itch.io Bundle Claim

Description

This is a simple script, which claims all of the bundle downloads for your account so you don't have to manually click the 'Download' button on each item.

Directions

1. Login to itch.io
2. Browse to the bundle page
3. Open the developer console (typically F12, but depends on browser)
   • Choose the "Console" tab
4. Run the script
   • Copy the entire contents of script.js
   • Paste it into the console
   • Press enter
   • Wait for the console message of 'finished' to appear, with the count of downloads claimed
5. Go to the next bundle page, and run again

script.js

(async () => {
  // Find all buttons on the page that have the claim value, e.g., the
  // button you'd normally click to claim the download.
  const buttons = Array.from(document.getElementsByTagName('button'))
    .filter(btn => btn.value === 'claim');

  const sleep = (ms) => new Promise(resolve => setTimeout(resolve, ms));

  const claim = async (btn) => {
    // jQuery is still useful!
    const form = $(btn.parentElement).serialize()
      + '&action=claim';
    
    // Send an HTTP POST message to the current URL in the browser.
    await fetch(window.location, {
      method: 'POST',
      credentials: 'include',
      headers: {
        // Mimic all of the headers that are sent normally when you click.

      },
      body: form,
      redirect: 'manual'
    });
  };

  // Claim each of the downloads
  for (const button of buttons) {
    await claim(button);
    // Be kind to the itch.io servers
    await sleep(2000);
  }
  console.log('finished', { count: buttons.length });
})();
