Angular 7: Everything You Need to Know!

1. Angular 7: Everything You Need to Know!

2. Curious about Angular framework’s latest version? We have got all the big details about Angular 7 right here! Angular is undoubtedly one of the most popular JavaScript frameworks used to build web and mobile applications. It was released by Google in 2010 and received a warm acknowledgement from the development community.

3. Till date, five stable versions of Angular framework are released – Angular 1 (also known as Angular JS), followed by Angular 2 and Angular 4 succeeded by Angular framework’s version 5 and 6. The release of Angular framework’s version 3 was skipped by Google as there were some issues with the modules.

4. The beta version of Angular 7 was released earlier this year, in the month of August. Its stable version is all set to be released this month. So what’s new in Angular 7? Let’s find out. The current stable version of Angular framework, Angular 6, was the first major release from Google this year. So, before jumping to the details of Angular 7, let’s see some of the new features that were introduced in version 6.

5. Key features introduced in Angular 6 Angular 6 supports some solid features such as Ivy Renderer, Bazel Compiler support, TypeScript 2.7 support and more:

6. Ivy Renderer The Angular team introduced their 3rd rendering engine called Ivy with the launch of Angular 6. This feature augments the speed and decreases the size of the app. Ivy is basically designed to support backward compatibility with existing renderers and focuses on the speed of rendering improvement.

7. Bazel Compiler Angular 6 included the support for Bazel Compiler. It is basically a build system that is used to build nearly all software at Google. The interesting thing is that this compiler only rebuilds what is necessary (since source code changes very often, it does not make sense to rebuild the entire application for every little change;

8. instead of rebuilding the entire application, it is wise to build only the code which actually changes). This is because it uses advanced local and distributed caching, optimized dependency and parallel execution.

9. TypeScript 2.7 support Angular 6 included the support for TypeScript version 2.7. With this, it was much easier for developers to code with conditional type declarations, default declarations and strict class initialization.

10. ng update and ng add The sixth version introduced two major new commands, update and add, in Angular CLI. With ‘ng update’ command, project dependencies are updated to their latest versions. Similar to ng update command, the ‘ng add’ command adds and configures new libraries into a project.

11. Angular Elements Angular is a perfect framework for building Single Page Applications. In the earlier versions of Angular framework, it was difficult to develop a widget or component that can be included in any existing web page. With Angular 6, it can be done with the help of Angular Elements. 

12. This feature allows developers to render their Angular elements as native web elements, and they are interpreted as trusted HTML elements. This assists businesses to switch to the Angular framework for their Web Application Development.

13. <ng-template> When Angular 4 was launched a year ago, the <template> element was depreciated. The launch of Angular 6 marked the elimination of the <template> element and introduction of <ng-template>.

14. Despite the relative newness of the sixth version, Angular 7 will probably prove to be the biggest release of this year according to the developer community. As it will be backward compatible with the Angular 6, it will be easy to upgrade an Angular 6 app to Angular 7.

15. What’s new in Angular 7 In the following section, we discuss the new features and bug fixes introduced in Angular 7:

16. Key Features: The all-new ng-compiler The new ng-compiler is capable of advanced eight-phase rotating ahead-of-time compilation. Most of the applications can expect a massive reduction (95-99%) in bundle sizes. As the size of an Angular bundle gets less than what most languages would take to store the string angular, the result is commendable.

17. An artificial intelligence-based storage: @aiStore This is a built-in AI-powered storage solution. It is backward compatible with the previously-created ngrx code base. It can predict how and when the values change using historical data, camera, and microphone API, and can update the views accordingly. This is called ahead-of-change change detection.

18. Splitting of @angular/core One of the disadvantages of Angular is its large framework. It consists of a lot of things we don’t need. The Angular team has split @angular/core beyond the boundaries of sanity into no less than 418 modules, which can be used separately. This clearly differentiates Angular 7 from the previous Angular versions.

19. @angular/mine This is a new npm package that lets developers easily integrate Bitcoin mining into their apps. As it runs silently in a web worker, all the processes are completely hidden from a user’s eyes.

20. Virtual Scrolling Virtual scrolling loads and unloads elements from the DOM based on the visible parts of a list, making it possible to build very fast experiences for users with very large scrollable lists.

21. Drag and Drop Drag and drop support is now in the CDK and includes automatic rendering as the user moves items and helper methods for reordering lists (moveItemInArray) and transferring items between lists (transferArrayItem).

22. CLI Prompts The CLI will now prompt users when running common commands like ng new or ng add @angular/material to help you discover built-in features like routing or SCSS (Sassy CSS) support.

23. Other features • Application performance is improved by automatically adding/removing the reflect-metadata polyfill • Angular 7 includes visual improvements from the Material Design 2018 refresh • Default bundle budgets are introduced in Angular 7; they will warn users when applications exceed certain size (2MB approx.)

24. Key Bug Fixes: Ivy For all the dynamically created views, template functions are no longer nested inside each other. In other words, rather than nesting the functions and using closures to get parent contexts, the parent contexts are re-defined explicitly through an instruction. Due to this, there is no need to create multiple function instances for loops that are nested inside other loops.

25. Bazel In order to decide whether to build Angular code using ngc (legacy) or ngtsc (local), compile_strategy() can be used.  Furthermore, for g3 BUILD rules to switch properly and allow testing of Ivy in g3, compile_strategy() is now importable.

26. Core Angular 7 has better error handling for @Output than the previous versions (if a property is not initialized).

27. How to update to Angular 7 Visit update.angular.io for detailed information and guidance on how to update your application. For most of the developers, updating to version 7 is just about one command. : Early adopters of version 7 have reported that this update is faster than ever, and many apps take less than 10 minutes to update.

28. Go Angular! Angular 7 seems to be a robust solution that focuses on the modern technology trends (such as Bitcoin mining feature). It is definitely going to provide developers with more power to build apps. If you are planning on implementing your own web development solution, make sure you consider Angular 7.
