Lovable Crash Course

Supabase is an open-source database service built on PostgreSQL. It provides authentication, data storage, and file storage—perfect for our Lovable integration.

1. Create an Organization & Project

   • Log into Supabase.

   • Create an organization (name it based on your startup or project).

   • Create a new project within that organization.

   • Note your Supabase URL and API key (you’ll need them later).

2. Configure Authentication

   • Navigate to Authentication > Sign In/Sign Up.

   • Enable Email authentication.

   • Turn off Confirm Email (since we don’t have an email provider set up yet).

Now, let’s set up a project in Lovable.

1. Start with a Fresh Blank Project

   • Open Lovable and create a new project.

   • Keep your first prompt simple: “Create a blank project”.

   • Lovable will generate the basic structure for your app.

2. Connect Supabase to Lovable

   • In Lovable, navigate to the database settings.

   • Enter your Supabase project URL and API key.

   • Click Connect to link your Lovable project to Supabase.

1. Create a Navigation Bar with a Login Button

   • Add a nav bar at the top of your project.

   • Include a Login button that redirects users to a login page.

2. Apply SQL Changes for Authentication

   • Lovable will generate SQL for Supabase to handle authentication.

   • Click Apply Changes to execute the SQL commands.

1. Customize the UI

   • Open the Edit Tool in Lovable.

   • Click on UI elements (e.g., buttons) to modify styles.

   • Ensure all text is visible (e.g., black text on white backgrounds).

1. Create a Test Account

   • Use the Sign Up form to create a new user.

   • Verify that login and logout workflows function correctly.

2. Redirect Users to a Dashboard After Login

   • Modify the authentication flow to send users to a dashboard after login.

1. Set Up a Notes Table in Supabase

   • Use Lovable to generate SQL for a Notes table.

   • Ensure it has user ID and content fields.

   • Click Apply Changes to create the table.

2. Build the Notes UI

   • Add a table to display notes on the dashboard.

   • Include an input field and buttons for CRUD operations.

     CRUD create, read, update and delete

3. Test CRUD Operations

   • Add a new note.

   • Edit an existing note.

   • Delete a note.

   • Verify notes persist in Supabase.

1. Identify Errors

   • If an issue arises, enable Chat Mode.

   • Lovable will analyze Supabase logs and TypeScript errors.

2. Apply Fixes

   • Review Lovable’s debugging suggestions.

   • Apply fixes as needed.

You’ve:

• Set up Supabase and Lovable.

• Implemented authentication.

• Built a dashboard with CRUD functionality for notes.

• Learned how to debug issues effectively.
