This is a chat application, implemented using Flask-SocketIO with both the database (PostgreSQL) and the app deployed in Heroku. It also has user registration and authentication functionalities.
I followed this 13-part video series by Sandeep Sudhakaran where he built this app from scratch.
- application.py: This is the main app file and contains both the registration/login page logic and the Flask-SocketIO backend for the app.
- models.py: Contains Flask-SQLAlchemy models used for user registration and login in application.py
- wtform_fields.py: Contains the classes for WTForms/Flask-WTF and the custom validators for the fields
- create.py: optional file only required if repo is to be cloned. See 'Usage' section below.
- Procfile: file required for Heroku
- requirements.txt: list of Python packages installed (also required for Heroku)
- templates/: folder with all HTML files
- static/: for with all JS scripts and CSS files
Use the link to the production server directly.

Modify application.py to replace the secret key (i.e. os.environ.get('SECRET')) with a secret key of your choice and the database link (i.e. os.environ.get('DATABASE_URL')) with the link to your own database.
The two lines to be edited in application.py are shown below:
app.secret_key=os.environ.get('SECRET')
app.config['SQLALCHEMY_DATABASE_URI']=os.environ.get('DATABASE_URL')
