Angular is one of the most widely used and popular front-end frameworks. As Angular technology becomes more popular, the market for hiring Angular developers is becoming increasingly competitive. More countries are expanding their Angular development teams as the demand for experienced and professional Angular programmers increases.

This platform can be used to build desktop and mobile applications. Many cutting-edge companies use Angular to build modern web applications. Angular certifications are the best way to secure a job in this field with a high salary.

If you’re still not familiar with this technology, you can learn Angular by following our complete Angular tutorial.

What is Angular?

Angular is a JavaScript Framework written in TypeScript, maintained by Google. It allows users to easily develop and test large apps. Javascript has been surpassed by Angular for the development of single-page apps that demand modularity, testability, and developer efficiency. This Angular Tutorial will teach you about Angular Architecture and its advantages.

History & Versions

Angular was rewritten from the ground up of AngularJS by Google.

1. Angular 2

Angular 2 was announced in October 2014. Developers were divided by the dramatic changes in version 2.0. According to the Angular Team, Angular 2 was promoted to Developer Preview from Alpha on April 30, 2015 Angular 2 reached Beta status in December 2015 and released its first release candidate in May 2016.

2. Angular 4

On the 13th of December 2016, Angular 4 was released. 3 was skipped in order to avoid confusion due to a mismatch between the version numbers for the router package which was already published at v3.3.0. This release introduced HttpClient – a more powerful, simpler, and easier-to-use HTTP Requests library – as well as the router life cycle events of Guards and Resolvers.

3. Angular 5

Angular 5 was released on 1 November 2017. Angular 5 features include support for progressive web applications, a build optimizer, and Material Design enhancements.

4. Angular 6

Angular 6 was released on May 4, 2018 This version is a major release that focuses on making future Angular Development easier. It includes: ng update and ng add. Angular Elements and Angular Material Components + CDK, Angular Material Components Starter Components. CLI Workspaces. Library Support. Tree Shakable providers. Animations Performance Improvements. RxJS v6.

 

5. Angular 7

Angular 7 was released on October 18th, 2018. Updates include Application Performance, Angular Materials & CDKs, Virtual Scrolling, and Improved Accessibility for Selects. Content Projection using web standards is now supported for Custom Elements. Typescript 3.1 and RxJS 6.3 are also updated, as well as Node 10 and Typescript 3.1 dependency updates.

6. Angular 8

Angular 8 was released on May 28th, 2019. Angular 8 includes dynamic imports, lazy routes, Web Workers, TypeScript 3.4, and an opt-in Angular Ivy preview. The opt-in for Angular IIvy includes:

• Runtime code generation that’s easier to debug and read
• Rebuild time is faster
• Increased payload size
• Checking template types has been improved
• Backward compatibility

7. Angular 9

Angular 9 will be released on the 6th of February 2020. Version 9 uses the Ivy runtime and compiler by default. TypeScript 3.6 or 3.7 can be supported by Angular. Ivy’s compiler and runtime provide many benefits in addition to hundreds of bug fixes.

• Smaller bundle sizes
• Tests are faster
• Better debugging
• Improvements to CSS class and style binding
• Type checking improved
• Build errors are reduced
• The build times have improved and AOT has now been enabled as standard.
• Improved Internationalization

• Support for IE11 has been deprecated
• Each release should be backward-compatible with the previous version.
• The Angular team has promised to update the framework at least twice a year.

Angular Tutorial

In this tutorial, we will cover the basics of Angular and provide you with a step-by-step guide to building your first Angular application.

1. Setting up Angular

The first step to building an Angular application is to set up your development environment. To do this, you will need to have Node.js and npm (Node Package Manager) installed on your computer. Once you have these installed, you can use the following command to install the Angular CLI (Command Line Interface):

npm install -g @angular/cli

2. Creating a New Angular Application

Once you have installed the Angular CLI, you can use it to create a new Angular application. To do this, navigate to the directory where you want to create your application and run the following command:

ng new my-app

This command will create a new Angular application in a directory named my-app.

3. Running the Angular Application

To run the Angular application, navigate to the directory where you created the application and run the following command:

cd my-app
ng serve

This command will start a development server and open your Angular application in a web browser. You can now start developing your Angular application.

4. Components

Components are the building blocks of an Angular application. Each component is responsible for a specific part of the application’s user interface. To create a new component, use the following command:

ng generate component my-component

This command will create a new component named my-component.

5. Templates

Templates are used to define the structure and layout of an Angular component. Templates are written in HTML and can include Angular-specific syntax. To create a template for a component, add a file named my-component.component.html to the component’s directory and add the HTML code for the template.

6. Styles

Styles are used to defining the appearance of an Angular component. Styles can be written in CSS or any other stylesheet language. To add styles to a component, add a file named my-component.component.css to the component’s directory and add the CSS code for the styles.

7. Services

Services are used to share data and functionality between components in an Angular application. Services are created as classes and can be injected into components using dependency injection. To create a new service, use the following command:

ng generate service my-service

This command will create a new service named my-service.

8. Routing

Routing is used to navigate between different views in an Angular application. To set up routing in an Angular application, add a file named app-routing.module.ts to the app directory and add the following code:

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { MyComponent } from './my-component/my-component.component';

const routes: Routes = [
{ path: '', component: MyComponent },
];

@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }

This code sets up a route for the root path of the application that will display the MyComponent component.

9. Building and Deploying the Angular Application

To build an Angular application for production, use the following command:

ng build --prod

This command will create a production-ready build of the Angular application in the dist directory. To deploy the Angular application, you can use a hosting service such as Firebase, AWS, or Azure.

That’s it! This is just a simple example of what you can do with Angular. There’s a lot more to learn, such as how to create services, use routing, and work with forms. But this should give you a good starting point for building your own Angular applications.
