meteocool is a free GIS visualisation & aggregation platform with focus on thunderstorms. Optimized for mobile devices, you can use it to both chase or avoid upcoming weather - that's up to you.

meteocool currently uses radar data provided by DWD and realtime lightning information from the awesome blitzortung.org project.

• Automatic Map Updates: the biggest inconvenience with most weather radar visualisations is out-of-date data. Meteocool notifies its clients as soon as new radar data becomes available and the client tries to be transparent about the dataset age. Say goodbye to hammering F5!
• Live Lightning Strikes: new lightning strikes are displayed instantly, giving you an even better feeling for the cloud formation's intensity, trajectory and speed.
• Push Notifications: get notified about incoming rain up to 60 minutes in advance. Works in any modern browser and on iOS.
• Dark Mode: great for HUD-like displays and general night time usage.
• Progressive Web App: responsive, connectivity independent and app-like. Add a shortcut to your iOS or Android Home Screen to use meteocool in "app mode".
• iOS App: a native iOS app provides battery-efficient background location services to provide accurate rain notifications without any user interaction.

Use docker-compose (see below) for the backend. Run make dev to run the development build (the first one might take a while).

Use make dev devrestart to build and also start all containers on your local system. After that, go to https://127.0.0.1:8040 to access your development system.

• Production build: make prod
• Use feature branches!
• docker-compose MUST be executed in the root-directory of the repository! Otherwise bind mounts for config files will not work and no error will be reported.
• When the color mapping for dbZ-values (pixels) is changed, the legend needs to be regenerated. Because this happens very rarely, the script for that isn't dockerized. Use make legend inside backend/dwd/ to regenerate the legend PNG.
• The database is initialized when the first entry is generated. Sadly this causes the push backend to hang until backend/app provides a first entry. As a work around, create a notification request via the web UI after the first startup. The databse is persistently kept on a docker volume.

Makefile targets in backend/dwd/:

• make mbtiles: create PNG + tiles in tmp/
• make update: fetch current radar date from DWD
• make update mbtiles: both operations together

For frontend development, use yarn && yarn start inside the frontend/ directory. This will compile the src/index.js application and start a development webserver on localhost. Note that for a complete local development setup you also need the other containers.

the way to go. 2018.

install docker-compose and use make dev. For development purposes, use the docker-compose-dev.yml file.

Release builds can be built using make prod or manually:

• docker-compose build
• docker-compose up (debug)
• docker-compose up -d (background)
