You are running a typescript file and calling in a javascript file. JS does not support typings, so http: Http will not resolve. If you absolutely insist on using JS instead of TS you’ll need to replace that bit with @Inject(Http) http, if I recall correctly. Typescript is one of the really nice changes that came along with Angular 2 though. I would strongly looking into it.

Also, if you are interested in more information about why injection works like that, please see Pascal Precht’s post here.

Ok, that makes sense. Curiously, that file was created by

ionic generate provider configuration

the project was created with

ionic start pinch-ui --v2

Why would the generated provider not work directly with the generated ionic project?

Ionic2@alpha was doing some weird black magic with webpack where they were labeling a bunch of files as .js when they were actually typescript files. Their webpack script would recognize that they were actually typescript and deal with them. I thought they had corrected their defaults to provide the correct type extensions, but it is possible they haven’t.

I’ve not pulled a fresh project from Ionic in quite awhile, so I really don’t know what the current status of that is.

Ah, gotcha.

It looks like they have a dedicated flag for starting a typescript project

ionic start pinch-ui --template blank --ts --v2

This actually generates .ts files which seem to work.

Thanks for your help!
