Hey, Angular 8 targets es2015 and doesn't have emitDecoratorMetadata enabled. Which seems to make this library fundamentally incompatible with the newest version.
(see also: angular/angular-cli#15077)

I may totally misunderstand all of this (new to this ecosystem) but as I understand it, this library uses the "Metadata Reflection API" in a way which depends on emitDecoratorMetadata to be true which means we can't target es2015 right?

So as I see the only options are to either use es5 or stop using angular2-jsonapi? (correct me if I'm totally off the tracks here)
