  • Protected Buckets: Specific access rules can be set to control read/write permissions granularly.

6. Initializing the Supabase Client in Your Application

a. Install Supabase Client Libraries

Depending on your application's framework, install the appropriate Supabase client library:

For JavaScript/TypeScript:

npm install @supabase/supabase-js

For Flutter:

flutter pub add supabase_flutter

b. Initialize the Supabase Client

Use the project's URL and Public Anon Key to initialize the Supabase client in your code:

JavaScript/TypeScript Example:


// Import the createClient function
import { createClient } from '@supabase/supabase-js';

// Your Supabase project URL and Anon Key
const supabaseUrl = 'https://your-supabase-project.supabase.co';
const supabaseAnonKey = 'your-public-anon-key';

// Initialize the Supabase client
const supabase = createClient(supabaseUrl, supabaseAnonKey);
  

Python Example:

from supabase import create_client

# Your Supabase project URL and Anon Key
supabase_url = 'https://your-supabase-project.supabase.co'
supabase_key = 'your-public-anon-key'

# Initialize the Supabase client
supabase = create_client(supabase_url, supabase_key)
  

Swift Example:

// Import the Supabase client library
import Supabase

// Initialize the Supabase client
let supabase = SupabaseClient(supabaseURL: URL(string: "https://your-supabase-project.supabase.co")!,
                              supabaseKey: "your-public-anon-key")
  

c. Use Environment Variables for Security

It's a best practice to store your Supabase URL and key in environment variables to enhance security:


// .env file
NEXT_PUBLIC_SUPABASE_URL=https://your-supabase-project.supabase.co
NEXT_PUBLIC_SUPABASE_ANON_KEY=your-public-anon-key

// Initialization in your code
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL;
const supabaseAnonKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY;

const supabase = createClient(supabaseUrl, supabaseAnonKey);
  

7. Configuring Client Options

a. Customize Client Behavior

Supabase allows customization of the client with various options to tailor its behavior:


// Import the createClient function
import { createClient } from '@supabase/supabase-js';

// Define configuration options
const options = {
  db: {
    schema: 'public', // Default schema
  },
  auth: {
    autoRefreshToken: true,
    persistSession: true,
    detectSessionInUrl: true,
  },
  global: {
    headers: { 'x-my-custom-header': 'my-app-name' },
  },
};

// Initialize the Supabase client with options
const supabase = createClient('https://your-supabase-project.supabase.co', 'your-public-anon-key', options);
  

b. Server-Side Rendering (SSR) Configuration

If your application uses Server-Side Rendering, configure the Supabase client to use cookies for session management:


// Install the Supabase SSR package
npm install @supabase/ssr

// Initialize with SSR options
import { createClient } from '@supabase/supabase-js';
import { createClient as createSSRClient } from '@supabase/ssr';

const supabase = createSSRClient('https://your-supabase-project.supabase.co', 'your-public-anon-key', {
  cookieOptions: {
    name: 'sb:token',
    lifetime: 60 * 60 * 24 * 7, // 7 days
    path: '/',
    sameSite: 'lax',
    secure: true,
  },
});
  

8. Exploring Additional Features

a. Realtime Subscriptions

Enable real-time functionalities to have your application react instantly to database changes:


// Subscribe to changes in the 'messages' table
supabase
  .from('messages')
  .on('INSERT', payload => {
    console.log('New message:', payload.new);
  })
  .subscribe();
  

b. Edge Functions

Deploy serverless functions to run backend code securely. Edge functions allow you to perform operations that require secure execution environments:


// Example Edge Function
export default async function handler(req, res) {
  // Your secure backend logic here
  res.status(200).json({ message: 'Hello from Edge Function!' });
}
  

c. Monitoring and Analytics

Utilize Supabase's monitoring tools to track your project's performance and usage. Access detailed analytics to ensure your application runs smoothly:

  • View database performance metrics.
  • Monitor API request rates and latencies.
