Background Mode

const sock = makeWASocket({ markOnlineOnConnect: false })

NEW: Channel, Group & Contact Tracker ⚡

Cek Semua Channel yang Diikuti

const channels = await sock.getFollowedChannels()
// → [{ jid, name, description, subscribers, role, state, invite }, ...]

for (const ch of channels) {
  console.log(`📡 ${ch.name} — ${ch.subscribers} subscribers`)
}

Cek Semua Group yang Diikuti

// Cepat (tanpa profile pic)
const groups = await sock.getJoinedGroups()
// → [{ id, subject, participants, ... }, ...]

// Lengkap dengan foto profil
const groupsFull = await sock.getJoinedGroups(true)
// → [{ id, subject, participants, profilePic, ... }, ...]

for (const g of groups) {
  console.log(`👥 ${g.subject} — ${g.participants?.length} member`)
}

Cek Semua Kontak

const saved = contacts.filter(c => c.exists)
console.log(`📒 Total kontak tersimpan: ${saved.length}`)

NEW: Convert, Resize & Compress ⚡

Convert Image → Sticker WebP

// Dari buffer gambar biasa
const { buffer, metadata } = await sock.convertToSticker(imageBuffer, {
  packName:      "Pack Gue",
  packPublisher: "N4tzz",
  quality:       80,    // 1-100
  maxSize:       512,   // max px (default 512)
})
await sock.sendMessage(jid, { sticker: buffer, ...metadata })

// Atau langsung kirim setelah convert
const result = await sock.convertToSticker(imageBuffer, { packName: "Sticker", packPublisher: "Bot" })
await sock.sendStickerWithMetadata(jid, result.buffer, result.metadata)

Resize & Compress Image

// Resize ke max 800px, format JPEG, quality 75%
const compressed = await sock.convertMedia(imageBuffer, {
  maxSize: 800,
  format:  "jpeg",
  quality: 75,
})
await sock.sendImage(jid, compressed, "Foto sudah dikompress")

// Resize ke dimensi spesifik
const resized = await sock.convertMedia(imageBuffer, {
  width:   1280,
  height:  720,
  format:  "webp",
  quality: 85,
})

// Convert ke PNG
const png = await sock.convertMedia(imageBuffer, { format: "png", quality: 90 })

Catatan: Butuh sharp (recommended) atau jimp terinstall.

npm i sharp   # atau: npm i jimp

NEW: Sticker Pack Batch ⚡

Kirim Sticker Pack Sekaligus (Batch Parallel)

// sendStickerPack — sekarang batch paralel per 5, bukan 1-by-1
await sock.sendStickerPack(jid, [buf1, buf2, buf3, buf4, buf5], "Pack Gue", "N4tzz", {
  batchSize:  5,    // kirim 5 sekaligus per batch
  delayBatch: 500,  // delay 500ms antar batch
})

// sendStickerPackAlbum — batch lebih besar (max 10 per batch)
const results = await sock.sendStickerPackAlbum(jid, [buf1, buf2, buf3], "Pack Gue", "N4tzz", {
  batchSize:  10,
  delayBatch: 800,
})
console.log(results) // [{ success, msg? }, ...]

NEW: Document Pack ⚡

Kirim Banyak Dokumen Sekaligus

// Sequential dengan delay (default)
const results = await sock.sendDocumentPack(jid, [
  { buffer: pdfBuffer,  fileName: "laporan.pdf",   caption: "Ini laporannya" },
  { buffer: excelBuf,   fileName: "data.xlsx",      caption: "Data excel" },
  { url: "https://...", fileName: "manual.pdf" },
], {
  delayMs: 600,  // delay 600ms antar dokumen
})

// Kirim semua sekaligus (paralel)
const results = await sock.sendDocumentPack(jid, documents, { parallel: true })

console.log(results) // [{ success, msg? }, ...]

Auto Mime Detection — tidak perlu set mimetype manual. Deteksi otomatis dari extension: .pdf → application/pdf, .xlsx → spreadsheet, .apk → android package, dll.
