I am trying to proxy requests from my containerized React application to my containerized Flask application.

I was starting the application using npm start (in Docker), and I did not have any issues proxying requests. However, I learned that npm start is not a good way to proceed in production.

Following the advice here: Run a React App in a Docker Container , I am able to start my containerized production React, but now the requests are not proxied.

Within the React app, all requests are handled with axios and are formatted: "/api/v1/endpoint". It seems that others have had issues between "http://localhost:80/api/v1/endpoint" and "/api/v1/endpoint". I do not believe this is my issue, unless it arises only in the production environment.

I have also tried changing my "proxy" address in package.json to the location of the dockerized flask container, and later to the name of the docker container, but I have not been able to make either solution work.

If anyone can provide guidance on launching a containerized, production React app that proxies requests to a backend container, please advise.

I am open to using a different server, if the procedures in "Run a React App in a Docker Container" need to be updated.

I have looked these solutions:

I need help uploading a file directly from an HTML form to an API. I've seen this being done for remote URLs, but I don't know how to do this for local files? I tried writing this, but its not working:

I'm Doing the tutorial (https://www.youtube.com/watch?v=dam0GPOAvVI&t=2412s) it was working nicely since there was a problem I don't what.When I run the main.py

TL;DR: Interested in knowing if it's possible to use Abstract Base Classes as a mixin in the way I'd like to, or if my approach is fundamentally misguided.

I have a Flask project I've been working on. As part of my project, I've implemented a "RememberingDict" class. It's a simple subclass of dict, with a handful of extra features tacked on: it remembers its creation time, it knows how to pickle/save itself to a disk, and it knows how to open/unpickle itself from a disk:

I'm trying to learn Flask and use postgresql with it. I'm following this tutorial https://realpython.com/flask-by-example-part-2-postgres-sqlalchemy-and-alembic/, but I keep getting error.

The situation:

I am using React in the front-end and a Flask api server. I am wanting to send the data from React to the api and once I have done this I would like to use WTForms to run validations on the data before handling it. The question may seem similar to CSRF Protection with Flask/WTForms and React , but this does not answer the question, please take a look through I have put a lot of effort in writing a good question.

What I have

Currently the data is being sent successfully as a json object, where the keys match the names within the wtform structure, the aim is to get wtforms to take that json data and insert it into the object and and handle from there as normal

The JSON object being sent
