Actually we approve both, but okay 👍

[dhruvdutt]

Can you also clean *.spec.js from .npmignore?

[ematipico]

@ev1stensberg do we? All the file names are *.test.js, I thought we were consistent in that way

[ematipico]

@dhruvdutt why do I have to remove *.spec.js? I don't get

[dhruvdutt]

Because there would be no files with spec.js extension.

[ematipico]

I can do it! But first I'd like to know @ev1stensberg point of you.

[evenstensberg]

Keep .spec, it's not like it's illegal to use another convention 👍
