Is there an option to exclude a folder from bundler?

My app has a tests directory, in which I stored some files for testing purpose, and I want to exclude them from bundler.
I saw we talked about these feature in the pass, but it sounds like the only one (none official) way to archive that is naming your directory with a . at the beginning of the folder name. I’ve not tested yet.

The problem with that naming option is the root path import/require doesn’t work, for example: require("/.tests/a-big-video-file.mp4")

I asked Germini, it says I can use .meteorignore.

here you can find more references here

IMO it should be documented, are you open to send a PR?
