How to call function from other local file Node.js?

Question

I tried like this from main.js

// Modules to control application life and create native browser window
const {app, BrowserWindow} = require('electron')
const parser = require('./parser.js');
parser.parseHash(url)

But got error that: parser.parseHash is not function

// parser.js file
function parseHash(url) {
    ...
}

Answer 1

Are you exporting parseHash function in parser.js file?

module.exports  = {
parseHash,
}

Answer 2

// parser.js
exports.parseHash = function (url) {
    ...
};

//main.js
const parseHash = require('./parser').parseHash;
parseHash(url)

Answer 3

You need to export the function like this:

// parser.js file
function parseHash(url) {
    ...
}

module.exports = {
    parseHash: parseHash
}
