Zaileys review

Skill zeative/zaileys/plugins/zaileys-official/skills/zaileys-review

Use to REVIEW / AUDIT / CHECK existing zaileys (Node.js/TypeScript WhatsApp framework WhatsApp framework) code against best practices, anti-patterns, and ban-safety — triggers on "review my bot", "cek kode", "is this correct", "best practice?", or before shipping/deploying a zaileys bot. Covers BOTH providers: unofficial WhatsApp Web and the official Meta Cloud API (webhook signatures, template-gating, 24h window, idempotency).From its SKILL.md

zaileys — code review & audit

You audit existing zaileys code for anti-patterns, correctness, and ban-safety, then hand back actionable fixes. Import is always import { Client } from 'zaileys'. zaileys is a typed wrapper over Baileys; runs on Node 20+, Bun, Deno. Do NOT invent methods — verify every claim against the checklist below and the hub references in the assist skill (references/pitfalls.md, references/api.md, references/recipes.md) or the live full docs at https://zeative.github.io/zaileys/llms-full.txt.

Workflow

  1. Read the target. Read every file the user points at (and any local imports it pulls in). If they didn't name files, ask or scan the project's bot entrypoints (*.ts using new Client(). Note the entry, handlers, and any send loops.
  2. Scan against the REVIEW CHECKLIST below — anti-patterns, correctness, ban-safety. For each hit, capture severity, the exact location (file:line), and the concrete fix. Confirm method/option/event names against references/api.md before flagging.
  3. Report. Emit a findings table — severity | issue | location | fix — sorted high → low. Severity rubric:
    • high = ban-safety, data loss, or crashes (unthrottled mass send, leaked secrets, lost scheduled jobs, reply loops, calling a non-existent method).
    • medium = wrong-but-recoverable (wrong JID, ms-vs-seconds, unawaited key, missing qr handler, Node-floor regressions).
    • low = style / robustness nits.
  4. Corrected snippets. After the table, give a ❌ before → ✅ after TypeScript block for each high/medium finding, in house style (env-driven config, digitsOf normalization, msg.reply/msg.react inside handlers, terse, zaileys branding only).
  5. If the code is clean, say so explicitly and list what you verified.

Review checklist (highest-impact first)

Each item: ❌ bad → ✅ good + one-line WHY. Source of truth: references/pitfalls.md.

Ban-safety / data-loss / crashes — HIGH

Tight for-loop of sends → broadcast() + rate limit. (BAN RISK) ❌ for (const jid of jids) await client.send(jid).text('Promo!') ✅ await client.broadcast(jids, (b) => b.text('Promo!'), { rateLimitPerSec: 5 }) WHY: broadcast applies a token-bucket RateLimiter (default 5/s) and returns { sent, failed }; a raw loop fires unthrottled → spam flag → ban.

Hardcoded number/secrets → env, validated. ❌ const OWNER = '628123456789' / new Client({ phoneNumber: '628123456789' }) ✅ const OWNER = digitsOf(process.env['OWNER'] ?? ''); if (!OWNER) process.exit(1) WHY: hardcoding leaks identity into VCS and breaks multi-deploy; house style reads from process.env and validates before use.

Custom reconnect loop → built-in strategy. ❌ client.on('disconnect', () => client.connect()) ✅ new Client({ reconnect: { maxAttempts: 10, initialDelayMs: 1000, maxDelayMs: 30000 } }) WHY: the client owns reconnection (exponential backoff + jitter, skips fatal/logged-out reasons, clears auth when needed); calling connect() yourself races the internal timer. Read willReconnect on the disconnect event instead.

Assuming all stores persist scheduled jobs → only Convex does. ❌ new Client() then scheduleAt(...) — job LOST on restart (default MemoryMessageStore) ✅ new Client({ store: new ConvexMessageStore({ url }) }) then scheduleAt(...) WHY: scheduleAt survives restart only if the store implements saveScheduledJob/listScheduledJobs/deleteScheduledJob. Only the Convex adapter does; Memory/SQLite/Postgres/Redis keep jobs in-process only.

Ignoring isFromMe/ignoreMe → reply loop. ❌ new Client({ ignoreMe: false }) + an echo handler with no guard → infinite loop ✅ new Client() (ignoreMe defaults true); inside handler if (msg.isFromMe) return WHY: ignoreMe defaults true so the pipeline drops the bot's own messages; disabling it without guarding msg.isFromMe makes the bot answer its own echoes forever.

aiRich() does not exist → .text(md, { rich: true }). (crash) ❌ await client.send(jid).aiRich(markdown) — no such method ✅ await client.send(jid).text(markdown, { rich: true, title: '🤖 zaileys' }) WHY: there is no aiRich() content method; rich rendering (markdown/LaTeX/directives) is the rich: true flag on text(). TextOptions = { rich?, title?, footer?, sources? }.

v4.4 API usage — MEDIUM (HIGH if it crashes)

Many per-type handlers doing the same thing → message umbrella event. ❌ client.on('text', h); client.on('image', h); client.on('video', h) — same body, three handlers ✅ client.on('message', h) — one handler fires for every inbound message type WHY: message is the umbrella inbound event; collapse identical per-type handlers into it. Keep the per-type events (text, image, …) only when behavior genuinely differs by type.

Ad-hoc conversation key → ctx.staticId. ❌ const key = msg.roomId ?? msg.senderId to key memory/state — collides across room/sender combos ✅ const key = msg.staticId — stable hash(roomId|senderId), the canonical per-conversation key WHY: staticId uniquely identifies a sender within a room/group; use it for memory/state. Still use the real roomId/senderId JIDs as send targets — staticId is a hash, not a JID.

groupInvite().expiresAt in ms instead of SECONDS. ❌ .groupInvite({ ..., expiresAt: Date.now() + 86_400_000 }) ✅ .groupInvite({ ..., expiresAt: Math.floor(Date.now() / 1000) + 86400 }) WHY: expiresAt maps straight to WhatsApp's inviteExpiration (Unix seconds); passing ms yields a wildly future expiry. (Defaults to ~3 days if omitted.)

event() sent to a 1:1 DM → won't render. ❌ await client.send(userJid).event({ name: 'Meetup', ... }) — silently doesn't display in a DM ✅ send event() to a group/community JID ([email protected]); use a plain message for 1:1 WHY: event messages only render in groups/communities, not 1:1 chats.

product() without a Business account. ❌ .product({ ... }) from a personal account / missing businessOwnerId ✅ use a WhatsApp Business account and pass the required businessOwnerId WHY: product() requires businessOwnerId (non-optional) and a Business catalog; personal accounts can't.

Comparing mentions against @lid. ❌ if (msg.mentions.includes('123@lid')) — mentions are never @lid ✅ if (msg.mentions.some((j) => digitsOf(j) === OWNER)) — mentions are PN-resolved @s.whatsapp.net WHY: the decoder maps mention JIDs through lidMap to phone-number JIDs; comparing against a @lid JID never matches. Normalize to digits.

Poking the raw socket for profile/chat/contact/business ops → typed modules. ❌ client.socket.chatModify(...) / client.socket.updateProfileName(...) — untyped, version-fragile ✅ client.chat.archive(jid), client.profile.setName(name), client.contact.exists(num), client.business.catalog() — typed wrappers WHY: v4.4 exposes typed modules client.profile / chat / contact / business (plus client.pin/unpin, client.setDisappearing); prefer them over reaching into the raw Baileys socket.

Correctness — MEDIUM (HIGH if it crashes)

Two content methods on one builder. ❌ client.send(jid).text('hi').image('./a.jpg') — type error / intent lost ✅ client.send(jid).image('./a.jpg', { caption: 'hi' }) — one content method (use its own option to combine), or two separate send() calls, or .album([...]) for one bubble. WHY: each content method transitions 'init' → 'content-set' and is typed this: MessageBuilder<'init'> — only ONE is callable per builder.

Not awaiting the key before edit/react/delete/forward. ❌ const b = client.send(jid).text('hi'); await client.edit(b).text('bye') — b is a builder ✅ const key = await client.send(jid).text('hi'); await client.edit(key).text('edited') WHY: the builder is a thenable; await runs send() and resolves to the WAMessageKey. edit/react/delete/forward all take a WAMessageKey. Inside handlers prefer msg.reply() / msg.react().

Raw-JID owner/sender check → normalized digits. ❌ if (msg.senderId === '[email protected]') — device suffix :12 / @lid breaks it ✅ const digitsOf = (jid) => (jid.split(/[:@]/)[0] ?? '').replace(/\D/g, ''); if (digitsOf(msg.senderId) !== OWNER) return WHY: a JID may carry a device part or be a @lid; raw === fails. Normalize to bare digits.

Wrong JID format. ❌ client.send('628123456789') as a JID / .mentions(['628123456789']) ✅ client.send('[email protected]'), group [email protected], .mentions(['[email protected]']) WHY: user JID = <digits>@s.whatsapp.net, group JID = <id>@g.us. send() tolerates a raw string only via username resolution; mentions() throws INVALID_OPTIONS if an entry lacks @.

replied() used as a property → it's an async method. ❌ const q = msg.replied; if (q.text) — replied is a function, not a value ✅ const q = await msg.replied(); if (q) console.log(q.text) — returns MessageContext | null WHY: replied() is async and may be null; always await and null-check.

Using client.send(msg.senderId) instead of msg.reply() in a handler. ❌ await client.send(msg.senderId).text('hi') — loses the quote; in groups goes to the sender's DM ✅ await msg.reply('hi') — quotes the source and targets the correct room WHY: ctx.reply targets remoteJid ?? roomId ?? senderId; in a group that's the group, not a DM.

Missing qr handler. ❌ new Client() with only message handlers — headless = stuck, no way to scan ✅ client.on('qr', ({ qrString, expiresAt }) => console.log('Scan:', qrString)) WHY: with authType: 'qr' (default) you must surface the QR (or pairing-code for pairing). The qr event's expiresAt is epoch milliseconds (~60s).

limitedTimeOffer.expiresAt in ms instead of SECONDS. ❌ limitedTimeOffer: { text: 'Sale', expiresAt: Date.now() + 3600_000 } ✅ limitedTimeOffer: { text: 'Sale', expiresAt: Math.floor(Date.now() / 1000) + 3600 } WHY: this expiresAt maps straight to WhatsApp's expiration_time (Unix seconds), no conversion — passing ms yields a wildly future expiry. (Note the inconsistency: qr/ pairing-code expiresAt and message timestamp are ms; only this field is seconds.)

audio() voice-note surprise (ptt defaults true). ❌ await client.send(jid).audio('./song.mp3') — sent as a push-to-talk voice note + waveform ✅ await client.send(jid).audio('./song.mp3', { ptt: false }) — shareable audio file WHY: AudioOptions.ptt defaults true; pass ptt: false for a real file, leave default only when a voice note is intended.

Deps requiring Node 22 while zaileys targets Node 20+. ❌ adding a dep with engines: { node: ">=22" } (e.g. file-type v22) ✅ keep deps Node-20 compatible (zaileys pins file-type@^21 for this reason) WHY: package.json declares engines.node >=20.0.0 and tests Node 20/22/24; raising the floor breaks supported users.

☁️ Cloud provider (provider: 'cloud') — HIGH

Only audit these when the code sets provider: 'cloud'. Reference: cloud.md.

Cold / out-of-window send must be a template. ❌ await wa.send(newLead).text('Hi!') → Graph 131047. ✅ await wa.sendTemplate(newLead, 'welcome', 'en_US', components). WHY: the Cloud API only allows free-form messages inside the 24-hour window; cold outreach must be an approved template.

Webhook must verify signatures on a raw body. ❌ app.use(express.json()); app.post('/webhook', wa.webhook()) — parsed body breaks X-Hub-Signature-256 (401). ✅ express.raw({ type: '*/*' }) before the handler; set cloud.appSecret; subscribe the messages field. WHY: inbound is push + HMAC-verified; a body-parser corrupts the signature.

Inbound handlers must be idempotent. ❌ Charging/creating on every webhook POST. ✅ Dedupe by message id — Meta retries when you don't ack in ~10s (zaileys acks immediately).

No web-only surfaces on cloud. ❌ wa.group.*, wa.newsletter.*, wa.send().poll(), rich: true, wa.edit/delete/pin on cloud → UNSUPPORTED_ON_CLOUD. ✅ Use the unofficial provider, or wa.cloud.* for account/business ops.

Template params match {{n}}; secrets from env. ❌ Wrong param count (132000); hardcoded accessToken/appSecret. ✅ wa.cloud.templates.get() to verify; all cloud.* from process.env, permanent System User token (not the 24h quick-start token).

Quick verification cues

  • Providers: provider: 'baileys' (default) or 'cloud'. Cloud-only: wa.webhook(), wa.sendTemplate(), wa.markRead(id, {typing}), wa.cloud.* (templates/profile/info/phoneNumbers/flows/commerce/blocklist/qr/analytics/phone). Cloud events: message-status, template-status, flow-response, order. Web-only on cloud throws ZaileysProviderError('UNSUPPORTED_ON_CLOUD').
  • Error classes (all from zaileys): ZaileysBuilderError, ZaileysCommandError, ZaileysDomainError, ZaileysAutomationError, ZaileysStoreError, ZaileysCloudError, ZaileysProviderError.
  • Builder content methods: text, image, video, videoNote, audio, document, sticker, location, contact, poll, album, buttons, template, list, carousel, event, groupInvite, product, requestPhoneNumber, sharePhoneNumber, limitSharing. Modifiers: reply, mentions, mentionAll, disappearing, to.
  • Inbound events: message (umbrella — all types), text, image, video, audio, document, sticker, reaction, edit, delete, poll-vote, button-click, list-select, mention, mention-all, group-update, group-join, group-leave, member-tag, call-incoming, call-ended, history-sync, presence, newsletter. Connection: connect, disconnect, qr, pairing-code, reconnecting, auth-exhausted, error.
  • Client methods: connect, disconnect, logout, send, edit, delete, react, forward, broadcast, scheduleAt, pin, unpin, setDisappearing, rejectCall, command, use, on, off. autoConnect defaults true.
  • Typed modules: client.profile (setName/setStatus/setPicture/removePicture/getPicture/ getStatus), client.chat (archive/unarchive/pin/unpin/mute/unmute/markRead/markUnread/star/ unstar/delete/clear), client.contact (check/exists/save/remove), client.business (profile/catalog/collections/orderDetails/createProduct/updateProduct/deleteProduct).
  • If the code references anything NOT in these lists, treat it as suspect and verify against references/api.md before approving.
