JS code to share all items in a poshmark closet to followers and all available events

poshmark-share

const clickDelta = 4000; // ms delay between clicks
const cycleDelta = clickDelta * 100; // ms delay between share cycles

const clickLinks = (el) => {
  el.click();

  // set a short timeout so there's time to load in the active parties/render the modal
  setTimeout(() => {
    document
      .querySelectorAll("[data-et-name='share_poshmark']")
      .forEach((el) => el.click());
  }, 200);
};

const notSold = (el) => {
  return (
    el
      .closest(".card")
      .querySelectorAll(".sold-tag,.sold-out-tag,.not-for-sale-tag")
      .length === 0
  );
};

// check if there are any sold tags on page
const hasSold = () => document.querySelectorAll(".sold-tag,.sold-out-tag").length > 0

// one screen height from the bottom
const nearBottom = () => document.body.scrollHeight - window.innerHeight;

const scrollToBottomAndWait = () => {
  if (!hasSold()) {
    window.scrollTo(0, nearBottom());
  }

  return new Promise((resolve) => {
    setTimeout(() => {
      const isScrolledToBottom =
        window.innerHeight + window.scrollY >= nearBottom();
      if (!isScrolledToBottom && !hasSold()) {
        resolve(scrollToBottomAndWait());
      } else {
        resolve();
      }
    }, 2000);
  });
};

const share = async () => {
  await scrollToBottomAndWait();

  let timeout = 0;
  const doShare = (el) => {
    if (notSold(el)) {
      // register link clicking
      setTimeout(() => clickLinks(el), timeout);

      // make sure next registered click comes after
      timeout += clickDelta;
    }
  };

  const shareLinks = Array.from(document.querySelectorAll("[data-et-name=share]")).reverse();
  shareLinks.forEach(doShare);
};

share();
setInterval(share, cycleDelta);

@SeanMcGrath Thanks for sharing this code! I have a question about the last 2 lines:

 share();
 setInterval(share, cycleDelta);

I'm presuming that cycleDelta get incremented after it's first declared, so that it adds up to the total amount of time it takes to get through one cycle. But I don't understand how. Can you explain? (I'm new to JavaScript, so apologies if this is a silly question.)

cycleDelta is the interval between runs of the share function. the value of cycleDelta itself is constant. setInterval(x, y) runs the specified function x every y milliseconds.

updated to incorporate @ianmcilwraith 's changes (thanks!) and also stop scrolling down the page once sold items are found.
