# Houserules — DEV stack with hot reload.
#
# Start:  docker compose -f docker-compose.dev.yml up
# Stop:   docker compose -f docker-compose.dev.yml down
#
#   web         → Vite dev server on http://localhost:5173 (HMR enabled)
#   server      → Bun WS on ws://localhost:7357/ws, --hot on file change
#   rete-watch  → tsup --watch keeps packages/rete/dist fresh so that
#                 changes to rete trigger HMR in the chess app (chess
#                 resolves @paratype/rete via its dist/ "import" entry)
#
# How the volume layout works:
#   - The whole repo is bind-mounted at /app so source edits on the host
#     are seen instantly by the containers.
#   - Each package's `node_modules/` is an anonymous volume, which
#     SHADOWS the host directory. That keeps the container's
#     bun-installed deps (Linux binaries, correct symlink targets)
#     from being clobbered by whatever your host has installed.
