Let's say for example you have a key.pem file in a https folder and you want it as a parameter for your server options. You can get it via fs.readFileSync. Hope this helps.

const path = require("path");

server.httpsServerOptions = {
    key: fs.readFileSync(path.join(_dirName, "./../https/key.pem"))
};
