Angular+NativeScript is the most popular combination.
Angular with TypeScript services, dependency injection, and routing can create a native-like UI. NativeScript gives programmers native APIs. You get an iOS/Android app. Web and mobile development are separate projects.
Developers need proper training to use Angular, a complex platform. Angular’s extensive built-in features let you create anything, which is excellent for product success. Beginning developers may need help learning Injectors, Components, Angular Directives, Pipes, Services, etc.
Angular template syntax, Angular CLI, routers, and other features simplify programming and speed up application loading. The framework efficiently displays data in the UI using multiple back-end programming languages.
What’s new in Angular v16?
Angular v16 is set to revolutionize state management with signals. With improved developer experience and the natural hydration of server-side rendering applications, developers will have greater flexibility to create engaging user interfaces.
The Angular v16 update also comes with other essential features such as esbuild/vite-based dev server (for ng serve), bind router information to component inputs, DestroyRef as an injectable provider, takeUntilDestroyed() pipe, and Design tokens in Angular Material Library.
Overall, Angular v16 provides developers with an upgraded and seamless experience that will allow them to take their web development game to new heights. The rest of the article will take a more in-depth look at each feature mentioned above and its functionalities.
Let’s discuss these in detail:
Revolutionizing State Management: Signals in Angular v16
Angular v16 has many amazing features and improvements that developers can’t ignore. One key feature that stands out is Signals, which introduces a whole new way of managing state changes in Angular applications.
What makes Signals unique is its inspiration from Solid.js, making it an efficient and flexible approach to managing state changes. It involves functions that return values (get()) and can be updated by calling them with a new value (set()).
Benefits of Signals in Angular v16
● Make Angular Simple: With Signals, developers can reduce the complexity of their applications. In most cases, reactive programming can replace RxJS, making Angular simpler.
● Fine-grained Reactivity: Signals offer more fine-grained reactivity to Angular. Because signals provide exact models which have changed, Angular can do fine-grained updates to the template instead of dirty-checking the whole application. This makes Angular much more performant.
● Fewer Concepts to Learn: With the introduction of the Signals component in Angular v17, developers can worry less about any performance-related issues that may arise due to non-optimal code. Concepts such as changeDetectionStrategy, onChanges lifecycle hook, and even pipe will become unnecessary. This means developers can focus on building great applications without worrying about performance issues.
● Zone-less Application: Currently, Zone helps Angular to know if something has changed and triggers change detection for the whole application. Zone monkey patches the browser API to give signals to Angular that something has changed. But it does not tell the framework what has changed, which adds to the application’s bundle size and initial startup time. Signals would allow the framework to know which exact model has changed, enabling us to have zone-less applications.
● Interoperability with RxJS: Angular provides interoperability with RxJS, the current reactive library used in Angular. Using toSignalObservable can easily convert to Signal, and using toObservable can convert back to observable. This allows developers to migrate things to Signals from RxJS incrementally, taking advantage of Signals’ powerful features.
Improved Developer Experience with Required Component Inputs
Angular v16 introduces a feature set to make developers’ lives easier. With the Required Component Inputs feature, developers can mark specific inputs of a component as required, ensuring that the parent component must provide them, or else an error will be thrown.
This feature significantly improves Angular’s developer experience, helping catch bugs and typos at compile time rather than runtime. Ensuring that components receive all the necessary data to function properly increases the code generation quality of Angular applications.
In addition to catching Testing and debugging early, Required Component Inputs also makes components more self-documenting, helping other developers quickly understand which inputs a component requires. This makes components easier to use and contributes to the overall maintainability of an Angular application.
Improved Documentation and Learning Experience
Angular v16 documentation is more user-friendly, so developers can enjoy the learning experience without the need to scroll down for hours. A fresh new take on Angular has transformed this once-complex tool into a welcoming oasis for curious programmers.
Enhanced User Experience with Real Hydration of Server Rendered Applications
One of the biggest feature requests from Angular developers has been Server Side Rendering (SSR) with non-destructive hydration, and Angular v16 has finally fulfilled this long-standing request. Angular universal provided some SSR support, but only with destructive hydration, resulting in a suboptimal user experience.
However, with the latest release of Angular v16, this problem has been resolved. It now offers non-destructive hydration, allowing for faster initial startup time, improved user experience & performance optimization. This new feature has been highly anticipated and is expected to enhance the development of end-user-facing applications.
With these advancements, the web vitals of Angular applications will likely improve, making them even more user-friendly and efficient. Say goodbye to janky user experiences and hello to faster, more optimized applications with Angular v16’s SSR with hydration.
Other Features and Improvements in Angular v16
Angular v16 isn’t just about SSR with hydration; it also comes packed with many other exciting features and improvements that are sure to make developers’ lives easier.
esbuild/vite based dev server (for ng serve)
Angular v16 will have an esbuild/vite based dev server to speed up the development process significantly. This will allow developers to serve and build their Angular applications faster, resulting in quicker feedback loops and increased productivity.
Bind Router information to component inputs.
Angular v16 now allows developers to data binding router information to component inputs, enabling Angular v16 components to access router parameters and query parameters easily. This feature will reduce boilerplate code and simplify passing data between components.
DestroyRef as an injectable provider
Angular v16 introduces a new feature called DestroyRef ctx, allowing developers to access a component’s destroy context. This can be used for cleanup tasks that need to be performed when a component is destroyed, resulting in more efficient and cleaner code.
In Angular v16, developers will have access to a new pipe operator called takeUntilDestroyed. This operator automatically unsubscribes from an observable when a component or directive is destroyed, reducing memory leaks and making code more efficient.
Design tokens in Angular Material Library
With the addition of design tokens to the Angular Material Library, developers can now define and share design elements like colors, typography, and spacing, leading to more streamlined and uniform designs throughout applications.
Overall, Angular v16 brings new features and improvements that make Angular development even more efficient and developer-friendly. These features will enhance the development experience, improve performance, and streamline workflows.
