Create QR Codes with editable URLs + download + save to database

Hi everyone, what would be the best approach to do this in Toddle? I´m trying to build a QR code generator. The user enters a URL (https//www.hello.com) and the QR Code get created. The created qr code should then be uploaded to my database (xano) and the user should be able to download the image of the QR code. Also the URL should be editable so the user can change the URL to https//www.hi.com or whatever without changing the QR code. A user can create only 1 QR code but the URL can be edited any time (imagine that the QR code already got printed and you just need to change the URL because you found a typo but you don´t want a new QR code because then you would have to reprint everything..). I´ve tried asking ChatGPT and Claude, watched a few youtube videos but I couldn´t get this to work. Also using a third party solution is not an option. I would appreciate any help 🙏

You can do it via custom actions but I'd probably look into just using a QR code library
There are a couple that are pure JS
It would be much easier to use those
As to the URL change, I would imagine that is done via redirects
As the QR code doesn't actually change
And the URL doesn't stop working
So for a URL change, you'd have to implement a redirect to the new URL which is not a QR code function but a DNS logic one

@Lucas G Thanks for pointing me in the right direction. How exactly would I go about the DNS logic?

You could do this - both generate the qr and handle redirecting - with Comnoco.

How would I do this? And then I would have to use Comnoco forever right? The thing is that I don´t want to add another tool to my stack but I´ll take a look, thank you!
or is there a way to export everything?

If you use it in your stack - yes it would be part of the solution!
No, just like Toddle, it doesn't make sense to code export from Comnoco, comnoco IS the visual programming language and platform to run on.

So it's very easy to do, you just need to create two API functions like in the screen shots (read them from top to bottom from the inputs, to the logic to the outputs).
1. Creates a QR with your client/customer unique ID then stores the lookup of the ID -> URL in a database of your choice
2. Responds to requests to the URL above, looks up the intended URL target and redirects the browser to it.

@StuartM Thank you so much, this is really helpful! I just created an account to test it out. 😁 Is Comnoco GDPR compliant?

Yes, we don't store your data and are UK hosted. If you are an enterprise customer we can even host it privately.
@NoCode ProCode - thought you might like this?

Unfortunately my country is quite strict when it comes to GDPR. Does it say anything thing about the compliance on the website? I could only find a blog post. And since the data is processed by Comnoco GDPR regulations apply (regardless of whether the data is stored or not). Also I would need a data processing agreement, is it possible to get one? 😬

Yes, sure, no problem, we provide them to customers on paid plans on request. You'll also find a little on GDPR here https://comnoco.com/privacy

As for the redirect, is it "safe"/recommended to do that in toddle? @Lucas G

Depends what you mean by safe

Redirects are usually a server thing but you could do it with toddle’s redirect rules
Since they run server-side

By safe I mean the possibility of the user being able to manipulate the logic. But I´ll try my luck toddles redirect rules. Thank you!
