Teikei

Teikei is a web application and API that maps community-supported agriculture (CSA) initiatives in Germany, Switzerland and Austria using crowdsourced data. It provides a public map frontend, a REST API backend, and an admin interface for moderators and maintainers.

Key Features

• Public map Single Page Application built with React and Redux, using Leaflet for map display
• JSON REST API implemented with Node and Feathers on an Express server
• Data persisted in PostgreSQL; includes database seed scripts and test data for development
• Admin dashboard for content moderation built with crudl.io and separate admin API endpoints
• Monorepo structure with npm workspaces and Lerna, plus top-level scripts to run all modules together
• Development tooling supports Docker-based local databases, environment configuration via .env, and job scheduling using node-schedule
• Input validation and client/server integration using joi and feathers-client

Use Cases

• Publish and maintain a crowd-sourced directory of community-supported agriculture sites for a region
• Provide a browsable and searchable public map for volunteers, consumers, and organizers
• Allow administrators and moderators to curate listings and manage site data through an admin UI

Limitations and Considerations

• Geographic scope and dataset are focused on Germany, Switzerland and Austria; broader coverage requires additional contributions
• Advanced spatial queries or mapping optimizations may require adding PostGIS or other geospatial extensions if not already configured
• Scalability and high-traffic deployment will depend on API/DB tuning; the default stack is optimized for community-scale deployments rather than very large, high-load services

Teikei is practical for organizations or communities that want an open, self-hosted directory and map for CSA projects. It combines a modern JavaScript frontend, a Node-based API, and a simple admin workflow to make crowdsourced location data easy to publish and manage.
