flask-socketio-demo

A simple demo to demonstrate using events to perform client-server communication and display data on a web page. Bitcoin prices are fetched using Coinbase API and displayed in real time.

Installation:

Create environment:

cd project_name

python3 -m venv venv

source venv/bin/activate

pip install -r requirements.txt

Pre-requisite:

pip install python-socketio

Run:

python3 app.py

Go to 127.0.0.1:5000 in your browser to access the flask app.

You could also run the index.html directly in the browser to see the same result.

This approach could be considered as external system connect to our socketio. (Such as ReactJS, NextJS ...)

By default, it will be blocked because we don't config the CORS, but in app.py, we are already config it, so it can be access from the external system.
