Introduction

Welcome to this comprehensive discussion about the Agular tutorial. If you are a fan of JavaScript, it is highly probable for you to know angular tutorial. It would be easy to sail through angular if you have some basic knowledge of JavaScript. Angular is a trending framework used to develop different web applications.  This article will end you up with a decent knowledge of angular tutorial.

1. What is Angular? 

Angular is a Typescript framework and is often contended by google. Through this, one can develop huge applications easily. Angular offers a high performance by way of higher code quality. Check out this angular tutorial article to know about its features,  advantages and limitations so far.

2. What are angular forms, and how to implement them? 

Angular forms are an inherent part of a web application. Forms are used to enable the user’s login to profile, update, enter all required information, and perform numerous data entry tasks. Generally, angular has two approaches for handling the input of the user. They are reactive and template-driven.

3. Introduction to angular components 

Angular components can be termed as building blocks for any application. These components are generally connected with a template. They define different features of the user interface.  An angular app basically contains a tree of these components. These components are subsets of directives. But here, you can express only one component for a stated element in a template.

4. Angular Hello World 

Nowadays, many different applications can be developed with the help of angular. Through Angular tutorial, you can create your own Hello World App by learning all the necessary prerequisites of Angular. There are three primary prerequisites. They are Node JS, Angular Command Line Interface and Text Editor. Angular uses Node JS as a major component of its build environment.

It would be best to have Node JS installed on your personal computer to get started with angular. You should install the latest version and also need to confirm command check. For the easier development of applications, angular has created an Angular Command Line Interface(CLI). You can install  CLI by typing the proper command. A text editor should be there to run your code. The most commonly used is Visual Studio Code (VS code).

The first step is to create a folder for your application and open a new terminal and type proper command. The next step is to run the application and changing the directory.

5. Data Binding in Angular 

Data Binding in Angular JavaScript apps is the instinctive synchronization of the data between the view and model components. There are four important types of data binding in Angular. They are String Interpolation, Property Binding, Event Binding and Two-way data binding. Thus the exchange of data between model and component and vice versa is possible.

6. What is Bootstrap, and how to embed Bootstrap into Angular?

A bootstrap is an essential tool used to create and develop various web pages and web applications. It is a free project which Twitter creates. And this open source project is also hosted on GitHub. Here are the steps to integrate a normal Bootstrap into your angular project : 

1. The first step is to create an angular project with an angular command-line interface (CLI)

2. Next is to install the latest version of Bootstrap from NPM. Once it gets installed, open the angular file and next add the file paths of Bootstraps.

That’s all you need. Now you are ready to go with Bootstrap on your angular projects.

7. Introduction to Angular service and its features 

An Angular Service is used for offering various services to the angular components. Angular services are the ones that get incorporated only once in the application lifetime. They possess methods to maintain the data throughout the lifetime of an application. The primary objective is to arrange and divide business models, logic, or data and functions with various components of an angular application. They are generally executed through dependency injection.

  • Features of Angular services 

1. Angular services are typescript with the @injectible decorator.

2. Angular services are used to share a single code across different components. 

3. These are used to interact with the backend.

4. The components are singletons in angular.

5.A service can be entered as a part of a component or part of the module.

8. Angular Tutorial In Routing 

Angular Routing is a crucial part of Angular. It is used to create Single Page Applications (SPA’s). These applications are entered only once, and new content is added when required dynamically. SPQ’s provide effective service and so no need of waiting to load pages. Angular Routing facilitates navigation between multiple views. The process of defining the navigation element and the related view in the Angular is called Angular Routing.

  • How to implement Angular Dependency Injection?

Dependency injection is done by injecting a service class into a component or module class. Within the class,  injected dependency can be used anywhere.

  • Angular Interview Questions with Answers 

Angular developers have high demand because of the increasing usage of Angular. Here are some questions with answers.

1.    What are some advantages of Angular? 

Some of the advantages are Declarative UI, and Long term google support and some features provided out of the box.

2.    What are lifecycles hooks in angular?

Some component lifecycle hooks are Constructor, non-changes, ngOnlnit, etc…

Conclusion

Angular is a widely used tool nowadays because of its easy usage and convenience. So it would help if you went through Angular Tutorial for the effective usage of Angular.
