Can I use RPI camera for scanning barcodes on node-RED?

It worked with the clean image but if I wanted to read for example a cocoa cola barcode

Then why did you send a clean image????

Are you wanting to scan many different type in different orientations / different surfaces? The underlying decode library is not ideal in this regard. So unless you can get repeatable images fed in, this is not going to be easy & you would probably be better off buying a cheap barcode scanner that interfaces with the PI to feed results to node-red.
