useXConversations

管理会话列表和当前会话。conversations 与 activeConversationKey 是 shallowRef，和 useXChat 的 conversationKey 对上之后，每个会话有自己的消息。

const {
  conversations,
  activeConversationKey,
  setActiveConversationKey,
  addConversation,
  removeConversation,
  setConversation,
  setConversations,
  getConversation,
  getMessages,
} = useXConversations({
  defaultConversations: [{ key: '1', label: 'New chat' }],
  defaultActiveConversationKey: '1',
});

addConversation(conversation, 'prepend' | 'append')。会话对象至少要有 key。

基础使用

• Conversation Item 1
• Conversation Item 2
• This's Conversation Item 3, you can click me!
• Conversation Item 4

基础使用

用 useXConversations 驱动会话列表。
