Transpiling es6 into es5

Ran into a problem today at work, wondering if anyone could offer some guidance. Im trying to accomplish roughly the following described below.

Files im working with:

1. config.js : config file using es6 syntax (particularly using import keyword).

2. script.js : node script written using node version that does not support the use of es6 syntax (particulary using import keyword). script.js aims to read the contents of config.js

   //config.js
   import _ from 'npm:lodash'
   import foo from '../otherRandomFile.js'
   var configObject = {
     randomConfigOne: true,
     randomConfigTwo: false
   }
   export default configObject;
   
   //script.js
   var config = require('../app/config.js)
   //cannot console log as below because script barfs
   //due to import being a reserved wrk
   console.log(config.randomConfigOne);
   
   

Question: What do I have to do in script.js so that I will gain access to the object exported by the config.js file without the script barfing about the fact that im trying to use es6 sytax in the file im accessing.
