Web Programming with Python and JavaScript
A Flask chat app written in Python and Javascript. Live at (Google Chrome preferred): https://flack4cs50w.herokuapp.com/
This web app is written in vanilla CSS and JS.
It uses the client's localStorage together with Flask global variables to store credentials. Flask's session variable was not used for this app.
Users can sign in with no password, just with a unique display name. Channel creation is also possible.
As a personal touch, a file upload feature is added. File upload is limited to jpg/jpeg, png, gif, pdf, and txt files with a maximum size of 2MB.
