Load message context

OpenIM React Native SDK guide for load message context.

Use fetchSurroundingMessages() to load messages before and after a known message, such as when opening a result from search or a reply.

const { messageList } = await OpenIMSDK.fetchSurroundingMessages({
  startMessage: targetMessage,
  viewType: ViewType.Search,
  before: 20,
  after: 20,
});

Parameters

Parameter	Type	Required	Description
`startMessage`	`MessageItem`	Yes	Retrieved anchor message.
`viewType`	`ViewType`	Yes	Context view type; use `ViewType.Search` for a search result.
`before`	`number`	Yes	Maximum messages to load before the anchor.
`after`	`number`	Yes	Maximum messages to load after the anchor.

The call returns { messageList }, where messageList contains the retrieved surrounding MessageItem[]. The number of messages may be less than before + after near a boundary or when messages have been deleted.
