feat: integrate Supabase for database operations and migrations
Add support for Supabase database operations, including migrations and queries. Implement new Supabase-related types, actions, and components to handle database interactions. Enhance the prompt system to include Supabase-specific instructions and constraints. Ensure data integrity and security by enforcing row-level security and proper migration practices.

|

The following instructions guide how you should handle database operations in projects.
|
||||
|
||||
CRITICAL: Use Supabase for databases by default, unless specified otherwise.
|
||||
|
||||
IMPORTANT NOTE: Supabase project setup and configuration is handled seperately by the user! ${
|
||||
supabase
|
||||
? !supabase.isConnected
|
||||
? 'You are not connected to Supabase. Remind the user to "connect to Supabase in the chat box before proceeding with database operations".'
|
||||
: !supabase.hasSelectedProject
|
||||
? 'Remind the user "You are connected to Supabase but no project is selected. Remind the user to select a project in the chat box before proceeding with database operations".'
|
||||
: ''
|
||||
: ''
|
||||
}
|
||||
The environment variables for Supabase connection will be available in the project's \`.env\` file.
|
||||
IMPORTANT: Create a .env file if it doesnt exist.
|
||||
NEVER modify any Supabase configuration or \`.env\` files.
|
||||
|
||||
CRITICAL DATA PRESERVATION AND SAFETY REQUIREMENTS:
|
||||
- DATA INTEGRITY IS THE HIGHEST PRIORITY, users must NEVER lose their data
|
||||
- FORBIDDEN: Any destructive operations like \`DROP\` or \`DELETE\` that could result in data loss (e.g., when dropping columns, changing column types, renaming tables, etc.)
|
||||
- FORBIDDEN: Any transaction control statements (e.g., explicit transaction management) such as:
|
||||
- \`BEGIN\`
|
||||
- \`COMMIT\`
|
||||
- \`ROLLBACK\`
|
||||
- \`END\`
|
||||
|
||||
Note: This does NOT apply to \`DO $$ BEGIN ... END $$\` blocks, which are PL/pgSQL anonymous blocks!
|
||||
|
||||
Writing SQL Migrations:
|
||||
CRITICAL: For EVERY database change, you MUST provide TWO actions:
|
||||
1. Migration File Creation:
|
||||
<boltAction type="supabase" operation="migration" filePath="/supabase/migrations/your_migration.sql">
|
||||
/* SQL migration content */
|
||||
</boltAction>
|
||||
|
||||
2. Immediate Query Execution:
|
||||
<boltAction type="supabase" operation="query" projectId="\${projectId}">
|
||||
/* Same SQL content as migration */
|
||||
</boltAction>
|
||||
|
||||
Example:
|
||||
<boltArtifact id="create-users-table" title="Create Users Table">
|
||||
<boltAction type="supabase" operation="migration" filePath="/supabase/migrations/create_users.sql">
|
||||
CREATE TABLE users (
|
||||
id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
|
||||
email text UNIQUE NOT NULL
|
||||
);
|
||||
</boltAction>
|
||||
|
||||
<boltAction type="supabase" operation="query" projectId="\${projectId}">
|
||||
CREATE TABLE users (
|
||||
id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
|
||||
email text UNIQUE NOT NULL
|
||||
);
|
||||
</boltAction>
|
||||
</boltArtifact>
|
||||
|
||||
- IMPORTANT: The SQL content must be identical in both actions to ensure consistency between the migration file and the executed query.
|
||||
- CRITICAL: NEVER use diffs for migration files, ALWAYS provide COMPLETE file content
|
||||
- For each database change, create a new SQL migration file in \`/home/project/supabase/migrations\`
|
||||
- NEVER update existing migration files, ALWAYS create a new migration file for any changes
|
||||
- Name migration files descriptively and DO NOT include a number prefix (e.g., \`create_users.sql\`, \`add_posts_table.sql\`).
|
||||
|
||||
- DO NOT worry about ordering as the files will be renamed correctly!
|
||||
|
||||
- ALWAYS enable row level security (RLS) for new tables:
|
||||
|
||||
<example>
|
||||
alter table users enable row level security;
|
||||
</example>
|
||||
|
||||
- Add appropriate RLS policies for CRUD operations for each table
|
||||
|
||||
- Use default values for columns:
|
||||
- Set default values for columns where appropriate to ensure data consistency and reduce null handling
|
||||
- Common default values include:
|
||||
- Booleans: \`DEFAULT false\` or \`DEFAULT true\`
|
||||
- Numbers: \`DEFAULT 0\`
|
||||
- Strings: \`DEFAULT ''\` or meaningful defaults like \`'user'\`
|
||||
- Dates/Timestamps: \`DEFAULT now()\` or \`DEFAULT CURRENT_TIMESTAMP\`
|
||||
- Be cautious not to set default values that might mask problems; sometimes it's better to allow an error than to proceed with incorrect data
|
||||
|
||||
- CRITICAL: Each migration file MUST follow these rules:
|
||||
- ALWAYS Start with a markdown summary block (in a multi-line comment) that:
|
||||
- Include a short, descriptive title (using a headline) that summarizes the changes (e.g., "Schema update for blog features")
|
||||
- Explains in plain English what changes the migration makes
|
||||
- Lists all new tables and their columns with descriptions
|
||||
- Lists all modified tables and what changes were made
|
||||
- Describes any security changes (RLS, policies)
|
||||
- Includes any important notes
|
||||
- Uses clear headings and numbered sections for readability, like:
|
||||
1. New Tables
|
||||
2. Security
|
||||
3. Changes
|
||||
|
||||
IMPORTANT: The summary should be detailed enough that both technical and non-technical stakeholders can understand what the migration does without reading the SQL.
|
||||
|
||||
- Include all necessary operations (e.g., table creation and updates, RLS, policies)
|
||||
|
||||
Here is an example of a migration file:
|
||||
|
||||
<example>
|
||||
/*
|
||||
# Create users table
|
||||
|
||||
1. New Tables
|
||||
- \`users\`
|
||||
- \`id\` (uuid, primary key)
|
||||
- \`email\` (text, unique)
|
||||
- \`created_at\` (timestamp)
|
||||
2. Security
|
||||
- Enable RLS on \`users\` table
|
||||
- Add policy for authenticated users to read their own data
|
||||
*/
|
||||
|
||||
CREATE TABLE IF NOT EXISTS users (
|
||||
id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
|
||||
email text UNIQUE NOT NULL,
|
||||
created_at timestamptz DEFAULT now()
|
||||
);
|
||||
|
||||
ALTER TABLE users ENABLE ROW LEVEL SECURITY;
|
||||
|
||||
CREATE POLICY "Users can read own data"
|
||||
ON users
|
||||
FOR SELECT
|
||||
TO authenticated
|
||||
USING (auth.uid() = id);
|
||||
</example>
|
||||
|
||||
- Ensure SQL statements are safe and robust:
|
||||
- Use \`IF EXISTS\` or \`IF NOT EXISTS\` to prevent errors when creating or altering database objects. Here are examples:
|
||||
|
||||
<example>
|
||||
CREATE TABLE IF NOT EXISTS users (
|
||||
id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
|
||||
email text UNIQUE NOT NULL,
|
||||
created_at timestamptz DEFAULT now()
|
||||
);
|
||||
</example>
|
||||
|
||||
<example>
|
||||
DO $$
|
||||
BEGIN
|
||||
IF NOT EXISTS (
|
||||
SELECT 1 FROM information_schema.columns
|
||||
WHERE table_name = 'users' AND column_name = 'last_login'
|
||||
) THEN
|
||||
ALTER TABLE users ADD COLUMN last_login timestamptz;
|
||||
END IF;
|
||||
END $$;
|
||||
</example>
|
||||
|
||||
Client Setup:
|
||||
- Use \`@supabase/supabase-js\`
|
||||
- Create a singleton client instance
|
||||
- Use the environment variables from the project's \`.env\` file
|
||||
- Use TypeScript generated types from the schema
|
||||
|
||||
Authentication:
|
||||
- ALWAYS use email and password sign up
|
||||
- FORBIDDEN: NEVER use magic links, social providers, or SSO for authentication unless explicitly stated!
|
||||
- FORBIDDEN: NEVER create your own authentication system or authentication table, ALWAYS use Supabase's built-in authentication!
|
||||
- Email confirmation is ALWAYS disabled unless explicitly stated!
|
||||
|
||||
Row Level Security:
|
||||
- ALWAYS enable RLS for every new table
|
||||
- Create policies based on user authentication
|
||||
- Test RLS policies by:
|
||||
1. Verifying authenticated users can only access their allowed data
|
||||
2. Confirming unauthenticated users cannot access protected data
|
||||
3. Testing edge cases in policy conditions
|
||||
|
||||
Best Practices:
|
||||
- One migration per logical change
|
||||
- Use descriptive policy names
|
||||
- Add indexes for frequently queried columns
|
||||
- Keep RLS policies simple and focused
|
||||
- Use foreign key constraints
|
||||
|
||||
TypeScript Integration:
|
||||
- Generate types from database schema
|
||||
- Use strong typing for all database operations
|
||||
- Maintain type safety throughout the application
|
||||
|
||||
IMPORTANT: NEVER skip RLS setup for any table. Security is non-negotiable!
