In my routes file, I export all code and import it at my index.js. What's the purpose of inserting 'app' as a parameter in my export statement?
module.exports = (app) => {
Thanks!
What you are looking is a Arrow Function that accepts one argument.
This module is exporting a default function which can be imported like this
var test = require('./whatever-file');
and now test is a function.
test('a string argument')
Obviously with the little that is posted we can't infer what type app is supposed to be. So, you will need to adjust according to whatever is needed.
