Angular 8 helps developers create better and more efficient website experiences—efficiencies you’ve likely already experienced in the web apps of high-profile companies. I’ve taught over 250,000 students the fundamentals of Angular and it’s a great option for building websites that resonate with users. Why do I teach Angular?

Angular is an open-source JavaScript framework developed and maintained by Google and named one of the top three web frameworks by developers in StackOverflow’s 2019 Developer Survey. Frameworks and libraries for JavaScript let developers and development teams of all experience levels build web apps that are rich in content and fast to load, crucial features to capture customers’ attention. What’s Angular: All-in-one framework 

Angular 8 is the latest version of Angular, a client-side framework for building modern JavaScript-based web applications. Rather than communicating with a server, Angular is client-side and browser-based—allowing websites to quickly and efficiently render. All user interface updates happen in the browser, instead of re-fetching HTML pages from a server.

Unlike other JavaScript frameworks and libraries like React and VueJS, Angular is an all-in-one, complete framework. Some of the tools built into Angular such as routing, state-management solution, and form validation allow the development team to rely less on third-party solutions. This allows teams to effectively build and scale web apps since packages in Angular allow developers to easily add new features. While primarily seen on web apps, Angular can also be used to build mobile apps when used in conjunction with the mobile-friendly frameworks Ionic 4 or NativeScript.

Many parts of Angular are easy for less-experienced developers to pick up including its use of HTML, CSS, and native web APIs. One piece of Angular that many developers will find challenging is its use of TypeScript rather than native JavaScript. I’ve received student feedback that some features in TypeScript take some time to learn, so keep that in mind when planning out your next Angular project, some teammates may have to learn TypeScript. 

The benefits of Angular

Angular is used across many of Google’s core apps including Google Ads and Google Trends. BMW USA and Microsoft Xbox are just a few of the many other companies using Angular in some their web apps. Generally, in cases where you need a rich user interface with only moderately static content, frameworks like Angular can shine and make building that user interface much easier. You can find more Angular uses on the Made With Angular site, which may serve as inspiration for your next Angular project.

A framework like Angular is useful for development teams because it allows them to spend their time focused on core business logic and creating a great browser-based user experience for a web app. The notion of running code in a browser is borrowed from native mobile apps, where interactions happen instantaneously, without waiting for pages to reload. It’s a great experience for your customer! 

On classic browser-based web pages, when you click a link to a separate page of that website, you’ll likely experience a wait time while that new page loads. Frameworks like Angular bring that fast native app experience to web apps, through the use of single page applications. Single Page Apps are highly reactive, mobile-like web apps, that have no page reloading wait times since the page is based on a single HTML file, while JavaScript controls everything the user sees in the browser. When a button is clicked or a new window appears on the page, there was no request made to a server, that was the JavaScript code being modified and rendered instantly.

In contrast, “traditional” dynamic pages are web pages dynamically generated on the server. Specifically, it’s the HTML code with information on the styles and scripts to attach to the page. The example of a dynamic page most people can relate to is an Amazon.com user profile. The HTML code for all the content you’d find in your Amazon profile including shipping addresses and order history was dynamically generated on the server by the server-side language, such as Node.js. Since each page is communicating with a server as it renders, the user will have to wait for those pages to load in real-time. 

Angular is a whole ecosystem

In addition to Single Page Apps, what makes Angular a stand-out option for front-end development is that it’s not just a JavaScript framework, it’s a whole ecosystem—thanks to the Angular Command Line Interface, a command line tool that simplifies the Angular development process. A command line interface is a text-based user interface (UI) used to view and manage computer files. The Angular command line interface is used directly in the command shell or indirectly through a UI tool like Angular Console. 

Created by the Angular team, the Angular command line interface helps developers get quickly started with their Angular projects by providing easy set-up of the Angular environment through generated components, routes, services, and pipes with a command. As Angular sees new updates, APIs within the command line interface will be frequently updated as well, offering developers more efficiencies. 

Depending on the needs of the developer and their team, the all-in-one ecosystem of Angular could be either an advantage or disadvantage over alternatives like React or VueJS. Built by Facebook, React is a JavaScript library that lets you drop reusable components as needed into a web app. You can also build single page applications as you do with Angular, but you’ll need to bring some extra third-party libraries to handle routing, form validation, or state management. Developers may prefer React over Angular because it’s leaner and focuses only on rendering components to the screen. Another JavaScript framework, VueJS, created by a former Google engineer, brings together the advantages of both Angular and React. It’s a framework closer to Angular (e.g. it includes routing and state management solutions), though with fewer features, yet it offers the flexibility of React. 

What’s new in Angular 8? 

Angular updates don’t typically see drastic changes. Since Angular 2’s release in 2013, the general framework syntax has remained the same. The exception was the move from Angular 1 to Angular 2. The first iteration of Angular uses a totally different syntax and has nothing in common with the Angular 2 framework foundation we now use and which all newer versions are based. Angular 1 is therefore now named “AngularJS” whereas the term “Angular” typically refers to Angular 2+.

New versions of Angular are backward compatible so you won’t have to fully rebuild your existing Angular apps. The Angular 8 update doesn’t involve any major changes, but it does include an opt-in preview of the new rendering engine, Ivy, which sets the stage for Angular 9’s release later this year. Take a look at what’s new in Angular 8:

What’s next for Angular 9?

Angular versions follow a six-month release schedule. Since Angular is open-source, changes can also always be viewed in the official Github repository and expected changes can be found in a regularly updated roadmap on Angular.io. We can expect to see Angular 9 officially released around October 2019. 

Though it’s still a bit early to know definitively what changes we can expect in the fall, thanks to Angular.io resources, we should plan for the following changes to Angular 9:

How to learn Angular

Angular and other JavaScripts frameworks are great tools for web development and you don’t need to be a senior-level engineer to work with them. A basic understanding of web development and basic Javascript comprehension are the only requirements for joining me in the Angular course
