Is MySQL a common choice with Node.js? Don't see many people talking about SQL and Node.js. Anyone using this combo got something to say about their experience with it?
Hard to say if it's a common choice. I've had few projects where Node.JS was the choice of backend, and MySQL was the database, because our frontend was PHP/static HTML/CSS/JS stuff. DB is not really important. Node.JS shines on the backend, and it doesn't really matter to what it talks to. MySQL can be decently fast, but you can as well use Node.JS solely with, say, Riak or Mongo, or just Redis?
In this "crud-bones" project I am use Redis as a cache layer, but you can use it as "storage" as well...
