express-after-end

express middleware for taking action after a request has ended

Quickstart

$ npm install --save express-after-end

Then, in your application:

var express = require('express');
var afterEnd = require('express-after-end')

var app = express()

app.use(function (req, res, next) {
  res.locals.reqStartTime = new Date()
  console.log('< %s %s', req.method, req.originalUrl)
  next()
})

app.use(afterEnd(function (req, res) {
  var responseTime = new Date() - res.locals.reqStartTime
  console.log('> %s %s %d %d', req.method, req.originalUrl, res.statusCode, responseTime)
}))

app.use(function (req, res) {
  res.status(200).send('OK')
})

app.listen(80);

api

afterEnd(fn, [before=false])

fn is the function to call on the request end event; it is called using with the following signature:

function fn (req, res) {
  // ...
}

before determines whether fn will be invoked before the next end handler or after. The default is after, resulting in FIFO ordering of invokations.
