Basic Javascript + MQTT over Websockets Web App

I am looking for a talented developer to build a basic one page web app. This one page should consist of a form that on submission, sends data using websockets to an MQTT thermal receipt printer which is then printed out.

The project utilises a Javascript library specifically built for thermal receipt printers called "printerlibs_websocket" which comes with lots of examples of code.

I tested the Javascript by opening one particular example page called "[login to view URL]" into my browser (this html page was locally stored so running from my hard disk) and it loaded correctly. I then changed the address field to the local IP address of my MQTT printer, left the port field as "8080", pressed "Print and it successfully printed out the example receipt.

Your task is to implement changes to "[login to view URL]" so it can be uploaded to a web server and print to the same printer. Any additional parameters that need passing from the web form should come from further text fields.

I believe this task will involve the use of a message broker that supports websockets and there are number of Cloud based message brokers which support this protocol such as CloudMQTT. Alternatively you could install a Mosquitto or EMQ broker on a clean VM (Ubuntu 18.04) if you feel that would be more appropriate?

- The freelancer should have knowledge of MQTT, Websockets, Javascript and of obviously some basic HTML skills too.

- The freelancer can use his own webserver or I will provide one with FTP access to test their code modifications.

- The freelancer should deliver a working solution in 48 hours of being awarded.
