title: Express suddenly doesn't include any middleware
body: <p>I've been using Node.js and Express for a while perfectly fine for a web application, and suddenly today I keep getting errors about how "Most middleware (like bodyParser) is no longer bundled with Express and must be installed separately"</p>
  
  <p>This is happening because I upgraded npm to 4.0.2 and there is a link in the error dialog documenting how to install and use the new middleware.</p>

  <p>Edit: I understand how to run with the new versions of express, and how to install the new middleware. I think it would be useful to put down on record how exactly to revert back to the old version of express/npm so that people can if they want to.</p>
