Polyfill for ie

Question

I'm trying to add a polyfill to my vue.js 2.0/Laravel5.3 application because in internet explorer 11 I receive an error:

vuex requires a Promise polyfill in this browser.

So I've followed the docs I'm using ecm 6 so I did:

npm install --save-dev babel-polyfill

And added this at the top in my bootstrap.js:

import "babel-polyfill";

But still the same error in Internet explorer. What should I do or what am I doing wrong here?

Answer 1

If you are using Webpack, find your webpack.base.conf.js file (mine was in the build folder), or the equivalent webpack configuration file, then modify the app entry variable to include babel-polyfill at the start so it looks something like this:

entry: {
    app: ['babel-polyfill', ...]
  },
  .
