    What’s New in Angular 15 And Why Should You Upgrade?

    Every new upgrade to AngularJS comes with major changes and improvements in the application. The latest version of Angular offers many significant advantages over the older versions, which is why you should upgrade now rather than later.

    Here are some of the new features you’ll find in Angular 15:

    1) Single File Components:

    This is a much-awaited feature, as this will make it easier for designers to now share regular styling and individual components, including multiple files between different apps.

    The latest Angular version supports the creation of component files, unlike the previous version where you could only create component templates in a file.

    2) Modified API System:

    AngularJS 15 is the first version ever to provide built-in support for the modules. The new API system of Angular v15 has the feature to use the modules without leaving the app. This is a much-needed and welcoming change for developers, for whom using packages is now easier than ever before.

    With the new API system in AngularJS v15, interacting with APIs when developing an app would be much simpler since you no longer need to create code for everything.

    Whether you are looking to build data models or gain access to authentication systems or work with JSON data from an API\, you can easily use existing libraries. As this requires you to write less code, the performance of your app will increase

    3) Image Directive:

    The new directive will allow developers to insert images into the DOM as well as specify the exact dimensions and positions of inserted images on the screen.

    The Image Directive is a type of HTML markup with input and output. While image arrays or file paths specify the input, developers can define the styling for images and other parts of their app by using CSS and JavaScript at the output.

    4) Module Loaders:

    One of the interesting features that have been added to the latest version of AngularJS is Module Loaders, which allow developers to load the required modules at runtime, thereby reducing the need to depend on WebPack or a similar loader.

    In fact, you can use the new Module Loader in your existing build systems, as it provides support for Babel, Webpack, and other systems. Moreover, Module Loaders in AngularJS v15 are super light and fast.

    5) Increased Stability:

    One of the most important features of AngularJS 15 is that it is compatible with all the previous versions of the framework, which means your applications on any version of AngularJS will seamlessly work on the latest framework without needing any change.

    In addition, the new version offers improved forms with improved access control for inputs, including the ability to define the type and length of input values. The new forms are also more secure and the probability of errors is greatly reduced when making complex forms.

    6) MDC-Based Component:

    Another feature that has been added to AngularJS 15 is called the MDC-based component. This feature allows developers to write their components in much more detail and use TypeScript for the same.

    In addition, this feature will provide support for modules and allow developers to use NgModule and other modules when building components.

    The new MDC component feature allows developers to create custom components from their existing components, i.e. reuse their components without the need to create one from scratch every time.

    The Process To Upgrade Angular 15 From 14:

    Angular v15 Launch Event

    Upgrade to Angular 15 from 14 is an easy task, and one can update Angular dependencies to the latest version by using the below method:

    A) On Linux/Mac:

    npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations}@latest typescript@latest –save

    B) On Windows:

    npm install @angular/common@latest @angular/compiler@latest @angular/compiler-cli@latest @angular/core@latest @angular/forms@latest @angular/http@latest @angular/platform-browser@latest @angular/platform-browser-dynamic@latest @angular/platform-server@latest @angular/router@latest @angular/animations@latest typescript@latest –save

    After following the above step, run whatever ng serve or npm start command you normally use, and everything should work.

    Do remember, that if you rely on Animations, import the new BrowserAnimationsModule from @angular/platform-browser/animations in your root NgModule. Without this, your code will compile and run, but animations will trigger an error. Imports from @angular/core were deprecated, use imports from the new package import { trigger, state, style, transition, animate } from ‘@angular/animations’;.

    If the above steps are followed in line, it should work. But, in case you face any errors, follow the Angular Update Guide (https://angular-update-guide.firebaseapp.com/).
