I didn't realize how bad the course shopping experience was... so here's a way to make it better!
Every hour, a GitHub Action will run which sends a request to the class schedule to fetch all the courses in one request. From there, it will detect which courses have changed (whether it be if a course has been created, or seats have been filled/created/vacated), and fetch more details if so. It then recompiles all this data into a new database and pushes that to the server.
The database is freely exposed in the window with the variable db! Open the console with CTRL + SHIFT + C, and type db to print the database.
To develop in the repository, you must run npm install --force in the root directory after cloning. This is because there is a version conflict between the version of Svelte this project currently uses and the ones some of the libraries I use support, but it causes no issues, and can be ignored.
You must also run npm install in the .server directory.
Then, you can run npm run dev in the root directory to start the dev server, or npm run dev in the .server directory to run the GitHub Action script (for updating the class schedule).
