Login With Any Platform in React With Supabase (Discord, Google, Facebook, and More!)

Step-by-Step Tutorial: Implementing Login System with Supabase and Discord Integration

1. Setting up Supabase Project:

   • Go to Superbase.com and click on "Start your project" in the top right corner.
   • Sign in and authenticate to access app.superbase.com.
   • Create a new project and select the region closest to you (e.g., West Coast).
   • Navigate to the authentication section by clicking on the people icon on the left and then go to settings under configuration.

2. Configuring Supabase for OAuth applications:

   • Set the success route to https://localhost:3000/success in the settings.
   • Obtain the Supabase URL and project API Keys from the API section in the settings.

3. Setting up Discord Integration:

   • Go to discord.com/developers/applications to create a new Discord application.
   • Note down the client ID and client secret provided by Discord.
   • Configure the Discord integration in Supabase authentication settings by adding the client ID, client secret, and redirect URL.

4. Enabling Login Providers:

   • Follow a similar process for other providers like GitHub or Azure if needed by adding their client ID, client secret, and redirect URL.

5. Creating a React Application:

   • Open Visual Studio Code and create a new React app by running npx create-react-app client.
   • Install necessary packages using npm install.
     • @supabase/auth-ui-react
     • @supabase/supabase-js
     • react-router-dom

6. Setting up Routing in React:

   • Create login and success pages under a folder named 'Pages'.
   • Define routes using BrowserRouter, Routes, and Route components to navigate between pages based on the URL.

7. Implementing Login Component with Supabase:

   • Import createClient, auth, and ThemeProvider from @supabase/supabase-js and @supabase/auth-ui-react.
   • Initialize the Supabase client with the Supabase URL and public key.
   • Use the onAuthStateChange function to handle user authentication events and navigate users to the success URL upon login.

8. Displaying User Information and Logout Button:

   • Copy necessary imports and Supabase initialization to the success page.
   • Use useState and useEffect hooks to fetch and display user data upon successful login.
   • Implement a sign-out function using auth.signOut and navigate users back to the login page.

9. Handling User Authentication State:

   • Check if the user is logged in by verifying the user object retrieved from Supabase.
   • Display user-specific content on the success page and provide a button to navigate back to the login page if the user is not logged in.

10. Testing Login Functionality:

    • Test the login system by signing in with different platforms like Discord.
    • Verify user authentication and data storage in the Supabase authentication section.

11. Exploring Further Integrations:

    • Explore integrating with other platforms by following a similar process for obtaining client IDs, client secrets, and redirect URLs.
    • Customize the authentication UI component provided by Supabase to include additional login providers.

12. Conclusion:

    • Congratulations! You have successfully implemented a login system with Supabase and integrated Discord login in your React application.
