Angular 8 Tutorial

A full-stack web framework for creating both online and mobile apps, Angular 8 is built on TypeScript. One significant benefit of Angular 8 is its support for web applications that can adapt to any screen resolution. For use on smartphones, tablets, laptops, or desktops, Angular applications are completely interoperable. For web developers, Angular 8 includes a great user interface library with reusable UI elements.

This feature enables us to develop single-page applications (SPA). SPA is a quick and responsive application. For instance, if you click a button on a single page, the action is performed dynamically within the current page rather than requiring you to load a new page from the server. Angular 8 supports server-side programming features and is an object-oriented framework built on Typescript.

What makes Angular 8 different from other versions?

Angular 8 introduces the following interesting new features:

Support for Bazel: If your application needs a number of modules and libraries, Bazel concurrent builds can help it load more quickly.
Splitting in Angular 8 and lazy loading: Data is loaded into the DOM by breaking up AppRoutingModule into smaller bundles.
Differential loading: Angular CLI builds modules when you create an application, which is automatically loaded before the data is rendered in the browser.
Web worker: It is active in the background and has no impact on a page’s functionality.
The Angular 8 CLI commands: ng-build, ng-test, and ng-run are now extended to include third-party libraries, which improves CLI workflow.
Router Backward Compatibility: The Angular router’s backward compatibility feature makes it easier for users to add code to bigger projects using lazy coding.
Users can choose whether to disclose their Angular CLI use information.

Who to begin with Angular 8?

The best platform for typescript-based programming is Angular. Create progressive web applications by utilizing Angular (PWA). Due to the robust DI (Dependency Injection) tools and services that Angular offers, the development process is accelerated. However, anyone with a working knowledge of HTML, CSS, and JavaScript may learn the Angular framework, however the list below outlines which individuals can do so.

Software developers
Software engineers
Sr/Jr Frontend developers
System Architect
UI/Ux Designers

Top Angular Developer Skills

A variety of abilities are required for Angular Developers. It is crucial to have a thorough understanding of both debugging and how Angular functions. The other areas include:

1. Typescript:

Javascript is frequently used to create web apps. The primary language used to create Angular applications is Typescript. Strong typing is supported by Typescript, a superset of Javascript. There are several benefits to using typescript instead of javascript, but the major one is to boost code refactoring and decrease problems. Your app keeps expanding and evolving by reworking typescript code.

2. Node Package Manager (NPM):

These days, a node package management (NPM) tool is required for all developers. Installing client-side web development packages makes use of NPM. It serves as the primary tool for installing Angular. Therefore, understanding how to install other NPM packages, including non-Angular ones, is crucial.

3. HTML and CSS:

The two primary technologies for web development are Hypertext Markup Language (HTML) and Cascading Style Sheets (CSS). An in-depth understanding of these two technologies is crucial for an angular developer. Because angular provides key building elements, it allows you to create web apps quickly. However, these programs should be shown in the browser using HTML and CSS.

Further, using Angular and other style libraries, you may create quick, attractive apps, but you must be aware of how things operate and what has to be done when in order to get the precise appearance you need. HTML and CSS are the most fundamental technologies and can never be modified, unlike frameworks.

4. Git/Version Control:

You have the option to experiment with your code because of Git. You may handle bugs and monitor code changes for a web application using GIT. The best feature of GIT is that it allows for easy access to previous code versions, allowing for experimentation with programs and code. The history of code modifications made by various coworkers is kept in GIT. We can simply update programs to new versions using GIT without worrying that we’ll disrupt any functionality already in place.

5. RxJS:

A library for reactive programming using observable streams is called RxJS (Reactive Extensions for JavaScript). You can carry out several standard actions, such as making HTTPS data queries, using these observable streams. Observables are created from existing asynchronous code using RxJS utility methods.

6. Angular CLI:

As we saw above, NPM is used to install the packages, thus the first package you’ll likely need to install using NPM is Angular CLI (Command Line Interface). In order to set up the new app, you may also install the angular packages one at a time. The CLI streamlines that procedure and ensures that your app will follow industry standard best practices.

Further, it may also be used to add new features, services, modules, and components to an existing program. This will ensure that you save a tonne of time on typing and that you adhere to angular code standards.

7. Javascript:

Javascript expertise is a need for angular developers in addition to their familiarity with HTML and CSS. JS handles the functionality, allowing you to add a variety of interactive elements to your program, including high-quality animation, movies, audio, and other media.

8. Responsive Design:

Developers today should be familiar with responsive web design. Because of the digital revolution, there are now a variety of devices other than laptops and desktops that use the internet, including digital watches, mobile phones, tablets, and many others. Therefore, it is essential for developers to create web apps that can adapt to all of the current device kinds.

9. Testing and Debugging:

A fundamental stage in every web development process is testing and troubleshooting. Therefore, this is a skill that every angular developer should possess. Although you write your own code as a developer, you may occasionally need to work with code created by other developers, thus being able to spot and correct problems is crucial.

10. Teamwork and commitment:

Among the several qualifications for angular developers, cooperation and dedication are also crucial. Being able to collaborate with others and having a good effect on a team is what it means to be a team player. Another crucial trait that an angular developer should possess is commitment. It’s crucial to be dedicated to the task at hand and capable of completing it no matter what.

Role of an Angular 8 developer

For the front-end of our application or website, an Angular 8 developer is responsible. As a result, the application must be developed with a performance-focused approach for both desktop and mobile responsive devices. They develop modules and components with which you will construct the application using your thorough grasp of AngularJS best practices. Using idiomatic markup and CSS animations, they improve the current design and front-end templates. However, together with the back-end programmers, they have the skills to establish a connection to APIs by utilizing industry-standard techniques. It’s crucial to comprehend the platform’s components in great detail.
