如何将对象从单独的文件导出到Node和Javascript？

Question

I have a file called utils.js which has some constants and I'm building a socket app which uses Node for backend work and regular Javascript for frontend. The names of the socket events are identical in both frontend and backend so I want to use the constants both in backend and frontend. But the syntax for exporting/importing is different in ecmascript6 as opposed to Node so how do I pull this off?

This is the contents of utils.js :

const EVENTS = {
    CONNECTION: 'connection',
    MESSAGE: 'message'
};
Object.freeze(EVENTS);
module.exports = EVENTS;

You can put the objects in JSON file, like events.json , or even event.js is you want plain JS objects. Both the Node and JS have access to this. Then you require/import this file in utils.js and you can do the same on the front end. Front and back ends can handle these however they want.
