I love meteor for quick app prototypes. This is especially because it has a dead simple templating system, as well as integrated plugins (no need to write gulp/brunch scripts for stylus/coffee/jade/etc yay).
However, I sometimes want to create static sites with meteor. You know, sites that are just plain html with no need for a server (apart from just serving static files).
I think it should be pretty simple. Just don’t use any server-related features (Mongo collections, Meteor methods, etc).
After you build your application as you usually do, open it on browser, go to source and just copy css, js and html to 3 files: index.html, styles.css, scripts.js. Then you can serve these files as a static website.
