Next.js and Supabase are a popular combination for building modern web applications.
Next.js handles the application layer, while Supabase provides backend services such as PostgreSQL, authentication, storage, and APIs. The connection process is straightforward.
Step 1: Create Your Supabase Project
Create your Supabase project and open the project dashboard. You'll need the project URL and the appropriate API key for your application.
Step 2: Install the Supabase Client
Inside your Next.js project, install the official Supabase JavaScript client. npm install @supabase/supabase-js
Step 3: Add Environment Variables
Create your environment configuration and add the Supabase URL and public key. For a browser-based Next.js application, use the public/publishable key rather than exposing a server-only secret.
Step 4: Create the Supabase Client
Create a small utility file that initializes the Supabase client using those environment variables. Your application can then import this client whenever it needs to communicate with Supabase.
Step 5: Query Your Database
Once the client is configured, you can query tables through Supabase. For example, your application could request a list of products, users, posts, or other records.
Step 6: Deploy the Application
After testing locally, deploy the Next.js application to your production hosting environment. Make sure the same environment variables are configured in production. With Hostwares, you can deploy your Next.js application while keeping your Supabase backend connected through environment variables.
