http-performance

http-performance

I use httpstat to test my rest api's performance and then I want to write a module to get the performance of http.

The moudle can get the request and response of http, including dns, method, url and so on.

API

// please require the module first
const httpPerf = require('http-performance');
const http = require('http');
httpPerf.on('stats', (stats) => {
/*  { type: 'request',
  dns: { ip: '14.215.177.38', addressType: 4 },
  requesting: 0,
  method: 'GET',
  host: 'www.baidu.com',
  url: '/',
  status: 200,
  bytes: 15358,
  timing: { socket: 9, dns: 2, tcp: 6, processing: 13, transfer: 5, all: 35 } }
*/
  console.info(stats);
});
http.get('http://www.baidu.com/');

// please require the module first
const httpPerf = require('http-performance');
const http = require('http');
const express = require('express');
httpPerf.on('stats', (stats) => {
  if (stats.type !== 'response') {
    return;
  }
/* { type: 'response',
  method: 'GET',
  timing: { all: 1013, socket: 0 },
  status: 200,
  url: '/',
  bytes: 60,
  responsing: 0 }
*/
  console.info(stats);
});
const app = express();
app.use((req, res, next) => setTimeout(next, 1000));
app.use((req, res) => {
  res.json({
    message: 'hello world',
  });
});

const server = app.listen();
const url = `http://127.0.0.1:${server.address().port}`;
http.get(url);

disable/enable

Diable or enable the http stats type, default is enabled.
