How to create an app on Angular

Daphnie Ozioma

Angular is a popular Javascript framework for front-end development. It is opinionated and comes with out-of-the-box tools for building fast and scalable web, desktop, and mobile applications.

Angular is a powerful Javascript framework

Prerequisites

To use the Angular framework, you need a basic understanding of the following:

  • HTML
  • CSS
  • JavaScript
  • TypeScript

You need to have Node installed on your computer.

Let’s get started

To start a new Angular application, you need to:

Install the Angular CLI

If you have previously installed the CLI tool, you can skip this step. Otherwise, open a terminal and run the following command:

npm install -g @angular/cli

This command installs the latest version of Angular’s CLI on your computer. With the -g flag, we can tell npm to install the CLI globally. This will make it possible to run the CLI command from anywhere on your computer.

You can access the Angular CLI using the ng keyword.

Bootstrap a new app

ng new angular-app

The ng new command creates a basic Angular app. The CLI prompts you about features to include in your app, installs the necessary dependencies, and configures your project based on your choices.

The bootstrapped app contains a few source and configuration files to help you get developing quickly. Your application code resides in the src folder of the workspace.

Launch the application

cd angular-app
ng serve

Go into your project’s root folder using the cd command and launch the app. The ng serve command builds the app, starts the development server, watches the source files, and rebuilds the app as you make changes.
