Competition Finder

A simple web application to find upcoming coding contests in Codechef.com and Codeforeces.com

Important: A Jinja error may occur when logging-in just after a fresh sign-up, reloading the webpage will fix it and take you to the Dashboard!. This is due to some unresponsiveness of SQLite.

Setup and Execution

Requirements

• Python 3.6+
• Python dependencies can be installed from requirements.txt

$ pip install -r requirements.txt

(Use pip3 if both Python 2.x and Python 3.x are installed)

Creating SQLite Database

Initialize the database by executing this command in the root folder. (Use python3 if both Python 2.x and Python 3.x are installed)

$ python

This should open a python console. In the console execute

After the server is hosted locally, open the web page by following the link on the console.

About the application

This is a simple and light weight application which uses Flask as backend server and urllib and beatifulsoup for scraping data from competitive coding websites.

Specifications
