connect-requestid

This package is useful for correlating your log messages across multiple requests (if you emit multiple log entries for each request).

HOWTO

Adds this to your .use configuration block.

app.use(require('connect-requestid'))

And that's it! :-)

Access the request id object with request.id like this:

app.get('/', function(req, resp) {
  resp.send('hello request #' + req.id);
});

GENERATOR

The id is generated from the require('connect-requestid').generator function. This function will by default uses the node-uuid module to generates 16 bytes of a unique identifier each time it is called.

You can replace this function with your own custom implementation with the signature generator(callback) and calls the callback function with the standard callback(e, string) to return the generated id.
