And here comes the most awaiting news for the Angular developers’ community! Yes, Angular has indeed released its latest version called ‘Angular 14’ comprising some new features alongside solving the existing issues with the older version. Starting from version 6 to 14, Angular has come a long way in its journey. On 2nd June 2022, the Angular team at Google declared that they are coming up with the Angular v14 in June.
With the earlier success of Angular13, Angular 14 is also hoping to get success in the developers’ market. The latest Angular 14 release is considered one of the most methodical and pre-planned upgrades brought by the Angular. This update is coming up with more advanced and improved features such as typed reactive forms, directives, CLI auto-compiled, individual components, and more. Before diving into the details, it would be great to have an overview of Angular first. Let’s get started-
Overview of Angular
Angular is a framework or platform used to create single-page client apps using TypeScript and HTML. This language is written in TypeScript and contains a set of TypeScript libraries that you can import into the apps. These libraries implement the basic and optional app functionality. In Angular, the core building blocks are called Angular components systematized into NgModules. It collects relevant code into functional sets and hence, an Angular app is represented by a set of NgModules. There are majorly eight building blocks belonging to an Angular application consisting of Modules, components, templates, metadata, data binding, directives, services, and dependency injection.
Advanced Features & Updates Integrated with the Angular v14
Businesses that want to obtain AngularJS development services are eager to work with Angular v14. The current version of the Google-created TypeScript-based web application framework is already famous due to its comprised modern-edge and better features. It is said that this version is also supporting the newest TypeScript 4.7 release along with TypeScript.
Therefore, if you are also planning to go with the Angular 14, then you must have a look at its features and the latest updates on Angular 14. Go ahead-
Typed Angular Forms
Angular 14 has finally put a full stop on the top GitHub issue i.e., executing strict typing for the Angular Reactive Forms Package. It has also advanced the modern-driven approach of Angular in its modern version so that it can work flawlessly with forms. It is the most-requested feature of Angular and FormControl now also accepts a generic type representing the value type it carries previously.
Angular v14 has also comprised an automatic migration to guarantee that existing apps would not be broken at the time of upgrade. All the changes being made will be handed out swiftly and the ecosystem should not be torn apart until the API complexity is kept into consideration. These latest updates will not anyhow affect the template-based forms.
Angular modules have been classified as optional and standalone with the current update. In this, the standalone components have come up in the developer preview to be used in the procedure of app development and exploration. The primary aim of Angular is to move from the present state of affairs by developing artifacts such as pipes, components, and directives, the key focus of the TypeScript-based Angular framework.
Angular has also issued a Request for Comments (RFC) on standalone components to make the NgModules optional. This way, the modules will only become optional to balance the compatibility with the current Angular-based applications and libraries ecosystem rather than being totally vanished. It is a lot different from the previous version in which each component required a module association and each of them must be presented in the parent module’s declaration array, otherwise, there will be occurred app failure.
Angular CLI Auto-Completion
Your chosen AngularJS development company must have worked with the Angular CLI (command-line interface) in the prior version. It is helpful to increase the productivity including required commands to create the artifacts such as components, modules, and directives. Developers who have to see the official guide for the commands are no longer bound to do that. With the latest update, CLI has included this new feature allowing real-time type ahead auto-completion in the terminal.
To implement this, developers have to execute the “ng completion” command in the terminal. Type ng command > press Tab to see all the options> Enter to choose one among them. For more auto-completion options, you can use the “ng generate” command.
Improved Template Diagnostics
Better template diagnostic added in Angular v14 is helpful to save Angular developers from making basic mistakes by the compiles works same as TypeScript code. With the integration of a new private compiler option, there will be now available diagnostic tests creating warnings and information diagnostics for user templates that are not lethal.
Simplified Page Title Approachability
At the time of application design and development, the page title appears in the content preview differently. In Angular 13, this process was carried out with the new “Route.Title” in theAngular Router. In Angular v14, there is no need to add any extra imports during the title added to your page.
Tree-shakable Error Messages
With the latest Angular 14 release, there has been added a community contribution by Ramesh Thiruchelvam which is a new runtime error code. These robust error codes are helpful to find out the information about how to debug the errors or failures. It permits the build optimizer to tree-shake error messages from production bundles alongside recalling error codes.
It is recommended to go through the Angular references manuals while identifying the text to debug a production error and repeat the error in a development environment to view the full string.
“Banana in a Box” Error
It comes under the most general syntax error by developers which is to reverse the brackets and parentheses in two-way binding, they write () instead of [()]. Due to the appearance of the syntax that looks like a banana and a box, it is named ‘Banana in a box’ error as the banana should be within the box. In the Angular 13.2 release, there has been given details about the mistake and how to solve them, that too with the help of CLI and code editor.
Catch Nullish Coalescing on Non-Nullable Values
In Angular templates, prolonged diagnostics also cause errors for useless nullish coalescing operators (??). It occurs due to not ‘nullable’ input referring to its type does not include undefined or null.
There occur warnings from prolonged diagnostics at the time of ng build, ng serve, and in real-time with the Angular language service. You can configure the diagnostics in tsconfig.json where you can also identify if diagnostics should be an error, warning, or suppress.
More Built-in Improvements
As we have described that Angular v14 has provided support for existing TypeScript 4.7 and now it is aiming for ES2020 by default. It automatically permits CLI to line up smaller code without down leveling. Check out the following updates that must get recognition in Angular 14:
- Bind to secured component members straight from the template.
- Support for giving an optional injector while creating an embedded view via ViewContainerRef.createEmbeddedView and TemplateRef.createEmbeddedView.
- NgModel changes are shown in the User Interface for OnPush components, and it is ensured by the Artur Androdovych.
- CDK (from CDK menu primitives to auto-completion) and tooling improvements help in stronger development by supplying building blocks.
- CDK (Component Dev Kit) of Angular helps in creating Angular components.
- Angular CLI enhancements by adding support for combined aliases usage. It also includes ng completion, ng analytics, and ng cache.
- Angular DevTools debugging extension is now available offline, credit goes to the Keith Li and Firefox users can have the extension in the Add-ons for Mozilla.
How to Set up Angular 14?
