Step 1: Set Up a Supabase Project
 

• Visit the Supabase website and sign up for an account if you don't already have one.
• Once logged in, create a new project and give it a name related to order tracking.
• Select a database password and remember it, as you'll need it later.

 
Step 2: Configure Database
 

• In the Supabase dashboard, navigate to the SQL editor to create tables for order tracking.
• Create a table for orders with fields such as order_id, customer_name, order_status, created_at, updated\_at, etc.
• Enter the following SQL command to create the 'orders' table:

        CREATE TABLE orders (
          order\_id SERIAL PRIMARY KEY,
          customer\_name VARCHAR(100) NOT NULL,
          order\_status VARCHAR(50) NOT NULL,
          created\_at TIMESTAMPTZ DEFAULT NOW(),
          updated\_at TIMESTAMPTZ DEFAULT NOW()
        );
      

• Click the "RUN" button to execute the command.

 
Step 3: Insert Initial Data
 

• Use the SQL editor to insert some initial data into the 'orders' table:

        INSERT INTO orders (customer_name, order_status) 
        VALUES 
        ('John Doe', 'Pending'),
        ('Jane Smith', 'Shipped');
      

• Execute the command by clicking the "RUN" button.

 
Step 4: Set Up API
 

• Supabase provides an auto-generated API for your database. Navigate to the "API" section to get your API URL and key.
• Make sure you have your Supabase Project URL and public API key on hand for the next steps.

 
Step 5: Frontend Setup
 

• Initialize a new front-end project using a framework like React, Vue, or plain HTML/CSS/JS. For simplicity, let's use React:
• Run:

        npx create-react-app order-tracking
        cd order-tracking
      

• Install the Supabase client for JavaScript:

        npm install @supabase/supabase-js
      

 
Step 6: Connect to Supabase
 

• Create a new file inside the src directory named supabaseClient.js and add the following code:

        import { createClient } from '@supabase/supabase-js';
  
    const supabaseUrl = 'YOUR_SUPABASE_URL';
    const supabaseKey = 'YOUR_SUPABASE_ANON\_KEY';
    const supabase = createClient(supabaseUrl, supabaseKey);
  
    export default supabase;
  </pre>
  
    

• Replace YOUR_SUPABASE_URL and YOUR_SUPABASE_ANON\_KEY with the values gotten from the Supabase dashboard.

 
Step 7: Fetch Orders Data
 

• In src/App.js, import the Supabase client and modify the App component to fetch and display orders:

        import React, { useEffect, useState } from 'react';
        import supabase from './supabaseClient';
  
    function App() {
      const [orders, setOrders] = useState([]);
  
      useEffect(() => {
        const fetchOrders = async () => {
          let { data: orders, error } = await supabase
            .from('orders')
            .select('\*');
  
          if (error) console.error('Error fetching orders:', error);
          else setOrders(orders);
        };
  
        fetchOrders();
      }, []);
  
      return (
        <div className="App">
          <h1>Order Tracking</h1>
          <ul>
            {orders.map(order => (
              <li key={order.order\_id}>
                {order.customer_name}: {order.order_status}
              </li>
            ))}
          </ul>
        </div>
      );
    }
  
    export default App;
  </pre>
  
    

 
Step 8: Deployment
 

• Host your frontend application using services like Vercel, Netlify, or GitHub Pages.
• Make sure to set environment variables securely in the deployment service's settings.
• Test the application to ensure data fetches correctly and updates in real-time if necessary.

 
Conclusion
 

• You've now set up a basic order tracking system using Supabase and React. For more advanced features, consider adding authentication, more detailed order statuses, and real-time updates with Supabase's subscriptions feature.
