I'm not clear on this one. A small example would be very helpful.

This sounds a bit like hot reloading in that there's no hash and special handling.

Could we do this with more options to the javascript_pack_tag rather than new helpers?

lib/webpacker_lite/helper.rb, line 46 at r1 (raw file):

  #   # In production mode:
  #   <%= javascript_pack_tag 'calendar', 'data-turbolinks-track': 'reload' %> # =>
  #   <script src="/public/webpack/production/calendar.js" data-turbolinks-track="reload"></script>

I don't get how you output a non-hashed file in production mode.

I wrote a detailed explanation in the issue (#21). Did you read that?

Yes, this is a style thing. We could either have a new method or keep the same method with a boolean flag. Usually, I get yelled at by the guys for doing boolean flags as that's considered a bit of a code smell, but I suppose we could do manifested: false or some such and default it to true? But then we'd have to pick it out of the rested named params which would be annoying.

Well, that's easy, just don't tell webpack to do it. I think you mean why would you? You probably wouldn't since you would have major caching problems. I can remove that part of the documentation, but technically, it is possible.

@robwise any comments on #20?

[robwise]

@justin808 What do I need to do to get this merged? Switch to a flag?

[robwise]

Closing because you can use the cache option for the manifest plugin to share a manifest between configs. See rails/webpacker#464 (comment)
