docker-compose.yml

# Full local development stack for the Tagg@d backend.
#
# Quick start:
#   cp backend/.env.example backend/.env
#   docker-compose up
#
# This brings up Postgres, Redis and the backend API with hot reload
# (nodemon + a bind mount of ./backend). Database migrations run
# automatically on backend startup (see backend/server.js).
#
# Bull Board (the queue admin UI) is served by the backend process itself at
# /admin/running-queues — it's exposed on its own host port (3001) below in
# addition to the main API port (3000) purely for convenience, since it's
# not a separate service in this codebase.
