The team behind Angular says it is coming out with the most significant update since the platform was introduced—the web development framework talks about improved runtime performance through simplified code and increased usability.
Angular is designed for building single-page applications. This solution allows a web page to appear as fluid as a native app, as it refreshes data through a server without having to reload in the browser. The updates in Angular v16 are backwards compatible with the current system.
Reactivity, quality-of-life and more
Angular’s development team has revamped the platform’s reactivity model, although the updated version is still in developer preview mode. This model monitors what data changes and makes those changes for any change to the Web page the end user sees. Previously, it relied on zone.js’ change detection, but the team says this doesn’t work as well on a larger scale as they aspire to. Angular Signals should change this. Unlike a variable, a “signal” only takes computational power when something changes, so runtime performance should be much faster.
In addition, Angular users try out Hydration server-side rendering in developer preview. With this option, Angular does not have to re-render the application entirely. The company warns of some bugs and limitations before fully adding the feature.
In addition, migrating standalone APIs in applications should now be more accessible, thanks to new migration schematics.
