Technically this module does not allow you to do this, because it's entire purpose is to write one standard access.log line per request, but technically you can hack this together, based on #24 (comment) :
// Define your morgan logger to log JSON to your client
// The object here takes your keys and strings that use
// the morgan token format
app.use(logger(format({
response_time: ':response-time',
remote_addr: ':remote-addr',
remote_user: ':remote-user',
status: ':status',
url: ':url',
// etc.; any non-standard tokens you would have to implement
})));
function format(obj) {
var keys = Object.keys(obj)
var token = /^:([-\w]{2,})(?:\[([^\]]+)\])?$/
return function (tokens, req, res) {
var data = {}
for (var i = 0; i < keys.length; i++) {
var val = token.exec(obj[key])
data[key] = val !== null
? tokens[val[1]](req, res, val[2])
: obj[key]
}
console.log(JSON.stringify(data, null, 4))
}
}from morgan.

Trying:
app.use(morgan(rethinkdbLog({
id: ':id',
date: ':date[iso]',
http_version: ':http-version',
method: ':method',
url: ':url',
status: ':status',
response_time: ':response-time',
remote_user: ':remote-user',
remote_addr: ':remote-addr',
user_agent: ':user-agent',
referrer: ':referrer'
})));
function rethinkdbLog(obj) {
var keys = Object.keys(obj);
var token = /^:([-\w]{2,})(?:\[([^\]]+)\])?$/;
return function (tokens, req, res) {
var data = {};
for (var i = 0; i < keys.length; i++) {
var val = token.exec(obj[key]);
data[key] = val !== null ? tokens[val[1]](req, res, val[2]) : obj[key];
}
r.table('requests').insert(data, { returnChanges: true }).run(rethinkdbConnection, function(error, result) {
if(error) {
handleError(res, error);
}
else if (result.inserted !== 1) {
handleError(res, new Error("Failed to insert request log document into RethinkDB."));
} else {
next();
}
});
};
}
Getting:
var val = token.exec(obj[key]);
^
ReferenceError: key is not defined

Oops, my bad. You need to add
var key = keys[i]
as the first line in the for loop.

Thanks worked great. One thing I noticed is that the field response_time comes back as a string instead of a number. Is this intentional?
{ id: 'c1dabb4e-03c3-4ec3-a127-b11a0b3f936a',
date: '2015-05-31T21:49:18.687Z',
http_version: '1.1',
method: 'GET',
url: '/',
status: 200,
response_time: '10.509',
remote_user: '-',
remote_addr: '::ffff:127.0.0.1',
user_agent: 'curl/7.37.1' }

Because this module is intended for writing log lines, yes, all tokens come back as strings--you would have to add Number() or parseFloat() to your code if you wanted them as numbers.

Yes, status code is coming back as a number, I know. If you wanted to know the main reason response time comes back as a string, it's because the response time can be 0ms, as as a number, 0 is falsy, but as a string, '0' is truthy, so 0 doesn't get translated to -.
