There was a problem hiding this comment.
Is it important to distinguish between these two varieties of preprocessed JS? I mean, what's the scenario where you want require(...) but not import?
Anyone who's using webpacker will probably already use Babel (for JSX), right? So do you think one of these options would be sufficient by itself?

I was tempted to scrap all the old style generators but was not sure on the effect it would have with sprockets + babel transpiler. I did what looked safe given I still don't fully know the system and saw the option[:es6] used nearby in the same file.
Will continue on this path a little this afternoon, seems like the most pressing issue for now, then maybe the HMR ( 793 ) thing after once I get time.
The ruby racer pegged libV8 to V3 which is too old for 'Set' which is now standard in JS. The ruby racer therefore cannot be supported this gem.
React is compiled away in JSX transformer using Import syntax

@rmosolgo I couldn't find a way of getting it to accept the migration to Thoughts? |
React.DOM used reactid but createElement does not https://reactjs.org/blog/2016/03/07/react-v15-rc1.html#documentcreateelement-is-in-and-data-reactid-is-out

Yeah, I guess there are other ways to get addons these days, so it's not as important to bundle them here. That two-release plan sounds good, that seems like it would be easier for people to migrate, too. |

Previous version has 3k downloads. Not hearing anything about bugs in its use. Tempting to get ready to merge this one in. |
