Run nodemon and gulp serve together in a single command

start.sh

#!/bin/bash

PIDFILE="nodemon.pid"
SERVER_PATH="server/index.js"
CLIENT_TASK="gulp serve"

if [ ! -f $PIDFILE ]; then
  nohup nodemon $SERVER_PATH >/dev/null 2>&1 &
  PID=$!
  echo $PID > $PIDFILE
  echo "nodemon running as pid $PID"
  $CLIENT_TASK
  rm $PIDFILE
else
  PID=`cat $PIDFILE`
  echo "nodemon already running as pid $PID"
fi

This is useful for running a node backend and a client-side app (using something like BrowserSync) from a single command. You can point npm start at this bash script and happy days. Killing the task with ctrl-c will terminate the nodemon process as well.
