💡 How this works

1. Fetch data from url (fetcher.js)
   • fetch VIEWSTATE + VIEWSTATEGENERATOR from .NET with axios
     • hit login endpoint with a GET request
     • request method: POST
     • enable followAllRedirects
     • set login headers
   • setup request (these settings are important)
     • enable cookies
     • request method: POST
     • enable followAllRedirects
     • set login headers
2. Parsing the data (parser.js)
   • get relevant elements with cheerio
     • timePeriod
     • categories
     • day cards with food items
   • minify html
   • Regex
   • Replace unreadable markup such as internal MensaMax IDs
   • Build JSON from custom markup
3. Serve via rayo http/ Vercel Serverless Function

🏫 Known/ tested institutions

• For a nice GUI version, see https://mensa.vercel.app/institutions-ui
• For the raw data, see institutions.json
• Please feel free to suggest new institutions by opening a PR/ Issue

🧠 General Knowledge

• For some reason, MensaMax IT department decided to have many URLs
  • you can find a list of all known MensaMax URLS @mensamax-urls.txt
• These URLs are not interchangeable and seem to be different MensaMax versions (as of 13.04.2023)
• There is a private/ internal GraphQL API for MensaMax which needs authentication
