Step 1: Set Up a New Project in Supabase

• • Go to the Supabase website and sign up or log in if you already have an account.
  • Create a new project by clicking on "New Project."
  • Fill in the required details including the project name, database password, and the region closest to you.
  • Click on "Create new project" to complete the setup.

Step 2: Configure Database Tables

• • Once your project is created, navigate to the "Table Editor" in the Supabase dashboard.
  • Click on "New Table" and fill in the details for your users table. Usually, you'll need columns for id, email, password, and any other user-specific fields you require.
  • Make sure the id column is set as the primary key and is unique for each user.
  • Save the table configuration to finalize these columns.

Step 3: Enable Authentication

• • Navigate to the "Authentication" tab in the Supabase dashboard.
  • Go to the "Settings" tab within Authentication and enable email/password authentication.
  • You can configure additional options like email confirmations and password recovery emails from this section.

Step 4: Integrate Supabase Auth with Your Application

• • First, install the Supabase client for your project. If you’re using Node.js, you can do so using: npm install @supabase/supabase-js
  • Next, initialize the Supabase client with your project URL and public API key, which can be found in the Supabase dashboard under "Settings" > "API". Here's a basic example:

          import { createClient } from '@supabase/supabase-js';
    
      const supabaseUrl = 'https://your-project.supabase.co';
      const supabaseKey = 'public-anon-key';
      const supabase = createClient(supabaseUrl, supabaseKey);
      </pre>
    
      

Step 5: Create User Registration Form

• • In your application, create a registration form with fields for email and password.
  • On form submission, call the `signUp` method of the Supabase client. Example:

          const { user, error } = await supabase.auth.signUp({
              email: '[email protected]',
              password: 'password',
          });
          

  • Handle any errors or success messages accordingly in your application.

Step 6: Create User Login Form

• • Similarly, create a login form with fields for email and password.
  • On form submission, call the `signIn` method of the Supabase client. Example:

          const { user, error } = await supabase.auth.signIn({
              email: '[email protected]',
              password: 'password',
          });
          

  • Handle errors and store the user session details upon successful login.

Step 7: Handle User Sessions

• • Supabase provides a way to handle sessions. You can check if a user is logged in with:

          const session = supabase.auth.session();
          

  • You can also set up a listener to handle session changes:

          supabase.auth.onAuthStateChange((event, session) => {
              // Handle session changes
          });
          

Step 8: Implement Email Confirmations (Optional)

• • If you enabled email confirmations in Step 3, make sure you handle the confirmation URL in your application.
  • Check for a `confirmation_sent_at` timestamp in your users table to confirm the user's email status.

Step 9: Deploy and Test Your Application

• • Deploy your application using your preferred hosting service.
  • Test the registration and login functionalities to ensure everything is working as expected.

Step 10: Monitor and Maintain

• • Regularly check the Supabase dashboard for any issues or updates.
  • Monitor user activity and manage your database as your application grows.
