Setting up Development Environment

Why a Proper Development Environment Matters

• Understanding the significance of a well-configured environment for Angular development.

Basic Requirements

• Prerequisites: Node.js, npm (Node Package Manager).
• Choosing a code editor: Visual Studio Code (recommended).

Step 2: Setting Up Node.js and npm

Installing Node.js

• Download and install the latest LTS version of Node.js from here.

• Verify the installation with node -v and npm -v commands.

Updating npm

• Update npm to the latest version using the npm install -g npm command.

Step 3: Installing Angular CLI

What is Angular CLI?

• The Angular Command Line Interface (CLI) is a powerful tool designed to streamline and accelerate the development of Angular applications. It offers a range of essential features and commands that simplify the entire development process. With the Angular CLI, developers can effortlessly generate components, modules, services, and more, reducing repetitive tasks and ensuring consistent project structures. Moreover, it provides an integrated development server for live previews, automatic code generation, and a robust testing environment. Overall, the Angular CLI empowers developers with a unified, efficient, and developer-friendly workflow, making it an indispensable companion for those seeking to build robust and scalable Angular applications with speed and precision.

Installing Angular CLI Globally

• Use npm to install Angular CLI globally with the command npm install -g @angular/cli.
• Verify the installation with ng --version.

Step 4: Creating Your First Angular Project

Generating a New Angular Project

• Use the Angular CLI to create a new project with ng new project-name.

Exploring Project Structure

• A newly created Angular project follows a well-organized project structure. At its core, you'll find a collection of directories and key files that form the foundation of your application. The 'src' folder contains the heart of your project, housing the Angular components, templates, styles, and application logic. The 'app' directory within 'src' is where you'll define your application's components, services, and modules. Key configuration files like 'angular.json' provide settings for the build and development environment, while 'package.json' keeps track of project dependencies and scripts. As you explore the project structure, you'll also encounter 'index.html,' your application's entry point, and 'main.ts,' the starting point for the Angular application. Understanding this project structure is crucial for efficiently organizing and developing Angular applications.

Step 5: Running the Development Server

Starting the Development Server

• Use ng serve to launch the development server.

Accessing Your Angular App

• Open a web browser and navigate to http://localhost:4200/ to view your app.
