Learning AngularJS is important to developers who want to build web applications and advance their careers in the industry of web development.

Applications

AngularJS is the popular framework of javascript used to build applications. Below are the applications of AngularJS as follows.

• Application development: It is primarily used to develop web applications. It provides multiple features while developing the applications. While using AngularJS we can build complex applications.
• Single-page applications: It is web applications, it will dynamically update the content without refreshing the page. AngularJS is ideal to build single-page applications because it provides the feature of two-way data binding.
• E-commerce websites: This website will require dynamic functionality such as sorting, searching, and filtering. AngularJS provides a powerful framework to build this website.
• Social media platforms: Social media platforms require dynamic functionality and real-time updates. AngularJS is used to build social media platforms that are responsive and fast.
• Real-time dashboards: These require constant data visualization and updates. It is used this kind of dashboard with built-in support for data visualization and data binding.
• Content management system: AngularJS is used to build the CMS that allows users to create and manage the content on a website. It provides features such as validation and forms.

AngularJS is a versatile framework, we can use it in multiple applications. We can build multiple applications using AngularJS.

Example

Below steps show how we can create a simple web application. In the below steps, we have defined an example of an AngularJS project.

• In the first step, we need to install npm and nodejs in our system. In the below example, we have already installed it in our system.

npm version

• In the second step, we are installing the angular CLI in our system. We are installing the same by executing the below command.

npm install -g @angular/cli@latest

• In this step, we create a new angular project. We are creating a new project name as an app as follows.

• After creating the project now in this step we edit the app.component.ts file as follows.

Code:

import { Component, VERSION } from '@angular/core';
@Component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
name = 'Angular ' + VERSION.full;
}

• In this step, we edit the module.ts file. The module.ts file looks as follows.

Code:

import { NgModule } from '@angular/core';
@NgModule({
imports: [
BrowserModule
],
declarations: [
AppComponent
],
bootstrap: [AppComponent]
})
export class AppModule { }

• After editing all the files now in this step we are running the application of AngularJS as follows.

Pre-requisites

To learn the AngularJS we need to knowledge on following technologies. Below are The prerequisites of the AngularJS tutorial as follows.

• HTML/CSS: AngularJS is a Java-script-based framework that is used to build web applications. We need a good understanding of HTML and CSS.
• JavaScript: AngularJS is a Java-script-based framework, so we required a good understanding of JavaScript concepts such as functions, variables, and arrays.
• JSON: It is commonly used in web applications. We should familiar with the structure and syntax of JSON.
• MVC architecture: AngularJS is following the MVC architecture pattern, that is used in the presentation layer of an application.
• Git: It is a popular version control system that is used to manage code changes in software development projects. It is used in AngularJS projects, so we required a basic understanding of git.
• Typescript: It is a superset of JavaScript which adds optional static typing and other features of this language. We required a basic understanding of this language.

Having a good understanding of this concept and technologies will help us to understand AngularJS more easily.

Target Audience

The target audience of AngularJS is varied depending on the complexity of the tutorial. However, this tutorial is aimed at web developers who are interested to build web applications. This tutorial is suitable for developers who have a basic understanding of CSS, HTML, and JavaScript. They should have the experience to write code in AngularJS.

This tutorial is also helpful for project manager and designer who works with web development teams. It will help us to understand the basics of AngularJS development and how it is used to build applications.

Conclusion
