Flack

A live-time webchat using Python and Javascript inspired by Slack. It is a simple webchat that organizes conversations in dedicated channels.

Functionalities

When a user specifies a username, it is then stored in localStorage so user doesn't have to specify his or her username again after closing the browser. In the same way, current channel name that user joined last time is also stored in localStorage.

Due to the project being just a small personal challenge, I decided to just keep the messages in an array related to the room they are sent (instad of using a database). The oldest ones are removed.

Poject saves timestamps in Unix format and JS code converts them into local time and uses Locale browser information to display time and date according to the user's country.

According to CS50 requirements, I added the feature to delete the messages you sent across all the connected clients.

Files

• application.py: Python backend of the project
• static: directory with JS files.
  • index.js: main JS file for the project.
• templates: directory containing Flask templates files.
  • home.html: for this project I used just one page that updates each time an action is done

Environment variables

The application can take four optional environment variables:

• SECRET_KEY: secret key that Flask uses for integrity protection.

Requirements

Install the required libraries via pip by using

pip install -r requirements.txt

Usage

Run the app via flask

flask --app application run
