sudo apt install python-software-properties
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt install nodejs

Step 2 – Install Angular/CLI

After installation of node.js and npm on your system, use following commands to install Angular cli tool on your system.

npm install -g @angular/cli

The -g flag will install the Angular CLI tool globally so that it will be accessible to all users and applications on the system.

The latest version of Angular CLI will be installed on your Ubuntu Linux system. You may require older Angular version on your machine. To install specific Angular version run command as following with version number.

npm install -g @angular/cli@6     #Angular 6
npm install -g @angular/cli@7     #Angular 7

Step 3 – Check Angular/CLI version

To verify the installation, check the version of Angular installed in your system using the ng command in Angular CLI:

ng --version

Step 4 – Create a New Angular Application

Now, create a new application named hello-angular4 using the Angular CLI tools. Execute the commands to do this:

ng new hello-angular

Step 5 – Serve Angular Application

cd hello-angular
ng serve

After compilation you can access your angular application on localhost port 4200, Which is the default host and port used by Angular application.

You can change host and port for running Angular application by providing –host and –port command line arguments.

ng serve --host 0.0.0.0 --port 8080
