Use automatic migration to make your angular codebase use the new inject-based dependency injection. Or follow a manual step-by-step migration, if needed.

Angular developers can benefit from using inject-based dependency injection through its simplified syntax, improved type safety, and seamless integration with decorators.

Instead of relying on constructor parameters, developers can use the inject() function directly where a dependency is needed, resulting in more accurate type checking and early error detection during development.

The inject() function works smoothly with Angular decorators like @Host, @Self, and @Optional, providing better control over dependency resolution.

The Angular CLI offers an automated migration schematic (ng generate @angular/core:inject) that simplifies the transition from constructor-based injection to using inject(). This schematic automatically converts existing code, minimizing manual effort and ensuring a smoother migration process.
