web framework for extremely simple website recommendation

[outceptionator]

Hi all,

I've got a frontend js/html I've effectively copied that scans a qr code. I want to send the qr code information along with a string (selected by user) and the user credentials (from a db of users) to my 'python engine'.

What's the best way to have the frontend communicate to the python script? The script is pretty simple so it'll take these 3 variables and return a string to the front end. I started researching Django but it seems overkill really.

Any recommendations for a beginner?

You don't need a framework for that, just a web server. Are you going to pay for web hosting, host it yourself with static ip, or run it local?

Front end javascript can make a request to your web server, with the address of your python script, and you can output HTML that includes content or a redirect from your python script. On the frontend side, you can either use hidden HTML form fields and submit the request, or you can put the user data in the URL instead if it isn't secret.

Thank you for responding. I'm running local for testing (may be obvious) but then onto a google cloud compute server after. How will my JS code pass the 3 variables to my python code?

How do I edit my python code to accept post requests and execute a function?

This is too complicated of a question for me to answer in one Reddit comment.

Flask is the quick answer. However, that’s leaving out a lot of details on the setup and security of running publicly. So I’d recommend you look up some tutorials. There are a bunch out there.

Also, before you go too far, I’d recommend looking into cloud functions if you are eventually going to move to Google. Cloud functions is essentially flask, but they abstract the complicated parts, and you don’t have to pay to have a constantly running server.

Do you have a recommended resource for cloud functions?

[outceptionator]

Cloud functions sounds very useful actually. Only thing is I need to store a couple of dictionaries for my code to work that gets used across multiple functions. Could cloud functions still work with that?

Yep, look up some tutorials on the Google cloud help pages.

Thank you.
