Complete Angular Full Course: From Zero to Hero (Part 1) – A Comprehensive Tutorial

Introduction:
Angular is a popular JavaScript framework that is used for building dynamic web applications. In this tutorial, we will cover everything you need to know to become an Angular expert, from the basic concepts to advanced features. This is the first part of our complete Angular tutorial series, so let’s get started.

Prerequisites:
Before diving into Angular, you should have a basic understanding of HTML, CSS, and JavaScript. You should also have Node.js and npm(Node Package Manager) installed on your machine. If you do not have them installed, you can download and install them from the official Node.js website.

Getting Started with Angular:
To start building applications with Angular, you first need to install the Angular CLI (Command Line Interface). The Angular CLI makes it easy to create, build, and test your Angular applications.

To install the Angular CLI, open your terminal or command prompt and run the following command:

npm install -g @angular/cli

This command will install the Angular CLI globally on your machine. Once the installation is complete, you can create a new Angular project by running the following command:

ng new my-app

Replace ‘my-app’ with the name of your project. This command will create a new Angular project with the necessary files and folder structure.

Running the Angular Application:
To run your Angular application, navigate to the project directory using the terminal and run the following command:

cd my-app
ng serve

This command will start the development server, and you can access your Angular application in the browser at http://localhost:4200.

Now that you have set up your Angular project let’s dive into the core concepts of Angular.

Components:
Components are the building blocks of Angular applications. A component consists of a template, which defines the user interface, and a class, which contains the business logic.

To create a new component, run the following command in the terminal:

ng generate component my-component

This command will generate a new component with the name ‘my-component’ inside the ‘app’ directory. You can now use this component in your Angular application by importing it into other components or modules.

Services:
Services are used to provide shared functionality across your Angular application. Services are typically used to perform HTTP requests, share data between components, or perform any other business logic.

To generate a new service, run the following command in the terminal:

ng generate service my-service

This command will generate a new service with the name ‘my-service’ inside the ‘app’ directory. You can then inject this service into your components using Angular’s dependency injection system.

Routing:
Routing in Angular allows you to navigate between different components based on the URL. To set up routing in your Angular application, you need to define routes in the ‘app-routing.module.ts’ file.

Here is an example of how you can define routes in Angular:

const routes: Routes = [
{ path: ‘home’, component: HomeComponent },
{ path: ‘about’, component: AboutComponent },
{ path: ‘contact’, component: ContactComponent },
];

RouterModule.forRoot(routes);

With this configuration, you can navigate to ‘/home’, ‘/about’, and ‘/contact’ routes in your Angular application.

Conclusion:
In this tutorial, we covered the basics of Angular, including how to set up a new Angular project, create components, services, and set up routing. This is just the beginning of our Angular full course, and in the upcoming parts, we will dive deeper into more advanced concepts of Angular. Stay tuned for Part 2 of our Angular full course.
