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.

10 Essential Tips for Supabase Development

Angular

In this tutorial, we will explore how to deploy an Angular application to a Kubernetes cluster. We will start by setting up the Kubernetes cluster, installing and configuring it. Then, we will build the Angular application and containerize it using Docker. Finally, we will deploy the Angular application to the Kubernetes cluster, update and roll back the application, and monitor and troubleshoot any issues that may arise.

![deploy angular kubernetes cluster](https://dopebase.com/media/cover19.jpg)
## Introduction

### What is Angular?

Angular is a popular JavaScript framework used for building dynamic web applications. It provides a structured and scalable approach to web development, allowing developers to easily build and maintain complex applications. Angular follows the component-based architecture, where the application is divided into reusable components that encapsulate the logic and UI elements.

### What is Kubernetes?

Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It provides a scalable and reliable environment for running applications in production. Kubernetes abstracts away the underlying infrastructure, allowing developers to focus on building and deploying their applications.

### Why deploy Angular to a Kubernetes cluster?

Deploying an Angular application to a Kubernetes cluster offers several benefits. Firstly, Kubernetes provides a highly scalable and reliable environment for running the application in production. It automatically scales the application based on the demand, ensuring high availability and performance. Secondly, Kubernetes simplifies the deployment process by abstracting away the infrastructure details. It provides a declarative approach to deployment, allowing developers to define the desired state of the application and Kubernetes takes care of the rest. Lastly, deploying Angular to Kubernetes enables easy updates and rollbacks of the application, making it easier to iterate and release new features.

## Setting up the Kubernetes Cluster

### Installing Kubernetes

Before we can deploy our Angular application to a Kubernetes cluster, we need to set up the cluster. The first step is to install Kubernetes on our local machine or a remote server. There are several ways to install Kubernetes, but in this tutorial, we will use Minikube, which is a tool that allows us to run a single-node Kubernetes cluster on our local machine.

To install Minikube, follow the instructions specific to your operating system provided in the official Minikube documentation (https://minikube.sigs.k8s.io/docs/start/). Once installed, start the Minikube cluster using the following command:

```shell
minikube start
```

This command will start a single-node Kubernetes cluster locally.

### Configuring the Cluster

After successfully installing Minikube and starting the cluster, we need to configure our Kubernetes cluster to deploy our Angular application. The first step is to create a Deployment, which defines the desired state of our application. The Deployment specifies the container image, the number of replicas, and other configurations.

Create a file named `deployment.yaml` and add the following content:

```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: angular-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: angular-app
  template:
    metadata:
      labels:
        app: angular-app
    spec:
      containers:
        - name: angular-app
          image: <docker-registry>/angular-app:latest
          ports:
            - containerPort: 80
```

In the above YAML file, we define a Deployment with the name "angular-app" and specify that we want to run 3 replicas of our application. The "selector" field selects the Pods that match the specified labels, and the "template" field defines the Pod template with the container configuration.

Replace `<docker-registry>` with the address of your Docker registry where the Docker image of the Angular application will be pushed.

Next, create a Service to expose our application to the outside world. Create a file named `service.yaml` and add the following content:

```yaml
apiVersion: v1
kind: Service
metadata:
  name: angular-app
spec:
  selector:
    app: angular-app
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80
  type: LoadBalancer
```

In the above YAML file, we define a Service named "angular-app" that selects the Pods with the label "app: angular-app". The Service exposes the Pods on port 80 and uses the LoadBalancer type to automatically create a load balancer that distributes the traffic to the Pods.

## Building the Angular Application

Before we can deploy our Angular application to the Kubernetes cluster, we need to build it. In this section, we will create a new Angular project, configure it for deployment, and build the production-ready Angular application.

### Creating a new Angular project

To create a new Angular project, make sure you have the Angular CLI installed. If you don't have it installed, you can install it globally by running the following command:

```shell
npm install -g @angular/cli
```

Once the Angular CLI is installed, create a new Angular project by running the following command:

```shell
ng new angular-app
```

This command will create a new directory named "angular-app" with the basic structure of an Angular project.

### Configuring the project for deployment

To configure the Angular project for deployment, we need to make a few changes. Open the `angular.json` file in the root directory of the project and locate the "projects" section. Inside the "projects" section, find the configuration for the "architect.build" target and add the following properties:

```json
"outputPath": "dist/angular-app",
"baseHref": "/",
```

The "outputPath" property specifies the directory where the production-ready Angular application will be built. The "baseHref" property sets the base URL for the application, which is necessary for proper routing.

### Building the production-ready Angular application

To build the production-ready Angular application, navigate to the root directory of the project and run the following command:

```shell
ng build --prod
```

This command will start the build process and generate the production-ready files in the specified output directory.

## Containerizing the Angular Application

To deploy our Angular application to a Kubernetes cluster, we need to containerize it using Docker. In this section, we will create a Dockerfile, build the Docker image, and push it to a Docker registry.

### Creating a Dockerfile

Create a file named `Dockerfile` in the root directory of the Angular project and add the following content:

```Dockerfile
# Use the official Nginx image as the base image
FROM nginx:latest

# Copy the built Angular application to the Nginx default public directory
COPY dist/angular-app /usr/share/nginx/html

# Expose port 80
EXPOSE 80

# Start Nginx when the Docker container starts
CMD ["nginx", "-g", "daemon off;"]
```

In the above Dockerfile, we use the official Nginx image as the base image. We copy the built Angular application from the specified output directory to the Nginx default public directory. We expose port 80 to allow external access to the application. Finally, we start the Nginx server when the Docker container starts.

### Building the Docker image

To build the Docker image, navigate to the root directory of the Angular project and run the following command:

```shell
docker build -t <docker-registry>/angular-app:latest .
```

Replace `<docker-registry>` with the address of your Docker registry where you want to push the Docker image.

This command will build the Docker image using the Dockerfile in the current directory and tag it with the specified registry and image name.

### Pushing the Docker image to a registry

To push the Docker image to a registry, run the following command:

```shell
docker push <docker-registry>/angular-app:latest
```

Replace `<docker-registry>` with the address of your Docker registry.

This command will push the Docker image to the specified registry.

## Deploying the Angular Application to Kubernetes

Now that we have set up the Kubernetes cluster, built the Angular application, and containerized it, we are ready to deploy the Angular application to the Kubernetes cluster.

### Creating Kubernetes manifests

To deploy the Angular application to the Kubernetes cluster, we need to create Kubernetes manifests. Create a file named `deployment.yaml` and add the following content:

```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: angular-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: angular-app
  template:
    metadata:
      labels:
        app: angular-app
    spec:
      containers:
        - name: angular-app
          image: <docker-registry>/angular-app:latest
          ports:
            - containerPort: 80
```

In the above YAML file, we define a Deployment with the name "angular-app" and specify that we want to run 3 replicas of our application. The "selector" field selects the Pods that match the specified labels, and the "template" field defines the Pod template with the container configuration.

Replace `<docker-registry>` with the address of your Docker registry where the Docker image of the Angular application is pushed.

### Deploying the application to the cluster

To deploy the Angular application to the Kubernetes cluster, run the following command:

```shell
kubectl apply -f deployment.yaml
```

This command applies the Kubernetes manifest and creates the Deployment in the cluster.

### Scaling the application

To scale the Angular application, we can update the number of replicas in the Deployment. Open the `deployment.yaml` file and modify the value of the "replicas" field. For example, to scale the application to 5 replicas, change the line to:

```yaml
replicas: 5
```

Save the file and apply the changes to the cluster by running the following command:

```shell
kubectl apply -f deployment.yaml
```

This command updates the Deployment and scales the application to the desired number of replicas.

## Updating and Rolling Back the Application

Deploying an Angular application to a Kubernetes cluster enables easy updates and rollbacks of the application. In this section, we will explore how to update the Angular application and roll back to a previous version if needed.

### Updating the Angular application

To update the Angular application, make the necessary changes to the source code and rebuild the application using the steps mentioned in the "Building the Angular Application" section. Once the new version of the application is built, create a new Docker image and push it to the Docker registry.

After pushing the new Docker image, update the Deployment in the Kubernetes cluster to use the latest image. Open the `deployment.yaml` file and modify the "image" field to point to the new Docker image. For example:

```yaml
image: <docker-registry>/angular-app:new-version
```

Save the file and apply the changes to the cluster by running the following command:

```shell
kubectl apply -f deployment.yaml
```

This command updates the Deployment and deploys the new version of the Angular application to the cluster.

### Rolling back to a previous version

If the new version of the Angular application introduces issues or errors, you can roll back to a previous version. To roll back, simply update the Deployment in the Kubernetes cluster to use the previous version of the Docker image. Open the `deployment.yaml` file and modify the "image" field to point to the previous Docker image. For example:

```yaml
image: <docker-registry>/angular-app:previous-version
```

Save the file and apply the changes to the cluster by running the following command:

```shell
kubectl apply -f deployment.yaml
```

This command updates the Deployment and rolls back the Angular application to the previous version.

## Monitoring and Troubleshooting

To ensure the smooth operation of the deployed Angular application on the Kubernetes cluster, it is essential to monitor and troubleshoot any issues that may arise. In this section, we will explore how to monitor the application and troubleshoot common issues.

### Monitoring the application

Kubernetes provides various monitoring tools and frameworks to monitor the deployed applications. One popular tool is Prometheus, which is an open-source monitoring and alerting toolkit. To set up monitoring for the Angular application, follow the instructions provided in the Prometheus documentation (https://prometheus.io/docs/introduction/overview/).

Prometheus collects metrics from the deployed application and provides a graphical interface to visualize and analyze the data. By monitoring the application, you can identify any performance bottlenecks or issues and take appropriate actions.

### Troubleshooting common issues

When deploying an Angular application to a Kubernetes cluster, you may encounter common issues such as pod crashes, resource constraints, or networking problems. To troubleshoot these issues, Kubernetes provides various troubleshooting tools and techniques.

One useful tool is kubectl, the command-line interface for interacting with the Kubernetes cluster. You can use kubectl to check the status of the Pods, view the logs of the containers, and execute commands inside the containers.

To view the logs of a specific Pod, use the following command:

```shell
kubectl logs <pod-name>
```

Replace `<pod-name>` with the name of the Pod you want to view the logs for. This command will display the logs of the specified Pod, helping you identify any errors or issues.

After creating a project, you will be redirected to the project dashboard. Here, you can find your project URL, API URL, and API key. These credentials are required to connect to your Supabase database and make API requests. Make sure to securely store these credentials as they are sensitive.

To configure Supabase in your application, you need to install the Supabase client library. You can install it via npm by running the following command:

```bash
npm install @supabase/supabase-js
```

Once installed, you can initialize the Supabase client by providing your project URL and API key:

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

const supabaseUrl = 'https://your-project-url.supabase.co';
const supabaseKey = 'your-api-key';
const supabase = createClient(supabaseUrl, supabaseKey);
```

With the Supabase client initialized, you are now ready to manage your database.

## Database Management

### Creating Tables

To create a table in Supabase, you can use the `supabase.createTable()` method. This method takes two arguments: the table name and an object representing the table schema. The schema defines the columns and their data types for the table.

```javascript
const { data, error } = await supabase.createTable('users', {
  id: {
    type: 'integer',
    primaryKey: true,
    notNull: true,
  },
  name: {
    type: 'text',
    notNull: true,
  },
  email: {
    type: 'text',
    notNull: true,
    unique: true,
  },
  createdAt: {
    type: 'timestamp',
    default: 'now()',
  },
});
```

In the above example, we create a table named "users" with four columns: "id", "name", "email", and "createdAt". The "id" column is defined as an integer primary key, while the "name" and "email" columns are defined as non-null text fields. The "createdAt" column is a timestamp with a default value of the current timestamp.

### Defining Relationships

Supabase supports defining relationships between tables using foreign keys. To define a foreign key relationship, you can use the `supabase.createTable()` method and the `references` property in the column definition.

```javascript
const { data, error } = await supabase.createTable('orders', {
  id: {
    type: 'integer',
    primaryKey: true,
    notNull: true,
  },
  userId: {
    type: 'integer',
    references: 'users',
  },
  totalAmount: {
    type: 'numeric',
    notNull: true,
  },
});
```

In the above example, we create a table named "orders" with three columns: "id", "userId", and "totalAmount". The "userId" column is defined as an integer and references the "users" table. This establishes a foreign key relationship between the "orders" and "users" tables.

### Performing CRUD Operations

Supabase provides a set of methods for performing CRUD (Create, Read, Update, Delete) operations on your database. Here are some examples:

#### Create

To insert a new row into a table, you can use the `supabase.insert()` method.

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

In the above example, we insert two new rows into the "users" table.

#### Read

To fetch data from a table, you can use the `supabase.from()` method.

```javascript
const { data, error } = await supabase.from('users').select('*');
```

In the above example, we fetch all columns (`*`) from the "users" table.

#### Update

To update existing rows in a table, you can use the `supabase.update()` method.

```javascript
const { data, error } = await supabase
  .from('users')
  .update({ name: 'John Smith' })
  .eq('id', 1);
```

In the above example, we update the "name" column of the row with the ID of 1 in the "users" table.

#### Delete

To delete rows from a table, you can use the `supabase.delete()` method.

```javascript
const { data, error } = await supabase.from('users').delete().eq('id', 1);
```

In the above example, we delete the row with the ID of 1 from the "users" table.

## Authentication

### Setting Up Authentication

Supabase provides built-in authentication functionality to handle user registration, login, and session management. To enable authentication in your project, you need to configure the authentication providers and initialize the authentication client.

#### Configuring Providers

To configure authentication providers, navigate to the "Authentication" section in your project dashboard. Here, you can enable and configure various providers, such as email/password, Google, GitHub, and more. Follow the on-screen instructions for each provider to set up the required credentials.

#### Initializing the Authentication Client

To initialize the authentication client, you can use the `supabase.auth` object.

```javascript
const auth = supabase.auth;
```

With the authentication client initialized, you can now perform various authentication actions.

### User Registration

To allow users to register in your application, you can use the `auth.signUp()` method.

```javascript
const { user, error } = await auth.signUp({
  email: 'john@example.com',
  password: 'password123',
});
```

In the above example, we register a new user with the email "john@example.com" and the password "password123".

### User Login

To authenticate users in your application, you can use the `auth.signIn()` method.

```javascript
const { user, error } = await auth.signIn({
  email: 'john@example.com',
  password: 'password123',
});
```

In the above example, we authenticate the user with the email "john@example.com" and the password "password123".

## Real-time Subscriptions

### Enabling Real-time Subscriptions

Supabase provides real-time subscription functionality, allowing you to listen for changes in your database and receive updates in real-time. To enable real-time subscriptions, you need to configure the triggers and initialize the real-time client.

#### Configuring Triggers

To configure triggers, navigate to the "Database" section in your project dashboard and select the table for which you want to enable real-time subscriptions. Click on the "Triggers" tab and create a new trigger. You can define the trigger condition and the action to be performed when the condition is met.

#### Initializing the Real-time Client

To initialize the real-time client, you can use the `supabase.realtime` object.

```javascript
const realtime = supabase.realtime;
```

With the real-time client initialized, you can now listen for changes and handle real-time updates.

### Listening for Changes

To listen for changes in a table, you can use the `realtime.from()` method.

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

In the above example, we listen for new rows (`INSERT`) in the "users" table. Whenever a new row is inserted, the callback function is invoked, and the new row data is logged to the console.

### Handling Real-time Updates

To handle real-time updates, you can use the appropriate callback functions based on the type of change (`INSERT`, `UPDATE`, `DELETE`).

```javascript
const unsubscribe = realtime
  .from('users')
  .on('*', (payload) => {
    console.log('Change occurred:', payload);
  })
  .subscribe();
```

In the above example, we listen for any change (`*`) in the "users" table. Whenever a change occurs, the callback function is invoked, and the change payload is logged to the console.

## API Endpoints

### Creating Custom API Endpoints

Supabase allows you to create custom API endpoints to perform server-side logic and interact with your database. To create a custom API endpoint, you can use the Supabase CLI or the Supabase Dashboard.

#### Supabase CLI

To create a custom API endpoint using the Supabase CLI, navigate to your project directory and run the following command:

```bash
supabase generate api my-endpoint
```

This will generate a new API endpoint in the `api` directory of your project. You can then implement your server-side logic in the generated files.

#### Supabase Dashboard

To create a custom API endpoint using the Supabase Dashboard, navigate to the "API" section in your project dashboard. Click on the "New Endpoint" button and enter a name for your endpoint. You can then define the route, HTTP methods, and serverless function code for your endpoint.

### Securing API Endpoints

Supabase allows you to secure your API endpoints using various authentication mechanisms, such as API keys, JWT tokens, or custom authentication logic. To secure an API endpoint, you can use the `supabase.auth.api()` method.

```javascript
const { data, error } = await supabase.auth.api('my-endpoint').get('/path');
```

In the above example, we secure the API endpoint named "my-endpoint" and make a GET request to the "/path" route.

### Testing API Endpoints

To test your API endpoints, you can use tools like cURL or Postman. Make sure to include the appropriate authentication headers or tokens when making API requests to secured endpoints.

```bash
curl -H 'Authorization: Bearer <api-key>' https://api.supabase.co/my-endpoint/path
```

In the above example, we make a cURL request to the "/path" route of the "my-endpoint" API endpoint, including the API key in the Authorization header.

Netlify integrates seamlessly with popular version control systems like Git, making it easy to automate the deployment process.

## Setting up Angular App

### Creating a new Angular project

To get started, make sure you have Node.js installed on your machine. Open a terminal and run the following command to install the Angular CLI (Command Line Interface):

```bash
npm install -g @angular/cli
```

Once the installation is complete, you can create a new Angular project by running the following command:

```bash
ng new my-app
```

This will create a new directory called "my-app" with the basic structure and files of an Angular project.

### Configuring Angular app for deployment

Before deploying your Angular app, you need to configure it for production. Open the "angular.json" file in the root of your project directory, and locate the "build" configuration section. Make sure the "outputPath" property is set to "dist":

```json
"build": {
  "builder": "@angular-devkit/build-angular:browser",
  "options": {
    "outputPath": "dist/my-app",
    ...
  },
  ...
}
```

This will ensure that the built files are stored in the "dist/my-app" directory, which is the default directory for Angular's production build.

## Deploying to Netlify

### Creating a Netlify account

To deploy your Angular app on Netlify, you first need to create a Netlify account. Go to the Netlify website (https://www.netlify.com/) and sign up for a free account. Once you have signed up, you will be redirected to the Netlify dashboard.

### Connecting Netlify to your Git repository

In the Netlify dashboard, click on the "New site from Git" button. Select your preferred Git provider (e.g., GitHub, GitLab, Bitbucket) and follow the instructions to connect your repository to Netlify. Netlify will automatically detect your Angular project and configure the basic deployment settings.

### Configuring build settings

Before deploying your Angular app, you can configure the build settings in Netlify. In the Netlify dashboard, click on your site's name and navigate to the "Build & Deploy" settings. Here, you can set the build command to "ng build --prod" and the publish directory to "dist/my-app".

### Caching and CDN

Netlify uses a global CDN to cache and serve your Angular app's static assets. This improves the performance of your app by reducing the latency of content delivery. Netlify automatically sets cache headers for your files, ensuring that they are cached by the CDN for optimal performance.

### Lazy loading

Lazy loading is a technique that allows you to load Angular modules and components on-demand, instead of loading them all upfront. This can significantly improve the initial load time of your app, especially if you have a large codebase. To enable lazy loading in your Angular app, use the Angular Router's lazy loading feature. This allows you to split your app into multiple modules and load them only when needed.

### Code splitting

Code splitting is another optimization technique that allows you to split your app's code into smaller chunks, which can be loaded on-demand. This reduces the initial load time of your app by only loading the required code for the current page. Angular CLI provides built-in support for code splitting using the "--aot" (Ahead-of-Time compilation) flag. When building your Angular app for production, run the following command:

```bash
ng build --prod --aot
```

This will generate separate bundles for each lazy-loaded module and optimize the size of your app's code.

## Conclusion

In this tutorial, we have learned how to host your Angular app on Netlify with ease. We started by setting up an Angular project, configuring it for deployment, and deploying it to Netlify. We also covered setting up a custom domain, enabling SSL for your app, automating deployments with Netlify using webhooks, and optimizing performance using caching and CDN, lazy loading, and code splitting. With these techniques, you can ensure that your Angular app is hosted securely and performs optimally for your users.

3. Apply the deployment configuration to your Kubernetes cluster using the `kubectl apply` command.
4. Monitor the deployment status using the Kubernetes dashboard or command-line tools.

## Monitoring and Logging in Angular Applications

Monitoring and logging are essential for maintaining the health and performance of Angular applications. Let's explore how we can implement logging, monitor performance, and track errors in Angular applications.

### Implementing Logging

Logging allows you to capture and store relevant information about the behavior of your Angular application. There are several logging libraries available for Angular, such as ngx-logger and angular2-logger.

#### Setting Up ngx-logger

To set up ngx-logger for your Angular project, follow these steps:

1. Install ngx-logger by running the following command within your project directory:

```bash
npm install ngx-logger --save
```

2. Configure the logger in your Angular application by importing the `LoggerModule` and adding it to your module's imports array.
3. Inject the `Logger` service into your components or services and use it to log messages at various levels (e.g., `info`, `debug`, `error`).

### Monitoring Performance

Monitoring the performance of your Angular application helps you identify bottlenecks and optimize its speed and responsiveness. There are various tools and techniques available for monitoring Angular application performance, such as using the Performance tab in Chrome DevTools or integrating with third-party monitoring services like New Relic or Datadog.

## Introduction

### What is Docker?

Docker is an open-source platform that enables developers to automate the deployment and scaling of applications using containerization. Containers are lightweight, isolated environments that package an application and its dependencies, allowing it to run consistently across different operating systems and environments. Docker provides a consistent and reproducible way to package and deploy applications, making it easier to develop, test, and deploy software.

### What is Angular?

Angular is a popular JavaScript framework for building web applications. It provides a comprehensive set of tools and features for building scalable and maintainable applications. Angular follows the component-based architecture, making it easy to reuse and modularize code. It also provides a powerful templating system and two-way data binding, making it easier to build dynamic and interactive user interfaces.

### Benefits of Containerization

Containerization offers several benefits for Angular applications:

#### Isolation and Portability

By packaging an application and its dependencies into a container, you can ensure that the application runs consistently across different environments. This eliminates the "it works on my machine" problem and makes it easier to share and deploy applications.

#### Scalability

Containers can be easily scaled up or down to handle varying levels of traffic. By leveraging container orchestration platforms like Kubernetes, you can automatically scale your application based on demand, ensuring high availability and performance.

#### Efficiency

Containers are lightweight and have minimal overhead compared to traditional virtual machines. They start quickly and consume fewer resources, making them an efficient choice for deploying applications.

## Getting Started with Docker

### Installing Docker

To get started with Docker, you need to install Docker on your development machine. Docker provides installation packages for various operating systems, including Windows, macOS, and Linux. Visit the Docker website (https://www.docker.com/) and follow the installation instructions for your specific operating system.

### Creating a Dockerfile

A Dockerfile is a text file that contains instructions for building a Docker image. It specifies the base image to use, copies application files into the image, installs dependencies, and configures the container. Let's create a Dockerfile for our Angular application:

```Dockerfile
# Use the official Node.js base image
FROM node:10

# Set the working directory in the container
WORKDIR /app

# Copy package.json and package-lock.json to the working directory
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the rest of the application files to the working directory
COPY . .

# Build the Angular app
RUN npm run build --prod

# Expose the default Angular port
EXPOSE 4200

# Start the Angular app when the container starts
CMD ["npm", "start"]
```

Let's go through each line of the Dockerfile:

- `FROM node:10`: This specifies the base image to use for our Docker image. In this case, we are using the official Node.js image with version 10.
- `WORKDIR /app`: This sets the working directory inside the container to `/app`. This is where our application files will be copied.
- `COPY package*.json ./`: This copies the `package.json` and `package-lock.json` files from the host machine to the working directory inside the container.
- `RUN npm install`: This installs the dependencies specified in the `package.json` file inside the container.
- `COPY . .`: This copies the rest of the application files from the host machine to the working directory inside the container.
- `RUN npm run build --prod`: This builds the Angular app inside the container using the `npm run build` command. The `--prod` flag is used to build the app for production.
- `EXPOSE 4200`: This exposes port 4200, which is the default port used by Angular applications.
- `CMD ["npm", "start"]`: This specifies the command to run when the container starts. In this case, we are starting the Angular app using the `npm start` command.

### Building Docker Images

Once you have created the Dockerfile, you can build a Docker image using the `docker build` command. Open a terminal or command prompt, navigate to the directory containing the Dockerfile, and run the following command:

```bash
docker build -t my-angular-app .
```

The `-t` flag specifies the name and tag for the image. In this case, we are naming the image `my-angular-app`. The `.` at the end of the command specifies the build context, which is the directory containing the Dockerfile.

### Running Docker Containers

Once you have built the Docker image, you can run a Docker container using the `docker run` command. Run the following command to start a container from the `my-angular-app` image:

```bash
docker run -p 8080:4200 my-angular-app
```

The `-p` flag specifies the port mapping between the host machine and the container. In this case, we are mapping port 8080 on the host machine to port 4200 inside the container. This allows us to access the Angular app running inside the container at `http://localhost:8080`.

## Containerizing an Angular App

### Setting up an Angular Project

Before we can containerize an Angular app, we need to set up a new Angular project. If you already have an existing Angular project, you can skip this step. Otherwise, open a terminal or command prompt and run the following command to install the Angular CLI globally:

```bash
npm install -g @angular/cli
```

Once the Angular CLI is installed, you can create a new Angular project using the following command:

```bash
ng new my-angular-app
```

This will create a new directory called `my-angular-app` containing the basic structure and files for an Angular application.

### Configuring Docker for Angular

To configure Docker for an Angular app, we need to create a Dockerfile and specify the necessary instructions. Create a new file called `Dockerfile` in the root directory of your Angular project and paste the following content:

```Dockerfile
# Use the official Node.js base image
FROM node:10

# Set the working directory in the container
WORKDIR /app

# Copy package.json and package-lock.json to the working directory
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the rest of the application files to the working directory
COPY . .

# Build the Angular app
RUN npm run build --prod

# Expose the default Angular port
EXPOSE 4200

# Start the Angular app when the container starts
CMD ["npm", "start"]
```

This Dockerfile is similar to the one we created earlier. It specifies the base image, sets the working directory, installs dependencies, copies the application files, builds the Angular app, and starts the app when the container starts.

### Building Docker Image for Angular

To build a Docker image for your Angular app, open a terminal or command prompt, navigate to the root directory of your Angular project (where the Dockerfile is located), and run the following command:

```bash
docker build -t my-angular-app .
```

This command builds a Docker image with the tag `my-angular-app`. The `.` at the end of the command specifies the build context, which is the current directory.

### Running Angular App in a Docker Container

Once you have built the Docker image, you can run a Docker container using the following command:

```bash
docker run -p 8080:4200 my-angular-app
```

This command starts a container from the `my-angular-app` image and maps port 8080 on the host machine to port 4200 inside the container. You can access the Angular app running inside the container at `http://localhost:8080`.

## Best Practices

### Optimizing Docker Images

Optimizing Docker images can help reduce the size and improve the performance of your containers. Here are some best practices for optimizing Docker images for Angular applications:

#### Using Environment Variables

You can use environment variables in your Dockerfile to make it more flexible and configurable. For example, you can pass the base URL of your API server as an environment variable, allowing you to easily switch between different environments without modifying the Dockerfile. Here's an example of how to use environment variables in a Dockerfile:

```Dockerfile
# Use the official Node.js base image
FROM node:10

# Set the working directory in the container
WORKDIR /app

# Copy package.json and package-lock.json to the working directory
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the rest of the application files to the working directory
COPY . .

# Build the Angular app with environment variables
ARG API_BASE_URL
ENV API_BASE_URL=$API_BASE_URL
RUN npm run build --prod
```

In this example, we define an environment variable called `API_BASE_URL` using the `ARG` and `ENV` instructions. The value of the `API_BASE_URL` variable can be passed as a build argument when building the Docker image.

#### Managing Dependencies

To minimize the size of your Docker image, it's important to manage dependencies efficiently. Here are some tips for managing dependencies in Docker images:

- Use the `--production` flag when running `npm install` to exclude development dependencies from the production image.
- Use a multi-stage build to separate the build environment from the runtime environment. This allows you to install and build dependencies in a separate image and copy only the necessary files to the final image.
- Use a package manager like Yarn instead of npm, as Yarn can cache installed dependencies and speed up subsequent builds.

#### Logging and Monitoring

Logging and monitoring are important aspects of running Dockerized applications. Docker provides various logging drivers that allow you to send container logs to different destinations, such as the console, a file, or a log management service. You can configure the logging driver by specifying the `--log-driver` flag when running a container. Additionally, you can use monitoring tools like Prometheus and Grafana to collect and visualize metrics from your Docker containers.

## Deployment and Continuous Integration

### Deploying Dockerized Angular App

Once you have containerized your Angular app, you can deploy it to a production environment. There are several ways to deploy Dockerized applications, depending on your requirements and infrastructure. Here are some common deployment strategies:

- Self-hosted: You can deploy Docker containers on your own infrastructure, either on-premises or in the cloud. This gives you full control over the deployment process but requires managing the underlying infrastructure.
- Cloud providers: Cloud providers like AWS, Google Cloud, and Azure offer container orchestration platforms (e.g., AWS ECS, Google Kubernetes Engine, Azure Kubernetes Service) that simplify the deployment and management of Docker containers.
- Container-as-a-Service (CaaS): CaaS platforms like Docker Enterprise, Rancher, and Red Hat OpenShift provide a complete solution for deploying and managing Docker containers. They offer features like load balancing, scaling, and service discovery out of the box.
- Serverless: Serverless platforms like AWS Lambda and Google Cloud Functions allow you to run code without provisioning or managing servers. You can package your Angular app as a serverless function and deploy it using a serverless platform.

### Automating Builds with CI/CD

Continuous Integration and Continuous Deployment (CI/CD) is a development practice that allows you to automate the build, test, and deployment process of your applications. By integrating Docker into your CI/CD pipeline, you can automate the building and deployment of Docker images. Here are some popular CI/CD tools that support Docker:

- Jenkins: Jenkins is an open-source automation server that supports Docker out of the box. You can use Jenkins to build Docker images, run tests, and deploy containers to production.
- CircleCI: CircleCI is a cloud-based CI/CD platform that provides native support for Docker. It allows you to define your build and deployment pipeline using a configuration file and automatically builds and deploys Docker images on every commit.
- Travis CI: Travis CI is a cloud-based CI/CD platform that integrates with GitHub. It supports Docker and allows you to define your build and deployment steps using a configuration file.

Angular and Docker: Containerizing Your App

This tutorial will guide you through the process of deploying an Angular app to the cloud using Heroku. We will start by setting up a Heroku account and installing the Heroku CLI. Then, we will prepare our Angular app for deployment by building it and configuring the package.json file. Next, we will deploy the app to Heroku by initializing a Git repository and pushing the app to Heroku. We will also cover how to set up environment variables, test the deployment, troubleshoot common issues, and scale the app. By the end of this tutorial, you will have a fully deployed Angular app running on Heroku.

![angular heroku deploying cloud](https://dopebase.com/media/cover2.jpg)
## Introduction

### What is Angular?

Angular is a popular JavaScript framework for building web applications. It provides a powerful set of tools and features that make it easy to build scalable and maintainable applications. Angular follows the model-view-controller (MVC) architectural pattern and uses HTML templates, TypeScript, and dependency injection to create dynamic and responsive web pages.

### What is Heroku?

Heroku is a cloud platform that allows you to deploy, manage, and scale web applications. It supports various programming languages and frameworks, including Angular. Heroku provides a simple and intuitive interface for managing your applications and offers a range of add-ons and services to enhance your app's functionality.

### Why deploy Angular to the cloud?

Deploying your Angular app to the cloud has several advantages. First, it allows you to easily share your app with others by providing a public URL. Second, it allows you to scale your app to handle a large number of users without the need for additional infrastructure. Finally, deploying to the cloud provides a reliable and secure hosting environment, ensuring that your app is always available to users.

## Setting up Heroku

### Creating a Heroku account

Before we can deploy our Angular app to Heroku, we need to create a Heroku account. Go to the Heroku website (https://www.heroku.com/) and click on the "Sign up" button. Fill in the required information and click on the "Create free account" button. You will receive an email with a verification link. Click on the link to verify your account.

### Installing the Heroku CLI

To interact with Heroku from the command line, we need to install the Heroku CLI. Open your terminal or command prompt and run the following command:

```
$ npm install -g heroku
```

This will install the Heroku CLI globally on your system. Once the installation is complete, you can verify it by running the following command:

```
$ heroku --version
```

### Creating a new Heroku app

Now that we have the Heroku CLI installed, we can create a new Heroku app. Open your terminal or command prompt and navigate to the root directory of your Angular app. Run the following command to create a new Heroku app:

```
$ heroku create
```

This will create a new Heroku app and associate it with your Heroku account. You will see the app's URL and Git repository URL displayed in the terminal.

## Preparing the Angular App

### Building the Angular app

Before we can deploy our Angular app to Heroku, we need to build it. This will compile the TypeScript code, bundle the JavaScript and CSS files, and create the necessary assets for the app to run. Open your terminal or command prompt and navigate to the root directory of your Angular app. Run the following command to build the app:

```
$ ng build --prod
```

This will build the app in production mode and generate the necessary files in the "dist" directory.

### Configuring the package.json file

To deploy our Angular app to Heroku, we need to configure the package.json file. This file contains information about the app, its dependencies, and scripts to run various tasks. Open the package.json file in the root directory of your Angular app and add the following scripts:

```json
"scripts": {
  "start": "node server.js"
}
```

This script tells Heroku to start the app by running the "server.js" file. We will create this file in the next section.

### Adding a server.js file

To deploy our Angular app to Heroku, we need to add a server.js file. This file will serve as the entry point for our app and handle the HTTP requests. Create a new file called "server.js" in the root directory of your Angular app and add the following code:

```javascript
const express = require('express');
const app = express();
const path = require('path');

app.use(express.static(__dirname + '/dist'));

app.get('/*', function(req,res) {
  res.sendFile(path.join(__dirname+'/dist/index.html'));
});

app.listen(process.env.PORT || 8080);
```

This code sets up a basic Express server that serves the static files from the "dist" directory and redirects all other requests to the "index.html" file. The "process.env.PORT || 8080" part ensures that the app listens on the correct port, whether it is provided by Heroku or the default port of 8080.

## Deploying to Heroku

### Initializing a Git repository

Before we can deploy our Angular app to Heroku, we need to initialize a Git repository. Open your terminal or command prompt and navigate to the root directory of your Angular app. Run the following command to initialize a Git repository:

```
$ git init
```

This will create a new Git repository in the current directory.

### Pushing the app to Heroku

Now that we have a Git repository, we can push our app to Heroku. Run the following command to add the Heroku remote repository:

```
$ heroku git:remote -a <your-app-name>
```

Replace "<your-app-name>" with the name of your Heroku app. This will add a new remote repository called "heroku" to your Git repository.

Next, run the following command to push the app to Heroku:

```
$ git push heroku master
```

This will upload the app's files to Heroku and trigger the deployment process. You will see the build logs in the terminal.

### Setting up environment variables

To configure environment variables for our Angular app on Heroku, we can use the Heroku CLI or the Heroku Dashboard. For simplicity, we will use the Heroku Dashboard in this tutorial.

1. Go to the Heroku Dashboard (https://dashboard.heroku.com/) and log in.
2. Select your app from the list of apps.
3. Click on the "Settings" tab.
4. Scroll down to the "Config Vars" section.
5. Click on the "Reveal Config Vars" button.
6. Add any environment variables that your app requires, such as API keys or database connection strings.

## Testing the Deployment

### Accessing the deployed app

Once the deployment process is complete, you can access your deployed Angular app by visiting the URL provided by Heroku. Open your web browser and enter the URL in the address bar. You should see your app running.

### Checking logs and error handling

To check the logs of your deployed app on Heroku, you can use the Heroku CLI or the Heroku Dashboard. For simplicity, we will use the Heroku Dashboard in this tutorial.

1. Go to the Heroku Dashboard (https://dashboard.heroku.com/) and log in.
2. Select your app from the list of apps.
3. Click on the "More" button in the top-right corner.
4. Select "View logs" from the dropdown menu.
5. This will open the logs page, where you can view the logs of your app and troubleshoot any errors or issues.

### Scaling the app

To scale your deployed Angular app on Heroku, you can use the Heroku CLI or the Heroku Dashboard. For simplicity, we will use the Heroku Dashboard in this tutorial.

1. Go to the Heroku Dashboard (https://dashboard.heroku.com/) and log in.
2. Select your app from the list of apps.
3. Click on the "Resources" tab.
4. Under the "Dynos" section, click on the "Edit" button.
5. Adjust the number of dynos to scale your app up or down.
6. Click on the "Save" button to apply the changes.

## Troubleshooting

### Common deployment issues

Deploying an Angular app to Heroku can sometimes have issues. Here are some common deployment issues and their solutions:

- **Error: "No default language could be detected for this app."**: This error occurs when Heroku cannot detect the programming language of your app. To fix this, make sure that your app's root directory contains a valid package.json file.

- **Error: "Error: Cannot find module 'express'"**: This error occurs when the Express module is not installed. To fix this, make sure that you have installed the Express module by running the following command: `$ npm install express --save`.

### Debugging tips

If you encounter any issues during the deployment process, here are some debugging tips:

- Check the build logs for any error messages or stack traces. These can provide valuable information about what went wrong.

- Verify that your app's dependencies are correctly specified in the package.json file.

- Check that your app's entry point file (e.g. server.js) is correctly configured and located in the root directory of your app.

By the end of this tutorial, you will be able to deploy your Angular app to Vercel, set up a custom domain, enable SSL, and automate deployments using GitHub integration.

![angular vercel deploying apps](https://dopebase.com/media/cover7.jpg)
## Introduction

### What is Angular?

Angular is a TypeScript-based open-source framework for building web applications. It is maintained by Google and provides a comprehensive set of features for developing dynamic, robust, and scalable applications. Angular uses a component-based architecture and provides tools for managing state, routing, and data binding. It also offers a powerful CLI (Command Line Interface) for creating and managing Angular projects.

### What is Vercel?

Vercel is a cloud platform designed to make it easy to deploy and host frontend applications. It provides serverless deployment for static websites and frontend applications, allowing you to focus on building your app without worrying about infrastructure. Vercel supports various frameworks and tools, including Angular, React, Vue.js, and Next.js. It offers features like custom domains, SSL certificates, and continuous deployment.

### Setting Up Angular Project

To get started, we need to set up an Angular project.

#### Installing Angular CLI

Angular CLI is a command-line interface for creating and managing Angular projects. To install Angular CLI, open your terminal or command prompt and run the following command:

```
npm install -g @angular/cli
```

This will install Angular CLI globally on your system.

#### Creating a new Angular project

Once Angular CLI is installed, you can create a new Angular project by running the following command:

```
ng new my-angular-app
```

This will create a new directory named `my-angular-app` and generate the basic structure of an Angular project inside it.

#### Building Angular App

To build your Angular app, navigate to the project directory and run the following command:

```

This will compile your Angular app and generate a production-ready build inside the `dist` directory. The `--prod` flag ensures that the build is optimized for production.

### Creating components

In Angular, components are the building blocks of an application. They encapsulate the logic and UI of a specific part of your app. To create a new component, run the following command:

```
ng generate component my-component
```

This will generate a new component named `my-component` along with its template, styles, and test files. You can then use this component in your app by adding its selector to a parent component's template.

### Defining routes

In Angular, routing is used to navigate between different views or pages of an application. To define routes in your Angular app, open the `app-routing.module.ts` file and add the following code:

```typescript
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { AboutComponent } from './about/about.component';

const routes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'about', component: AboutComponent },
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }
```

In this code, we import the necessary modules and define an array of routes. Each route is an object with a `path` property that represents the URL and a `component` property that represents the component to be displayed when the URL matches the path. We then configure the routes using the `RouterModule.forRoot()` method and export the `RouterModule` module.

### Implementing services

Services are used in Angular to share data or functionality between components. To create a new service, run the following command:

```
ng generate service my-service
```

This will generate a new service named `my-service` along with its test file. You can then use this service in your components by injecting it into their constructors.

## Deploying Angular App to Vercel

Now that we have our Angular app ready, let's deploy it to Vercel.

### Creating Vercel account

To deploy your Angular app to Vercel, you need to create a Vercel account. Go to the Vercel website (https://vercel.com/) and sign up for an account. Once you have an account, you can proceed to the next step.

### Installing Vercel CLI

Vercel CLI is a command-line interface for deploying and managing projects on Vercel. To install Vercel CLI, open your terminal or command prompt and run the following command:

```
npm install -g vercel
```

This will install Vercel CLI globally on your system.

### Configuring Vercel deployment

To configure the deployment of your Angular app to Vercel, navigate to the project directory and run the following command:

```
vercel
```

This will start the Vercel deployment wizard. Follow the prompts to configure your deployment. You will be asked to log in to your Vercel account, select the project directory, and choose the deployment settings. Once the configuration is complete, Vercel will deploy your app and provide you with a unique URL.

## Custom Domain and SSL

To make your Angular app accessible through a custom domain and enable SSL, follow these steps.

### Setting up custom domain

To set up a custom domain for your Angular app deployed on Vercel, go to the Vercel dashboard and select your project. Navigate to the "Settings" tab and click on "Domains". Enter your custom domain and click on "Add". Follow the instructions provided by Vercel to configure your DNS settings and point your domain to Vercel.

### Enabling SSL

Vercel provides automatic SSL certificates for custom domains. Once your custom domain is set up, Vercel will automatically provision and renew SSL certificates for your domain. This ensures that your Angular app is served over HTTPS and is secure.

## Continuous Deployment

To automate the deployment of your Angular app on Vercel whenever you push changes to your GitHub repository, follow these steps.

### Setting up GitHub integration

To set up GitHub integration with Vercel, go to the Vercel dashboard and select your project. Navigate to the "Settings" tab and click on "Git". Click on "Set up Git integration" and follow the prompts to connect your GitHub account and select the repository for your Angular app.

### Automating deployments

Once GitHub integration is set up, Vercel will automatically deploy your Angular app whenever you push changes to your GitHub repository. This allows you to focus on development and ensures that your app is always up to date.

## Conclusion

In this tutorial, we learned how to deploy Angular apps using Vercel. We started by setting up an Angular project and building the app. Then, we created components, defined routes, and implemented services in our app. Next, we deployed our Angular app to Vercel by creating a Vercel account, installing Vercel CLI, and configuring the deployment. We also learned how to set up a custom domain, enable SSL, and automate deployments using GitHub integration. By following these steps, you can easily deploy your Angular apps and take advantage of the powerful features provided by Vercel. Happy deploying!
