Key Components

Connection Management (useSupabase Hook)

• Handles Supabase client initialization and connection management
• Implements multiple table discovery strategies
• Provides unified interface for all database operations

Table Discovery System

The application uses a sophisticated multi-method approach to discover tables:

1. OpenAPI Schema Parsing: Analyzes Supabase's auto-generated OpenAPI schema
2. Endpoint Testing: Tests common table name patterns
3. PostgREST Introspection: Attempts to use PostgREST's introspection capabilities
4. Brute Force Discovery: Systematic testing of potential table names

Data Type System

• Automatic Type Inference: Determines data types from sample data
• Smart Formatting: Context-aware display formatting for different data types
• Type Conversion: Handles conversion between display and storage formats

🚀 Getting Started

Prerequisites

• Node.js 18+ and npm
• A Supabase project with database access
• Supabase URL and API key (anon or service_role)

Installation

1. Clone the repository

   git clone <repository-url>
   cd supabase-db-manager

2. Install dependencies

   npm install

3. Start the development server

   npm run dev

4. Open your browser Navigate to http://localhost:5173

Configuration

1. Get your Supabase credentials

   • Go to your Supabase project dashboard
   • Navigate to Settings → API
   • Copy your Project URL and API key

2. Connect to your database

   • Enter your Supabase URL (e.g., https://your-project.supabase.co)
   • Enter your API key (anon key for read-only, service_role for full access)
   • Optionally provide a connection name for easy identification

📖 Usage Guide

Connecting to a Database

1. Launch the application
2. Enter your Supabase URL and API key
3. Click "Connect to Database"

Managing Table Data

1. Select a table from the sidebar
2. View, edit, or delete existing records
3. Add new records using the "Add Row" button
4. Use search functionality to find specific data
5. Navigate through pages for large datasets

Exporting Data

1. Click "Export" in the sidebar
2. Select tables to export
3. Choose format (JSON or SQL)
4. Configure options (schema, data)
5. Click "Export Database" to download

Importing Data

1. Click "Import" in the sidebar
2. Upload a JSON or SQL file
3. Review the validation results
