Looks good to me!

The only diff in the outputted JSON files is that they don't have EOLs now. The version file in dist is exactly the same, and I like that we've dropped a few dependencies.

Nice stuff.

Did some unscientific bulk testing of npm run build:package and there's nothing in it for speed.

I don't think the resulting code is much lengthier or less understandable compared to the gulp-based approach.

Thanks @domoscargin

Can you double check your diff direction? After this PR merges we should see trailing newline characters (as a consistency improvement) in fixtures.json and macro-options.json where they were missed previously

Although to reduce the diff size I've kept the 4-space indent (rather than our 2-space default)

🤦 I doublechecked this before commenting and still somehow got it the wrong way round!

@domoscargin Don't worry, it caught me out when I wrote it! Cheers
