How we can deploy a Flask + React Application to Azure?

I want to create a machine learning app with Flask as backend and keep React JS as the front-end. Though I found couple of tutorials how to do that but there are very few in terms of deployment. I want to deploy and host a Flask+ReactJS app to Azure cloud. Is there any good tutorial or link which I can follow. I have been struggling for days now.
Thanks

To achieve the above requirement you can find the below mentioned sample resource to create and host flask and react app in AZURE.
To do that we will need to setup the flask app as backend and then React app.
Please refer this BLOG for complete setup to build.
For more information you can refer the below links:-

Python + Node.js on GAE

I have a Django application deployed on Google App Engine standard environment. I am interested in server side rendering of my JS frontend. Can I use node.js alongside Django on the same GAE? Maybe as microservice?

What you can do is to deploy each of your app as a separate service in App Engine and they will work independently as a microservice. To do so, make sure to set a service name for each of the app.yaml file of your apps:
service: service-name
Afterwards, you can communicate between your services through an HTTP invocation, such as a user request or a RESTful API call. Code in one service can't directly call code in another service.
Refer to this link for additional information about communicating between your services.

I have come across articles that talk about integrating python and Node but I personally haven't done it or seen it done on GAE.
If I were to take a stab, I think you would be looking at something like
Have the python app as a service (say it's available on python_service.myapp.appspot.com
Have your Node.js as your default service available on myapp.appspot.com
Your Nodejs will have a route and when this route is invoked, you make an http request to the python service, wait for a response and then your Nodejs app returns that response.
Our App, https://nocommandline.com is an Electron App (combo of Node.js & Vue.js) If you purchase a license and try to validate it, we make a call server side and our server side is Python based. It's not exactly the same thing you're looking at (since our App is not web-based) but this gives you an idea of what I was trying to describe.

IBM Cloud Functions Python API to open a local file browser to upload file

I'm working on a Watson Assistant chatbot that connects to IBM Cloud Functions through Python API. I want to make the chatbot open a local browser window to upload a file from local machine to save it into a database. I'm intending to do that through IBM Cloud Functions Python API.
However, I'm a bit confused on how to make the python API open a local file browser window to make the user select a file from the local machine.
Any help in that, please?
Thanks,

IBM Cloud Functions run on servers in the IBM Cloud. They are intended to run short(er) workloads without any user interaction.
What you are looking for is a chatbot app which calls into the Watson Assistant service. The app is a wrapper around the dialog service. It gets the user input, sends it to Watson Assistant, receives the answer and prints it for the user.
As add-on, the app could open a local file browser and send a file to Watson Assistant. Note that Watson Assistant would not know what to do with that file.

How to connect to flask server from flutter app after build?

I have my flask app which would serve my flutter app using HTTP requests. Everything is okay when the mobile phone is connected to the PC. But once after we deploy the app to the mobile phone and detach it from the PC, how would the flask app serve the flutter app?
Is there any way which would start the python script when the flutter app is launched in the mobile phone?

for testing purpose you can use ngrok to deploy your flask server, for more info ngrok

Your phone when connected to the PC is accessing a Flask app via 'localhost'. You have two options to make it work (i.e. access Flask based REST APIs from the mobile when not connected to the PC).
Expose Flask app to the network. And make sure both PC and the mobile phone are on the same wifi. This link might help for that.
Deploy the Flask based APIs somewhere. There are few free web servers available out there (e.g. MS Azure). This or this link might help.
