* fix(whatsapp): add error handling for inbound message processing
Wrap handleInboundMessage calls in try/catch to log errors if
synchronous processing fails (e.g., thread ID encoding). The async
processing already has its own error handling in Chat.processMessage.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): prevent markdown regex from matching across newlines
Use [^\n*] and [^\n~] in fromWhatsAppFormat regex to prevent bold/strike
spans from merging across line boundaries. Adds a regression test.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): use WhatsAppInteractiveMessage type instead of object
Replace the untyped `object` parameter in sendInteractiveMessage with
the proper WhatsAppInteractiveMessage type for full type safety.

* fix(whatsapp): hoist emoji mapping to module-level constant
Move the emoji name-to-unicode mapping out of resolveEmoji() so it is
not re-allocated on every call.

* fix(whatsapp): remove duplicate JSDoc comment in types
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(example): add startTyping to WhatsApp recording methods
The adapter supports typing indicators but the method was missing from
the recording proxy list.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): fix formatting and add package to readme test allowlist
Fix line-length formatting in markdown.ts regex and add
@chat-adapter/whatsapp to the valid packages list in readme tests.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): use defaultEmojiResolver instead of custom emoji map
Replace the hand-rolled EMOJI_MAP with the shared defaultEmojiResolver
from the chat SDK. WhatsApp uses unicode emoji like GChat, so toGChat()
provides the correct mapping with broader coverage.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): make Graph API version configurable
Add apiVersion option to WhatsAppAdapterConfig (defaults to v21.0)
so users can upgrade without waiting for a package release.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): validate lat/lng before constructing Google Maps URL
Coerce and validate latitude/longitude with Number.isFinite() to
prevent unexpected URL construction from malformed webhook payloads.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): throw on editMessage instead of silently sending new message
Callers expecting an edit would get duplicate messages with the silent
fallback. Throwing makes the unsupported operation explicit.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): document regex asymmetry between toWhatsApp and fromWhatsApp
Explain why toWhatsAppFormat doesn't need newline guards like
fromWhatsAppFormat does — the standard markdown parser output
never produces spans crossing line boundaries.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): document callback data passthrough behavior
Add comments explaining that non-prefixed and malformed callback data
is intentionally passed through for legacy/external button IDs.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): add editMessage and deleteMessage to recording methods
Include all adapter methods in the recording list for complete
debugging traces, even for unsupported operations.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): preserve escaped formatting chars in toWhatsAppFormat
Escaped asterisks and tildes in standard markdown (e.g. \* and \~) are
now preserved through the conversion pipeline so WhatsApp renders them
as literal characters instead of misinterpreting them as formatting.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): split long messages instead of truncating
Replace silent truncation at 4096 chars with message splitting that
breaks on paragraph (\n\n) then line (\n) boundaries, sending multiple
messages so no content is lost. Adds 8 tests for the splitting logic.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix(whatsapp): align editMessage/deleteMessage behavior and docs
- Fix README: editMessage/deleteMessage both throw, not fallback/no-op
- Fix editMessage JSDoc to reflect it throws
- Make deleteMessage throw instead of silently warning (consistent with editMessage)
- Bump @types/node to ^25.3.2 to match monorepo
- Add sample-messages.md with webhook payload examples
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* docs(whatsapp): add adapter documentation page
Add whatsapp.mdx covering installation, usage, Meta app setup,
webhook config, interactive messages, media attachments, 24-hour
messaging window, configuration, features, and troubleshooting.
Also add WhatsApp to the adapters navigation in meta.json.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: add whatsapp adapter debug logging and try/catch
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(whatsapp): convert emoji placeholders in outgoing messages
WhatsApp adapter was sending raw {{emoji:wave}} placeholders instead of
Unicode emoji. Apply convertEmojiPlaceholders on all outgoing paths:
text messages, card fallback text, and interactive message fields.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix button rendering and streaming (needs to buffer)
* fix(example): handle editMessage failure on WhatsApp
WhatsApp Cloud API doesn't support message editing. Catch the error
in the demo "processing" animation and send a follow-up instead.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(chat): add onDirectMessage handler, stop treating DMs as mentions
DMs now route to dedicated onDirectMessage handlers instead of being
forced through onNewMention. If no DM handlers registered, DMs fall
through to onNewMention for backward compat. Adapters no longer set
isMention=true for DMs — the Chat SDK handles routing via adapter.isDM().
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(chat): always route DMs to onDirectMessage regardless of subscription
Previously, onDirectMessage only fired for unsubscribed DM threads.
Subscribed DMs were routed to onSubscribedMessage, which was confusing
on non-threaded platforms (WhatsApp, Telegram) where all DMs share one
threadId — after the first message, onDirectMessage never fired again.
Now, DMs always route to onDirectMessage first, and onSubscribedMessage
only handles non-DM subscribed threads. Backward compat is preserved:
if no onDirectMessage handlers are registered, DMs fall through as
mentions.
The example bot is simplified accordingly — onDirectMessage now fetches
conversation history via fetchMessages each time instead of relying on
subscribe() and stored state.

* feat(chat): pass channel as third argument to DirectMessageHandler
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(example): reply to channel instead of thread in DM handler
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(example): use thread instead of channel for DM operations
Channel ID is only two parts (whatsapp:{phoneNumberId}) which isn't a
valid conversation target on WhatsApp. The thread ID includes the user
phone and is required for startTyping/post/fetchMessages.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Revert "fix(example): use thread instead of channel for DM operations"
This reverts commit f4801d7015.
* fix(adapters): return valid thread IDs from channelIdFromThreadId
WhatsApp's channelIdFromThreadId was stripping the user WA ID, producing
an invalid ID that caused ValidationError on channel operations like
startTyping(). Since every WhatsApp conversation is a 1:1 DM, channel
and thread are identical.
Telegram's channelIdFromThreadId was returning a raw chatId without the
telegram: prefix, which is not a valid thread ID for adapter operations.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(chat): normalize fullStream in Channel.post() to extract text deltas
Channel.post() was coercing AI SDK fullStream objects to strings via +=,
producing "[object Object]" output. Now uses fromFullStream() to extract
text-delta events, matching how Thread.post() already handles streams.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(example): use thread.allMessages for DM history instead of adapter directly
The DM handler was calling channel.adapter.fetchMessages() which always
returns empty on WhatsApp (no native history API). Now uses
thread.allMessages which falls back to the persisted message history
cache, giving the AI conversation context.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* feat(chat): add message history support to Channel for DM platforms
Channel now falls back to the persisted message history cache when the
adapter lacks native message fetch (e.g. WhatsApp, Telegram). Incoming
messages are persisted under both thread and channel IDs. Outgoing
messages from channel.post() are also persisted.
The example DM handler now uses channel.messages instead of calling the
adapter directly.

* fix(whatsapp): improve markdown rendering and remove broken typing indicator
- Convert headings to bold text, thematic breaks to text separators,
and tables to code blocks (WhatsApp doesn't support these)
- Convert standard italic (*text*) to WhatsApp italic (_text_) since
WhatsApp uses *text* for bold
- Make startTyping a no-op (Cloud API doesn't support typing indicators)
- Update channelIdFromThreadId test for channel===thread change
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(example): reverse channel.messages to chronological order for AI
channel.messages yields newest first but AI expects chronological order.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(chat): auto-sort messages chronologically in toAiMessages
toAiMessages now sorts by dateSent (oldest first) so callers don't need
to worry about iteration order from channel.messages or thread.messages.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(chat): pass accumulated stream text as markdown in Channel.post()
Stream text was posted as a plain string, bypassing the adapter's format
converter. Now wraps it as { markdown: accumulated } so headings, bold,
italic etc. are properly converted for each platform.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(whatsapp): use stringifier options for emphasis and bullets
Use emphasis: '_' and bullet: '-' options in stringifyMarkdown so the
only * in output is **strong**, avoiding conflicts between list bullets
and italic markers. Simplifies toWhatsAppFormat to only convert
**bold** -> *bold* and ~~strike~~ -> ~strike~.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix(whatsapp): flatten bold inside headings to avoid triple asterisks
When AI outputs headings with bold text like `## **Choose React if:**`,
the heading-to-bold conversion created nested strong nodes producing
`***text***`. Now flattens strong children in headings so they merge
into a single bold span.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test(whatsapp): add full toBe assertion for complex markdown conversion
Also use ━━━ for thematic breaks instead of --- to avoid remark escaping.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* test: add WhatsApp replay tests from production recordings
Adds WhatsApp DM replay test infrastructure:
- Fixture from real webhook recordings (dm/whatsapp.json)
- WhatsApp test utilities with HMAC-signed request factory and
Graph API fetch mock (whatsapp-utils.ts)
- 6 replay tests covering DM handling, thread/channel IDs, message
sending, status update filtering, sequential messages, and
message history persistence

* Add missing @vitest/coverage-v8 dev dependency
The vitest config specifies coverage provider "v8" but the package
was missing from devDependencies.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* Drop drizzle-orm, use raw postgres queries
The adapter only needs 3 simple tables with basic CRUD. drizzle-orm is
a full ORM that adds significant dependency weight for no real benefit
here. The ensureSchema() method was already using raw queries. This
halves the dependency surface to just the postgres driver.

* Fix expiresAt parsing in acquireLock
The postgres library returns timestamptz columns as JavaScript Date
objects, not strings. Wrapping in new Date() was unnecessary overhead.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* Document lock atomicity difference vs Redis adapters
The Postgres ON CONFLICT approach relies on row-level locking rather
than a single atomic SET NX PX like Redis. Note this for users who
need high-contention distributed locking.

* Use crypto.randomUUID() for lock token generation
Math.random() is not cryptographically secure and has a higher
