[keycloak-user] JavaScript Adapter issues after upgrade from 3.0.0 to 3.1.0

Hi all, I have played around with some Angular 4 stuff. I created plain vanilla project through "ng new" and added the Keycloak 3.0.0 adapter pretty much like it is done in the Keycloak GitHub "angular2-product-app" demo. Works quite nice. But the moment I upgrade the keycloak-js npm to 3.1.0 I get the error "keycloak-js is not a module". I am not sure but it looks like the new 3.1.0 adapter contains some buggy or outdated TypeScript definitions. Any ideas how to get 3.1.0 working with Angular 4? Thanks, Thorsten
