Angular v22 just made lazy-loading services much simpler. In this post, we'll explore how to leverage the new injectAsync() API to reduce your main bundle size and replace awkward lazy-loading workarounds. We’ll compare the older manual lazy-loading approach with Angular v22’s new injectAsync() API and see why the new pattern feels simpler and easier to reason about.
Every Angular developer is familiar with @Injectable({ providedIn: 'root' }) for declaring services. While powerful, the @Injectable decorator supports many advanced configurations that are rarely used in typical application services. Angular 22 introduces a new @Service decorator designed to simplify service declaration for the most common use cases. This post will explore how it streamlines service creation and even enforces modern dependency injection patterns.
