Hosting Meteor for development. Site recommendations?

I am new to Meteor. I watched “Your First Meteor Application” and feel that Meteor (if it works as advertised) fits my needs pretty well. I signed up on Cloud 9 to use as a development platform because a) creating a VM on my PC is a l pain b) I like the idea of being able to work on my laptop if needed too. I did manage to get Meteor installed on my workspace, and was able to run the Meteor demo app. But now it no longer works. I can’t view it at Instead of seeing the rendered HTML I see Index of /myApp and a listing of the directory.

I have two questions. What am I doing wrong? But even more important “is cloud 9 the wrong place to do this?”.
