Angular 16 features: signals, hydration, and more!
Angular is a more robust and versatile framework for building modern web applications. Version 16 builds on the foundation laid by previous versions, introducing powerful new features like the Signal API and Advanced SSR capabilities while refining existing tools and enhancing performance.
Signals: reactive values made easy
Angular 16 introduces the Signals API, which provides a reactive programming model for Angular applications, and it enables developers to create reactive variables that automatically update the UI when their values change, simplifying state management and improving performance.
Building on the Signal API, Angular 16 offers more granular control over reactivity with Signals and Effects. This allows developers to manage and react to state changes more efficiently, leading to more responsive applications.
This great video on YouTube introduces you to Signals with a simple and practical example.
Enhanced standalone Components, Directives, and Pipes
Refining the standalone component model introduced in Angular 15 with better support for dependency injection, more flexible configuration options, and improved tooling to streamline the development process.
Advanced Server-Side Rendering (SSR) Capabilities
Advanced SSR features, such as incremental hydration and improved streaming support make SSR more powerful and easier to implement, resulting in faster initial load times and better SEO.
Angular DevTools Enhancements
Angular 16 introduces updates to Angular DevTools, providing better performance profiling, enhanced debugging capabilities, and new features to assist in identifying and resolving performance bottlenecks.
Improved Content Projection with Multi-Slot Transclusion
Angular 16 enhances content projection by introducing multi-slot transclusion. This feature allows developers to define multiple content slots within a component, offering greater flexibility and control over how content is projected and displayed.
Better Integration with Web Components
This version improves Angular’s integration with web components, making it easier to use web components within Angular applications and ensuring better compatibility and performance.
Improved Accessibility Features
Angular 16 places a strong emphasis on accessibility, introducing new tools and features to help developers create more accessible applications. This includes enhanced support for ARIA attributes and better tooling for accessibility testing.
Advanced CLI Commands and Tooling
Angular CLI continues to evolve with Angular 16, offering new and improved commands that simplify common tasks. These enhancements include better support for monorepos, improved build performance, and more intuitive command syntax.
Smaller bundle sizes and enhanced performance
Angular 16 includes numerous optimizations to reduce bundle sizes and improve runtime performance. These changes help deliver faster applications with lower resource consumption, benefiting both developers and end-users.
New and updated Angular Material components
Angular Material receives significant updates in Angular 16, including new components, improved theming capabilities, and enhanced accessibility features. These updates provide a more comprehensive and modern UI component library for Angular applications.
Deprecations and Cleanup
As part of the ongoing effort to keep the framework modern and maintainable, Angular 16 deprecates some older APIs and features. Developers are encouraged to review the deprecation guide and update their applications accordingly to stay up-to-date with best practices.
