前言

    相信大家在开发Node.js应用的的时候，都遇到了一个挺让人烦恼的事情，就是每次即使只是小小的修改了一下子代码，那么也得再重新Crtl+c退出来重启，不像在开发php，java等web项目的时候，修改了项目代码，服务器都会自动重启，让我们的改动生效，好在有大神开发了自动重启的工具——nodemon！推荐给大家

C:\Users\92816\Desktop>nodemon -h
  Usage: nodemon [options] [script.js] [args]

  Options:

  -e, --ext ................ extensions to look for, ie. js,jade,hbs.
  -x, --exec app ........... execute script with "app", ie. -x "python -v".
  -w, --watch dir........... watch directory "dir" or files. use once for
                             each directory or file to watch.
  -i, --ignore ............. ignore specific files or directories.
  -q, --quiet .............. minimise nodemon messages to start/stop only.
  -V, --verbose ............ show detail on what is causing restarts.
  -I, --no-stdin ........... don't try to read from stdin.
  -C, --on-change-only ..... execute script on change only, not startup
  --no-colors .............. disable color output
  -d, --delay n ............ debounce restart for "n" seconds.
  --exitcrash .............. exit on crash, allows use of nodemon with daemon
                             tools like forever.js.
  -v, --version ............ current nodemon version.
  -h, --help ............... you're looking at it.
  --help <topic> ........... help on a specific feature. Try "--help topics".
  -- <your args> ........... to tell nodemon stop slurping arguments.

  Note: if the script is omitted, nodemon will try to read "main" from
  package.json and without a nodemon.json, nodemon will monitor .js, .coffee,
  and .litcoffee by default.

  To learn more about nodemon.json config: nodemon --help config
  See also the sample: https://github.com/remy/nodemon/wiki/Sample-nodemon.json

  Examples:

  $ nodemon server.js
  $ nodemon -w ../foo server.js apparg1 apparg2
  $ PORT=8000 nodemon --debug-brk server.js
  $ nodemon --exec python app.py
  $ nodemon --exec "make build" -e "styl hbs"
  $ nodemon app.js -- -v
