How to do barcode recognition in PHP or JS in web application?

Question

Barcodes

I am making a web application for viewing data from PCs and mobile phones using PHP, JS, CSS, HTML. Without any frameworks.
Need to make a barcode scanner for mobile phones.
Made the output of streaming video through the front camera. I can take images (screenshots) from this video, too, in the stream. Now the task is to learn how to decode these images for barcodes and display the barcode code in a line.
How can this be implemented?
I'm trying to find libraries, and they are for applications on mobile phones.
I just need to implement the task through JS or PHP.
