I have a server (implemented with NodeJS), and a client (implemented using Vue, compiled with vue-cli) that share some code. The problem is that Vue does not support "type": "module" option, and I cannot run both programs without getting an error from one side or another.

I'm wondering: is that passobile, and how can we use ES6 modules in a NodeJS script, without specifying "type": "module" inside the package.json file ?

Thanks
