global.js
const data = {name: "John", surname:"Doe"}

module.export = { data }
The page where you want to use global.js
const usingJSON = require("./global.js")

updateFunction() {
// It will work when you do the update here
}

Would you give this a try ?

Your object will not be reset unless the server is restarted.

If you want to store completely permanent data, you need to use a database for this.

In the example below you will see a simple express server example. In every request, I create a new value and add it to the object.

const express = require('express')
const app = express();

const json = {};

app.get("/test", (req, res) => {
    json[Math.random()] = Math.random();
    console.log(json)
    res.status(200).json(json);
});

app.listen(3001);

Result:

{
  '0.7194184298804673': 0.8660271960055534,
  '0.5781764917107222': 0.7342461283679118,
  '0.7488988117603479': 0.8913689704797536
}
