What are some good file naming conventions?

Are there, if any, file naming conventions for Meteor?

My app is getting more complex; now I have two similar file names (one on the client and one on the server). I’ve found numerous articles on file structure for Meteor, as well as template naming conventions, but I could not find anything on naming files. Are dashes (-) frowned upon? Which keywords should I use or not use? Etc.

Don’t think there’s any official convention, though the Meteor docs shows files using dashes (feature-y.js) & SpaceTalk also uses dashed-case.html

I’ve also been using dashes & as for similar file names, in one my projects I’ve used something like client-helpers.js and server-helpers.js, though I’m not too keen on this honestly since they are already in their respective client & server folders it seems unnecessary…
