In my previous Meteor app, using browserify, and React, all was working until I switched to meteor webpack.

I use react-select in my Meteor apps and it worked great but with browserify I could prevent multiple copies of react from loading which prevents this error I'm now having:

Error: Invariant Violation: addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's `render` method, or you have multiple copies of React loaded (details: https://fb.me/react-refs-must-have-owner).

My package.json look this:

...



dependencies: {

    classnames: ^2.1.3,

    lodash: ^3.10.0,

    react: ^0.14.6,

    react-dom: ^0.14.6,

    react-mixin: ^2.0.1,

    react-select: ^1.0.0-beta8

  },



...

Is there a configuration in webpack I could use something call externals? Not fully sure what that means but a comment said to use:

externals: {

  'react': 'React',

  'react-dom': 'ReactDOM'

}
