Hi,
I'm also getting this in phantomjs!
I'v followed the webpack instructions to the best of my knowledge but get this error when running in phantom :
ReferenceError: Can't find variable: Map

TypeError: 'undefined' is not a function (evaluating '_joiBrowser2.default.object()')

Super annoying as joi is amazing! and we need our e2e tests to work!!
Look forward to any help,
Stephen.

I guess we'll need to tweak babel, possibly including the corejs/babel polyfill for Map

[maitriyogin]

hmm we're already including the babel-polyfill when we run e2e.
Is there anything else I should try and tweak ?

entry: {
    app: [
      ...(__IS_E2E ? [
        'babel-polyfill'
      ] : []),
      ...(__IS_DEVELOPMENT ? [
        'webpack-hot-middleware/client'
      ] : []),
      './src/index.js'
    ],
    vendor: require('./src/vendor')
  },

/Stephen.

Version 9.1.0 is not working in IE10, even when I added coreJS/babel polyfills.

It is working in IE10, when I changed the version to 9.0.0. 'new Map()' is not there in this version and it is working fine.

Thanks for your quick reply and suggestions:)

Hi, fixed it by importing Map to test bundler directly. Maybe not the best solution, but works. I had to import Promise as well

import Promise from 'es6-promise'
import Map from 'es6-map'

@Stas-Buzunko thanks for reporting back. I guess we can add that to the readme and people can include those polyfills if they need them for their browsers. Probably not needed in most newer browsers.

I've added a note to joi-browser and joi-full about how to add in Promise and Map polyfills if needed in th README's. Let me know if there is anything else you all think we need to do.
