@gpbl, can you try this out before we merge it?

Perfect 👍 with this change I can now require intl without the need to access its internals:

if (!window.Intl)
     require.ensure(["intl"], (require) => {
        require("intl"); // window.Intl is available
      });
}

How do you guys load the locale data?

@madebyherzblut I suspect that if you support a small number of locales, you will probably bundle those locales with intl polyfill into a single file, and you require them all after requiring intl. If your app supports many different locales, then you will probably need to load the current locale individually (using require.ensure) and requiring it right after intl.

Thanks for the tips, @caridy. In case anyone else is wondering, here is the snippet I am using:

export default function shim(cb) {
  let root = window ? window : global;
  if (root && root.Intl) {
    return setTimeout(cb, 0);
  }

  require.ensure(['intl'], require => {
    window.Intl = require('intl');
    require('intl/locale-data/jsonp/en.js');
    cb();
  }, 'intl-polyfill');
}

@madebyherzblut even better you can just require intl without assigning window.Intl:

 require.ensure(['intl'], require => {
    require('intl');
    require('intl/locale-data/jsonp/en.js');
    cb();
  }, 'intl-polyfill');

Sweet, thank you @gpbl 👍

👍 for this PR

For a multi context, you can use :

 var intlRequire = require.context('promise?lie!intl/locale-data/jsonp', false, /^.\/(en|fr).js$/);
 var intlPromise = intlRequire('./' + _current + '.js');

Hi If yu can assist me I would be very grateful. I have to load the polyfill in IE8, using the conditional loading as described above I get an error , 'expected identifier' .
The error occurs within the following code:
finally{r()}})},t}function a(n){var
e={_acceptedDependencies:{},_declinedDependencies:{},_selfAccepted:!1,_selfDeclined:!1,_disposeHandlers:

Has anyone else encountered this issue . If anyone has any ideas could you please give me some advice. Thanks

I haven't, but I will highly recommend the polyfill service instead, unless you're working on an intranet kind of app.
