Grab and print all captions from your Instagram feed.

instagram-caption-scrape.js

// A bunch of tools exist for downloading Instagram photos
// (eg. chrome.google.com/webstore/detail/olkpikmlhoaojbbmmpejnimiglejmboe)
// but not as many grab your captions. This is quick and dirty, in the spirit of

// In your browser of choice, open up the Web Console and paste in the following.
// You might need to change some `querySelector` calls to match the Instagram web
// client's current markup.

// Fragile! Based on a generated classname. Replace this with whatever selector
// will match the main image container.
var mainContainer = document.querySelector('._havey');

// But also, this is all super fragile. It relies on very specific element and
// sibling placement. It'll probably need some massaging to match the current
// document setup.

  var perhapsEvenMoarImgs = imgs.concat(Array
    .from(mainContainer.querySelectorAll('img'))
    .filter(img => imgs.indexOf(img) === -1)
