How to use javascript to get data from textbook in real time?

Question

JavaScript

A program is running on the computer that writes all the data that came from the modem into a textbook in real time, numbers, letters, and so on, but I want to somehow output this data to the browser and operate with this data, for example, writing to a database or using it in my projects, what is the best way to do it?

Answer 1

It is not clear on which computer on a stationary or on a server?

Answer 2

On pure js, why is js needed? If you need a very simple solution, then write from the modem to csv, and work with it through some interpreted language, such as php or python.

Answer 3

Look at node js express js video tutorials on them, MB does it on simple js too, but I haven’t seen it yet)
