Setting Up Your Development Environment

In this second chapter, we will dive into the crucial task of setting up your development environment to build Angular applications with PrimeNG components. This chapter equips you with the necessary knowledge and tools to create a seamless and productive development environment. From installing the required software to understanding the project structure, we will guide you through each step to ensure a smooth setup process.

By the end of this chapter, you will have a well-configured development environment and will be equipped with the necessary tools to start building Angular applications with PrimeNG. Understanding the technical requirements, setting up the Angular CLI, and familiarizing yourself with the project structure will lay a solid foundation for your web development journey. Additionally, leveraging an IDE such as VS Code and utilizing useful extensions will boost your productivity and make the development process more efficient.

So, let’s dive in and set up your development environment for an optimal Angular development experience. In this chapter, we will cover the following topics:

Setting up the Angular CLICreating a new Angular projectUnderstanding the project structureDiscovering useful VS Code extensions

Technical requirements

The chapter contains various code samples from a new Angular project. You can find the related source code in the chapter-02 folder of the following GitHub repository:.

Before diving into the setup process, it’s important to ensure that your system meets the necessary technical requirements for development. Let’s take a look at the key components you’ll need to have in place:

Node.js (NVM): Install Node.js, a JavaScript runtime, using Node Version Manager (NVM) to manage multiple Node.js versions on your system. You can download and install NVM from the official website: https://github.com/nvm-sh/nvm. If your company imposes restrictions on the usage of NVM, please refer to the official Node.js website (https://nodejs.org) for installation instructions and follow the provided guide.npm: Choose npm for managing dependencies in your Angular projects. It comes bundled with Node.js, so if you have Node.js installed, you will be able to use npm. If you prefer to use alternatives to npm, you can check out either Yarn (https://yarnpkg.com) or pnpm (https://pnpm.io).GitHub: Sign up for a GitHub account to leverage this web-based hosting service for version control and collaboration. GitHub allows you to track changes, collaborate with team members, and host your Angular repositories. Sign up for an account at https://github.com.VS Code (Visual Studio Code): Install VS Code, a free and extensible source-code editor developed by Microsoft. VS Code offers built-in support for Angular and integrates seamlessly with the Angular CLI, providing features such as code completion and debugging. Download VS Code from the official website: https://code.visualstudio.com.

By ensuring that you have Node.js (NVM), a package manager (npm, Yarn, or pnpm), GitHub, and VS Code installed, you’ll have a solid foundation for setting up your Angular development environment. These tools will enable you to efficiently build, manage, and collaborate on your Angular projects with PrimeNG components.

Setting up the Angular CLI

The Angular CLI (Command-Line Interface) is a powerful tool that simplifies the process of creating, developing, and maintaining Angular applications. It provides a set of commands that automate common development tasks, allowing you to focus on building your application rather than setting up the project structure manually. In this section, we will guide you through the installation process of the Angular CLI and provide an overview of its core commands.

Note

Ensure that you have a stable internet connection during the installation process. It may take some time to download and install the required packages, depending on your internet speed.

Installing Node.js v18 (using NVM)

To install NVM and set Node.js v18 as the default version, follow these steps:

Visit the official NVM repository on GitHub: https://github.com/nvm-sh/nvm.Follow the installation instructions specific to your operating system. This typically involves running a script to download and install NVM. The following script will help to download and install NVM v0.39.3: curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

Note

The version of NVM may change, so please visit the official website for the latest version and instructions.

Open a new terminal window or restart your terminal to load NVM.Run the following command to verify that NVM is installed: nvm --version // result 0.39.3

You should see the version number of NVM printed in the terminal. In this example, the current version is 0.39.3.

After that, run the following command to install Node.js v18 using NVM: nvm install 18In order to use Node.js v18 in a new terminal session, we need to set Node.js v18 as the default version. To do that, run the following command: nvm alias default 18Finally, run the following commands to verify that Node.js v18 is installed and set as the default: node --version npm --version

These commands should display the version numbers of Node.js and npm respectively, and they should correspond to the installed Node.js v18.

With Node.js v18 installed, let’s move on to installing the Angular CLI.

Installing the Angular CLI

To install the Angular CLI, complete the following instructions depending on your operating system.

For Windows machines, do the following:

Open Command Prompt or PowerShell.Run the following command to install the Angular CLI globally: npm install -g @angular/cli

For Linux/macOS machines, do the following:

Open Terminal.Run the following command to install the Angular CLI globally: npm install -g @angular/cli

Note

If you encounter permission errors while installing Node.js or the Angular CLI using the npm package manager, you may need to use sudo before the commands to run them with administrator privileges.

For macOS (using Homebrew), dothe following:

Open Terminal.Install Homebrew by running the following command: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)Once Homebrew is installed, run the following command to install Node.js: brew install angular-cli

After following the appropriate installation process for your system, confirm the version of the Angular CLI with this command:

ng version

You will receive the output shown in Figure 2.1. As you can see, at the time of writing this book, the version of the Angular CLI is 17.0.6.

Figure 2.1 – The Angular CLI version

The Angular CLI provides a wide range of commands to streamline the development process. Here are some of the most commonly used commands and their explanations:

ng new [project-name]: Creates a new Angular project with the specified name. It sets up the project structure, installs dependencies, and generates initial boilerplate code.ng serve: Starts a development server and compiles your Angular application. It watches for changes in your files and automatically reloads the application in the browser.ng generate [schematic] [name]: Generates different elements of your Angular application such as components, services, modules, and more. It scaffolds the necessary files and updates the required configurations.ng build: Builds the Angular application for production. It compiles the code and generates optimized files that can be deployed to a web server.ng test: Executes unit tests for your Angular application. It runs the tests using the configured test runner and provides detailed information about test results.ng lint: Analyzes the code for potential errors and code style violations. It helps enforce coding standards and maintain code quality.ng deploy: Deploys your Angular application to a hosting platform, such as GitHub Pages or Firebase Hosting. It automates the deployment process and makes your application accessible to the public.

Note

You can run ng help to see the list of commands and their usage. You can also check the official documentation for an overview of all commands at https://angular.io/cli#command-overview.

By leveraging the Angular CLI, you can streamline your development workflow, automate repetitive tasks, and focus on building high-quality Angular applications. The installation process on Windows, Linux, and macOS, including an alternative option using Homebrew for macOS, ensures that you have the necessary tools to harness the power of the Angular CLI.
