Setting up a proxy server to deploy

[AdagioB]

I'm trying to setup a proxy server, to help me connect to some external APIs that doesn't want me to connect directly to them

I have set it up like this:

proxy.js
`const express = require('express');
const axios = require('axios');
const cors = require('cors');
const app = express();
const dotenv = require('dotenv');

// Load environment variables
dotenv.config();

const port = process.env.PROXY_PORT;

// Middleware
app.use(express.json());
app.use(cors()); // Enable CORS for all routes

// Proxy endpoint
app.get('/api/test', (req, res) =>
{
res.status(200).json({ message: 'Proxy server is working' });
});

// Start the server
app.listen(port, () =>
{
console.log(Proxy server listening at http://localhost:${port});
});`

quasar.config.js:
`const { configure } = require('quasar/wrappers');
const PARSER = require('./variables/parser')();
const PROXY_PORT = PARSER.PROXY_PORT;
const proxyMiddleware = require('./src/utils/proxy');

module.exports = configure(function ()
{

return {

// Some code
extendExpress(app)
{
// Include your custom middleware
app.use(proxyMiddleware(PROXY_PORT));
console.log(PROXY_PORT);
// Return the modified Express app
return app;
},
// Some more code

build: {
env: PARSER
// Even more code`

This all works fine in development, but when I build it and copy the files to my staging server, it doesn't work
I would assume that if I go to a browser on the server and call http://localhost:8000/api/test it would work, but it refuses to connect

I have no idea how to debug it. How can I log anything? Where would I be able to see this log? The console.log in proxy.js is not visible anywhere. I know it starts in development, as it works just fine here

... and why doesn't the code sections work? I have added the correct tags to the code sections, but they just show up as normal text

Looks like I will need to set up my system to only use the proxy in development, but call the external APIs directly in staging/production
