3. Connect to the EC2 instance: Once your instance is up and running, you need to connect to it. AWS provides various methods like SSH key pairs or AWS Systems Manager Session Manager to connect to EC2 instances. Follow the AWS documentation for connecting to your EC2 instance.
4. Install Node.js: Once you are connected to your instance, install Node.js as it is a prerequisite for running AngularJS. Use the package manager appropriate for your operating system (such as apt-get for Ubuntu or yum for Amazon Linux) to install Node.js.
5. Install Angular CLI: After Node.js is installed, use the Node Package Manager (npm) to install Angular CLI, which is a command-line interface tool used to create and manage Angular projects. Run the following command: npm install -g @angular/cli This will install Angular CLI globally on your EC2 instance.
6. Create a new Angular project: With Angular CLI installed, you can now create a new Angular project. Navigate to the folder where you want to create the project and run the following command: ng new my-angular-project Replace "my-angular-project" with your desired project name.
7. Build and run the Angular project: Once the project is created, navigate to the project's folder using the cd command and use Angular CLI to build and run the project. Run the following commands: cd my-angular-project ng serve --host 0.0.0.0 --port 8080 This will start the Angular development server, allowing you to access the Angular application through port 8080 on your EC2 instance.
8. Access the Angular application: Finally, open a browser and enter the public IP address or DNS name of your EC2 instance, followed by port 8080 (e.g., http://your-ec2-instance-public-ip:8080). You should be able to see your Angular application running.

Remember to follow security best practices, such as configuring appropriate inbound and outbound rules in your EC2 instance's security group, to ensure the security and accessibility of your Angular application on AWS.

Here are the steps to run an AngularJS project on AWS:

Step 1: Launch an EC2 instance

• Log in to your AWS Console and navigate to the EC2 service.
• Click on the "Launch Instance" button and select a suitable Amazon Machine Image (AMI) for your project, such as an Ubuntu Server.
• Follow the on-screen instructions to configure the instance details, such as the instance type, network settings, and storage.
• Review and edit your security group settings to allow incoming traffic on port 80 or 443 for HTTP or HTTPS, respectively.

Step 2: Connect to the EC2 instance

• Once the instance is launched, you can connect to it using SSH.
• Retrieve the public IP address or public DNS of your EC2 instance from the AWS Console.
• Open your terminal or command prompt and run the following command:

1

ssh -i <path-to-your-key-pair-file> ubuntu@<public-ip-address-or-public-dns>

Step 3: Install Node.js and Nginx

• Install Node.js on the EC2 instance by running the following commands:

1
2
3

sudo apt update
sudo apt install nodejs
sudo apt install npm

• Install Nginx as a reverse proxy server to serve the AngularJS project:

1

sudo apt install nginx

• Start the Nginx service:

1

sudo systemctl start nginx

Step 4: Upload and deploy the project

• Copy the AngularJS project files to the EC2 instance using SCP or a similar tool.

1

scp -i <path-to-your-key-pair-file> -r <path-to-your-project> ubuntu@<public-ip-address-or-public-dns>:~

• Connect to the EC2 instance again using SSH.
• Move your project files to the Nginx web root directory:

1

sudo mv <project-folder> /var/www/html/

Step 5: Configure Nginx to serve the AngularJS project

• Edit the default Nginx configuration file:

sudo nano /etc/nginx/sites-available/default

• Inside the server block, update the root directive to point to your project folder:

1
2
3
4

server {
    ...
    root /var/www/html/<project-folder>;
}

• Save the file and exit the editor.
• Restart the Nginx service:

1

sudo systemctl restart nginx

Step 6: Access your AngularJS project

• In your web browser, visit the public IP address or public DNS of your EC2 instance.
• You should see your AngularJS project running on AWS.

Note: Make sure to configure any necessary routing or DNS settings, such as associating a domain name with your EC2 instance, if required.

What is Node.js and why is it required for AngularJS?

Node.js is an open-source, cross-platform runtime environment that executes JavaScript code outside of a web browser. It allows developers to use JavaScript for server-side scripting, enabling the building of dynamic web applications.

AngularJS, on the other hand, is a JavaScript framework that is primarily used for building single-page web applications. It provides a structure for organizing and managing the application's flow, data binding, communications, and more.

Node.js is required for AngularJS development in certain scenarios, such as server-side rendering. With server-side rendering, the initial rendering of the web page happens on the server before being sent to the client's browser. This can enhance performance and improve search engine optimization (SEO).

Additionally, Node.js is often used with AngularJS during development for tasks like running a local development server, automating build processes, managing dependencies, and running tests. Tools like npm (Node Package Manager) are heavily used in the AngularJS ecosystem, which relies on Node.js to manage and install dependencies.

In summary, Node.js is required for AngularJS to leverage various development tools and practices, facilitate server-side rendering, and enhance the overall development workflow.

What is the default port for an AngularJS application?

There is no default port specifically for an AngularJS application. The port on which an AngularJS application runs is determined by the server hosting the application. By default, most servers use port 80 for HTTP and port 443 for HTTPS. However, developers have the flexibility to configure the server to use a different port if desired.

How to start the local development server for an AngularJS project on AWS?

To start the local development server for an AngularJS project on AWS, you can follow these steps:

1. Install Node.js: If you haven't already done so, install Node.js on your local machine. You can download it from the official website and follow the installation instructions for your operating system.
2. Install Angular CLI: Open your terminal or command prompt and run the following command to install the Angular CLI globally: npm install -g @angular/cli.
3. Set up your Angular project: Navigate to your project directory in the terminal or command prompt and run the following command to initialize a new Angular project: ng new my-angular-project. This will create a new Angular project folder with all the necessary files and dependencies.
4. Navigate to the project directory: Use the cd command to navigate to the newly created project directory: cd my-angular-project.
5. Start the local development server: Run the following command to start the local development server: ng serve. By default, the server will listen on http://localhost:4200/.
6. Access your Angular app: Open your web browser and navigate to http://localhost:4200/. You should see your Angular app running on the local development server.

Note: If you encounter any errors during the installation or start-up process, make sure you have followed all the necessary steps correctly and check the official Angular documentation for troubleshooting.
