razor Pages applications.
Patterns
Pattern 1: Configuration-Based Feature Flags
Use appsettings.json for simple feature toggles with environment-specific overrides.
// appsettings.json
{
"FeatureManagement": {
"NewDashboard": false,
"BetaFeature": false,
"DarkMode": true,
"PaymentV2": {
"EnabledFor": [
