Passing in options does not seem to work.

[ronnross]

I'm attempting to set runtime = true for the use of generators in the 6to5-loader. It looks like this:
{ test: /\.jsx$/, loader: '6to5-loader?runtime=true' }

I get an error Uncaught ReferenceError: regeneratorRuntime is not defined

Is there another way that I'm missing to pass in options?

You don't enable generators via runtime. They're enabled by default.

Due this issue, I actually found that webpack assumes 6to5-loader?runtime=true as a string instead of a boolean, which would result in a call to 6to5 similar to:

to5.transform("code();", {
  runtime: "true"
});

that would mess up with the generated output.

A patched version has been published to npm.

@ronnross You need either the regenerator runtime or the 6to5 polyfill.
