Inversify inject decorators return null or error

Expected Behavior

lazyInject should be a usable decorator, instead it’s just null or undefined or something else 😦 Somehow this gets thrown away.

Steps to Reproduce (for bugs)

Create a container (as in https://github.com/buehler/typescript-hero/blob/develop/src/ioc.ts)
use getDecorators to create the lazy inject decorator
export it with export { lazyInject };
get the error below.

@remojansen Hi! I am facing the same problem. I have two modules, let’s call them A and B. Module A exports all classes that I want to be injected and module B exports the inversify configuration (container initialization, bindings declaration and decorators creation). I think that the problem comes with circular dependency. Module A is imported in module B to declare the bindings and module A imports the lazyInject decorator from module B, then the error occurs.

I had a similar issue because lazyInject was exported from my configuration after it was used in service. So that’s why it was undefined in runtime.

You are struggling because the react babel config does not allow decorators, so what you can do is:
