Response Time Plugin for HapiJS

This plugin will add following headers to each request. And the time represented is in the UNIX/Epoch time.

The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z).

x-req-start →1484305451729
x-res-end →1484305451738
x-response-time →9

• x-req-time: The time on which request is received on server
• x-res-end: The time before sending the response
• x-response-time: The difference between above two, i.e. the time taken by server to process the request before sending the response

To use this plugin:

• Install

npm i -S hapi-response-time

• and register it with the hapi's server instance:

await server.register(require('hapi-response-time'));

Example:

npm i -S hapi hapi-response-time

var Hapi = require('hapi');
var server = new Hapi.Server({
  port: process.env.PORT || 3000
});

await server.register(require('hapi-response-time'));

server.route([
  {
    method: 'GET',
    path: '/john',
    handler: function(req, h) {
      return h.response('Hello John!');
    }
  },{
    method: 'GET',
    path: '/timeout',
    handler: async function (request, h) {
      await (() => { return new Promise(resolve => setTimeout(resolve, 10000)); })();
      return h.response('Response after 10 seconds');
    }
  }
]);
