Express Latency Header Middleware

This middleware adds two headers to the response.

• x-request-received is set by the server with the timestamp of when the request was received
• x-response-sent is set by the server with the timestamp of when the response was sent

More information on why to add these headers.

Example

npm install express-latency-headers --save

var express = require('express')
var latencyHeaders = require('express-latency-headers')
var app = express()

app.use(latencyHeaders())

app.use(function(req, res, next) {
  setTimeout(function(){
    res.send('Hello World!')
  },1000)
})

var server = app.listen(3000)
