title: NodeJS+MySQL instead of PHP+MySQL. Is it ok?
body: <p>I've read about NodeJS but couldn't find its dis/advantages. Can i replace a PHP/MySQL application with NodeJS/MySQL? is it good idea?</p>
  
  <p>Please consider a PHP CMS. Can NodeJS do as well as PHP? Is NodeJS only suitable for some lightweight actions?</p>
  
  <p>If it is ok, which MySQL module is the best one?</p>
