# systemd unit for the chess-io node app — /etc/systemd/system/chess-io.service
# ============================================================================
#
# Runs the app as a long-lived service behind Apache (see apache-chess.conf.example).
# Adjust User/Group and WorkingDirectory to match where the repo is checked out
# on the server, then:
#
#     sudo cp deploy/chess-io.service.example /etc/systemd/system/chess-io.service
#     sudo systemctl daemon-reload
#     sudo systemctl enable --now chess-io
#     systemctl status chess-io
#     journalctl -u chess-io -f          # logs (boot/config + game counts)
#
# On deploy of new code: git pull && npm ci && sudo systemctl restart chess-io
