Angular 14: New Features and Updates [2022]

31 Oct 2022

It’s no secret that Angular 14 was released with several significant new features. In this article, we’ll jump right in to introduce the new Angular Elements library and template diagnostics. 

Angular 14 is out and the first release to feature the latest version of Angular, Angular Elements. It also comes with several other new features, such as improved template diagnostics and a standalone component compiler.

What’s new in Angular 14?

The latest version of Angular 14 comes with better template diagnostics. It is an extension to Angular’s compiler that helps you find errors in your templates.

Angular 14 was released in July 2022, and all the older versions have been deprecated since then.

Angular 14 uses TypeScript 2.9 as its language. It is fully backwards compatible with older versions. It improves the developer experience by removing obsolete features and adding new features like async/await support and type guards to protect against common errors by the compiler. It is similar to how TypeScript code is protected (due to static typing).

Here are the latest features of Angular 14 and how to modify your application to take advantage of them.

Standalone Components

Angular 14 introduced an exciting new feature: standalone components. Standalone components are a way to share a component between multiple projects by creating an HTML file for it instead of adding the component to your application’s main module. You can import this HTML file into any project and render it like any other view in Angular.

Standalone components are most valuable when creating reusable components that don’t depend on Angular (or any framework). They’re called “standalone”—they aren’t dependent on another library like Angular or Vue; they’re just plain old web pages! You might have seen this kind of thing before with React and Vue: there’s often a folder called “components” where all your reusable pieces live together without being part of the app itself.

In addition to making our apps more modular, standalone components also help us reuse things like authentication state management within multiple applications at work or home without having two versions floating around with different usernames & passwords stored in them. It’s taking what would generally be inside your app but moving it into its document outside so we can share those parts easily between projects without getting tangled up with all those details again down the line!

Strictly Typed Forms

One of the essential features of Angular 14 is the new strict typing for form controls. You no longer need to type annotations like input or text area. Instead, Angular will detect all controls and their types automatically.

The benefits are many:

  • Your IDE will be able to help you find errors much more quickly than before. Because it doesn’t have all possible validation rules, the compiler links your code to ensure it makes sense. 
  • If a control has a type annotation, its value must conform to that type (e.g., an email field must always have valid email syntax). It also helps eliminate typos when setting property values or methods – no more misspelling names! It even helps eliminate typos when setting values in properties or methods.
  • Type inference means you can write less code; there are fewer things to specify since you can infer the context (you only need to define what needs defining).

Angular CLI Auto-Completion

If you have already used Angular CLI, you know how to create a new project. If not, here is a quick guide:

  • Install the latest version of Node and install the latest Angular CLI globally using NPM by typing npm install -g @angular/cli@latest
  • Create an app by running ng new my-app from within your terminal
  • Navigate into your project folder cd my-app
  • Install all dependencies using npm install

Now that we have installed all necessary dependencies for our application (and even created our first one), let’s run it! To run our application in development mode, please type ng serve –open in your terminal followed by hitting Enter key or Ctrl+C to stop watching changes made to files in real-time and then hit Ctrl+C again.

Improved Template Diagnostics

Angular 2 introduced a new method for debugging template syntax errors. The ng template debug method is removed from the latest release of the framework. To ensure that you have time to migrate to the new way of debugging template syntax errors in Angular 14, we’re introducing a new diagnostic method called ng-template-error. This diagnostic will print the offending code within an error message when your app throws an error during runtime.

Streamlined Page Title Accessibility

In Angular 14, the title attribute on the element is removed. It makes it easier to use aria-label and role attributes to specify page titles. In addition, we’ve added more control over how page titles are displayed by default in Chrome and Firefox browsers. It allows us to conform with recommended best practices around accessibility for screen readers.

For example, to retrieve the title of a page in your app, you can now call a document.title on any element in Angular:

const restoredTitle = document.title;

You can also access the page title using either of these methods:

  • window. document.title
  • element.attributes[“k-page-title”]

Latest Primitives in the Angular CDK

The Angular CDK is a collection of reusable, high-quality, well-tested components for building highly interactive web applications. The CDK is a set of tools that helps you build Angular applications.

Optional Injectors in Embedded Views

An injector is a service locator that allows Angular to inject dependencies automatically into a component instance based on its type. In other words, it helps you access specific services in your application that can be used by any component inside or outside your framework.

An embedded view is simply a child of another component (called a host). It has access to the host’s injector and thus inherits all dependencies from it by default. However, what if you want to ensure that every time an injected value changes, this change will also affect the embedded views? Or maybe you need more control over when data should be requested from remote sources? In these cases, we can use optional injectors in embedded views since they are omitted by default with our components. They are only available if we ask for them specifically via their constructor function.

Angular DevTools is Available Offline and in Firefox

Angular DevTools is now available offline. If you’re a developer and an Angular user, you probably already know that the Angular team has been working on this for a long time. They hope to make DevTools more accessible to developers and ensure that it works with browsers that don’t have access to the internet.

After years of waiting, Firefox users can also use Angular DevTools!

Should you use Angular 14? What experts say

You should use Angular 14 because it is a significant release and comes with many new features. It is not too late to start using Angular 14. The developer experience is improved with Angular 14, which means you can build your application quickly and easily.

The Angular CLI is improved in Angular 14. In addition, the Angular runtime has been updated to version 7. x, which means you get new features that make it faster than ever. You should also use Angular 14 because it has many bug fixes and performance improvements, so your application will work flawlessly.

Conclusion

The Angular team has delivered another great release. It’s an excellent choice for new projects and those who want to avoid the cost of rewriting their apps. The latest version offers many improvements for developers, including improved local state management, changes to input types, and better accessibility support.
