how to export a function from one file to another node.js?

Question

I have some function that needs to be accessed from another file. But for some reason I can't do it.

 creatureScreenfunction (dir, jsonFile, pathToFile){
    let Mode = require('stat-mode'); 
    let temp; 
    fs.readdir(dir, function(err, items) 
.............................................
   
}

Here's what I tried

exports.creatureScreen = creatureScreen();

in second file

const index = require("../index.js");

You need to use module.exports and if they are in the same directory you will have to do require('./'something.js) — Ozan

What you did here exports.creatureScreen = creatureScreen(); is named export. While importing it in some other file you need to do const {creatureScreen} = require("../index.js");.

You should assign the reference, rather than executing it at the time of the assignment. What I mean is replace exports.creatureScreen = creatureScreen(); with exports.creatureScreen = creatureScreen;.
