Row-Level Security Implementation

-- Comprehensive RLS policies for enterprise applications
-- Enable RLS on sensitive tables
ALTER TABLE profiles ENABLE ROW LEVEL SECURITY;
ALTER TABLE projects ENABLE ROW LEVEL SECURITY;
ALTER TABLE documents ENABLE ROW LEVEL SECURITY;

-- User can only access their own profile
CREATE POLICY "Users can view own profile" ON profiles
    FOR SELECT USING (auth.uid() = user_id);

CREATE POLICY "Users can update own profile" ON profiles
    FOR UPDATE USING (auth.uid() = user_id);

-- Project access based on team membership
CREATE POLICY "Team members can view team projects" ON projects
    FOR SELECT USING (
        user_id IN (
            SELECT user_id FROM team_members 
            WHERE team_id = projects.team_id
        )
    );

CREATE POLICY "Team admins can manage team projects" ON projects
    FOR ALL USING (
        user_id IN (
            SELECT user_id FROM team_members 
            WHERE team_id = projects.team_id AND role = 'admin'
        )
    );

-- Document access with role-based permissions
CREATE POLICY "Document access control" ON documents
    FOR ALL USING (
        CASE
            WHEN is_public THEN true
            WHEN owner_id = auth.uid() THEN true
            WHEN user_id IN (
                SELECT user_id FROM document_shares
                WHERE document_id = documents.id AND permission IN ('read', 'write', 'admin')
            ) THEN true
            ELSE false
        END
    );

Real-time Subscription Patterns

// Advanced real-time subscription management
import { RealtimeChannel } from '@supabase/​supabase-js';

class RealtimeManager {
  private subscriptions: Map<string, RealtimeChannel> = new Map();
  
  subscribeToDataChanges(
    table: string, 
    filter: object, 
    callback: (payload: any) => void
  ): string {
    const subscriptionId = `${table}_${Date.now()}`;
    
    const channel = supabase
      .channel(subscriptionId)
      .on(
        'postgres_changes',
        { 
          event: '*', 
          schema: 'public', 
          table: table,
          filter: filter
        },
        callback
      )
      .subscribe();
    
    this.subscriptions.set(subscriptionId, channel);
    return subscriptionId;
  }
  
  subscribeToUserSpecificData(userId: string) {
    return {
      profile: this.subscribeToDataChanges(
        'profiles',
        { user_id: `eq.${userId}` },
        (payload) => this.handleProfileUpdate(payload)
      ),
      projects: this.subscribeToDataChanges(
        'projects',
        { team_id: `in.(${this.getUserTeamIds(userId).join(',')})` },
        (payload) => this.handleProjectUpdate(payload)
      ),
      notifications: this.subscribeToDataChanges(
        'notifications',
        { user_id: `eq.${userId}` },
        (payload) => this.handleNotification(payload)
      )
    };
  }
  
  unsubscribe(subscriptionId: string) {
    const channel = this.subscriptions.get(subscriptionId);
    if (channel) {
      supabase.removeChannel(channel);
      this.subscriptions.delete(subscriptionId);
    }
  }
