You saved my life! That amazing feeling when you tried to find some API for qr-code generation, but found the library.

Helpful content. Before I watched this video I thought I would have to pay someone to customize a QR code for me. Thanks again.

Thank you so much, I've had an issue encoding Qr codes in Cordova plugins, but now everything is made simple.

I really love this video. Is there a way I can create a scanner on web to scan the QR code and get some inform from it?

Any idea how I can get qr code In base 64 format, I tried getting src attribute and it is even visible in html but returns empty when try to access programmatically

Hello, thank you for your work. I am impressed. I have a question that may be a little simple. To share a qr code: do I have to host it on a server or can I leave it on my computer? I've subbed to your channel too.

This qr code is estatic or dynamic? And another doubt is qr code event base or process based?

[doomfry]

Does the qr code have to be in a separate/external JavaScript file or can the qr code and the rest of the js script elements such as animations be all in one js file? And will the qr code still work in one js file? Sorry for asking this I'm still learning the ropes on JavaScript. Planning to be a Web Designer
