# Project lives in $HOME/projects/pi-web-chat — override with `WorkingDirectory=`
# in an override unit or in install-service.sh if you keep it elsewhere.
# We don't hardcode the path here so the file is portable across machines /
# forks; the install script substitutes it at install time.
WorkingDirectory=%h/projects/pi-web-chat

# Same reasoning for the Node binary — prefer what Node.js EnvFile says if
# the user has nvm/fnm; otherwise rely on /usr/bin/node being on PATH.
ExecStart=/usr/bin/env node server.js

# Allow overriding via environment files / drop-ins without editing this
# unit. PORT, PI_BIN, PI_SESSIONS_DIR etc. are honored by server.js.
