## Comparison

Now that we have explored the features and advantages of Supabase and Firebase individually, let's compare them in different areas to help you make an informed decision.

### Data Storage

Both Supabase and Firebase offer data storage capabilities, but they differ in their approach. Supabase utilizes PostgreSQL, a powerful and reliable relational database, while Firebase offers a NoSQL real-time database.

#### Supabase Data Storage Example

To store data in Supabase, you can use the `supabase-js` library, which provides a simple and intuitive API to interact with the database. Here's an example of how to insert data into a table using Supabase:

```javascript
import { createClient } from '@supabase/supabase-js';

const supabase = createClient('your-supabase-url', 'your-supabase-key');

async function insertData() {
  const { data, error } = await supabase.from('users').insert([
    { name: 'John', email: 'john@example.com' },
    { name: 'Jane', email: 'jane@example.com' },
  ]);

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

insertData();
```

In the example above, we create a Supabase client using the provided URL and API key. We then use the `from` method to specify the table we want to insert data into, and the `insert` method to insert an array of objects representing the data.

#### Firebase Data Storage Example

To store data in Firebase, you can use the Firebase Realtime Database API, which provides a NoSQL JSON data model. Here's an example of how to insert data into a Firebase database:

```javascript
import firebase from 'firebase/app';
import 'firebase/database';

const firebaseConfig = {
  // Your Firebase configuration
};

firebase.initializeApp(firebaseConfig);

async function insertData() {
  const database = firebase.database();

  const usersRef = database.ref('users');
  const newUsersRef = usersRef.push();

  newUsersRef.set({
    name: 'John',
    email: 'john@example.com',
  }, (error) => {
    if (error) {
      console.error('Error inserting data:', error);
    } else {
      console.log('Data inserted successfully');
    }
  });
}

insertData();
```

In the example above, we initialize the Firebase app with the provided configuration. We then get a reference to the `users` collection in the database and use the `push` method to generate a new unique key for the user. Finally, we use the `set` method to insert the data into the database.

### Authentication

Authentication is a crucial component of most applications, and both Supabase and Firebase offer easy-to-use authentication services.

#### Supabase Authentication Example

Supabase provides various authentication providers, including email/password authentication and social logins. Here's an example of how to authenticate a user using Supabase:

```javascript
import { createClient } from '@supabase/supabase-js';

const supabase = createClient('your-supabase-url', 'your-supabase-key');

async function authenticateUser() {
  const { user, session, error } = await supabase.auth.signIn({
    email: 'john@example.com',
    password: 'password123',
  });

  if (error) {
    console.error('Error authenticating user:', error);
  } else {
    console.log('User authenticated successfully:', user, session);
  }
}

authenticateUser();
```

In the example above, we create a Supabase client using the provided URL and API key. We then use the `signIn` method of the `auth` object to authenticate a user using their email and password.

#### Firebase Authentication Example

Firebase offers a wide range of authentication providers, including email/password authentication, social logins, and third-party identity providers. Here's an example of how to authenticate a user using Firebase:

```javascript
import firebase from 'firebase/app';
import 'firebase/auth';

const firebaseConfig = {
  // Your Firebase configuration
};

firebase.initializeApp(firebaseConfig);

async function authenticateUser() {
  const auth = firebase.auth();

  try {
    const userCredential = await auth.signInWithEmailAndPassword('john@example.com', 'password123');
    console.log('User authenticated successfully:', userCredential.user);
  } catch (error) {
    console.error('Error authenticating user:', error);
  }
}

authenticateUser();
```

In the example above, we initialize the Firebase app with the provided configuration. We then get an instance of the `auth` object and use the `signInWithEmailAndPassword` method to authenticate a user using their email and password.

### Real-time Database

Real-time database capabilities are essential for applications that require instant updates. Both Supabase and Firebase provide real-time capabilities, but they differ in their approach.

#### Supabase Real-time Database Example

Supabase utilizes websockets to provide real-time updates to clients. Here's an example of how to listen for real-time updates in Supabase:

```javascript
import { createClient } from '@supabase/supabase-js';

const supabase = createClient('your-supabase-url', 'your-supabase-key');

supabase
  .from('users')
  .on('INSERT', (payload) => {
    console.log('New user inserted:', payload.new);
  })
  .subscribe();
```

In the example above, we create a Supabase client using the provided URL and API key. We then use the `from` method to specify the table we want to listen for updates on. We can then use the `on` method to specify the type of event we want to listen for, in this case, `INSERT`. Finally, we call the `subscribe` method to start listening for real-time updates.

#### Firebase Real-time Database Example

Firebase provides a real-time NoSQL database that automatically syncs data across multiple clients. Here's an example of how to listen for real-time updates in Firebase:

```javascript
import firebase from 'firebase/app';
import 'firebase/database';

const firebaseConfig = {
  // Your Firebase configuration
};

firebase.initializeApp(firebaseConfig);

const database = firebase.database();

database.ref('users').on('child_added', (snapshot) => {
  console.log('New user added:', snapshot.val());
});
```

In the example above, we initialize the Firebase app with the provided configuration. We then get a reference to the `users` collection in the database and use the `on` method to listen for the `child_added` event. Whenever a new child is added to the `users` collection, the callback function will be triggered with a snapshot of the new data.

### Serverless Functions

Serverless functions allow developers to run code in the cloud without managing servers. Both Supabase and Firebase support serverless functions.

#### Supabase Serverless Functions Example

Supabase provides an easy way to create serverless functions using the `supabase` CLI. Here's an example of a Supabase serverless function that returns a random number:

```javascript
// random-number.js
exports.handler = async (event, context) => {
  const randomNumber = Math.random();

  return {
    statusCode: 200,
    body: JSON.stringify({ randomNumber }),
  };
};
```

To deploy the serverless function, navigate to the directory where the function is located and run the following command:

```
supabase functions deploy random-number
```

Once deployed, the function will have a URL that can be used to invoke it.

#### Firebase Serverless Functions Example

Firebase allows developers to write serverless functions using Node.js. Here's an example of a Firebase serverless function that returns a random number:

```javascript
// random-number.js
const functions = require('firebase-functions');

exports.randomNumber = functions.https.onRequest((request, response) => {
  const randomNumber = Math.random();

  response.json({ randomNumber });
});
```

To deploy the serverless function, navigate to the directory where the function is located and run the following command:

```
firebase deploy --only functions
```

Once deployed, the function will have a URL that can be used to invoke it.

### Pricing

Pricing is an important consideration when choosing a BaaS platform. Both Supabase and Firebase offer a range of pricing plans to suit different needs.
