Complete Beginner’s Guide to Angular: Create Modern Web Applications

If you’re new to the world of web development and looking to create modern, dynamic web applications, Angular is an excellent choice. Developed by Google, Angular is a popular enterprise JavaScript framework that offers a comprehensive set of tools and features to simplify web development.

What is Angular?

Angular is an open-source JavaScript framework for building feature-rich web applications. It stands out for its modularity, responsiveness and ability to handle complex applications. Here are some key points to remember about Angular:

1. Angular components

Angular is based on a component model, where each element of the user interface is a reusable component. This simplifies the creation and maintenance of your application. A component is a self-contained unit that combines an HTML template, CSS styles and a TypeScript class to manage logic and behavior.

Creating components

To create an Angular component, use the following Angular CLI command:

2. Data Link

Angular offers bidirectional data binding, meaning that changes in the user interface are automatically reflected in the data model and vice versa. This simplifies data management and improves your application’s responsiveness.

One-way Data Link

The one-way data link transfers component data to the HTML template. Changes in the data model are reflected in the user interface.

Bidirectional Data Link

The bidirectional data link synchronizes data between the component and the template. Changes in the user interface are also reflected in the data model.

3. Angular services

Services are used to share data and functionality between different components of your application. They are commonly used to manage communication with a server, store shared data and perform complex operations.

Creating services

To create an Angular service, use the following Angular CLI command:

4. Routing in Angular

Angular includes a routing system for navigating between different pages of your application without reloading the page. You can define routes, URL parameters and navigation gatekeepers to control access to your application’s pages.

Routing configuration

To configure routing in Angular, define routes in a configuration file. Specify the component associated with each route and define the corresponding paths.

5. Angular form management

Angular makes it easy to create and validate forms, whether for data collection or user input. You can create responsive forms that deliver a fluid, interactive user experience.

Creating Reactive Forms

Reactive forms allow you to manage form data reactively. You can define personalized validators and react to user modifications in real time.

6. Communication with a Server

Use services to make HTTP requests to a server. Learn how to manage server responses, manipulate data from the server and handle errors.

HTTP requests

Angular offers an HTTP module for making requests to remote APIs. You can carry out GET, POST, PUT, DELETE and other requests.

7. Test and Deploy

Test your application using the test tools provided by Angular CLI. Once your application is ready, use Angular CLI to generate an optimized production version that you can deploy on a web server.

Test Tools

Angular CLI includes test tools for components, services and routes. You can write unit tests and integration tests to ensure the quality of your code.
