History & Versions of Angular

Angular has undergone several major updates, each bringing significant improvements and new features.

AngularJS (Angular 1. x)

Angular's journey began with AngularJS, also known as Angular 1. x, which was released in 2010. It revolutionized web development by introducing a Model-View-Controller (MVC) architecture for building dynamic and interactive user interfaces. AngularJS utilized HTML as a declarative language and extended it with directives, enabling developers to build custom elements and behaviors.

Angular 2

In 2016, Angular 2 marked a significant departure from AngularJS, rewriting the entire framework to address its limitations. Angular 2 was not backward compatible with AngularJS, which led to some initial challenges for developers. However, it introduced a more efficient and performant framework built on modern principles.

Angular 4, 5, and 6

To streamline the versioning process and avoid confusion, Angular moved to a semantic versioning system. In March 2017, Angular 4 was released, followed by Angular 5 later that year and Angular 6 in 2018. These updates focused on improving the framework's speed, reducing package sizes, and introducing new features.

Angular 7 and 8

Angular 7, released in October 2018, and Angular 8, released in May 2019, continued the trend of enhancing performance, reducing the application size, and providing a better developer experience.

Angular 9 and 10

Angular 9, launched in February 2020, introduced significant improvements under the hood while maintaining backward compatibility. It also brought updates to the Angular Material UI component library.

Angular 11, 12, and Beyond

Angular 11, released in November 2020, continued the focus on improving performance and developer experience. Subsequent versions, including Angular 12 and beyond, have continued to build upon these foundations, introducing new features, bug fixes, and optimizations.

What is Angular?

For creating client-side web applications, Angular is an open-source framework built on Typescript. Let’s first quickly understand JavaScript since it is a superset of Typescript. JavaScript is a client-side scripting language that may be used to create or program how web pages should respond to specific events. JavaScript is typically used for slide shows, interface interactions, and other interactive elements. The rapid evolution of JavaScript has led to its adoption in game creation, server-side programming (like Node.js), and other areas. In both India and the US, demand for Angular is higher than that of all other Web Developer Training Programmes.

Dynamic content is a key component of web development, and JavaScript deals with it. Dynamic content is content that changes frequently and is tailored to individual users. By examining the device accessing the website, JavaScript, for instance, can decide whether or not to render the website’s mobile version.

This inspired web designers to start building their own unique JavaScript libraries to cut down on code and simplify the implementation of complex functionality. The traversal and manipulation of HTML documents, event management, animation, and Ajax are all made much easier with the help of the quick, compact, and feature-rich JavaScript library known as jQuery. Because it was simple to use and incredibly strong, jQuery quickly grew to become the most used one.

By industry-standard practices for web development, Angular is a client-side JavaScript framework that was created to assist developers in creating SPAs (Single Page Applications). The risk of creating “spaghetti code” is significantly decreased by offering a structured environment for developing SPAs. What is SPA, then, must be on your mind.

Single-Page Applications (SPAs)

Single-Page Applications (SPAs) have emerged as a game-changer in modern web development, transforming the way users interact with websites and web applications. Unlike traditional multi-page websites, SPAs load, and update content dynamically on a single web page, providing a fluid and seamless user experience.

Understanding Single-Page Applications (SPAs)

A Single-Page Application is a web application or website that fits entirely on a single web page. When users interact with the application, it dynamically loads and updates content without the need for full-page reloads. SPAs rely heavily on JavaScript frameworks like Angular, React, or Vue.js to handle the dynamic rendering and provide a smooth user experience.

Key Features of Single-Page Applications

Asynchronous Data Loading: SPAs use AJAX (Asynchronous JavaScript and XML) to fetch data from the server without reloading the entire page. This enables real-time updates and a more responsive interface.

Dynamic Content Rendering: SPAs leverage client-side rendering to dynamically update content based on user interactions, reducing server loads and enhancing speed.

Smooth Navigation: SPAs use client-side routing to manage navigation without requiring server requests. This results in faster transitions between different sections of the application.Improved User Experience: By eliminating page reloads, SPAs create a seamless and interactive user experience similar to that of a desktop application.

Data Binding in Angular

Data Binding is a foundational concept in Angular that enables developers to establish seamless communication between the application’s data model and its user interface (UI). By implementing data binding, developers can ensure that changes in data are automatically reflected in the UI and vice versa, simplifying the development process and creating more interactive and responsive web applications. In this article, we will explore the different types of data binding in Angular, their application, and how they contribute to building dynamic user interfaces.

Understanding Data Binding in Angular

Data binding is the mechanism that establishes a connection between the application's data model (usually the component properties) and the UI elements, such as HTML elements or Angular templates. When the data model changes, the UI is automatically updated, providing a real-time view of the data to the user. Angular supports various types of data binding, each serving different use cases.

Types of Data Binding in Angular

Interpolation (One-Way Binding)

Interpolation, denoted by double curly braces {{ }}, allows developers to bind data from the component to the template. For example, <h1>{{ title }}</h1>. Any changes to the title property in the component will be reflected in the template automatically.

Property Binding (One-Way Binding)

Property binding uses square brackets [ ] to bind component properties to HTML element properties. For example, <img [src]=”imageUrl”>. When the imageUrl property in the component changes, the src attribute of the img element updates accordingly.

Event Binding (One-Way Binding)

Event binding, denoted by parentheses (), allows developers to bind UI events (e.g., clicks, keypress) to component methods. For example, <button (click)=”onButtonClick()”>Click Me</button>. When the button is clicked, the onButtonClick() method in the component is executed.

Two-Way Binding

Two-Way Binding combines property binding and event binding into a single expression using the [( )] syntax. It allows data to flow in both directions between the component and the template. For example, <input [(ngModel)]=”username”>. Any changes to the username property in the component or the input field will automatically update each other.

Angular Routing

Angular Routing is a crucial feature that empowers developers to create seamless navigation within Single-Page Applications (SPAs). As the user interacts with an Angular application, routing allows for the dynamic loading and display of different components without the need to refresh the entire page. In this article, we will explore the fundamentals of Angular Routing, how to set it up, its key components, and how it facilitates the creation of responsive and interactive web applications.

Understanding Angular Routing

Angular Routing is a mechanism that enables navigation between different views or components within a SPA. It allows developers to define routes for various sections of the application, associating each route with a specific component. When a user clicks on a link or interacts with a UI element that triggers a route change, Angular seamlessly loads and displays the corresponding component without reloading the entire page.

Setting Up Angular Routing

To implement routing in an Angular application, follow these steps:

Install Angular Router: Angular Router comes pre-installed with the Angular CLI. If you are starting a new project, you can use the following command to generate a new application with routing enabled: ng new my-app –routing.

Define Routes: In the app-routing.module.ts file, define the routes using the RouterModule.forRoot() method. Each route is an object with a path (URL segment) and component (associated component) property. Add Router Outlet: In the root component’s template (usually app.component.html), add the <router-outlet></router-outlet> tag. This placeholder will be replaced with the content of the active route’s component.

Why Angular?
