How to Get Started With Angular Development

Angular, formerly known as Angular JS, is a JavaScript framework (though written in typescripts) for creating modern single-page web, mobile, and desktop applications. In this section, we'll delve into the world of Angular, looking at the fundamental concepts as well as the framework's nitty-gritty. In this tutorial, we'll go over the prerequisites for getting Angular up and running on our local machine, as well as how to create our first Angular project after doing so.

1. Node.js

NodeJS must be installed on our machine before we can set up Angular to run on it. In addition, we need to make sure that our development environment includes Node.js and the npm package manager.

• Node.js version 8.x or 10.x is required for Angular.
• In a terminal/console window, type node -v to check your version.
• Go to nodejs.org to download Node.js.

2. npm (Node Package Manager)

Angular apps and their Command-Line Interface rely on libraries available as npm packages for features and functionality. You'll need an npm package manager to download and install npm packages. The npm client command-line interface is included with Node.js by default and is used in this QuickStart. You need to run npm -v in a terminal/console window to see if you have the npm client installed.

3. Install the Angular CLI (Angular Command Line Interface)

Angular CLI is used to create Angular projects, generate application and library code, and perform various development tasks such as testing, bundling, and deployment. Locally or globally, the Angular CLI can be installed. However, it is frequently recommended to install it globally, so open a terminal/console window and type the following command to install Angular CLI globally using npm:

`npm install -g @angular/cli`

4. Create a workspace and a start-up application

In the context of an Angular workspace, you create apps. The files for one or more projects are stored in a workspace. A project is a collection of files that make up an app, a library, or e2e tests. To create a new workspace and an initial app project, follow these steps:

• Use the CLI command ng new to create a new application with the name my-app, as shown here:

`ng new my-app`

'ng new my-app' is a phrase that means "ng new my-app." 

• The ng new command asks for details about the features you want to include in the first app project. Accept defaults by pressing Enter/Return throughout the prompts, as this is our first application.

The Angular CLI sets up the required Angular npm packages as well as other dependencies. Depending on your internet connection, this could take a few minutes. It also creates the workspace and starter project files listed below:

• A new workspace has been created, with the root folder named my-app.
• My-app is the name of a skeleton app project (in the src subfolder)
• A full-fledged test project (in the e2e subfolder)
• Configuration files that are related

The initial app project includes a ready-to-use welcome application.

5. Serve the application

By going to the workspace folder, you can easily build and serve your app locally, as Angular includes a server (my-app). Use the CLI command ng serve with the —open option to start the server.

`cd my-app`

`ng serve --open`

The ng serve command starts the server, which monitors your files and rebuilds the app as you change them. The —open (or simply -o) option forces your browser to go to http://localhost:4200. By default, the Angular application uses port 4200. A welcome message to the Angular world appears in the browser, as shown in the image below.

6. Edit your first Angular component

Angular applications are made up of components, which are the basic building blocks. They show data on a screen, listen for user input, and act on that information. The CLI created the first Angular component for you as part of the initial app. Its name is app-root, and it is the root component. We're going to change the title property from 'my-app' to "Welcome to Angular" by clicking on ./src/app/app.component.ts. 

@Component({

  selector: 'app-root',

  templateUrl: './app.component.html',

  styleUrls: ['./app.component.css']

})

export class AppComponent {

  title = 'Welcome to Angular';

}

The browser automatically reloads with the new title. We'll need to change the CSS file to improve the appearance. To do so, open./src/app/app.component.css and apply some styling to the component.

src/app/app.component.css

content_copyh1 {

  color: 

#369;

  font-family: Arial, Helvetica, sans-serif;

  font-size: 250%;

}

Congratulations, It's starting to look a lot better! We have completed the development of our first Angular application. In the next tutorial, we'll take a closer look at the Angular file structure.

The Benefits of Angular Development for your Company

Angular is advantageous regarding both business and development. It's one of those frameworks that can work effectively with a variety of back-end languages while also combining business logic and user interfaces. Let's take a closer look at Angular's business and technical strengths and see how they are related. Many entrepreneurs expect Angular to provide a robust, cost-effective front-end component for their product that will allow them to convert more users (customers) and make money. That expectation is realized because the framework includes everything. The results from the state of JS 2018 survey on 'Why use Angular?' posed at a community of developers using Angular in their practice shows the highest satisfaction with multiple factors at the same time. These are the framework's characteristics: a clean programming style, Google support, tools, and packages.

1. Effective Cross-Platform Development

The angular framework is widely used in native-like mobile applications to create cost-effective progressive web app solutions that can run across mobile platforms. Because Angular is good at imitating real native apps, more and more companies are looking to build cross-platform solutions with it. Previously, for cross-platform development, front-end developers used the Ionic + Angular formula. The most popular formula as of right now is Angular + NativeScript. A native-like UI can be created by combining Angular with TypeScript capabilities such as services, routing, and dependency injection. A programmer can use NativeScript to access native APIs. As a result, you get a cross-platform app that works on both iOS and Android. However, if you need to create both web and mobile apps, you will need to create two separate projects.

2. High-Quality Applications

Because Angular is a complex platform that is difficult to learn, it necessitates proper developer qualifications. Numerous structural elements such as Injectors, Components, Directives, Pipes, Services, and so on may be difficult for new developers to grasp. However, they are a significant benefit to the product's success because Angular provides a comprehensive set of built-in features that allow you to create anything you can think of.

3. Increased Performance and Speed

The variety of Angular capabilities, such as template syntax, Angular CLI, routers, and so on, make programming easier and allow for faster application loading. To efficiently display gathered data in the UI, the framework is compatible with various types of back-end programming languages.

4. Accelerated Development

Because of the technical advantages provided by the framework, the Angular framework allows a developer to build Angular web apps faster and more efficiently. A list of factors assisting programmers in faster development with Angular is provided below:

• Extensive Documentation: Angular developers have worked hard to make Angular approachable and simple to learn. They provided carefully written documentation and great code examples for clarity so that a developer could easily find a way out of any problem while developing an application.
• Angular CLI: The Angular command-line interface simplifies the developer's job by providing a set of useful coding tools. Angular CLI can be extended with third-party libraries to solve unusual and complex software issues, in addition to its powerful built-in features, which we will discuss further.
• Two-Way Data Binding: Two-way data binding is a time-saving feature that automates some code generation processes. In an AngularJS Model-View-Controller architecture, if a developer changes something in the model, the view that corresponds to that model changes, and vice versa. In a nutshell, when app data is changed, the UI changes as well.

• Differential Loading: The most recent versions of Angular allow for the creation of two types of bundles: tools containing code and resources required for efficient programming. To ensure browser compatibility, one bundle is used for modern browsers that support ES2015+ and another for older browsers that support the ES5 JS version. Browsers can load less code and polyfills with differential loading, making the app more productive.
• Google Support: Google initially created Angular for its official websites and to solve problems in its internal systems. Every six months, Angular releases a new version with minor changes and a gradual, yet confident, and continuous evolution of the framework.
• Large Developer Community: Angular is widely used by developers all over the world. There has always been a strong community surrounding AngularJS since its inception. Angular specialists and developers are constantly contributing to the framework, discussing specific issues, sharing programming experience, and collaborating to solve problems.

5. Readable And Testable Code

The structural elements that make Angular code logical, consistent, and easy to follow for a front-end specialist are as follows:

• Modules: The structure of the framework, which includes modules, components, directives, pipes, and services, is associated with angular modularity. Because the framework's structure is divided into modules and components, your application is ideal for unit testing. Throughout the development process, each code unit is tested separately, allowing for meticulous quality control.
• Components: Thanks to AngularJS, applications can now be written in traditional MVC (Model-View-Controller) and MVVM (Model-View-View-Model) architectures, which improves the code's reusability. Because of the framework's flexibility, the acronym MVW (Model-View-Whatever) arose because a model-view pattern can be used to build anything. The newer versions have a component-based structure, with all elements being independent of one another. Whereas the MVC pattern divides the structure of the application into different levels, components combine the features into a single class. As a result, no matter what component a developer creates, the structure is preserved, contributing to code consistency.

6. More Lightweight Web Applications

There was a popular issue reported by the developer community in older versions of the framework about too large bundle size, which hampered the fast loading of applications. The creators of Angular address this issue in newer versions with the following enhancements:

• Lazy-Load Modules: Modules are logical elements that are used to separate business components. Large Angular apps can use lazy-load modules to display different app components based on where the user is in the app. This feature improves the performance of such apps by reducing the size of the application when it is first loaded.

• Ivy Renderer: A renderer is an engine that translates developer instructions for DOM – a web page interface that helps control page content, structure, and styles. To speed up the application, the Ivy renderer allows for smaller bundles.

7. Efficient Problem-Solving Patterns

Angular provides powerful DI (dependency injection) tools and services to address a variety of productivity issues and accelerate the development process:

• Dependency Injection: DI is a design pattern that allows you to improve an application's modularity and efficiency. It's a method of creating objects that rely on other objects. Angular's dependency injection allows it to delegate some server-side services to the client-side component.

• Angular Services: Angular components are not intended to capture and save data; rather, they are intended to represent and provide access to this data to services. Angular Services aid in the integration of business logic and app UI while also making the code cleaner. A programmer only needs to import a service once in their code and then use it wherever they need it. As a result, a specialist can work more quickly because less code is required.

8. Excellent Material Design Library

Angular Material is a library that allows you to use Material Design elements in your applications. Google's Material Design is a design system that allows for the creation of highly responsive and productive user interfaces. Programmers prefer Angular Material because once learned, it makes incorporating Angular design elements in subsequent projects easier and faster.

When Should You Choose Angular?

Use Angular to create web apps for a variety of environments, particularly:

1. Enterprise web applications

According to the Angular team, TypeScript has all the features required to develop large-scale projects. It allows you to design applications by reusing components and modules. You can also save a lot of time during the project by using a variety of libraries. TypeScript includes autocompletion, advanced refactoring, and navigation tools. Furthermore, because of the tool's architecture, you can easily reuse and maintain code.

2. Dynamic web apps

These are applications in which the content and some components are displayed based on the user who is accessing the site and the client (web or mobile) that is consuming it. Angular has a wide range of tools for SPA development because its primary purpose was to create single-page web applications. Furthermore, it is an excellent technology for websites whose content should change dynamically based on user behavior and preferences. Dependency injections ensure that if one component is changed, all other components that are dependent on it are also changed automatically.

3. Single-page Applications/Progressive Web Applications (SPA/PWA)

Angular is the solution if you need to create minimalist but highly dynamic apps. Google created Progressive Web Apps (PWAs) in 2015. The Angular team anticipates the growing popularity of PWAs and is working to make the process of creating PWAs easier. Angular 5 includes built-in PWA support. The new CLI commands included with Angular 6 make it simple for developers to convert their web apps into progressive web apps.

Angular Vs React JS

React is a UI framework that can be expanded into a full-fledged solution with the addition of additional libraries. While Angular is a more complex, but powerful tool that provides a comprehensive mobile and web development experience. Because TypeScript is a statically typed language, Angular allows you to detect errors at compile time rather than at runtime (like in JavaScript).  With two-way data binding, Angular ensures that data is always in sync at all levels, in contrast to React's one-way data binding. However, because React has a simpler learning curve, it takes much less time to get up to speed. It is a more capable mobile cross-platform framework than Angular. It also gives you a stronger direction on how the code should be organized.  Its simplicity made it easier to learn, enjoy working with, and eased the transition to component-based architecture. Angular, on the other hand, is better for complex and longer projects because it allows you to have explicit styles and detect errors at compile time.
