Socket logging

The module also contains an extremely simple socket logging function:

var io = require('socket.io').listen(server);
io.on('connect', socket => {
	socket.on('something', require('express-log-url').socket);
	socket.on('something', ()=> ...Actually do work...);
})

Manual logging

The module supports an object containing optional fields which will be output as if it were a fresh server request

var logger = require('express-log-url');

// Simulate a GET request
logger.log({method: 'GET', code: 200, path: '/', responseTime: 10});

// Simulate a POST request with additional fields
logger.log({method: 'POST', code: 400, path: '/some/post', responseTime: 20, info: 'Lack of widgets'});

Field	Description
indent	Indentation to use. Is commonly a number of spaces
method	Short (ideally no more than 5 characters) method to show
code	The status code returned by the server
responseTime	The time (in milliseconds) the server took to respond
info	Additional information to log against the request
