# Put this in your deployment user's home directory. Make sure nvm is installed for that user.
# Execute this file from the directory where the pm2 app package.json resides.
# Example: ssh user@server "cd /path/to/app/root && /home/user/deploy_pm2_app.sh pm2_app_name"

NVM_DIR=/home/username/.nvm

[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"  # This loads nvm

## Run whatever you need to do to prepare for restart:
## git fetch && git rebase
## npm ci

if [ -z "$1" ]; then
  echo "Please supply a pm2 app name.";
else
  pm2 restart $1
