deploy module to remote server that is running node.js - node.js

Question

I'm working on my app.js in node.js
-- trying to deploy server-side script.
Many fine node.js modules need a require('something');
I use NPM locally, which works for require, as modules are nicely visible in the local node_modules folder structure. but now I'm ready to upload or bundle to a host. I can't run npm on this hosted server.
const Hapi = require('hapi');
will result in
Error: Cannot find module 'hapi'
because I don't know how to copy/install/bundle/ftp files to my host.
Hapi is just an example. Most anything that has a require will need something on the host.
I used webpack to create a server side bundle.js but just sticking bundle.js under /node_modules doesn't do anything.
Most modules have a complex folder structure underneath --- I'm trying to avoid copying a ton of folders and files under /node_modules. Ideally, I want to combine the modules into a bundle.js and have those modules visible to app.js
but I am open to other ideas.
I have not yet tried using webpack to bundle app.js TOGETHER with the various modules. Have you had luck with that approach?
thanks.
I've tried to upload hapi files a folder-ful at a time, reaching a new require('something') error at every step.
'use strict';
const Hapi = require('hapi'); // <-- how can I deploy hapi on my node.js server?
// Create a server with a host and port
const server=Hapi.server({
host:'localhost',
port:8000
});
// Add the route
server.route({
method:'GET',
path:'/hello',
handler:function(request,h) {
return'hello world';
}
});
// Start the server
async function start() {
try {
await server.start();
}
catch (err) {
console.log(err);
process.exit(1);
}
console.log('Server running at:', server.info.uri);
};
start();

one approach that worked: using webpack to bundle the back end js.
thanks to

the aha moment... run webpack to create bundle-back.js then
tie bundle-back.js to my node server
**You start your backend server with ‘bundle-back.js’ using:
node bundle-back.js
In other words, include app.js in the bundle with the modules.
