Step 4: Set Up Your Database

Create tables using Supabase SQL editor:

CREATE TABLE profiles (
  id UUID REFERENCES auth.users PRIMARY KEY,
  username TEXT UNIQUE,
  full_name TEXT,
  avatar_url TEXT,
  created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
);

-- Enable Row Level Security
ALTER TABLE profiles ENABLE ROW LEVEL SECURITY;

-- Users can only view/edit their own profile
CREATE POLICY "Users can view own profile"
  ON profiles FOR SELECT
  USING (auth.uid() = id);

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

Step 5: Configure File Storage

1. Go to Storage in Supabase
2. Create a bucket (e.g., "avatars")
3. Set public or private access
4. Add storage policies:

-- Allow authenticated users to upload
CREATE POLICY "Users can upload avatars"
  ON storage.objects FOR INSERT
  WITH CHECK (bucket_id = 'avatars' AND auth.role() = 'authenticated');

Real-Time Updates

See changes instantly:

// Supabase real-time subscription
const subscription = supabase
  .channel('clients')
  .on('postgres_changes',
    { event: '*', schema: 'public', table: 'clients' },
    (payload) => {
      // Update UI automatically
      handleClientChange(payload);
    }
  )
  .subscribe();

Security Best Practices

Row Level Security (RLS)

Ensure users only access their data:

-- Users can only see clients they created
CREATE POLICY "Users view own clients"
  ON clients FOR SELECT
  USING (auth.uid() = user_id);

-- Users can only edit clients they created
CREATE POLICY "Users edit own clients"
  ON clients FOR UPDATE
  USING (auth.uid() = user_id);

-- Users can only delete clients they created
CREATE POLICY "Users delete own clients"
  ON clients FOR DELETE
  USING (auth.uid() = user_id);

API Key Security

Key Type	Use Case	Exposure
Anon Key	Frontend client	Safe to expose
Service Role Key	Backend only	Never expose

Storage Security

Protect file uploads:

-- Limit file types
CREATE POLICY "Only images allowed"
  ON storage.objects FOR INSERT
  WITH CHECK (
    bucket_id = 'avatars'
    AND (storage.extension(name) = 'png'
         OR storage.extension(name) = 'jpg'
         OR storage.extension(name) = 'jpeg')
  );

-- Limit file size (in application code)
const MAX_FILE_SIZE = 5 * 1024 * 1024; // 5MB

  return new Response(JSON.stringify({ success: true }))
})

Database Functions

Create reusable SQL functions:

CREATE OR REPLACE FUNCTION get_user_stats(user_uuid UUID)
RETURNS JSON AS $$
  SELECT json_build_object(
    'total_clients', (SELECT COUNT(*) FROM clients WHERE user_id = user_uuid),
    'total_projects', (SELECT COUNT(*) FROM projects WHERE user_id = user_uuid),
    'revenue', (SELECT COALESCE(SUM(amount), 0) FROM invoices WHERE user_id = user_uuid)
  );
$$ LANGUAGE SQL;

Scheduled Jobs
