München Planscht

Real-time filling level indicator of Munich swimming pools, with historical data.

Architecture

This repository contains only the frontend. The backend — database, scheduled scrapers (cron jobs), and the JSON API the frontend consumes — lives on Val Town in the val fgeierst/muenchen-plantscht-v2.

The backend provides:

• SQLite storage for pool occupancy, water temperatures, and catalog tables.
• Cron jobs that scrape SWM pool occupancy and GKD/Feringasee water temperatures on a schedule.
• HTTP API endpoints, e.g. pool occupancy: https://muenchen-plantscht-pools.val.run/?date=YYYY-MM-DD

To work on the backend, use the Val Town MCP / web editor, not this repo.

Quickstart

pnpm install
pnpm dev

Deployment

The frontend is a static SPA built with @sveltejs/adapter-static in SPA mode (ssr = false, fallback index.html). It deploys via GitHub Actions over FTPS to the /mp/ subfolder of the florian.geierstanger.org server.

Live URL: https://florian.geierstanger.org/mp/

The deploy workflow lives in .github/workflows/deploy.yml. On every push to main it runs vp run build and uploads build/ to server-dir: /mp/. The Astro site at the server root has its own FTP action that uploads to / and does not delete unknown files, so the two deploys never interfere.
