@mjackson Thoughts on this? Do you still want to hold off on adding this to the build? Seems like both the benefits and the drawbacks are correspondingly minor. |

Where do you get the --blacklist
flag from? I don't see it in the docs.

Basically, this is supposed to do all transpiling except for modules, right?

The docs on the page now are for Babel 6. This is a Babel 5 option to disable a specific transform, per https://github.com/babel/babel.github.io/blob/862b43db93e48762671267034a50c30c00e433e2/docs/usage/options.md#options.
This is just making a build that is applying all of our normal Babel transforms, except for the ES6 module transform, leaving the import
/export
statements intact. It even properly transpiles the ES7 export extensions we use on index.js
to be vanilla ES6.

Exactly. It will look a little different with Babel 6, since --blacklist
is gone there, and everything goes through plugins and presets, but it would thematically be very similar.
This has been open for a week or so now - should we move forward with this change, or drop this for the time being? On balance I think adding the ES6 module build adds enough value for our users to justify the additional configuration involved that this PR adds. (Please don't merge as-is, though - at least not with the commit comment the way it is.) |
Should this actually be |
Going to merge this shortly unless it turns out there's a good reason to bundle this build. |
Should be noted perhaps that webpack doesn't look up |
Fair point, but if it's an upstream issue, I think it's okay to wait for a bit before addressing. |
@taion Please get approval from either @ryanflorence or myself before merging stuff like this. Neither of us actually want an ES6 module build at this time. |
Closes #2524. Replaces #2523.
Don't merge this, it's just a strawman to show what we'd have to change.
