I have used create-react-app for my project. I am getting an error of

Uncaught SyntaxError: Unexpected token export

The error is in this code

export const ENGLISH = {

  lang: 'en',

  messages: {

      'nav.translatedMessage': 'Social',

  }

};

I tried installing babel-preset-es2015 and babel-preset-stage-0. Also i included the babel dict/object in package.json as

babel: {

    presets: [

      es2015,

      stage-0

    ]

  },

I am still getting an error.
