What’s new in angular 18 ?
November 20th, 2024
Key trends and expected features in future Angular releases:
Based on Angular’s recent updates (Angular 14, Angular 15, and Angular 16), here are some general trends and possible updates you can expect in Angular 18 or future releases:
1. Enhanced Ivy Performance
The Ivy Rendering Engine, which was introduced in Angular 9, continues to be optimized. Future versions of Angular, including Angular 18, may bring performance improvements related to:
Faster compilation and rendering.
Reduced bundle sizes for faster load times.
Improved tree-shaking to remove unused code.
2. Standalone Components
Standalone components were introduced in Angular 14 and have continued to improve. These components allow developers to create and use Angular components without requiring a module, providing a more modular and flexible approach. Expect further enhancements to make standalone components even more useful and easier to manage.
3. TypeScript 5.0+ Integration
Angular typically updates its TypeScript support with each release. As TypeScript 5.0 was recently released, Angular 18 could include full support for TypeScript 5, offering:
Better type inference.
Enhanced performance in build and runtime.
Improved features for strict types and code refactoring.
4. Improved RxJS Features
Angular heavily relies on RxJS for handling asynchronous operations. Future Angular releases, including Angular 18, will likely incorporate the latest features and optimizations from RxJS, making the use of Observables faster and more efficient.
5. Better Support for Server-Side Rendering (Angular Universal)
Angular Universal, which provides server-side rendering (SSR) for Angular applications, has been steadily improving. Angular 18 might bring additional optimizations for SSR, focusing on:
Better hydration (bringing server-rendered HTML to life on the client-side).
Enhanced SEO performance for apps using SSR.
Faster initial page loads and improved caching strategies.
6. Improved Angular CLI
The Angular Command Line Interface (CLI) has always been a powerful tool. In Angular 18, we might see:
New features for easier generation of components, services, and modules.
Enhanced build and deployment workflows.
More built-in support for modern tools and libraries.
7. More Features for Reactive Forms
Reactive Forms in Angular continue to evolve, and Angular 18 might introduce:
More advanced validation capabilities.
Easier management of form states and errors.
Improved change detection in forms to ensure faster performance in large applications.
8. Improved Dependency Injection System
Angular’s Dependency Injection (DI) system could see enhancements in Angular 18, enabling:
More flexible service configurations.
Better support for lazy-loaded modules and optimized DI resolution.
9. Angular Router Enhancements
Angular’s routing system is critical for handling navigation in single-page applications. In Angular 18, we might see:
Simplified lazy-loading for routes.
Enhanced route guards and access control.
Better integration with dynamic routes for more flexible navigation options.
10. More Flexibility in State Management
While Angular doesn’t provide a built-in state management library like Redux, Angular 18 may offer enhanced support for managing state in large applications with:
Tools for better handling complex application states.
Improvements to the ngRx or similar state management libraries.
Conclusion:
While Angular 18 is not officially released, the general improvements we expect to see align with the framework’s ongoing focus on performance, modularity, developer experience, and modern JavaScript/TypeScript practices. Once Angular 18 is officially released, expect detailed release notes from the Angular team, covering the specific updates and features in full.
