How can I avoid circular dependency when exporting from main file to utils and back in NodeJS?

I have a constructor that I initialize in my main Javascript file that we will call main.js and then I have a separate file called: utils.js, in utils I will just print the name in a function and export back the function to the main file but it gives me circular dependency warning and returns undefined:

const { test } = require("./utils");

class User {
  constructor(name) {
    this.name = name;
  }
}

const user = new User({
  name: "Oscar",
});

console.log("Your name is: %s!", user.name); // Outputs: { name: 'Oscar' }

test() // This gives me undefined and also circular dependency warning

module.exports = {
  user,
};

And then in the utils file I want to simply do:

const { user } = require("./main");

const test = () => {
  console.log("Hello there %s!", user.name);
};

module.exports = {
  test,
}

How can I export back test function to main and avoid having circular dependency issues?

>Solution :

It seems, frist file has tree responsibilities:

1. Defining user class
2. Initializing user class
3. Making something with user

So, good practice is to separate them.
main.js

const { test } = require("./utils");
const { user } = require("./create-user");

console.log("Your name is: %s!", user.name); // Outputs: { name: 'Oscar' }

test() // This gives me undefined and also circular dependency warning

module.exports = {
  user,
};

create-user.js

const { User } = require("./user");

const user = new User({
  name: "Oscar",
});

module.exports = {
  user,
};

user.js

class User {
  constructor(name) {
    this.name = name;
  }
}


module.exports = {
  User,
};

utils.js

const { user } = require("./create-user");

const test = () => {
  console.log("Hello there %s!", user.name);
};

module.exports = {
  test,
}
