HTTP request logger middleware for node.js
Named after Dexter, a show you should not watch until completion.
var morgan = require('morgan')
Create a new morgan logger middleware function using the given format
and options
.
The format
argument may be a string of a predefined name (see below for the names),
a string of a format string, or a function that will produce a log entry.
Morgan accepts these properties in the options object.
Buffer duration before writing logs to the stream
, defaults to false
. When
set to true
, defaults to 1000 ms
.
Write log line on request instead of response. This means that a requests will be logged even if the server crashes, but data from the response (like the response code, content length, etc.) cannot be logged.
Function to determine if logging is skipped, defaults to false
. This function
will be called as skip(req, res)
.
// EXAMPLE: only log error responses
morgan('combined', {
skip: function (req, res) { return res.statusCode < 400 }
})
Output stream for writing log lines, defaults to process.stdout
.
There are various pre-defined formats provided:
Standard Apache combined log output.
:remote-addr - :remote-user [:date] ":method :url HTTP/:http-version" :status :res[content-length] ":referrer" ":user-agent"
Standard Apache common log output.
:remote-addr - :remote-user [:date] ":method :url HTTP/:http-version" :status :res[content-length]
Concise output colored by response status for development use. The :status
token will be colored red for server error codes, yellow for client error
codes, cyan for redirection codes, and uncolored for all other codes.
:method :url :status :response-time ms - :res[content-length]
Shorter than default, also including response time.
:remote-addr :remote-user :method :url HTTP/:http-version :status :res[content-length] - :response-time ms
The minimal output.
:method :url :status :res[content-length] - :response-time ms
:req[header]
ex: :req[Accept]
:res[header]
ex: :res[Content-Length]
:http-version
:response-time
:remote-addr
:remote-user
:date
:method
:url
:referrer
:user-agent
:status
To define a token, simply invoke morgan.token()
with the name and a callback function. The value returned is then available as “:type” in this case:
morgan.token('type', function(req, res){ return req.headers['content-type']; })
Simple app that will log all request in the Apache combined format to STDOUT
var express = require('express')
var morgan = require('morgan')
var app = express()
app.use(morgan('combined'))
app.get('/', function (req, res) {
res.send('hello, world!')
})
Simple app that will log all request in the Apache combined format to STDOUT
var finalhandler = require('finalhandler')
var http = require('http')
var morgan = require('morgan')
// create "middleware"
var logger = morgan('combined')
http.createServer(function (req, res) {
var done = finalhandler(req, res)
logger(req, res, function (err) {
if (err) return done(err)
// respond to request
res.setHeader('content-type', 'text/plain')
res.end('hello, world!')
})
})
Simple app that will log all request in the Apache combined format to the file “access.log”
var express = require('express')
var fs = require('fs')
var morgan = require('morgan')
var app = express()
// create a write stream (in append mode)
var accessLogStream = fs.createWriteStream(__dirname + '/access.log', {flags: 'a'})
// setup the logger
app.use(morgan('combined', {stream: accessLogStream}))
app.get('/', function (req, res) {
res.send('hello, world!')
})
