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
`sh
npm i -S hapi-response-time
`

- and register it with the hapi's server instance:
`js
await server.register(require('hapi-response-time'));
`

Example:

`sh
npm i -S hapi hapi-response-time
`

`js
'use strict';

const Hapi = require('@hapi/hapi');

const init = async () => {

const server = Hapi.server({
port: process.env.PORT || 3000,
host: 'localhost'
});

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

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

await server.start();
console.log('Server running on %s', server.info.uri);
};

process.on('unhandledRejection', (err) => {

console.log(err);
process.exit(1);
});

init();
