I have an app I'm writing using Meteor, Angular2 (using the angular-meteor package), Typescript, and MongoDB. I'm trying to put it up on Heroku and running into difficulties. I'm using this meteor buildpack. I'm not sure whether the problems are with Meteor, Heroku, or Angular2, though I suspect it's something Heroku isn't configuring correctly for Angular2. The site is at http://alfred-zahner.herokuapp.com/ and the error I'm getting is:
EXCEPTION: No provider for t! (e -> t)
I've checked the Heroku logs and there is no sign of trouble there. Part of my problem is that I can't see what t and e are, as someone (Heroku?) is uglifying the JavaScript. I'm not really sure how to proceed in debugging this.
One way to solve this problem would be to figure out and fix the error, but I'd be happy if there's a better build pack, or even a better (must be free!) hosting environment that I could be using.
Edit
It's not Heroku's problem. The same thing happens when deploying to Meteor's built in deployment testing (meteor deploy site.meteor.com). If I deploy using meteor deploy --debug site.meteor.com, however, it works, so Angular2 has some problem with the extra processing that happens when Meteor prepares an app for production.
On the angular2-meteor Github I found out that this is an issue with Angular 2 in particular, when using UglifyJS. For now, it seems the only solution is to use meteor deploy --debug. I'm planning to just use that on meteor's built in hosting until Angular 2 plays nicely.
