Here are ten ways Supabase differs from other hosted Postgres solutions and the code changes needed to move from an Express.js backend using Postgres directly to Supabase:

1. Authentication:

   • Supabase provides built-in authentication functionality, including user registration, login, and JWT-based authentication.
   • Code change: Remove custom authentication logic from Express.js and utilize Supabase's authentication API endpoints and libraries.

2. Authorization:

   • Supabase offers row-level security (RLS) and policies for fine-grained access control to database tables.
   • Code change: Implement RLS policies in Supabase and remove custom authorization checks from Express.js routes.

3. Real-time subscriptions:

   • Supabase supports real-time subscriptions using WebSockets, allowing clients to receive live updates from the database.
   • Code change: Replace manual polling or server-sent events in Express.js with Supabase's real-time subscription functionality.

4. Database migrations:

   • Supabase provides a CLI tool for managing database migrations, making it easier to version control and deploy schema changes.
   • Code change: Use Supabase's migration tool instead of manually running SQL scripts or using a separate migration library.

5. API auto-generation:

   • Supabase automatically generates RESTful API endpoints based on your database schema.
   • Code change: Remove custom API routes from Express.js and utilize Supabase's auto-generated API endpoints.

6. Storage:

   • Supabase offers built-in storage functionality for handling file uploads and serving static assets.
   • Code change: Replace custom file upload handling in Express.js with Supabase's storage API and integrate it with your application.

7. Functions:

   • Supabase supports serverless functions, allowing you to execute custom logic in response to events or API calls.
   • Code change: Move relevant server-side logic from Express.js to Supabase Functions and trigger them as needed.

8. Database GUI:

   • Supabase provides a web-based GUI for managing and querying the database, eliminating the need for a separate database management tool.
   • Code change: Utilize Supabase's GUI for database management tasks instead of using a separate tool or writing manual queries.

9. Realtime dashboard:

   • Supabase offers a realtime dashboard that provides insights into database queries, subscriptions, and performance metrics.
   • Code change: Monitor and analyze database activity using Supabase's realtime dashboard instead of implementing custom monitoring solutions.

10. Client libraries:

    • Supabase provides client libraries for
