Interface RevocationChecker

Example

// In-memory implementation (for simple cases)
class InMemoryRevocationChecker implements RevocationChecker {
  private revoked = new Set<string>();
  async isRevoked(sessionId: string): Promise<boolean> {
    return this.revoked.has(sessionId);
  }
  revoke(sessionId: string): void {
    this.revoked.add(sessionId);
  }
}

// Redis implementation (for production)
class RedisRevocationChecker implements RevocationChecker {
  constructor(private redis: Redis) {}
  async isRevoked(sessionId: string): Promise<boolean> {
    return (await this.redis.sismember('me2em:revoked', sessionId)) === 1;
  }
}
