nest-feature-guard/dist/feature-flag-cache.interface.d.ts

A powerful, NestJS-first feature flag guard and decorator library with Redis caching support. Perfect for implementing feature toggles, A/B testing, gradual rollouts, and user-specific feature access control.

export interface SetFeatureFlagOptions {
    flag: string;
    enabled: boolean;
    userIds?: string[];
}
export interface FeatureGuardStore {
    setFeatureFlag(options: SetFeatureFlagOptions): Promise<void>;
    getFeature(flag: string): Promise<{
        enabled: boolean;
        userIds?: string[];
    } | null>;
    hasFeatureFlag(flag: string, userId: string): Promise<boolean>;
}
