A script to auto-select the star emoji for all stickers when importing them to Signal

autoEmojiSignal.js

// Delay function
const delay = ms => new Promise(res => setTimeout(res, ms));
// Delay between clicks (seconds)
delayBetweenClicks = .1;

// Loop for all the stickers 
stickers = document.getElementsByClassName('lCzvEVovrfFcZaKyf3ZOA');
for (i=0; i<stickers.length; i++){
    // Clicking each emoji element for each sticker
    stickers[i].getElementsByClassName('_2S1Fkez4JWbv9-1wbe5aeH')[0].click();
    // Waiting
    await delay(delayBetweenClicks * 1000);
    // Scrolling to make the star visible
    document.querySelector("body > div:nth-child(8) > div > div > div:nth-child(1) > div").scrollBy(0, 4500);
    // Waiting
    await delay(delayBetweenClicks * 1000);
    // Clicking the star emoji
    document.querySelector('[title="star"]').click();
    // Waiting
    await delay(delayBetweenClicks * 1000);
    // logging
    console.log(i);
}

Updated version of this for 2025. Seems like some of the classes have changed slightly:

// Delay function
const delay = ms => new Promise(res => setTimeout(res, ms));
// Delay between clicks (seconds)
delayBetweenClicks = .1;

// Loop for all the stickers
stickers = document.getElementsByClassName('_container_7xrn4_1');
for (i=0; i<stickers.length; i++){
// Clicking each emoji element for each sticker
stickers[i].getElementsByClassName('_emoji-button_7xrn4_133')[0].click();
// Waiting
await delay(delayBetweenClicks * 1000);
// Clicking the star emoji
document.querySelector('[aria-label="star"]').click();
// Waiting
await delay(delayBetweenClicks * 1000);
// logging
console.log(i);
}
