Load message history in reverse

Retrieve history from a message anchor toward newer messages.

Use the reverse history API when you already have a message anchor and need to fill in messages that come after it.

Parameters

Parameter	Type	Required	Description
`conversationID`	`string`	Yes	ID of the conversation whose messages to retrieve.
`startClientMsgID`	`string`	Yes	Anchor message ID from which to read toward newer messages.
`count`	`number`	Yes	Maximum number of messages to retrieve.
`viewType`	`ViewType`	Yes	Message viewing direction. Use `ViewType.History` when loading history.

import { ViewType } from '@openim/wasm-client-sdk';

const { data: page } =
  await openimsdk.getAdvancedHistoryMessageListReverse({
    conversationID,
    startClientMsgID: anchorMessage.clientMsgID,
    count: 30,
    viewType: ViewType.History,
  });

When the Promise resolves, data is an AdvancedGetMessageResult. For field descriptions and result-status handling, see Load message history. On this page, isEnd indicates whether the query has reached the boundary in the newer-message direction.

Do not mix both loading directions at the same scroll boundary. Deduplicate merged results by conversationID:clientMsgID.
