How to pass array from server node js file to client simple js file with scripts?

Question

JavaScript

There is a server node js file in which the database is processed and transfers all the information to the object. Like this:
index.js file

function returnOrderArray() {
    var i = 0;
    const promise = new Promise((resolve, reject) => {
        connection.query('SELECT * FROM orders', function(error, results) {
            while (i < results.length) {

                order.id[i] = results[i].id;
                order.wavetype[i] = results[i].wavetype;
                order.color[i] = results[i].color;
                order.thick[i] = results[i].thick;
                order.readydate[i] = results[i].readydate;
                order.createdate[i] = results[i].createdate;
                order.manager[i] = results[i].manager;

                i++;
            }
            resolve(order);
            // console.log(order);


        });
    });
    return promise;
}

When trying to pass an object through module.exports on the client side, the object is not visible
here the export occurs:
index.js file

app.get('/orderlist', checkUserSession, async function(request, response) {
    returnOrderArray().catch(error => console.log(error)).then(() => console.log(order), module.exports.order = order,
        response.render("orderlist.ejs", { username: request.session.username }));
});

and here import :
file orderlist.js

var ind = require('../../index')


function asd() {
    alert(ind.order);
}

just in case file location:



What could be the problem and what is the best way to pass the order object to another js?

Answer 1

I don’t know much, but it seems that through socket.io you can transfer objects to the client, and dynamically through event subscriptions from the server to the client and vice versa, and I would call the function getOrders(filter={bububu, bububu}) for example

Answer 2

Wait, are you exporting from a server script to a client script??? I'm afraid that won't work.
Data between the server and the client must be transferred via HTTP transport
