The Biergarten App

The Biergarten App is a full-stack directory and discovery platform for breweries. It features a robust user authentication system, a searchable database of brewery locations, and a custom offline data-generation pipeline that uses LLMs (Llama.cpp) and Wikipedia to synthesize realistic seed data.

It features:

• A .NET backend (Web API + database migrations/seed) under web/backend/
• A server-rendered React website (React Router + Vite) under web/frontend/
• A C++20 “pipeline” CLI for generating seed data under tooling/pipeline/

Specialized documentation (setup, architecture, docker, testing, diagrams, and pipeline notes) lives under docs/.
