Shop alone! Tell others when you go and save lifes by avoiding queues & crowds in times of Covid-19.
Wouldn't it be awesome to know when and where everyone else is shopping and simply go somewhere else? Since such behaviour is mandatory to #flattenthecurve of corona-virus infections, shopalone tries to solve this issue.
With shopalone, users can enter when and where they are going for their groceries such that others can decide where to go based on the aggregated data. All this is possible without sacrificing privacy of individuals - User accounts are not necessary and geodata is imported from OpenStreetMap.
The 48 hours of the #wirvsvirus hackathon did not suffice to implement the full web service, so only a prototype backend serving a small REST-API could be realized. A minimal web frontend was added eventually.
- Download some OpenStreetMap data as PBF file for your region, e.g. from here
- Install Osmosis and setup a PostGIS database as lined out in the documentation. The
postgis/postgisDocker image provides an easy way to get a PostGIS database running quickly. - Clone this repository:
https://github.com/jvytee/shopalone.git - Import data from your downloaded file into the database by executing
./import_osm.sh <PBF path> <PostgreSQL host> <PostgreSQL schema> - Install shopalone and dependencies:
pip install . - Set shopalone as Flask app:
export FLASK_APP=shopalone.main:app - Initialize the database:
flask init-db
For development and debugging purposes, the service can be started by flask run.
In a production environment however, the service should be run with an application server such as Gunicorn.
For a containerized setup, the provided Dockerfile and docker-compose.yml can serve as a reference.
All API endpoints return JSON data, the web frontend is plain HTML.
