A simple web app for displaying (reasonably) up-to-date enrollments in courses at Minnesota State University Moorhead for the current semester.

Live demo: http://headcounts.herokuapp.com

• Search and filter courses by subject, college, term, LASC area, writing intensive, and more
• Responsive, modern UI for desktop and mobile
• Download results as CSV or Excel files
• Summary statistics: credit hours, tuition revenue, empty seats, and more
• Disclaimer: Data is not real-time; it is scraped from the public-facing MinnState-maintained course search tool.
• Powered by:
  • Flask (web framework)
  • Bootstrap (styling)
  • Polars (data processing)
  • Hosted on Heroku

When data for a new semesters' courses becomes available, the following steps are needed to update the app:

1. Edit the DEFAULT_TERM variable in config.py to be a tuple with the new term code and name (e.g., ('20265', 'Spring 2026'))
2. Edit the SEMESTERS_LIST list in config_terms.py to add a new tuple with the new term code and name (e.g., ('20265', 'Spring 2026')) to the list.
3. Edit daily_update_script.sh to change the year_terms variable to a SPACE-delimited list of terms to scrape.
