How do I go about using variable from multiple files in node js?

Question

I want to get a variable from one .js file to another .js file. Right now I have main.js

const balances = require('./balance');
console.log(balances.balanceBTC)

and I have balance.js

const balanceBTC = () => {
  return arrayCleaned[0];
};
exports.balanceBTC = balanceBTC;

And I am getting the error

const balances = require('./balance');

ReferenceError: require is not defined

I am running this code via windows PowerShell and the node version is: v14.10.1

How are you running this code and what is your node version? — Vasan, Nov 29 '20 at 00:26

check for node and npm is everything installed properly. looks like it's not able to resolve the `require` because of that. — kgangadhar, Nov 29 '20 at 00:48

NodeJS might be treating your code as an ES Module. And CommonJS variables like "require" are not available in ES modules. Try one of the below:

As mentioned here, declare require before using it.

  import { createRequire } from 'module';
  const require = createRequire(import.meta.url);

  const balances = require('./balance');
  [...]

None of these worked for me. I downloaded commonJS and requireJS and it still is giving me the same error. – Lawnmoers The Epic Gamer Nov 29 '20 at 01:12
