While support for ES6 modules arrived as an experimental feature in Node.js 8.5, there are two ways to use these modules on earlier Node.js implementations.
One method is to use the Babel transpiler to rewrite ES6 code so it can execute on older Node.js versions. For an example, see https://blog.revillweb.com/using-es2015-es6-modules-with-babel-6-3ffc0870095b.
The better method is the esm package in the Node.js registry. Simply do the following:
