A little history of Angular
The Angular framework was released in May 2016 by Google. Initially, it was supposed to be a successor to the previously popular AngularJS framework from 2009, but due to the lack of backward compatibility, it eventually became a separate platform. Right from the start, it received a lot of positive feedback from the developer community. Its main advantage is its speed, so a significant number of web developers started using Angular in their projects.
Before Angular became popular, the web markup language was static, which meant that users could not interact with interfaces on HTML pages. Of course, there were several ways to create dynamic Single Page Applications (SPAs), but they were complicated and very time consuming. It wasn’t until the Angular architecture that programming efforts were reduced.
The framework allows simple transformation of static HTML documents into dynamic interfaces.
Why should I use Angular?
The versatility of Angular and its architecture make it very popular among developers in recent years, and its knowledge is desired by employers. However, popularity and support by a large company are not the only advantages of Angular. What else is worth paying attention to?
The Angular environment is pre-configured, which greatly speeds up programming and makes testing easier. The default configuration makes it possible to start working immediately after launching the application.
The Angular CLI command-line tool lets you quickly create and add individual components and run tests. This makes deploying an application built on Angular almost instantaneous.
Popular applications using Angular
Every month there are more and more new applications built using this framework, including those built by the largest technology companies in the world:
What does the Angular application architecture look like?
Angular’s component-based architecture is its main differentiator from other frameworks. All components are organized into NgModules, which define the entire Angular platform. Each Angular application consists of a core module for initial loading and multiple function modules.
Individual components can be thought of as small UI elements, such as an application section. A component in Angular consists of a class file, a template (HTML template) and a css/scss file. In Angular, there is a strict hierarchy of components that are limited by their functionality. Examples of components introduced in the latest version of Angular 9 are Google Maps and YouTube Player.
All components can be used multiple times, in different places of the application. They are completely independent of each other, which means that they can also be independently tested. Thanks to the component-based approach, applications developed with Angular are characterized by extremely high performance and “testability”.
Angular is a modular framework. Each module consists of individual building blocks, such as components, directives, pipelines, and services, which are related to the application and together determine its functionality. Angular provides developers with many built-in, pre-built modules.
Modules, components, and services are component classes that use decorators that, using metadata, send information to Angular about how to use them.
Component class metadata is responsible for linking each class to a template that defines the application view. The template is responsible for linking the HTML code to Angular’s directives and link tags. These two elements allow you to modify individual pieces of HTML code before rendering them for display.
Angular template directives are responsible for all the logic of the framework. The tags, on the other hand, link the data of the application under construction to the DOM. Thus, the Angular platform effectively prevents DOM manipulations and affects the ease of application testing.
Angular is a technology that is highly valued in the programming environment and has gathered around it a large community. In particular, Angular is appreciated by front-end developers. Thanks to it, they can create an impressive visual layer of web applications. This framework will prove itself primarily in the implementation of large and complex projects.
