How to monitor the barcode scanner on the site and display the data on site N when receiving the code?

Question

JavaScript

I understand that there is software that, when receiving a barcode, data about it would appear in a certain database.
But I'm more interested in a simple implementation, independent of the admin panels, where the site constantly monitors the scanner and when it scans the product, produce js code and display N data.
How can this be done correctly? Personally, after searching among those bits of information, I found little. =(

Answer 1

You can try to do this on Node.js or on Electron

Answer 2

As a rule, scanners are ordinary keyboards, the most correct option is to take a raspberry or an arduino, stick a scanner there and push scans somewhere in the cloud for iot, while the site itself knocks on IP and checks. But better describe the business process
