Export buildStyles from module and not just as bin script

[aparlato]

We have reports from a client that this repo doesn't export the buildStyle function when used in node. It works fine as a binary script.

It should export fine as a module, but if it's not, it may be an issue with parcel as our bundler.

[EDIT] See #21 (comment)
Should we export buildStyles (plural) as a JS function from the module instead of only making this available as a bin script?

I'd be interested to know more about what the user is doing and what isn't working.

I created a bare minimum node package, added mapbox-gl-style-build as a dependency, and imported buildStyle. This all works fine on my end. I'm not actually trying to build styles with it yet but I can definitely see and invoke buildStyle.

My apologies, I just got clarification from the client on what they meant, so am updating the issue:

They wanted to know why we only export buildStyle and not buildStyles or effectively what the bin script is.

I don't feel too strongly about this if we did want to export that, but we would need a slightly different implementation from the bin script.

Oh got it. I'm not opposed to it. Either way we should document that those functions are exported.
