Angular is appealing to the programmers mainly because of its concept of classes, interfaces, generics, annotations, class member variables, private/public variables, helpful compiler, and good support by familiar IDEs which makes it easier to work with Angular.
Now let’s see what are the benefits of using angular:
Single Page Application-
We can create single-page applications with Angular. Unlike other applications, where you click on a link and wait for another page to load, an Angular application gives you the experience similar to a desktop or mobile application where it feels like all the application resides on a single page.
Inside an angular application, our screen is divided into pieces called components.
Components are further made up of three parts, viz; templates, classes, and metadata. In templates, we define the HTML which gets rendered on a page.
Next are classes that contain properties and methods which are called into the template and then rendered into the page and last is metadata which tells Angular that this class and template markup are components. Inside this metadata, we give selectors which are custom HTML tags that can be used to tell our angular application were to load which component into the page.
Angular provides the feature of Server Side Rendering. Most of the web applications out there are Client-Side Rendered, which means all the necessary codes are bundled together and shipped to the client browser at once. With this approach, the user has to wait for a long time before all the necessary files are downloaded, which consists of framework code and application code. To resolve these problems, we need to render HTML code on the server when the user makes a request for a page, which is possible with server-side rendering.
Implementing server-side rendering is somehow tricky on some front-end frameworks, but not in Angular.
Progressive Web Apps-
With angular, we can create progressive web apps. A Progressive Web App (PWA) is a web app that uses modern web capabilities to deliver an app-like experience, it aims to bring native-like experience to users of all platforms and all devices. Or we can say that progressive web apps are web applications built with technologies that make them behave like native apps.
According to the standards, a progressive web app should be Reliable, Fast and Engaging. This means that they should load instantly even if the network conditions are not so good or if there’s no network at all, should be highly interactive and provide a fast user experience. i.e. smooth scrolling and animations etc. and should be engaging so the user gets an immersive experience and stays connected with the app. And we can achieve all these things with Angular.
A build optimizer is a tool that is included in the ng CLI. It makes your bundles smaller using the semantic understanding of your Angular application.
Basically, it keeps those parts of your application that are needed and mark these as pure. This improves the tree shaking process that is provided by the existing tools that finally lets you remove the additional or extra part of the application from the build.
Speed and Performance-
Progressive Web Apps: Angular uses modern web platform capabilities to deliver app-like experiences. High performance, offline, and zero-step installation.
Native: Build native mobile apps with strategies from Cordova, Ionic, or NativeScript.
Desktop: Create desktop-installed apps across Mac, Windows, and Linux using the same Angular methods you’ve learned for the web plus the ability to access native OS APIs.
Templates: Quickly create UI views with simple and powerful template syntax.
Angular CLI: Command line tools: start building fast, add components and tests, then instantly deploy.
IDEs: Get intelligent code completion, instant errors, and other feedback in popular editors and IDEs.
Full Development Story –
Testing: With Karma for unit tests, you can know if you’ve broken things every time you save. And Protractor makes your scenario tests run faster and in a stable manner.
Animation: Create high-performance, complex choreographies and animation timelines with very little code through Angular’s intuitive API.
Accessibility: Create accessible applications with ARIA-enabled components, developer guides, and built-in a11y test infrastructure.
These are only some of the core benefits of using Angular. There is much more to explore and with the upcoming versions of Angular, we might see many more features integrated with it, making it all the more powerful.
