Nice 👍

[fklingler]

It seems to work for me, fixing the problem I was talking about here: #447 (comment) 👍

[bebraw]

Published in 0.27.3. Thanks for the confirmation.

[fklingler]

Ok I've got some bad news... I just realized it doesn't work when the sourceMap option is present.

I have to set

  node: {
    Buffer: true
  }

in the webpack options for this to be working.

@fklingler That's confusing in #454 the opposite seems to be the case :D, can you show the bundle output and maybe make a small test repo for reproduction, there is a small bug somewhere. Please move the discussion to #454 aswell to keep it at one place 😛
