Answer 1

The error message says it all, the middleware is no longer native available on express and should be installed separately. I believe you are indicating due to the logger usage here app.use(express.logger('dev')), what you can do is use a separate logger.

Example with express 4:

Install

npm install morgan

Use

var logger = require('morgan');
app.use(logger('dev'));
