Class: WebChatChannelAdapter

Defined in: packages/agentos/src/io/channels/adapters/WebChatChannelAdapter.ts:147

Channel adapter for web-based chat using HTTP/WebSocket.

Methods

attachToServer()

attachToServer(server): void

Defined in: packages/agentos/src/io/channels/adapters/WebChatChannelAdapter.ts:195

Attach to an existing HTTP server instead of creating a standalone one. Must be called before initialize.

Node.js http.Server instance (e.g., from Express).

Returns

void

---

doConnect()

protected doConnect(auth): Promise<void>

Defined in: packages/agentos/src/io/channels/adapters/WebChatChannelAdapter.ts:201

Establish the platform connection using the supplied credentials. Called by initialize after state has been set to connecting. Must throw on failure — the base class handles retry and state changes.

Parameters

auth

ChannelAuthConfig & object

Returns

Promise<void>

Overrides

BaseChannelAdapter.doConnect

---

doSendMessage()

protected doSendMessage(conversationId, content): Promise<ChannelSendResult>

Defined in: packages/agentos/src/io/channels/adapters/WebChatChannelAdapter.ts:281

Deliver a message to the external platform. Called by sendMessage only when the adapter is connected.

Parameters

conversationId

string

content

MessageContent

Returns

Promise<ChannelSendResult>

Overrides

BaseChannelAdapter.doSendMessage

---

doShutdown()

protected doShutdown(): Promise<void>

Defined in: packages/agentos/src/io/channels/adapters/WebChatChannelAdapter.ts:322

Release platform resources (close WebSocket, stop polling, etc.). Called by shutdown before the state transitions to disconnected.

Returns

Promise<void>

Overrides

BaseChannelAdapter.doShutdown

---

emit()

protected emit(event): void

Defined in: packages/agentos/src/io/channels/adapters/BaseChannelAdapter.ts:265
