Beginners Guide to Angular – Easy to Follow Tutorial with Examples
Angular is one of the most popular and powerful open-source web development frameworks currently available. It is used for building complex single-page web applications using a broad range of programming skills including HTML, CSS, and TypeScript. If you are just starting with Angular, then this beginners’ guide could be of great assistance to you.
In this guide, we provide you with a straightforward tutorial on how to get started with Angular, by walking you through the basics with easy to follow examples.
First things first, you need to have a basic understanding of HTML, CSS, and JavaScript concepts before you get started on Angular. But don’t worry – you do not need to be an expert in these areas to start with Angular.
What is Angular?
Angular is a framework that is designed to help developers build robust and feature-rich web applications. The framework is maintained by Google and has been in use since 2010. Angular makes application development easier as it provides an easy-to-use Model-View-Controller (MVC) architecture.
Here is a step-by-step guide on how to create your Angular application.
Step 1: Install Node.js and npm
Angular uses Node.js and its package manager, npm, to manage project dependencies and modules. Before installing Angular, you need to install Node.js and npm on your development machine.
Step 2: Install Angular CLI
Once you have installed Node.js and npm, the next step is to install the Angular command-line interface (CLI). To install Angular CLI, open your terminal or command prompt and type the following command:
“`
npm install -g @angular/cli
“`
This command installs the Angular CLI globally on your system.
Step 3: Create a new Angular app
Open your terminal or command prompt and run the following command to create a new Angular application:
“`
ng new my-app
“`
This command creates a new Angular application named `my-app`.
Step 4: Run the Angular app
Now run the Angular app by typing the following command:
“`
cd my-app
ng serve –open
“`
This command runs your Angular app in the browser at `http://localhost:4200/`.
Congratulations! You have created your first Angular app. Now let’s add some more features to it.
Step 5: Create a new component
In Angular, a component is a fundamental building block of an Angular app. To create a new component, run the following command:
“`
ng generate component my-component
“`
This command creates a new component named `my-component`.
Step 6: Add the component to the app
To add the newly created component to your app, open the `app.component.html` file and add the following code:
“`
“`
This code adds the new `my-component` to the root `app.component.html` file.
Step 7: Update the component
Open the `my-component.component.html` file and add the following HTML code:
“`
My Component
“`
This code adds a heading to the `my-component` component.
Step 8: Add styles to the component
Open the `my-component.component.css` file and add the following CSS code:
“`
h2 {
color: red;
}
“`
This code adds some basic styling to the `my-component` component.
Step 9: Run the app
Now run your app by typing the following command in your terminal or command prompt:
“`
ng serve –open
“`
This command runs your Angular app in the browser at `http://localhost:4200/`.
Conclusion
In this tutorial, we provided a beginner’s guide to Angular. We walked you through how to create an Angular application, generate a new component, and add it to the app. By following this easy to follow guide, you should now have a basic understanding of how to create an Angular app with components and styling.
While this guide provides an excellent starting point to learn Angular, there are many more features and concepts you may want to learn to build a more complex web application. With its vast documentation, community, and active development, Angular presents an outstanding opportunity for developers to build incredible web applications.
