The MDL didn't works with Angular in my Environnement. I proceed this tutorial :
https://getmdl.io/started/index.html
The libraries are present in node_modules, but debugger show me message :
[WDS] App updated. Reloading...

lang.js:130 Angular is running in the development mode. Call enableProdMode() to enable the production mode.
it isn't enough to import some scripts from mdl. There needs to be done a little bit more work or you can use a wrapper lib that handles most of the work for you: https://github.com/mseemann/angular2-mdl
