importing functions - NodeJS - non-html

Question

I am learning automation for work and currently a little stuck. So far stackoverflow has been a life saver :)

I am writing a test for selenium in visualstudio in javascript (nodes). I understand this is not a great combination but thats what work wants.

I have a test in the app.js file (see screenshot). It references a function in the functions.js file. I cannot get it to recognise the function though. I presume I need to reference the files containing the function. I have tried import 'import cellFromXLS from "functions.js";' and it does not work(Unexpected token import error).

Any ideas on what I can do? Anything fancy like modifying the package.json file to include all files with functions in them? I am on the latest node.js and the latest drivers.

Also it seems intellisense does not work for javascript in visual studio. Is this right or anyway to fix it? VisualStudio screenshot

In functions.js: cellFromXLS = function (cellId) { //Define sheetNumber var sheetNumber = 0; //Define file Path name var fileNamePath = ('trial.xls'); //NodeJs read file var XLS; if (typeof require !== 'undefined') { XLS = require('xlsjs'); } //Working with workbook var workbook = XLS.readFile(fileNamePath); var sheetNamelist = workbook.SheetNames; var value = workbook.Sheets[sheetNamelist[sheetNumber]][cellId].v; return value; }; module.exports = { cellFromXLS } — Endorium, Jul 26 '17 at 09:15
In apps.js: const functions = require("./functions.js"); functions.cellFromXLS('A1'); — Endorium, Jul 26 '17 at 09:16

Node doesn't support import natively just yet.

In your functions file you can do something like

function blah(){
    console.log("I am blah")
}

function wah(){
    console.log("Wah wah")
}

module.exports = {
    blah,
    wah
}

then in app.js you can do:

const functions = require('./functions.js')
functions.blah()
functions.wah()

I have tried the above but I get a messge saying my function is not defined? I put the export lines in functions.js and the 'const' line in my app.js – Endorium Jul 26 '17 at 09:02

Not sure then, it's working in my instance and screenshot. Oh well hopefully you get to resolve it. – wafs Jul 26 '17 at 09:36

The error already tells you what's wrong. You need to use

const cellFromXLS = require("./functions.js");

instead of

import cellFromXLS from "functions.js"

if you want to use the import syntax, check out Babel

ok, I dont want to use babel as its extra thing the business has to validate (Very heavily audited industry). I thought nodejs now supported import from version 8? I wil ltry the other way as you suggested. – Endorium Jul 26 '17 at 08:56
