Batch download emojis from any Discord server.

discord-batch-emoji-downloader.js

// based on peterthehan's gist - with updated scraping logic and per-emote logging
// -------------------------------------------------------------------------------
// 0. Open Discord's web client
// 1. Visit the server whose emojis you want
// 2. Open the emoji picker UI and keep it open
// 3. Minimize the page's zoom so that as many emojis load into the picker as possible
// 4. Open the browser's DevTools (press F12) > Elements tab
// 5. Use the element picker tool to select the server's emoji list header
// 6. Find the section that highlights the emojis you want when hovering over the element "<div class="categorySection_.."
// 7. Right click the element and Copy > Copy Element
// 8. Paste the element into "file.txt"
// 9. Run this script at the same location as "file.txt" to download all the emojis.

// Use a sensible sleep value so as not to rate-limit yourself
// The script relies on scraping so the regexp/logic may become outdated
