node express 4 - how do I log successful requests?

In express 4, the package morgan is used for logging. Strangely, none of the built in modes seem to log successful requests - they only log error cases. I'm using it as middleware, like so:

app.use(morgan('dev'));

How can I get it to print all activity going through the server, including successful requests?

You need to be aware which middleware doesn't contain the next() invocation of the 'next' middleware.

For example, the 'serve-static' middleware does not invoke next() on success. It only invokes next() on certain error conditions. Therefore, in order to log success requests, you need to use() 'morgan' before 'serveStatic'

Turns out, I had to setup morgan before setting up my routes. Changing the order made everything work as expected

There is plenty of middleware available for logging. At a minimum, you can do something like this:

app.use(function log (req, res, next) {
  console.log([req.method, req.url].join(' '));
  next();
});

It's entirely up to you to decide how you want to handle this.

I usually don't bother as I typically run Nginx out in front of my application servers. If I need access logs, I just use its logs. If I need application logs for debugging, then that's what I get out of my Node.js servers.
