StickerMessage Builder

StickerMessage constructs and sends WhatsApp stickers (image/webp) with custom EXIF metadata, including sticker pack names, author credits, and emoji categories.

It automatically handles conversion and dimension scaling for image inputs.

Basic Example

import { StickerMessage } from 'leaves-guardian';

const sticker = new StickerMessage(client)
  .setSource('https://example.com/mascot.png')
  .setPackName('Roxy Bot Official Pack')
  .setAuthor('Royal Engine Studio')
  .setCategories(['🍃', '🤖']);

await client.sendMessage(msg.chat.id, sticker);

Static EXIF Generator

If you are generating raw WebP stickers independently, you can use the static StickerMessage.createExif() utility to produce raw EXIF Buffer chunks:

const exifBuffer = StickerMessage.createExif(
  'My Pack',
  'Author Name',
  ['🔥', '✨']
);
