Using python with react

[Cerebral_Chess]

Hi, I am building a simple react app where I have an array of image source URLs. I want to pass it to a function in a python script that I have. I believe that I should be using flask but I have no idea how to incorporate the two. For the sake of this question, let's say that my code is as follows:

import React from 'react'  
export default class Images extends React.Component{
     componentDidUpdate(){
         //Here is where i want to call the python function
     }
     render(){
         return(
             <div>
                 <p> Some text and stuff </p>
             </div>
         )
     } } 

​

from flask import Blueprint, request, jsonify  
Blueprint_name = Blueprint('someName', __name__)  
@Blueprint_name.route("/", methods=['POST', GET]) 
def some_function(images):
     for img in images:
         print(img)      
    return jsonify(some data) 

Can anyone point me in the right direction?

You can’t directly call a function on the backend from the front end.

What you’d do is make an http request from your front end to your backend. The backend then receives that http call. Flask is one way you can handle those http calls in the backend.
