Quick hack to scrape posts from facebook groups

If you ever find yourself needing to copy text from facebook groups (for fear of graph auth) for market research or data viz, I wrote a super simple script that you can paste into your console after having visited the group page.

var text = ''
var imgUrls = ''

var scroller = function(by) {
  window.scrollBy(0, by)
}

var logText = function() {
  document.querySelectorAll('.userContent p').forEach(item => {
    text = `${text}\n\n${item.innerText}`
  })

 document.querySelectorAll('img.img').forEach(item => {
    imgUrls = `${imgUrls}\n\n${item.getAttribute('src').split('?')[0]}`
  })

  console.log(text)
  console.log(imgUrls)
}

var startInterval = function(scrollBy, speed, endby) {
  var interval = setInterval(() => {
    this.scroller(scrollBy)
  }, speed*1000)

  setTimeout(() => {
    clearInterval(interval)
    logText()
  }, endby*1000)
}

startInterval(5000, 0.5, 30) // will log the text after 30 seconds. Increase to load more
