Before using the library, you need to import it.
import { Sticker, createSticker, StickerTypes } from 'wa-sticker-formatter' // ES6
// const { Sticker, createSticker, StickerTypes } = require('wa-sticker-formatter') // CommonJSconst sticker = new Sticker(image, {
pack: 'My Pack', // The pack name
author: 'Me', // The author name
type: StickerTypes.FULL, // The sticker type
categories: ['🤩', '🎉'], // The sticker category
id: '12345', // The sticker id
quality: 50, // The quality of the output file
background: '#000000' // The sticker background color (only for full stickers)
})
const buffer = await sticker.toBuffer() // convert to buffer
// or save to file
await sticker.toFile('sticker.webp')
// or get Baileys-MD Compatible Object
conn.sendMessage(jid, await sticker.toMessage())You can also chain methods like this:
const buffer = await new Sticker(image)
.setPack('My Pack')
.setAuthor('Me')
.setType(StickerTypes.FULL)
.setCategories(['🤩', '🎉'])
.setId('12345')
.setBackground('#000000')
.setQuality(50)
.toBuffer()The image (first parameter) can be a Buffer, URL, SVG string, or File path.
const sticker = new Sticker(`

`, { author: 'W3' })const buffer = await createSticker(buffer, options) // same params as the constructor

}Here's some basic information about WhatsApp Sticker Metadata.
In WhatsApp, stickers have their own metadata embedded in the WebP file as They hold info like the author, the title or pack name and the category.
The text on bold is the pack title and the rest is the author. This is actually Exif Metadata embedded in the WebP file.
This is an array of Emojis. Learn More
To extract the metadata from the WebP file, you can use the extractMetadata() function.
import { extractMetadata, Sticker } from 'wa-sticker-formatter'
import { readFileSync } from 'fs'
const sticker = readFileSync('sticker.webp')
let metadata = await extractMetadata(sticker) // { emojis: [], 'sticker-pack-id': '', 'sticker-pack-name': '', 'sticker-author-name': '' }
// or use the static method from the Sticker class
metadata = await Sticker.extractMetadata(sticker)Thanks for using Wa-Sticker-Formatter!
