Introduction:
Angular is a web application framework that allows for the creation of dynamic, single-page applications. In this article, we will look at how to install Angular and set up an initial project. We will also address some common questions and concerns about using Angular.
Section 1: Installation
Firstly, we need to make sure that Node.js and npm are installed on our machine. Node.js is a JavaScript runtime environment that allows us to run JavaScript on the server. Npm is a package manager for Node.js that allows us to easily install and manage packages.
To check if Node.js is installed, open the terminal/command prompt and type the following command:
node -v
This will return the version number if Node.js is installed. If it is not installed, download and install it from the Node.js website.
Next, we need to install the Angular CLI (Command Line Interface) using npm. Open the terminal/command prompt and type the following command:
npm install -g @angular/cli
This will install the latest version of the Angular CLI globally on our machine. We can now use the Angular CLI to create new Angular projects.
Section 2: Creating a new Angular project
To create a new Angular project, we can use the following command:
ng new my-app
This will create a new project named “my-app” in a new directory. We can then navigate into the new directory using the following command:
cd my-app
We can now run the project using the following command:
ng serve
This will compile the project and open it in our default web browser at http://localhost:4200.
