Lastly, Supabase takes care of the infrastructure and scaling aspects, allowing developers to focus on building the application logic without worrying about the backend setup.

### Setting Up Supabase

To get started with Supabase development, you need to create a Supabase project and configure the necessary credentials. Follow the steps below to set up Supabase:

#### Creating a Supabase project

1. Visit the Supabase website (https:&#x2F;&#x2F;supabase.io) and sign up for an account.
2. Once signed in, create a new project and provide a name and description for it.
3. After creating the project, you will be redirected to the project dashboard where you can access the project&#x27;s API keys and other configurations.

#### Configuring Supabase credentials

To connect to Supabase from your application, you need to configure the necessary credentials. Supabase provides two sets of credentials: the &#96;SUPABASE_URL&#96; and the &#96;SUPABASE_KEY&#96;. The &#96;SUPABASE_URL&#96; is the URL of your Supabase project and the &#96;SUPABASE_KEY&#96; is a secret key that grants access to your project&#x27;s data.

To configure the Supabase credentials, follow these steps:

1. In your project dashboard, navigate to the &quot;Settings&quot; tab.
2. Under the &quot;API&quot; section, you will find the &#96;SUPABASE_URL&#96;. Copy this URL and store it securely in your application&#x27;s environment variables.
3. In the same section, you will also find the &#96;SUPABASE_KEY&#96;. Copy this key and store it securely in your application&#x27;s environment variables as well.

#### Connecting to Supabase from your application

To connect to Supabase from your application, you will need to install the Supabase JavaScript library and initialize it with your project&#x27;s credentials. Follow these steps to establish a connection:

1. Install the Supabase JavaScript library using a package manager like npm or yarn:

&#96;&#96;&#96;shell
npm install @supabase&#x2F;supabase-js
&#96;&#96;&#96;

2. Import the Supabase library in your application:

&#96;&#96;&#96;javascript
import { createClient } from &#x27;@supabase&#x2F;supabase-js&#x27;;
&#96;&#96;&#96;

3. Initialize the Supabase client with your project&#x27;s credentials:

&#96;&#96;&#96;javascript
const supabase = createClient(SUPABASE_URL, SUPABASE_KEY);
&#96;&#96;&#96;

Replace &#96;SUPABASE_URL&#96; and &#96;SUPABASE_KEY&#96; with the actual values from your project&#x27;s credentials.

## Database Management

### Creating tables and schemas

Supabase allows you to create tables and define schemas using SQL queries. To create a table, you can use the &#96;supabase.from()&#96; method to access the &#96;table&#96; object. Then, you can use the &#96;create()&#96; method to define the schema and create the table.

&#96;&#96;&#96;javascript
const { data, error } = await supabase.from(&#x27;table&#x27;).create([
  { name: &#x27;id&#x27;, type: &#x27;uuid&#x27;, primary: true },
  { name: &#x27;name&#x27;, type: &#x27;text&#x27; },
  { name: &#x27;age&#x27;, type: &#x27;integer&#x27; },
]);
&#96;&#96;&#96;

In the example above, we create a table called &quot;table&quot; with three columns: &quot;id&quot; of type &quot;uuid&quot; as the primary key, &quot;name&quot; of type &quot;text&quot;, and &quot;age&quot; of type &quot;integer&quot;.

### Defining relationships between tables

Supabase supports defining relationships between tables using foreign keys. To create a foreign key relationship, you can use the &#96;references()&#96; method to specify the referenced table and column.

&#96;&#96;&#96;javascript
const { data, error } = await supabase.from(&#x27;table1&#x27;).alterTable((table) =&gt; {
  table.foreign(&#x27;column_id&#x27;).references(&#x27;table2.column_id&#x27;);
});
&#96;&#96;&#96;

In the example above, we create a foreign key relationship between &quot;table1&quot; and &quot;table2&quot; using the &quot;column_id&quot; column.

### Performing CRUD operations on the database

Supabase provides a set of methods to perform CRUD (Create, Read, Update, Delete) operations on the database. Here are some examples:

- Read data from a table:

&#96;&#96;&#96;javascript
const { data, error } = await supabase.from(&#x27;table&#x27;).select(&#x27;*&#x27;);
&#96;&#96;&#96;

- Insert data into a table:

&#96;&#96;&#96;javascript
const { data, error } = await supabase.from(&#x27;table&#x27;).insert([
  { name: &#x27;John&#x27;, age: 25 },
  { name: &#x27;Jane&#x27;, age: 30 },
]);
&#96;&#96;&#96;

- Update data in a table:

&#96;&#96;&#96;javascript
const { data, error } = await supabase
  .from(&#x27;table&#x27;)
  .update({ age: 35 })
  .match({ name: &#x27;John&#x27; });
&#96;&#96;&#96;

- Delete data from a table:

&#96;&#96;&#96;javascript
const { data, error } = await supabase
  .from(&#x27;table&#x27;)
  .delete()
  .match({ name: &#x27;John&#x27; });
&#96;&#96;&#96;

Replace &quot;table&quot; with the actual name of the table you want to perform the operation on.

## Authentication and Authorization

### Setting up user authentication

Supabase provides an easy-to-use authentication system that allows you to authenticate users in your application. To set up user authentication, follow these steps:

1. Enable the authentication provider(s) of your choice in the Supabase project dashboard.
2. Install the necessary authentication library in your application. For example, if you are using React, you can install the &#96;@supabase&#x2F;supabase-js&#96; library:

&#96;&#96;&#96;shell
npm install @supabase&#x2F;supabase-js
&#96;&#96;&#96;

3. Import the authentication library and initialize it with your Supabase credentials:

&#96;&#96;&#96;javascript
import { createClient } from &#x27;@supabase&#x2F;supabase-js&#x27;;

const supabase = createClient(SUPABASE_URL, SUPABASE_KEY);
&#96;&#96;&#96;

4. Use the authentication methods provided by Supabase to handle user registration, login, and logout:

&#96;&#96;&#96;javascript
&#x2F;&#x2F; User registration
const { user, error } = await supabase.auth.signUp({ email, password });

&#x2F;&#x2F; User login
const { user, error } = await supabase.auth.signIn({ email, password });

&#x2F;&#x2F; User logout
await supabase.auth.signOut();
&#96;&#96;&#96;

### Implementing role-based access control

Supabase allows you to implement role-based access control (RBAC) to restrict access to certain resources based on user roles. To implement RBAC, follow these steps:

1. Define the roles and their permissions in the Supabase project dashboard.
2. Assign roles to users during registration or through the Supabase API.
3. Use the &#96;hasRole()&#96; method to check if a user has a specific role:

&#96;&#96;&#96;javascript
const hasAdminRole = supabase.auth.user()?.hasRole(&#x27;admin&#x27;);
&#96;&#96;&#96;

4. Use the &#96;hasPermission()&#96; method to check if a user has a specific permission:

&#96;&#96;&#96;javascript
const canCreate = supabase.auth.user()?.hasPermission(&#x27;create&#x27;);
&#96;&#96;&#96;

Replace &quot;admin&quot; and &quot;create&quot; with the actual role and permission you want to check.

## Real-time Updates

### Listening to database changes in real-time

Supabase allows you to listen to database changes in real-time using the &#96;supabase.from().on()&#96; method. This method enables you to subscribe to changes happening in a specific table or query. Here&#x27;s an example:

&#96;&#96;&#96;javascript
const subscription = supabase
  .from(&#x27;table&#x27;)
  .on(&#x27;*&#x27;, (payload) =&gt; {
    console.log(&#x27;Change:&#x27;, payload);
  })
  .subscribe();
&#96;&#96;&#96;

In the example above, we subscribe to all changes happening in the &quot;table&quot; and log the payload to the console.

### Implementing real-time notifications

Supabase provides a built-in real-time notification system that allows you to send notifications to connected clients. To implement real-time notifications, follow these steps:

1. Create a trigger in the Supabase project dashboard that sends a notification whenever a specific event occurs.
2. Subscribe to the notifications using the &#96;supabase.notifications.on()&#96; method:

&#96;&#96;&#96;javascript
const subscription = supabase.notifications.on(&#x27;new_notification&#x27;, (payload) =&gt; {
  console.log(&#x27;Notification:&#x27;, payload);
});
&#96;&#96;&#96;

In the example above, we subscribe to the &quot;new_notification&quot; event and log the payload to the console.

## File Storage

### Uploading and managing files in Supabase

Supabase provides a file storage system that allows you to upload and manage files directly from your application. To upload a file, use the &#96;supabase.storage.from().upload()&#96; method:

&#96;&#96;&#96;javascript
const { data, error } = await supabase.storage
  .from(&#x27;bucket&#x27;)
  .upload(&#x27;file.jpg&#x27;, file);
&#96;&#96;&#96;

In the example above, we upload a file named &quot;file.jpg&quot; to the &quot;bucket&quot; storage bucket.

To retrieve a file, use the &#96;supabase.storage.from().download()&#96; method:

&#96;&#96;&#96;javascript
const { data, error } = await supabase.storage
  .from(&#x27;bucket&#x27;)
  .download(&#x27;file.jpg&#x27;);
&#96;&#96;&#96;

In the example above, we download the file named &quot;file.jpg&quot; from the &quot;bucket&quot; storage bucket.

### Integrating file storage with your application

To integrate file storage with your application, you can use the URLs provided by Supabase to display or download the files. For example, to display an image, you can use the following code:

&#96;&#96;&#96;html
&lt;img src=&quot;https:&#x2F;&#x2F;&lt;supabase-url&gt;&#x2F;storage&#x2F;v1&#x2F;object&#x2F;public&#x2F;&lt;bucket&gt;&#x2F;file.jpg&quot; alt=&quot;File&quot; &#x2F;&gt;
&#96;&#96;&#96;

Replace &#96;&lt;supabase-url&gt;&#96; with the URL of your Supabase project, &#96;&lt;bucket&gt;&#96; with the name of the storage bucket, and &#96;file.jpg&#96; with the actual file name.
