API

Constructor

The HTTPTiming constructor

• options The constructor options
  • options.max The max time(ms), use for the time line bar, default is 10 * 1000
  • options.size The cache size, default is 10

const HTTPTiming = require('http-timing');
const httpTiming = new HTTPTiming({
  max: 5 * 1000,
  size: 5,
});

add

Add the data to timing view, return function to change the value of data

• data The setting of http timing
  • data.url The http request url
  • data.method The http request method
  • data.status The http response status
  • data.use The http response time
  • data.serverTiming The http server timing

const HTTPTiming = require('http-timing');
const httpTiming = new HTTPTiming();
const set = httpTiming.add({
  method: 'GET',
  url: '/users/me',
  status: 200,
  use: 3000,
  serverTiming: 'A;dur=2521.46147;desc="/users/me",B;dur=102.022688;desc="getUser",C;dur=33.468153;desc="mongodb:get",D;dur=54.064163;desc="validate:user"',
});
set('use', 5000);
set({
  use: 5000,
});

get

Get the timing by index

• index the timing index

const HTTPTiming = require('http-timing');
const httpTiming = new HTTPTiming();
httpTiming.add({
  method: 'GET',
  url: '/users/me',
  status: 200,
  use: 3000,
  serverTiming: 'A;dur=2521.46147;desc="/users/me",B;dur=102.022688;desc"getUser",C;dur=33.468153;desc"mongodb:get",D;dur=54.064163;desc="validate:user"',
});
console.info(httpTiming.get(0));

length

Get the cache length

const HTTPTiming = require('http-timing');
const httpTiming = new HTTPTiming();
// 0
console.info(httpTiming.length);

empty

Remove all cache

const HTTPTiming = require('http-timing');
const httpTiming = new HTTPTiming();
httpTiming.add({
  method: 'GET',
  url: '/users/me',
  status: 200,
  use: 3000,
  serverTiming: 'A;dur=2521.46147;desc="/users/me",B;dur=102.022688;desc="getUser",C;dur=33.468153;desc="mongodb:get",D;dur=54.064163;desc="validate:user"',
});
// 1
console.info(httpTiming.length)
httpTiming.empty();
// 0
console.info(httpTiming.length)

toHTML

Get the html of http timing

const HTTPTiming = require('http-timing');
const httpTiming = new HTTPTiming();
httpTiming.add({
  method: 'GET',
  url: '/users/me',
  status: 200,
  use: 3000,
  serverTiming: 'A;dur=2521.46147;desc="/users/me",B;dur=102.022688;desc="getUser",C;dur=33.468153;desc="mongodb:get",D;dur=54.064163;desc="validate:user"',
});
const html = httpTiming.toHTML();
console.info(html);
