TL;DR: Angular 8 is here! Learn all about one of its coolest new features: differential loading. Differential loading lets you serve up different bundles to different browsers and make your application even faster!
Angular 8 has only been out for about a week at the time I’m writing this, but there’s already been 17,000 “What’s New” articles published. Rather than throw my own take on the pile, I’ll refer you to the official Angular release announcement but here are the high points:
- No, Ivy isn’t ready yet (it’s an opt-in preview).
- No, Bazel isn’t ready yet (it’s an opt-in preview).
- Builders allow you to extend and customize the CLI. For example, you’re now able to deploy to Firebase and other providers from the CLI.
- There’s improved support for web workers, such as the ability to generate them from the CLI and use them in your application.
- Rather than using the “magic string” syntax specific to Angular to do lazy loading, you’ll be able to use the standard
import()syntax. You can even perform this automatically for your app with the
- The new unified location service improves migration from the AngularJS
- The Angular team has created a simplified Getting Started Guide.
- There’s a new Deprecation Guide to assist users with updating Angular.
- Differential loading is turned on in the CLI by default.
In this article, I want to dive into that last one: differential loading. What is that? Why does it matter? What do I need to do about it (if anything)?
