A simple web application using Flask that allows users to upload and download files asynchronously.

Instruction of how to run this project

• Download the 'project-flask-WebApp' from GitHub.
• Follow the README.md file accordingly.
• Run the flask_wa.sql file into a MySQL database environment, I prefer- xampp 'phpmyadmin'.
• Database set-up: MYSQL_HOST = 'localhost', MYSQL_USER = 'root', MYSQL_PASSWORD = '117734', MYSQL_DB = 'flask_wa'.
• Open Flask-Web-App as project folder into any python IDE, I prefer 'VS Code' or 'PyCharm'.
• Create a Virtual Environment inside that folder.
• Install pip and other necessary library packages to run this program.
• Then run the program (run 'python .\main.py' in terminal).
• Check if this- 'MySQL db is connected! ***' string is printed in the terminal to make sure the program is connected to the database.
