RBAC Service

// src/services/rbac/rbac.service.ts
import { User } from '../../models/user.model';
import { ROLES } from '../../lib/rbac/roles';
import { Permission } from '../../lib/rbac/permissions';

export class RBACService {
  async getUserPermissions(userId: string): Promise<Permission[]> {
    const user = await prisma.user.findUnique({
      where: { id: userId },
      include: {
        roles: true,
        customPermissions: true,
      },
    });

    if (!user) {
      return [];
    }

    const permissions = new Set<Permission>();

    // Add role permissions
    for (const role of user.roles) {
      const roleDef = ROLES[role.name];
      if (roleDef) {
        roleDef.permissions.forEach(p => permissions.add(p));
      }
    }

    // Add custom permissions
    user.customPermissions.forEach(p => {
      if (p.granted) {
        permissions.add(p.permission as Permission);
      } else {
        permissions.delete(p.permission as Permission);
      }
    });

    return Array.from(permissions);
  }

  async hasPermission(userId: string, permission: Permission): Promise<boolean> {
    const permissions = await this.getUserPermissions(userId);
    return permissions.includes(permission);
  }

  async hasAnyPermission(userId: string, permissions: Permission[]): Promise<boolean> {
    const userPermissions = await this.getUserPermissions(userId);
    return permissions.some(p => userPermissions.includes(p));
  }

  async hasAllPermissions(userId: string, permissions: Permission[]): Promise<boolean> {
    const userPermissions = await this.getUserPermissions(userId);
    return permissions.every(p => userPermissions.includes(p));
  }
}

export const rbac = new RBACService();

Permission Middleware

// src/middleware/rbac.middleware.ts
import { Request, Response, NextFunction } from 'express';
import { rbac } from '../services/rbac/rbac.service';
import { Permission } from '../lib/rbac/permissions';

export function requirePermission(...permissions: Permission[]) {
  return async (req: Request, res: Response, next: NextFunction) => {
    const userId = req.user?.id;

    if (!userId) {
      return res.status(401).json({ error: 'Authentication required' });
    }

    const hasPermission = await rbac.hasAnyPermission(userId, permissions);

    if (!hasPermission) {
      // Audit failed access attempt
      await auditLog.create({
        action: 'PERMISSION_DENIED',
        actor: userId,
        resource: req.path,
        metadata: { requiredPermissions: permissions },
      });

      return res.status(403).json({
        error: 'Permission denied',
        required: permissions,
      });
    }

    next();
  };
}

// Usage in routes
router.get('/contacts',
  requirePermission('contacts:read'),
  contactController.list
);

router.post('/contacts',
  requirePermission('contacts:create'),
  contactController.create
);

router.delete('/contacts/:id',
  requirePermission('contacts:delete'),
  contactController.delete
);

router.post('/search/bulk',
  requirePermission('search:bulk', 'search:advanced'),
  searchController.bulkSearch
);

Team-Based Access Control

// src/services/rbac/team-access.ts
export class TeamAccessService {
  async getAccessibleContacts(
    userId: string,
    teamId: string
  ): Promise<string[]> {
    // Check user's team membership
    const membership = await prisma.teamMember.findFirst({
      where: { userId, teamId },
      include: { team: true },
    });

    if (!membership) {
      return [];
    }

    // Build access scope
    const accessScope = await this.buildAccessScope(userId, membership);

    // Return contact IDs user can access
    const contacts = await prisma.contact.findMany({
      where: accessScope,
      select: { id: true },
    });

    return contacts.map(c => c.id);
  }

  private async buildAccessScope(
    userId: string,
    membership: TeamMembership
  ): Promise<any> {
    // Team admins can see all team contacts
    if (membership.role === 'admin' || membership.role === 'manager') {
      return { teamId: membership.teamId };
    }

    // Regular members see own contacts + shared
    return {
      OR: [
        { ownerId: userId },
        { sharedWith: { some: { userId } } },
        { teamId: membership.teamId, isPublic: true },
      ],
    };
  }
}

// Middleware for team-scoped access
export function requireTeamAccess(resourceType: string) {
  return async (req: Request, res: Response, next: NextFunction) => {
    const userId = req.user?.id;
    const resourceId = req.params.id;

    const hasAccess = await teamAccess.canAccessResource(
      userId,
      resourceType,
      resourceId
    );

    if (!hasAccess) {
      return res.status(403).json({
        error: 'You do not have access to this resource',
      });
    }

    next();
  };
}

API Key Scoping

// src/lib/rbac/api-key-scope.ts
interface ApiKeyScope {
  permissions: Permission[];
  rateLimit: number;
  ipAllowlist?: string[];
  expiresAt?: Date;
}

export async function createScopedApiKey(
  userId: string,
  scope: ApiKeyScope
): Promise<string> {
  // Validate user has the permissions they're granting
  const userPermissions = await rbac.getUserPermissions(userId);
  const invalidPermissions = scope.permissions.filter(
    p => !userPermissions.includes(p)
  );

  if (invalidPermissions.length > 0) {
    throw new Error(`Cannot grant permissions you don't have: ${invalidPermissions.join(', ')}`);
  }

  // Generate key
  const apiKey = generateSecureKey();

  // Store with scope
  await prisma.apiKey.create({
    data: {
      key: hashApiKey(apiKey),
      userId,
      permissions: scope.permissions,
      rateLimit: scope.rateLimit,
      ipAllowlist: scope.ipAllowlist,
      expiresAt: scope.expiresAt,
    },
  });

  return apiKey;
}

// Middleware to enforce API key scope
export function enforceApiKeyScope(requiredPermissions: Permission[]) {
  return async (req: Request, res: Response, next: NextFunction) => {
    const apiKey = req.headers['x-api-key'];

    if (!apiKey) {
      return res.status(401).json({ error: 'API key required' });
    }

    const keyRecord = await prisma.apiKey.findFirst({
      where: { key: hashApiKey(apiKey as string) },
    });

    if (!keyRecord) {
      return res.status(401).json({ error: 'Invalid API key' });
    }

    // Check expiration
    if (keyRecord.expiresAt && new Date() > keyRecord.expiresAt) {
      return res.status(401).json({ error: 'API key expired' });
    }

    // Check IP allowlist
    if (keyRecord.ipAllowlist?.length > 0) {
      const clientIp = req.ip;
      if (!keyRecord.ipAllowlist.includes(clientIp)) {
        return res.status(403).json({ error: 'IP not allowed' });
      }
    }

    // Check permissions
    const hasPermission = requiredPermissions.every(
      p => keyRecord.permissions.includes(p)
    );

    if (!hasPermission) {
      return res.status(403).json({
        error: 'API key lacks required permissions',
        required: requiredPermissions,
      });
    }

    next();
  };
}

Admin Dashboard

// src/routes/admin/rbac.ts
router.get('/users/:id/permissions',
  requirePermission('admin:users'),
  async (req, res) => {
    const permissions = await rbac.getUserPermissions(req.params.id);
    res.json({ permissions });
  }
);

router.post('/users/:id/roles',
  requirePermission('admin:roles'),
  async (req, res) => {
    const { roles } = req.body;
    await rbac.assignRoles(req.params.id, roles);
    res.json({ success: true });
  }
);

router.get('/audit/access-denied',
  requirePermission('admin:audit'),
  async (req, res) => {
    const logs = await prisma.auditLog.findMany({
      where: { action: 'PERMISSION_DENIED' },
      orderBy: { createdAt: 'desc' },
      take: 100,
    });
    res.json({ logs });
  }
);
