Angular is an frameworks, libraries, assets, and utilities. It keeps track of all the components and checks regularly for their updates. This tutorial will help you to install the Angular CLI tool on Debian 10 Buster, Debian 9 Stretch, and Debian 8 Linux systems.
Reference: Serve Node.js Application behind the Apache Server
Step 1 – Install Node.js
First of all, you need to install node.js on your system. Use the following commands to configure node.js PPA in your Debian system and install it.
sudo apt-get install software-properties-common curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash - sudo apt-get install nodejs
Make sure you have successfully installed node.js and NPM on your system
node --version npm --version
Step 2 – Install Angular/CLI on Debian
After finishing the Node.js installation on your system, use the following commands to install the Angular CLI tool on your system globally.
npm install -g @angular/cli
The above command will install the latest available Angular CLI version on your Debian system. To install specific Angular version run command as following with version number.
npm install -g @angular/[email protected]6 #Angular 6 npm install -g @angular/[email protected]7 #Angular 7 npm install -g @angular/[email protected]8 #Angular 8 npm install -g @angular/[email protected]9 #Angular 9
Using the -g above command will install the Angular CLI tool globally. So it will be accessible to all users and applications on the system. Angular CLI provides a command ng used for command-line operations. Let’s check the installed version of ng on your system.
ng --version / \ _ __ __ _ _ _| | __ _ _ __ / ___| | |_ _| / △ \ | '_ \ / _` | | | | |/ _` | '__| | | | | | | / ___ \| | | | (_| | |_| | | (_| | | | |___| |___ | | /_/ \_\_| |_|\__, |\__,_|_|\__,_|_| \____|_____|___| |___/ Angular CLI: 8.1.3 Node: 12.7.0 OS: linux x64 Angular: ... Package Version ------------------------------------------------------ @angular-devkit/architect 0.801.3 @angular-devkit/core 8.1.3 @angular-devkit/schematics 8.1.3 @schematics/angular 8.1.3 @schematics/update 0.801.3 rxjs 6.4.0
Step 3 – Create 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-angular4
Output:
...
...
added 1011 packages from 1041 contributors and audited 19005 packages in 55.774s
found 0 vulnerabilities
Successfully initialized git.
This will create a directory named hello-angular4 in your current directory, and create an application.
Step 4 – Serve Angular Application
Your basic Angular application is ready to serve. Change directory to hello-angular4 and run your Angular application using ng serve command.
cd hello-angular4 ng serve
You can access your angular application on localhost port 4200, Which is the default host and port used by Angular application.
- http://localhost:4200
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
The IP address 0.0.0.0 listens on all interfaces and publically accessible.
Conclusion
You have successfully installed Angular CLI and created a sample application. The next tutorial will help you to configure the Angular application behind the Apache server to serve with a domain name.
