Angular has quickly become one of the most popular frameworks for building web applications, thanks to its robust set of features and ease of use. Angular is developed and maintained by Google. It offers a comprehensive solution for developing modern, dynamic web applications that are both scalable and maintainable.
In this guide, we’ll explore everything you need to know about Angular. We’ll start with its background and importance in the realm of web development, then proceed to a step-by-step tutorial on how to install Angular on Linux VPS.
What is Angular?
It is designed to make the development and testing of dynamic web applications easier and more efficient. It uses TypeScript, a statically typed superset of JavaScript, which helps developers catch errors early and write more robust code.
Angular is renowned for its powerful features, including two-way data binding, dependency injection, and a component-based architecture. These features simplify the development process by promoting code reuse, improving testability, and enhancing overall application performance.
Who Uses Angular?
It is utilized by a diverse range of developers and organizations, including individual web developers, startups, and large enterprises. Its robust framework is ideal for building dynamic, single-page applications and complex enterprise-level systems. Major companies such as Google, Microsoft, and IBM leverage Angular for its scalability, maintainability, and comprehensive toolset. Additionally, cross-platform developers use Angular in conjunction with frameworks like Ionic to create mobile applications, while real-time application developers take advantage of Angular’s seamless integration with real-time data services.
Advantages of using Angular
Component-Based Architecture
Angular’s components facilitate code reuse, modularity, and maintenance. Each component encapsulates its logic and UI, promoting a clean and organized codebase.
Two-Way Data Binding
This feature automatically synchronizes the model and view, reducing the amount of repitative code and simplifying the development process.
Dependency Injection
Angular’s DI system makes it easy to manage dependencies, improve code modularity, and enhance testing capabilities.
Powerful CLI
The Angular CLI offers commands for generating, building, testing, and deploying applications, significantly speeding up the development workflow.
TypeScript Support
TypeScript’s static typing, advanced features, and improved tooling contribute to better code quality and developer productivity.
Rich Ecosystem
Angular has a vibrant community and a wealth of third-party libraries, extensions, and tools that extend its functionality and simplify common development tasks.
Prerequisites
Basic Knowledge of Web Development
-> Understanding of HTML, CSS, and JavaScript is essential.
->Familiarity with TypeScript, as this is built using TypeScript.
Node.js and npm Installed
-> Requires Node.js, a JavaScript runtime, and npm to manage its dependencies.
Code Editor
-> A code editor or Integrated Development Environment (IDE) such as Visual Studio Code, WebStorm, or Sublime Text.
Basic Understanding of CLI
-> Familiarity with command-line interface (CLI) operations, as Angular uses its own CLI for project setup, development, and deployment.
System requirements
->Processor: Dual-core CPU (Quad-core or higher recommended)
->Memory: 4 GB RAM (8 GB or higher recommended for large projects and smoother performance)
->Storage: At least 10 GB of free disk space (more may be required for larger projects and additional dependencies)
How to Install on Linux
Setting up Angular on both Windows and Linux is straightforward and essential for building dynamic web applications. Next we can discuss installation process for each operating system.
1. You need to update your server before installing th erequired package
apt update
apt upgrade2. Install Node.js and npm
Additionally it requires Node.js and npm (Node Package Manager). Navigate to our detailled installation guide to install node.js and NPM on linux. To verify installation,
node -v
npm -v3. Install Angular CLI
Once Node.js and npm are installed, install the CLI globally using npm.
npm install -g @angular/cli4. Verify Angular CLI Installation
Check if the CLI is installed correctly by verifying its version.
ng --version5. Create a New Project
Now, you can create a new project using the Angular CLI.
ng new my-angular-app6. Navigate to the Project Directory
Move into the newly created project directory.
cd my-angular-app7. Serve the Application
Use the Angular CLI to serve the application locally.
ng serve --openThis command compiles the application and opens it in your default web browser. Specifically, the server runs on port 4200. Therefore, you have to open port 4200 on your server. Consequently, your Angular application should now be running at http://localhost:4200.
