Implements automatic version updates that are transparent to users:
- Checks for new WhatsApp Web version every 6 hours (configurable)
- When new version detected, saves it for next natural reconnection
- Emits 'version.update' event so users can track updates
- No disconnection required - WhatsApp naturally reconnects every 30min-2h
- Cleans up interval when socket closes
Configuration:
```typescript
const sock = await makeWASocketAutoVersion({
auth: state,
versionCheckIntervalMs: 6 * 60 * 60 * 1000 // 6 hours (default)
})
sock.ev.on('version.update', ({ currentVersion, newVersion, isCritical }) => {
console.log(`New version: ${newVersion.join('.')}`)
})
```
Adds a new async function that automatically fetches the latest
WhatsApp Web version from web.whatsapp.com before connecting.
Usage:
```typescript
// Option 1: Auto-fetch version (recommended)
const sock = await makeWASocketAutoVersion({ auth: state })
// Option 2: Manual version (existing behavior)
const sock = makeWASocket({ auth: state })
```
Benefits:
- No need to update library for version changes
- Automatic fallback to bundled version if fetch fails
- Logged warnings when using fallback
Changes:
- Update frequency: weekly → daily (06:00 UTC)
- Add retry with exponential backoff (3 attempts per source)
- Add multiple source endpoints (sw.js + bootstrap page)
- Add version validation (sanity checks on revision numbers)
- Add fetch timeout to prevent hanging
- Add detailed logging for debugging
- Simplify workflow to only update baileys-version.json
This makes the version update more reliable and responsive
to WhatsApp Web changes.
Instead of maintaining the version number in 3 separate files
(baileys-version.json, index.ts, generics.ts), this change makes
baileys-version.json the single source of truth. Other files now
import the version from this JSON file.
This follows the DRY principle and reduces:
- Risk of version inconsistency across files
- Maintenance burden (only 1 file to update)
- PR diff size (3 files → 1 file for version updates)
- Merge conflict probability
Addresses inefficiency found in Baileys PR #2269.
Messages from Facebook/Instagram ads (Click-to-WhatsApp) don't arrive on
linked devices because Meta's ads endpoint doesn't encrypt for multi-device.
They arrive as "Message absent from node" placeholders.
This change automatically requests the message from the primary phone via
PDO (Peer Data Operation) when a CTWA placeholder is detected.
Changes:
- Add enableCTWARecovery config option (default: true)
- Trigger requestPlaceholderResend() for "Message absent from node" errors
- Add Prometheus metrics for CTWA recovery tracking
- Add comprehensive unit tests for CTWA recovery functionality

Motivation
Avoid duplicate contacts when the same user arrives sometimes as a PN and sometimes as a LID.
Ensure that LID↔PN mappings acquired via history and event synchronization are used immediately.
Improved performance and scalability with batch searches (inspired by PR #2274).
Description
Incoming JID normalization: added normalizeMessageJids to convert remoteJid/participant LID → PN when available, keeping LID as fallback if PN does not already exist.
Batch lookups: getLIDsForPNs and getPNsForLIDs now use batch DB, bidirectional caching, and fallback to USync, reducing individual calls.
Automatic hydration: lidPnMappings from history sync are persisted in the store so that future LID messages are resolved immediately.
Fallback logs: logs detail when LID→PN resolves and when new mappings are stored (history sync and lid-mapping.update).
Tests
Added tests for batch PN→LID, batch LID→PN, and LID→PN normalization fallback.
✅ Changes applied
Summary
Added batch tests for PN→LID and LID→PN resolution
Added tests for normalizeMessageJids cobrindo sucesso e fallback (LID permanece quando PN não existe).

Changes to src/Utils/history.ts:
- Add isPersonJid() helper to validate JID types for mapping eligibility
- Add extractLidPnFromConversation() for conversation-level mapping extraction
- Add extractLidPnFromMessage() for message-level mapping extraction
- Modify processHistoryMessage() to extract from 3 sources with deduplication
- Fix validation bug: use || (OR) instead of && (AND) to prevent poisoned mappings
Changes to src/__tests__/Utils/history.test.ts:
- 55 comprehensive tests covering all new functions and edge cases
- Tests for all JID formats (@lid, @hosted.lid, @s.whatsapp.net, @hosted)
- Tests for skipped JIDs (@g.us, @broadcast, @newsletter)
- Tests for bug fix validation (person + group, person + broadcast, etc.)
- Tests for deduplication across all three sources
Related issues:
- ClosesWhiskeySockets/Baileys#2282
- Partially addresses WhiskeySockets/Baileys#2281
Merge master branch and resolve conflicts:
- Use import from '../WABinary/index.js' (master convention)
- Keep the bug fix: || instead of && in extractLidPnFromMessage
- Combine comprehensive tests from both branches
- Use Map for deduplication (master implementation)
All 55 tests passing.
Address PR #20 code review feedback:
- Fix logical bug: changed `&&` to `||` in isPersonJid validation
This ensures BOTH JIDs must be person JIDs before extracting
a LID-PN mapping, preventing "poisoned" mappings where one side
is a group/newsletter/broadcast
- Add isPersonJid() helper to validate JID types
- Add extractLidPnFromConversation() to extract mappings from
conversation lidJid/pnJid properties
- Add extractLidPnFromMessage() to extract mappings from message
remoteJidAlt/participantAlt fields
- Update processHistoryMessage() to use new extraction functions
- Add comprehensive tests covering edge cases for mixed JID types
(person + group, person + broadcast, person + newsletter)
Note: Returning `undefined` is the correct TypeScript convention
for indicating absence of value (as per TypeScript team guidelines)
Enhances LID-PN mapping extraction to handle all WhatsApp JID formats
and extract mappings from multiple sources within history sync data.
New JID validation:
- Add `isPersonJid()` helper to identify JIDs that can have LID-PN mappings
- Skip non-person JIDs: @newsletter (channels), @broadcast, @g.us (groups)
Triple-source extraction:
1. Top-level `phoneNumberToLidMappings` array (existing)
2. Conversation objects via `lidJid`/`pnJid` properties (existing)
3. Message objects via `remoteJidAlt`/`participantAlt` fields (NEW)
New `extractLidPnFromMessage()` function:
- Extracts mappings from message key alternative JID fields
- Handles both direct messages (remoteJidAlt) and group messages (participantAlt)
- Properly identifies LID vs PN based on server type
JID formats handled:
- @s.whatsapp.net - Standard phone number
- @lid - Logical ID (privacy)
- @hosted - Hosted phone number
- @hosted.lid - Hosted LID
46 comprehensive tests covering all scenarios.
Related: WhiskeySockets/Baileys#2263
WhatsApp provides LID-PN mappings in two locations within history sync:
1. Top-level `phoneNumberToLidMappings` array (already processed)
2. Individual conversation objects with `lidJid`/`pnJid` properties (new)
This change adds extraction from conversation objects, ensuring maximum
mapping coverage regardless of sync type or payload structure.
Key improvements:
- Add `extractLidPnFromConversation()` function with comprehensive JSDoc
- Use Map for O(1) deduplication of mappings across both sources
- Handle all JID formats: @lid, @hosted.lid, @s.whatsapp.net, @hosted
- Normalize JIDs using `jidNormalizedUser()` for consistency
- Skip group chats (@g.us) that don't have LID-PN mappings
Includes 22 comprehensive tests covering:
- LID chat with pnJid extraction
- PN chat with lidJid extraction
- Hosted format handling
- Deduplication between sources
- Edge cases (nulls, groups, missing data)
- All conversation sync types

Wrap URL parsing in try/catch to prevent server crashes from malformed
requests (invalid percent-encoding, problematic Host headers, etc.).
Returns 400 Bad Request instead of crashing the process.
Prometheus Metrics:
- Add METRICS_LABELS fallback for defaultLabels env config
- Separate includeSystem from collectDefaultMetrics with own env var
- Parse URL in /metrics endpoint to support querystrings and trailing slashes
- Sort keys in labelsToKey for stable/deterministic lookups
- Update documentation with all environment variables
Retry Utils:
- Remove abort listener on sleep completion to prevent memory leak
- Apply maxDelay cap AFTER jitter to guarantee max delay limit
- Validate/normalize attempt parameter in calculateDelay
- Count retries only when attempt > 1 (actual retry, not first try)
- Use metrics.retryExhausted instead of generic errors for exhausted retries
Tests:
- Add consistency tests to verify retryConfigs.rsocket matches constants
- Re-export RETRY_BACKOFF_DELAYS and RETRY_JITTER_FACTOR from Defaults
for backwards compatibility with existing imports
- Add 'as const' to RETRY_JITTER_FACTOR for type consistency
- Improve documentation explaining why values are hardcoded in retryConfigs
(ESM initialization order issues with indirect circular imports)
Hardcode values in retryConfigs.rsocket instead of referencing
RETRY_BACKOFF_DELAYS and RETRY_JITTER_FACTOR to avoid
"Cannot access before initialization" error in ESM module loading.
- Remove duplicate RETRY_BACKOFF_DELAYS and RETRY_JITTER_FACTOR from Defaults/index.ts
- Export constants from retry-utils.ts as single source of truth
- Add 'as const' for better type inference
- Fixes "Cannot access 'RETRY_BACKOFF_DELAYS' before initialization" error
- Add registryConfigured flag to ensure single execution of configureRegistry
- Fix race condition by moving setMetricPrefix/configureRegistry before Promise
- Remove unused prefix parameter from configureRegistry function
- Consolidate prefix to single source of truth (configuredPrefix global)
- Allow clearing default labels by passing empty object
- Add resetMetricsConfiguration() and getConfiguredPrefix() for testing
- Apply configured prefix to all metric names via getFullMetricName()
- Configure customRegistry with defaultLabels at initialization
- Prevent memory leak: collectDefaultMetrics only called once via flag
- collectDefaultMetrics now uses customRegistry instead of global
- Initialize prefix/defaultLabels before creating baileysMetrics
All metrics now properly include prefix (e.g., baileys_connection_attempts)
and inherit defaultLabels configured via environment variables.
Major improvements to prometheus-metrics.ts:
- Use custom registry instead of global promClient.register (isolation)
- Remove duplicate localValues - prom-client is now single source of truth
- Fix reset(labels) to respect labels param using remove() instead of reset()
- Migrate Summary class to use prom-client internally
- getMetricsOutput() now uses customRegistry for proper isolation
Fix misleading comments in retry-utils.ts:
- Change "exponential backoff" to "custom progressive backoff"
- Fix comment claiming constants are "from Defaults" (now local)
Breaking changes to getValues()/get() - now async as they query prom-client
Define RETRY_BACKOFF_DELAYS and RETRY_JITTER_FACTOR locally in
retry-utils.ts to avoid circular dependency that caused
"Cannot access 'RETRY_BACKOFF_DELAYS' before initialization" error.
- Add prom-client ^15.1.3 as production dependency
- Migrate Counter class to use prom-client internally
- Migrate Gauge class to use prom-client internally
- Migrate Histogram class to use prom-client internally
- Update getMetricsOutput() to use prom-client's native metrics()
- Update contentType() to use prom-client's contentType
- Enable collectDefaultMetrics() for Node.js system metrics
- Maintain backward compatibility with existing API
Benefits:
- Native OpenMetrics format export
- Proper histogram bucket handling
- Default Node.js metrics (memory, CPU, event loop, GC)
- Better integration with Grafana/Prometheus ecosystem
- Integrate RETRY_BACKOFF_DELAYS and RETRY_JITTER_FACTOR into retry-utils.ts
- Add retryConfigs.rsocket using the default delays
- Add getRetryDelayWithJitter() helper function
- Add getAllRetryDelaysWithJitter() for planning
- Document DEFAULT_CACHE_MAX_KEYS with usage example
- Adjust INITIAL_PREKEY_COUNT from 30 to 200 (moderate value)
- Adjust MIN_UPLOAD_INTERVAL from 60s to 10s (balance rate limiting/responsiveness)
- Revert syncFullHistory to true (avoid breaking change)
Based on RSocket's battle-tested configuration:
- Add maxWebSocketListeners config option (default: 20)
- 8 base WS events + 10 dynamic listeners + 2 buffer slots
- Add maxSocketClientListeners config option (default: 50)
- Replace dangerous setMaxListeners(0) with configurable limits
- Add warning log if user explicitly sets limit to 0
BREAKING: Previous behavior used setMaxListeners(0) which removed
all limits. Now defaults to safe limits but can be overridden via config.
- Add DEFAULT_CACHE_MAX_KEYS with limits per store type (prevents memory leaks)
- Add RETRY_BACKOFF_DELAYS [1s, 2s, 5s, 10s, 20s] for exponential backoff
- Add RETRY_JITTER_FACTOR (0.15) to prevent thundering herd
- Change INITIAL_PREKEY_COUNT from 812 to 30 (safer for rate limiting)
- Change MIN_UPLOAD_INTERVAL from 5s to 60s (avoids rate limiting)
- Change syncFullHistory default to false (conservative approach)
Based on RSocket fork's production-tested configuration.
