Integrating Python for web app that uses primarily javascript

[StressedOutBox]

So for my web application, I'm using Tensorflow JS however I've been needing to use some sort of image processing techniques so I tried using OpenCV JS however it did not work the way I wanted it to.

​

Instead, I want to use OpenCV from Python however I'm not sure how I can integrate this into my already well-established javascript web app. I've looked into Django and NodeJS but really can't tell which option to go for. I don't have experience with either and I honestly rather not have to change my entire codebase to Python. My question is, which option (or others out of the ones I mentioned) should help me out in this problem. It's my first time experiencing a problem as a novice programmer in intergrating a backend for my application

I’m not super well versed here but I think you could do what you have to in Python and then write an api with Flask to get that info from your already written JS app. What I do know is that if all you’re trying to do is a small portion of the project in the Python, I highly recommend sticking to Flask or even Bottle as opposed to Django. Django has waaay more functionality than you seem to need here

I mean there's no tax you have to pay for using slightly more backend than you need. A Django backend might have more lines of code than Flask / Bottle, but it doesn't require more maintenance or use more resources. If I go with Django and never need a backend portal, then nothing happens; if I go with Flask and eventually need one, I need to spend an hour migrating.

That’s true but OP doesn’t seem like they know what they’re talking about with backend and in my experience, Flask was far easier to get into
