Same problem :(

Thanks for the reports. This is caused by ui-router-visualizer which uses the preact library. Preact added typings that are incompatible with typescript 2.0.x

Here's the related issue: preactjs/preact#466 (comment)

I'll see what can be done about this. I believe angular 2.x doesn't support typescript 2.1.x and above. I'll be updating this sample app to use angular 4.x ASAP

OK this is fixed now. I've also updated the sample app to 1.0.0-beta.5
