How can I get metadata for the current module in Angular 2?

Question

I want to get the metadata for the current NgModule in order to get the list of declarations and providers in order to fill in a dynamic module I create to display components in a modal.

How can that be done?

You can access the declarations using the reflect-metadata package. You do however need to install this package and include it in your project. After that you can get the annotations like this:

let annotations: DecoratorFactory[] = Reflect.getMetadata('annotations', ModuleClass);

If the @NgModule is the only annotation on there, which I would guess it is, you can access the declarations like this, otherwise you have to guess the right index:

let declarations: any[] = annotations[0].declarations;

And what if I want to get the current module without knowing which one is it? – Andre Soares Jan 27 '17 at 13:39
Unfortunately, there is no such thing as a current module. Because your application can consist of multiple `NgModules` at once. What are you trying to do exactly? – Poul Kruijt Jan 27 '17 at 13:55
If you can give plnkr.co implementation that will be great – Ali Abbas May 25 '17 at 10:09
