Core API Architecture

Authentication Middleware

// Authelia ForwardAuth integration
interface AutheliaUser {
  id: string;
  name: string;
  email: string;
  username: string;
  groups: string[];
  role: 'ADMIN' | 'TOURNAMENT_ORGANIZER' | 'PARTICIPANT';

  // Extract user from Authelia ForwardAuth headers
  const remoteUser = req.headers['remote-user'] as string;
  const remoteEmail = req.headers['remote-email'] as string;
  const remoteName = req.headers['remote-name'] as string;
  const remoteGroups = req.headers['remote-groups'] as string;

  if (remoteUser && remoteEmail) {
    // Map Authelia groups to tournament roles
    const role = mapUserRole(remoteGroups ? remoteGroups.split(',') : ['users']);
    
    const user: AutheliaUser = {
      id: remoteUser,
      name: remoteName || remoteEmail,
      email: remoteEmail,
      username: remoteUser,
      groups: remoteGroups ? remoteGroups.split(',') : ['users'],
      role
    };

    req.user = user;
    return next();
  }

  res.status(401).json({ error: 'Authentication required' });
};

Tournament Management System

// Advanced tournament bracket generation

    switch (tournamentType) {
      case 'SINGLE_ELIMINATION':

        return this.generateSwissSystem(participants);
    }
  }
  
  async updateMatchResult(matchId: string, result: MatchResult) {
    // Validate match result and update bracket
    const match = await this.validateMatchResult(matchId, result);
    const updatedMatch = await this.processMatchResult(match, result);
    
    // Emit real-time update via Socket.io
    this.io.to(`tournament_${match.tournamentId}`)

const calculateBracketSize = (participants: number, type: TournamentType): number => {
  switch (type) {
    case 'SINGLE_ELIMINATION':
    case 'DOUBLE_ELIMINATION':
      return Math.pow(2, Math.ceil(Math.log2(participants))); // Next power of 2
    case 'ROUND_ROBIN':
      return participants; // Everyone plays everyone
    case 'SWISS_SYSTEM':
      return participants; // Pairing-based system
    default:
      return participants;
  }
};

  // Validate permissions
  if (!canUpdateMatch(user, match)) {
    throw new Error('Not authorized to update this match');
  }
  
  // Process result and update bracket
  const updatedMatch = await processMatchResult(match, result);
  
  // Generate next round matches if bracket round completed
  if (await isRoundComplete(match.tournamentId, match.roundNumber)) {
    await generateNextRoundMatches(match.tournamentId);
  }
  
  return updatedMatch;
};
