5 Top Visual Studio Code Extensions in 2020 Visual Studio by Microsoft is one of the top integrated development environments (IDEs). It enables developers to integrate their existing development suite with other applications, adding a lot of features in the process to boost your productivity. As a part of Microsoft’s efforts to open source their code, Visual Studio is available as free and open-source software. One reason behind the popularity of Visual Studio is its extensibility with the help of plugins and extensions. These add ons enhance the core functionality of the IDE enable you to make your development process more efficient and convenient. 1. Import Cost In the development process, you may often find yourself adding dependencies to your project. While modular development is a crucial part of software development today, it is a good idea to ensure that you are prudent with your imports. The Import Cost plugin for JavaScript and TypeScript allows you to be wary of any dependenc...
What is Angular?
Angular is a Javascript framework that is used by developers for building web, desktop, and mobile applications. Development of Angular applications involves usage of Typescript, which is a superset of Javascript, along with HTML, CSS etc. The code written in Typescript compiles to Javascript and is rendered in the browser. Angular is one of the most popular Javascript frameworks for building web applications. There have been three popular versions of Angular to date -- Angular 1 (also known as AngularJS), followed by Angular 2, which was succeeded by Angular 4.
AngularJS and Angular 2 are very different from each other. However, Angular 2 and Angular 4 share many similarities. Angular 4 also has backward compatibility with Angular 2, that is, the code written in Angular 2 will work fine in Angular 4.
You must be wondering that why did Angular 3 not get released? Well, there were some versioning issues with the modules internally. Hence, the Angular team decided to skip the release of version 3 of Angular and directly went on to release Angular 4. Version 5 and 6 of Angular have also released recently, and Angular 7 will be released in September or October 2018. Since Google has pledged to upgrade Angular twice every year, new versions of Angular come up frequently. However, Angular 4 is as of now the most popular among them and is widely used. All the Angular versions from 2 and above are backward compatible.
Advantages of using Angular
There are several advantages of using Angular, some of which are mentioned below.
Angular supports Single Page Applications
Single Page Applications are a type of web application that loads a single HTML page, and the page is updated dynamically according to the interaction of the user with the web app. Single Page Applications, also known as SPAs, can communicate with the back-end servers without refreshing the full webpage, for loading data in the application. SPAs provide better user experience as no one likes to wait too long for reloading of the full webpage. Angular supports the development of SPAs, and hence is worth learning!
Two-way data binding
In Angular >=2.x, the two-way data binding is implemented using the ngModel directive. The primary benefit of two-way data binding is almost automatic retrievals from (and updates to) the data store. When the data store updates, the UI also gets updated immediately.
Modularity in Angular
You can think of modularity in Angular as if the code is organized into “buckets”. These buckets are known as “modules” in Angular. The application’s code is divided into several reusable modules. A module has related components, directives, pipes, and services grouped together. These modules can be combined with one another to create an application.
Modules also offer several benefits. One of them is lazy-loading, that is, one or more application features can be loaded on demand. If properly used, lazy-loading can increase the efficiency of an application a lot.
Enterprise applications can grow very large, and hence dividing the labor across multiple teams could be challenging. With modules, the code can be kept organized and division of labor can be done properly while maintaining the code consistency.
Reduced coding
Many web developers want to write short but effective code. Angular supports MVC (Model View Controller) architecture, where the developer has to just split his/her code to fit into the MVC structure, and the rest is taken care by Angular. There is no need to write the MVC pipeline.
Declarative User Interface
Angular uses HTML for defining the user interface of an application. HTML is intuitive, declarative, and less complex than Javascript. In a declarative user interface, the presentational logic is separated from the imperative logic. We don’t need to be concerned about the program flow and the order of loading of components on the webpage. We can simply define the layout of the page, make it clear where the data is being bound, and what it is being bound to. Angular will take care of the rest.
Easy integration
Angular integration is pre-built into several frameworks, for example, Ionic, Telerik’s Kendo UI, Wijmo, etc. Hence, integration of third-party features is easy with Angular. So, if you want to add some high-quality user interface components, you can easily do so by using any of the above-mentioned frameworks!
Cross-Platform
Angular can be used to make any of the following types of applications:
Web applications: Angular can be used for web development. Also, from Angular 5 onwards, progressive web applications can also be developed. Such applications have high performance and can work offline as well.
Native mobile applications: Native mobile applications can be built using Angular.
Desktop applications: Angular can be used to create desktop-installed applications for Mac, Windows, and Linux.
