How to use an array data in node js from a javascript file?

Question

I have some data stored in an array in javascript and want to use that array in node js. I tried this:

JS:

let myArray = ['data1', 'data2'];

Node js:

let myArray = require('scripts.js').myArray;

But I get Error: Cannot find module error.

What should I do?

You should tell use where 'scripts.js' is on the file system relative to your Node script. — Mark

The node.js file is in root and scripts.js is in public/scripts/scripts.js I think there's no problem in path. @Mark_M — Ahmet Ömer

Then you have to require './public/scripts/scripts'. Or './scripts' if the file was in the root folder. Notice the dot in the front of the string. — Mika Sundland

You are using the syntax to import a node module: e.g.

const app = require('express')

Node is looking for a node module named script.js

If you want to require local files you need to use the syntax

let myArray = require('./scripts').myArray;

No need to put the .js on the end require does this for you. The full details in the documentation are here: https://nodejs.org/api/modules.html#modules_modules
