node js: Why module.exports = tesdf() from require is executed only once, inside get request

0

index.js

'use strict'



const express = require('express')

const app = express()



app.get('/', (req, res, next) => {

       require('./test.js') // after repeated request is not executed

       console.log("test")//after repeated request is  executed

       next();

    })



app.listen(8097)

test.js

function tesdf(){console.log("Gtest test", ind++); }

module.exports = tesdf()

How to make a function called again.
thank you.

node.js get require

When you are exporting a file, you export the function, classes or variables. Here you are exporting the result of tesdf() function. To solve this just export it like:

function tesdf(){console.log("Gtest test", ind++); }



module.exports = tesdf

Also you should not use required('./test.js') inside of the get request because everytime some client request for that end point, the method is going to load the file. e.g

let test = require('./test.js');

app.get('/', (req, res, next) => {

       test();//Call the method

       console.log("test")//after repeated request is  executed

       next();

    })

Exporting a module in NodeJS turn it singleton, so an option to make it not singleton is to create different instance:

test.js

function tesdf(){

    console.log("Gtest test", ind++); 

}



module.exports = tesdf;

index.js

new (require('./test.js'))();
