Default Differential Loading is here with Angular 8 - Archived
The new release of Angular is here, with improvements to the framework, Angular Material, and the CLI designed to improve application startup time on modern browsers. There are also new APIs to let developers make better use of the CLI.
WebWorker support is better in this release, making it easier to . offload work such as image or video manipulation to a background thread. meaning you can write code that moves expensive computation to a separate thread, and have that bundled in a separate script that works in the browser. You can now generate new web workers from the CLI, use it in your application, and the CLI will be able to bundle and code split it correctly.
There’s also a new Builders API in the CLI that can be used by tooling developers to replace the behavior of CLI commands such as build and test.
