FASTEST way to get started with Next.js and Supabase in 2024

Introduction

In this tutorial, you'll learn how to quickly set up a Next.js application integrated with Supabase. This powerful combination allows you to create modern web applications with features like user authentication, real-time data updates, and more. By following these steps, you will have a functional to-do app up and running in under 10 minutes.

Step 1: Create a New Next.js App

1. Open your terminal.
2. Run the following command to create a new Next.js application using the Supabase template:

   npx create-next-app -e with-supabase
   

3. This command sets up your Next.js app pre-configured for server-side, cookie-based authentication with Supabase.

Step 2: Set Up Your Supabase Project

1. Go to the Supabase website: Supabase.
2. Create a new project if you haven’t already.
3. Once your project is created, note the API keys and database URL provided in your Supabase dashboard.

Step 3: Configure Supabase Client

1. In your Next.js project, create a file to set up the Supabase client.
2. You can do this by creating a file named supabaseClient.js in your project’s root directory.
3. Add the following code to initialize the Supabase client:

   import { createClient } from '@supabase/supabase-js';
   
   const supabaseUrl = 'YOUR_SUPABASE_URL';
   const supabaseAnonKey = 'YOUR_SUPABASE_ANON_KEY';
   
   export const supabase = createClient(supabaseUrl, supabaseAnonKey);
   

   • Replace YOUR_SUPABASE_URL and YOUR_SUPABASE_ANON_KEY with the actual values from your Supabase project.

Step 4: Implement Authentication

1. Use Supabase's built-in authentication methods for user sign-up and login.
2. Create functions in your application to handle user registration and login:

   const signUp = async (email, password) => {
       const { user, error } = await supabase.auth.signUp({ email, password });
       // Handle user and error as needed
   };
   
   const signIn = async (email, password) => {
       const { user, error } = await supabase.auth.signIn({ email, password });
       // Handle user and error as needed
   };
   

3. Integrate these functions into your app's UI.

Step 5: Set Up Real-Time Data Updates

1. Use Supabase's real-time capabilities to listen for changes in your database.
2. Set up a subscription to a specific table:

   const subscription = supabase
       .from('your_table_name')
       .on('INSERT', payload => {
           console.log('New record!', payload);
       })
       .subscribe();
   

3. Replace your_table_name with the actual name of your database table.

Conclusion

You have now successfully set up a Next.js app with Supabase, complete with user authentication and real-time data updates. This foundational setup will allow you to expand your application with more features such as task management and AI functionalities. For further development, explore more advanced features of Supabase and Next.js, and consider implementing AI vector embedding for enhanced capabilities. Happy coding!
