Basic Overview of Angular Framework
The first question that hits the mind of the developer is “What is Angular?” The best approach to creating web applications is with Angular.
To understand the Angular framework in detail, you must have basic knowledge on:
- HTML, CSS, JavaScript
- MVC Framework
- Document Object Model (DOM)
- TypeScript Basics
Moreover, Angular is a framework for building single-page applications (SPAs). Developers working in the best AngularJS development company typically use Angular Command Line Interface (CLI) to create projects, generate application and library code, and perform various ongoing development tasks such as testing, bundling, and deployment.
NPM packages play an essential role in Angular applications and it contains multiple features and functions. To download and install npm packages, you need a node package manager (npm).
Why Should You Learn Angular?
Angular is a top-rated framework that helps developers to design and build web and mobile apps for all business needs. Moreover, it is an excellent platform for building large-scale, robust, easy-to-serve web applications.
Let's highlight some of the best reasons for using Angular for your next web app development.
- Safety: Angular is a reasonably trustworthy platform because Google supports it
- Minimized Development Time: Angular framework is dependent on the JavaScript virtual machine. It helps developers to transform templates into code quickly; thereby, Angular's application load time is also quicker.
- Unit-Test Friendly: With its two-way data binding of modules and components, Angular helps developers deal with code consistency and is easy to understand for unit testing. Every code unit is independently tested across the entire app-building process, providing in-depth quality control.
- Cross-platform: Angular-based PWAs can run on various platforms, and the framework is widely used in the native mobile app. The previous versions of the Angular framework included cross-platform capabilities like Ionic with Angular. Nowadays, the framework work fluently even with NativeScript.
- Complex Learning Curve: Angular has a complex learning curve as it typically includes essential aspects of the framework like RxJS (a reactive library for asynchronous development) and Typescript (that is responsible for enhancing the code maintainability and code support capabilities), not just basic JavaScript.
- Community: Angular has a great community and ecosystem by including plenty of content on the framework, like guides and videos and many useful third-party tools.
Don’t Get Confused with Angular and AngularJS!!
The first version of Angular is AngularJS. Angular Version 2+ is referred to as Angular; rather than AngularJS. The Google community did detailed research and rewritten the entire Angular application to make AngularJS a separate framework.
What are the Advantages of Angular Framework?
Supported by Google
One of the biggest advantages that have come up with the Angular framework is the Long-Term Support (LTS). Google offers long-term support for Angular, which helps you to deal with Google’s plan to keep using the framework and expand the Angular ecosystem.
Do you know that Google employs Angular and it is solely responsible for improving the performance of web applications? Your web application scaling is maintained properly with the help of LTS.
TypeScript-Supported Framework
TypeScript is the language that plays a vital role in Angular application development. TypeScript is merely a superscript for JavaScript, and it promotes the highest level of code quality, increasing the security of the web application.
Its active support of TypeScript helps Angular developers easily detect and eliminate mistakes early on while writing the code or performing maintenance operations.
Browsers will not execute TypeScript directly. First, the Typescript code must be “transpiled” into JavaScript with the help of tsc compiler, which requires some configuration.
Declarative UI
With the help of HTML, the user interface (UI) of the Angular application is built. Compared to the JavaScript programming language, HTML is a simpler language. Angular is also a declarative and easy-to-use language that exclusively supports directives such as ng-app, ng-model, etc.
POJO (Plain Old Java Object)
POJO approach is included in the Angular framework. The developers are not involved in using Angular’s getters and setters method.
Once you include POJO, it becomes easy for your to perform object manipulation using all of JavaScript’s standard functionalities. Not only this, it becomes easy for them to remove or add properties from the things that make your application more robust.
SPA and PWA
One of the most cost-effective methods for website development to make it behave like a mobile app is a Progressive Web App (PWA). It just reduces the network requirements and, most importantly, improves the web app performance.
You may develop Single-page web applications (SPA) when the developers need to utilize the server-side rendering capabilities of Angular. In addition, developers can quickly load the home page, and that generally help to improve website performance on mobile and low-powered devices.
Simplified MVC Pattern
The angular framework renders MVVM (Model-View-ViewModel) architecture and not an MVC (Model-View-Controller). The MVVM model allows you to perform two-way data binding between View and ViewModel.
In addition, the framework allows you to deal with the automatic propagation that typically changes within ViewModel’s state to the view. ViewModel utilizes the observer model that helps you to make changes to the ViewModel model to model.
Modular Structure
The Angular source code is divided into different core elements like Angular components, directives, pipes, and services. Modules are considered to be the heart of the Angular framework. The smooth framing of application features is something that developers can do with ease.
Modules play a vital role in lazy loading. In simple words, once you include modules, the loading features of the application in the background or on-demand turn out to be faster.
With the help of Angular, the complex app development process is made easier while dividing work and ensuring organized code. When you have the expertise, it becomes easy for you to include modules in the application..And in such a case, modularization is one such thing that might enhance developer efficiency in certain situations.
