Deep dives
Deferable Views and Opt-in Features
One of the main highlights discussed in this podcast episode is the introduction of deferable views in Angular. This feature allows for lazy loading and deferred loading of specific parts of a component, which provides developers with the power to optimize their applications. It simplifies the process of reducing initial bundle sizes and improves the overall performance. The defer attribute can be used in the component's template to specify which parts should be deferred, and Angular handles the analysis and chunking of these dependencies at compile time. Developers can also take advantage of triggers like on interaction or on hover to control when the deferred views are loaded. Additionally, the Angular team follows an opt-in approach for introducing new features, with a developer preview label indicating that breaking changes may still occur. This method enables faster iteration and feedback while allowing developers to choose when to upgrade to the new features.
