1. Sign Up and Create a Project

• Sign Up:
  Visit the Supabase website and create an account.

  Once logged in, click on "New Project" in the dashboard. Provide your project details such as the project name, organization, database password, and choose your region. This will provision your PostgreSQL database automatically.

2. Set Up and Connect to Your Database

• Access Database Details:
  After creating your project, navigate to the project settings to find your database URL and API keys.

• Connecting Using Client Libraries:
  You can connect to your Supabase database with various client libraries. For example, in JavaScript:

  JAVASCRIPTCopied
  import { createClient } from '@supabase/supabase-js';
  
  const supabaseUrl = 'https://your-project-url.supabase.co';
  const supabaseKey = 'your-anon-key';
  const supabase = createClient(supabaseUrl, supabaseKey);

  Replace 'your-project-url' and 'your-anon-key' with your actual project URL and API key.

3. Perform Database Operations

• Creating Tables:
  Use the Supabase dashboard's SQL editor to create tables. For instance, to create a users table:

  SQLCopied
  CREATE TABLE users (
    id SERIAL PRIMARY KEY,
    username VARCHAR(100),
    created_at TIMESTAMP DEFAULT NOW()
  );

• Querying Data:
  Once connected, you can perform SQL queries to interact with your data. You can also use Supabase client libraries to query data within your application code.
