To kickstart a discussion:

Does anyone use the MEAN stack: mongoDB, ExpressJS, AngularJS and NodeJS?

I am starting a project and currently I am leaning towards NodeJS with Express and MongoDB on the server-side and RequireJS(or WireJS) and Knockout on the client side. I intend to use QUnit for the client app's testing, but have no idea what should I use for Node testing (unit and load/stress). Since it will be just me, I will probably setup Jenkins on my own machine for a build server. I am currently using appfog for staging/testing.

That's pretty much it. (My project includes a mobile part as well, but I guess this is outside of the scope of this discussion, so I wont get into that.)
