title: When to initialize mysql connections in node
body: <p>I'm trying to figure out what the best time to actually initialize connections for mysql in node is.</p>
  
  <p>Am I supposed to create a pool of connections and then set them to some global so that all my models have access to the pool? Or am I supposed to initialize connections whenever I'm doing queries?(Seems bad).</p>
  
  <p>I'm sure there's some "proper" way to do it, but I'm not really certain what the best way is.</p>
