What’s New in Angular 14?

Angular 14 Important Features and Examples The TypeScript-based web application framework, Angular 14, was released on June 2, 2022. Compared to earlier iterations of Angular 13, Angular 14 is regarded as Angular's systematic, pre-planned improvement.

With new Angular 14 capabilities like stand-alone components, which do away with the need for ng modules, web app development has become simple and rapid.

Just a quick summary of Angular 14's new features. We have developed comprehensive information and examples to make dealing with Angular development simple for developers.

Angular 14 Features As we all are aware of what is Angular, it’s time to explore the Angular 14 features introduced officially by the Angular development community. ● ● ● ● ● ● ● ●

Standalone Components

The components are referred to as Angular 14 standalone components because they are independent of any other components.

The ngModules were a prerequisite for all Angular 13 and earlier version components.

Therefore, you must import all such items in the module file if you want to utilize or include any more modules, pipes, services, or even directories in the component.

However, the situation is fundamentally different in Angular 14. How? Let's look at a straightforward example of building a solo Angular 14 component. First, we'll use the command to independently construct one component, "HomeComponent".

Standalone Components

ng generate component HomeComponent — standalone You'll find "standalone: true" in the HomeComponent file, indicating that this is the application's standalone component Therefore, you can quickly import any content into this component, including services, directories, and pipes.

However, developers can quickly import individual services or directories into a given component with Angular 14. This standalone component has the disadvantage of having an unstable API, which increases the risk of possible changes.

Typed Angular Forms

As we all know, Template-Driven and Reactive Forms are the norms in Angular. So far, in the reactive forms of Angular 13. Imagine you've defined a type of reactive form and wish to change the value of that form's field. It's straightforward, however, because Angular exclusively uses the TypeScript programming language, it's not a smart practice.

Typed Angular Forms were introduced in Angular 14 to simplify things for developers. It employs rigorously typing and completely avoids the Angular Reactive Forms Package's implementation of the strict type.

The Typed forms feature in Angular 14 aims to provide type safety for all values contained in form controls, groups, and arrays. In particular for deeply nested complex scenarios, it aids Angular developers in enabling safer forms.

The great thing about Angular 14 is that if developers don't want to use Typed Forms, they may use "UnTyped FormGroup."

Streamlined Page Title Accessibility It was difficult for developers to modify the titles of various pages in the application in Angular 13 and the preceding version. With the help of the "title" property in Angular 14, developers can add the title to each page.

Extended Developer Diagnostics This Angular 14 functionality is a great benefit for Angular developers. For instance, it won't throw an error if there is a mistake in any file other than the template file. Sounds amazing?

A framework that can be expanded by the new extended diagnostics offers you more information about the errors in your templates and makes recommendations for how to fix them. Diagnostics provide accurate, actionable advice for your templates at build time, discovering errors before run time.

Banana in a box” Error

When dealing with two-way data binding features, Angular developers working for AngularJS development businesses often employ brackets and parentheses.

You’ll get a syntax error by writing ([]) instead of [()]. As () looks like a banana and [] looks like a box, it is represented as “banana in a box”.

Even though this mistake uses proper syntax, our CLI can tell that this is rarely how developers intend it. Because of this, we added through messaging on this error and instructions on how to fix it to the CLI and your code editor in the v13.2 release.

Catch nullish coalescing on non-nullable values In most cases, enhanced diagnostics raise issues for (??) - nullish coalescing operators while developers are working with Angular templates.

This Angular 14 feature appears when the particular input is "not nullable. When its type is undefined or does not include null, to put it simply.

Additionally, the enhanced diagnostic features display warnings for ng build, ng serve, and the Angular Language Service in real time. The main file where developers may deal with fundamental configurations and determine whether diagnostics should be a warning, error, or suppressed is tsconfig.json.

Nullish Coalescing on Non-Nullable Values

Angular CLI Enhancements With the release of Angular 14, standardized CLI argument parsing has given developers more uniformity throughout the Angular CLI. Additionally, developers are free to add the -lower-skewer-case format to each flag.

With the release of Angular 14, a feature was introduced that removed support for deprecated camel case arguments and provided support for the use of combined aliases. ●

ng analytics

ng cache

Angular DevTools is Available Offline and in Firefox Keith Li made a community contribution that enabled offline use of the Angular DevTools debugging extension. Users of Firefox can locate the extension under the Mozilla Add-ons section.

How To Install Angular 14?

The first step is to install Angular 14 using npm. Just execute the following command in the CLI. D: \> npm install - - global @angular/cli@next

How to Upgrade to Angular 14?

To upgrade your Angular application to Angular v14, see the guidelines on its official website – https://update.angular.io/

Additional Summary ●

With this release, the public Angular 14 roadmap has been updated to reflect the state of ongoing and upcoming team initiatives and explorations.

●

Versions of TypeScript before to 4.6.0 are no longer supported.

●

FormControl and FormGroup, reactive form types, now contain generic type parameters and infer stricter types. Existing usages will be migrated to new Untyped-prefixed aliases while maintaining the current behaviour.

●

Be sure to use Node 14.15.0 or a later version.

Conclusion

As we've seen, the developer-friendly features of Angular 14 range from typed forms and Angular 14 standalone components to new primitives in the Angular CDK, making it more powerful than ever (component dev kit) We read through the in-depth descriptions of each feature, each of which was illustrated with examples, to learn more about the Angular 14 features.

With the newest Angular14 version, I hope this will assist you with your current or next project.
