poll-observer

Intro

poll-observer instruments XMLHttpRequest, setTimeout, setInterval, etc. to identify and report common poll loop patterns from the browser.

Usage

var pollObserver = require('poll-observer')
var shouldDisconnect = false
pollObserver.observe(function(data) {
  var entries = data.getEntries()
  entries.forEach(function(entry) {
    console.info('poll entry:', data.pollId, entry.type, entry.url)
  })

  if (shouldDisconnect) {
    pollObserver.disconnect()
  }
})

Example output

poll entry: 0 poll http://mysite.com/data.json?reqIndex=0
poll entry: 0 poll http://mysite.com/data.json?reqIndex=1

.... sometime later, maybe ...
poll entry: 0 poll http://mysite.com/data.json?reqIndex=2

.... and even later, maybe ...
poll entry: 0 poll http://mysite.com/data.json?reqIndex=3
