The team took their time to release it, as it was initially announced for September 2017, then postponed to October, and finally, the latest version of the Angular framework was released on November 1, 2017.

Let’s see what the new version of this popular front-end development framework has to offer and whether businesses should consider it in their selection of tools for building web applications.

What is Angular?

Angular is a JavaScript-based platform for developing web applications. Angular was created and is still maintained by Google, and, obviously, many Google services, such as Google Adwords and Adsense, use Angular to develop and support their user interfaces.

In 2018, Angular has been rated as the most popular front-end development framework again according to the results of the StackOverflow Survey results.
The attention to Angular is rather intense, and the arrival of the new version was long awaited.

Angular 5 is generally considered to be “faster, lighter and easy to use” as compared to the previous versions of the same framework. Generally, Angular is rather sizeable when put next to other web development frameworks, which makes it suitable for building large, enterprise-sized applications with lots of complex components.

Angular 5 is supposed to be more lightweight while keeping the advantages of its predecessor. However, this is not the only benefit of the new version, others being quite attractive and worth closer attention.

Main advantages of Angular 5 framework

The international community of Angular developers had already appreciated the improvements that they found in the new version of their preferred framework. Many of the improvements are aimed at streamlining the development, obtaining a better-quality code and reducing the number of errors.

Another aspect that is worth mentioning is the increased support of third-party component integration and the availability of a great number of modules in the initial Angular 5 package.

Build optimizer

Angular 5 has the build optimizer function enabled by default. The build optimizer removes the code that is unnecessary at runtime, thus making the bundles smaller. Less code means that the application runs faster.

Build optimization is achieved by removing the so-called Angular decorators that are used only by the compiler and have no effect at runtime. Thus, to increase the app speed and performance, the decorators are not included, therefore, the final JavaScript bundles are smaller and easier to manage.

Note that the build optimizer is available only in the Angular command line interface.

TypeScript and Improved Compilation

Although Angular belongs to JavaScript frameworks, its language is, in fact, TypeScript. It is an extension, or superset, of JavaScript. The code written in TypeScript compiles easily to standard JavaScript.

The advantage of TypeScript is in its typed nature. In JavaScript, any errors made during code creation may be discovered only at runtime, as they may be easily overlooked while writing the code. TypeScript, on the other hand, detects errors as you type, thus allowing to correct them immediately.

Since TypeScript is not the pure JavaScript most developers are used to, it takes some learning and preparation to start writing code in TypeScript. That makes the learning curve of Angular somewhat steep; however, once you learn TypeScript, you are going to love it for its effectiveness.

The compiler of Angular 5 comes with TypeScript 2.3 which makes rebuilding and compilation much faster than in the previous versions. In addition, the compiler now supports incremental compilation.

Material Design components available for server-side rendering

One of the important improvements of Angular 5 is the compatibility of Material Design components with server-side rendering. In Angular, the application pages are generated on the server and returned upon requests from the browser.

With the current updates, the framework can now render components created in Material Design on the server side. Material Design is a unique design language developed by Google with the aim of creating a universal platform for highly-technological interface design.

Angular 5 has managed to join server-side rendering with the possibility of Material Design components integration.
Please note that, although the Angular team has announced this feature, as it requires certain fine-tuning. Follow the news from the Angular developers to learn when this feature is available for use.

Progressive Web Application creation simplified

Progressive Web Applications have been “the thing” in the web development community lately. PWAs are, in fact, web applications that appear to the user like native mobile applications. The main difference between Progressive Web Apps and native apps is that the former are created to be run in a browser, while the latter are designed to work on a particular device.

To run a native application, you always need to download it to your device first. At the same time, PWA will run in a browser page without any downloading.
PWAs are as popular as they are for their flexible compatibility with various devices, responsiveness, and, what’s especially crucial for app development companies, no need to publish in app stores. App stores can be rather bureaucratic sometimes which may delay the app release.

You can find quite a lot of truly amazing PWAs already available. Check, for example, the Financial Times app that looks like a news site but behaves like a native application.

One of the Angular 5 features is enhanced possibilities of PWA creation. With Angular 5, developers have received a tool for easier creation of web applications offering native experience.

Modular development structure

Another significant advantage of Angular 5 is the inclusion of most of the required modules in the out-of-the-box configuration.
For example, you have the 
BrowserModule, HttpModule, FormsModule, and many more.

Also, you can write your own modules if you do not find the one you need in the standard Angular 5 package. Angular modules can be used in multiple web applications or exported to other modules to perform its services.

Besides, the Angular community has accumulated a wealth of reusable components that can be used in building web applications. The ready-made components are easily integratable into other Angular projects which makes development easier and quicker.

Another point worth taking note is that Angular 5 supports more manipulations with Document Object Model (DOM) within the context of server-side rendering.
Thus, Angular can now integrate more third-party components that were not built for server-side rendering.

Use of Webpack

Although Angular has been using Webpack in previous versions, too, it is worth mentioning as one of the features that make Angular convenient and effective.

Webpack is a module bundler that joins the assets that belong together and should be returned together by the server in a single JavaScript file. Webpack is a great bundling tool for large, complex applications using assets of various types. Since Angular is very well suited for creating complex web apps with lots of highly-technological components, using Webpack can considerably optimize its performance.

Why use Angular 5?

These are just the main features of the new version of Angular. Although we outlined only the highlights of the new release, we recommend looking closely at Angular in its entirety if you are selecting a reliable platform for front-end development.

Angular is the most optimal choice for projects creating feature-rich single-page web applications. Its out-of-the-box functionality is in many cases sufficient to cover the needs of front-end development, even for fairly sophisticated cases. Angular 5 is a large step forward, as it was created with the focus on making Angular development more consistent and efficient.

The list of Angular application examples is impressive. In addition to various Google services, we can find such brands as McDonald’s, MasterCard and Citibank Customer Service that use different versions of Angular for their front-end.

Moreover, if we browse the list of the best-known brands that use Angular, we can see two projects that have already switched to Angular 5 – Teradata, a database service provider, and Ngx-restangular, a service for web applications receiving data from REST APIs.

As you can see, if you opt for Angular as a tool for your project, you are going to be in a very good company. Besides, over the years of use, Angular has gathered quite a large developer community where you can find anything from peer support to a vast variety of ready-made components that you can use in building your user interfaces.

Besides, if you choose Angular as the platform for your web app development, you will have little problem putting together the developers’ team for your project. The popularity of this framework encourages many front-end developers to learn its specifics and become professionals with this tool.

On a final note, your business can benefit from using Angular 5 as a part of your development toolset. Even though it requires some “getting used to,” the result is totally worth it.
Angular is a perfect choice for building high-performance, robust, easily scalable web applications of enterprise size.
