How to connect Supabase to Vercel?

 

Step 1: Sign Up for Supabase

 

Before connecting Supabase to Vercel, you need to have a Supabase account and a project created.

1. Go to the Supabase website.
2. Sign up for an account or log in if you already have one.
3. After logging in, create a new project. Note the API URL and anon key, as you'll need them later.

 

Step 2: Set Up Supabase Client in Your Vercel App

 

You need to integrate Supabase with your Vercel application.

• Start by installing the Supabase client in your project. Assuming that you have a JavaScript or TypeScript-based application, use npm or yarn to install the library:

npm install @supabase/supabase-js

or

yarn add @supabase/supabase-js

• Next, create a file (e.g., supabaseClient.js) to configure 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 your actual Supabase project URL and anon key.

 

Step 3: Deploy Application to Vercel

 

Deploy your application to Vercel using either the Vercel CLI or by connecting your GitHub/GitLab repository.

• If using Vercel CLI, run the following command in the root of your project:

vercel

• If you prefer to connect your repository:

• Go to Vercel Dashboard.

• Click on "New Project" and import your Git repository.

• Follow the setup instructions to deploy your application.

 

Step 4: Set Environment Variables in Vercel

 

Environment variables store your Supabase credentials securely.

• Go to your Vercel Dashboard and click on your newly deployed project.

• Navigate to the "Settings" tab.

• Under "Environment Variables", add the following:

• Key: NEXT_PUBLIC_SUPABASE_URL

• Value: <YOUR_SUPABASE_URL>

• Key: NEXT_PUBLIC_SUPABASE_ANON_KEY

• Value: <YOUR_SUPABASE_ANON_KEY>

• Ensure that these variables are matched with those you used in your Supabase client configuration.

 

Step 5: Verify the Connection

 

By now, your Vercel app should be connected to Supabase.

• Use the Supabase client in your project to perform database operations like fetching data or inserting new records to confirm the connection.

import { supabase } from './supabaseClient';

const fetchData = async () => {
  const { data, error } = await supabase
    .from('your_table_name')
    .select('*');

  if (error) console.log('Error:', error);
  else console.log('Data:', data);
};

fetchData();

Modify 'your_table_name' to an actual table in your Supabase database.

By following these steps, you should have successfully connected Supabase to your Vercel project. Always ensure your connection credentials remain secure and never push them to a public repository.
