How to Install Angular on Windows (Step by Step)

To install Angular, first ensure that Node.js and npm (Node Package Manager) are installed on your system, as Angular relies on them. You can download Node.js, which includes npm, from the Node.js website. After installing, check the versions with node -v, and npm -v to confirm they're set up correctly. Next, install Angular CLI (Command Line Interface) globally by running npm install -g @angular/cli in your terminal. This tool simplifies Angular project creation and management. To create a new Angular project, navigate to your desired directory and execute ng new project-name, replacing project-name with your chosen name. 

‍

This command sets up a new Angular application with a default configuration. Once the project is created, enter the project folder using cd project-name, and start the development server by running ng serve. You can then view your Angular application by opening http://localhost:4200 in a web browser. This process provides you with a fully functional Angular development environment. To install Angular, ensure Node.js and npm are installed. 

‍

Download them from the Node.js website, then verify the installation with node -v and npm -v. Install Angular CLI globally using npm install -g @angular/cli. Create a new project with ng new project name, replacing the project name with your preferred name. Navigate to your project folder with cd project-name and start the development server using ng serve. Access your Angular app by visiting http://localhost:4200 in your web browser. This setup enables you to begin developing Angular applications with ease.

‍

What is Node.js?

Node.js is an open-source, cross-platform runtime environment that allows you to execute JavaScript code outside of a web browser. It’s built on Chrome's V8 JavaScript engine and is designed for building scalable network applications. Unlike traditional web servers that handle multiple requests in a single thread, Node.js uses an event-driven, non-blocking I/O model, which makes it highly efficient and suitable for real-time applications like chat services, online gaming, and live streaming.

‍

Node.js also includes a package manager called npm (Node Package Manager), which provides access to a vast repository of libraries and tools that simplify the development of JavaScript applications.

‍

With its robust ecosystem and ability to handle a large number of simultaneous connections, Node.js is widely used for server-side development, building APIs, and automating tasks in various types of applications.

Prerequisites to Install Angular in Windows

To install Angular on Windows, first ensure you have Node.js and npm installed, as they are required for running Angular CLI. Familiarity with command-line tools and having a text editor or IDE will enhance your development experience.

‍

Make sure you have administrative rights and a stable internet connection for downloading and setting up the necessary software. With these prerequisites in place, you're ready to start developing Angular applications.

‍

Before installing Angular on a Windows system, ensure you have the following prerequisites:

• Node.js and npm: Angular requires Node.js and npm (Node Package Manager). Download and install the latest version of Node.js from the Node.js website. npm comes bundled with Node.js. Verify the installation by running node -v and npm -v in your command prompt.

• Command Line Interface (CLI) Knowledge: Basic familiarity with command-line operations is helpful, as Angular CLI commands are executed through the terminal.

• Text Editor or IDE: While not mandatory, having a text editor or Integrated Development Environment (IDE) like Visual Studio Code, Sublime Text, or Atom can make development easier by providing syntax highlighting, code completion, and debugging tools.

• Administrator Rights: Installing Node.js and Angular CLI might require administrative privileges, so ensure you have the necessary rights or run the installer as an administrator.

• Stable Internet Connection: An internet connection is needed to download Node.js, npm packages, and Angular CLI.

‍

Once these prerequisites are in place, you can proceed to install Angular and start developing Angular applications on your Windows machine.

‍

Creating A New Angular Project

To get started with Angular, the first step is to generate a new project using Angular CLI (Command Line Interface). This command sets up a fresh Angular application with a standard directory structure and essential configuration files.

‍

Generate a New Project

• Command to create a new Angular project

ng new my-angular-app

‍

Navigate to the Project Directory

• Command to change directory into the project folder

cd my-angular-app

‍

Angular CLI Commands

Angular CLI (Command Line Interface) provides a range of commands to simplify Angular development. Here are some commonly used Angular CLI commands:

‍

Create a New Project:

ng new project-name

‍

• Initializes a new Angular project with the specified name.

‍

Serve the Application:

ng serve

‍

• Compiles the application and starts a development server. By default, the application is accessible at http://localhost:4200.

• Generate Components, Services, and Other Code:

‍

Component:

ng generate component component-name

‍

Service:

ng generate service service-name

‍

Directive:

ng generate directive directive-name

‍

Pipe:

ng generate pipe pipe-name

‍

Module:

ng generate module module-name
