message-center-view.jsx 的预览文字读 topic.latestMessage()，这个方法
只会从话题自己的本地消息缓存里取值——而这个缓存只有在话题真正被
subscribe 过一次数据拉取后才会填充。me.contacts()（resetContactList）
给出的是每个联系人真实的、已缓存的Topic实例，包括用户这次会话里
从未打开过的——这些话题的latestMessage()恒为undefined，即使同一个
对象自己的touched/seq字段能证明服务端真实存在历史消息。
新增prefetchLatestMessagePreviews()：对chatList里seq>0但本地缓存为空
的话题，一次性拉取最新1条消息填充预览。用一个Set跟踪已尝试过的话题，
避免resetContactList()（几乎每个{meta}/{pres}事件都会触发一次）反复
重新拉取同一个话题。
调试过程中发现并修正了自己犯的两个错误：(1) resetContactList()在
websocket握手完成前就会被本地持久化缓存恢复触发一次，此时的subscribe
必然503失败，加了isConnected()判断跳过，避免过早失败把话题永久标记
为"已尝试"；(2) Topic.subscribe(getParams, setParams)的参数顺序搞反，
把查询对象传成了第二个参数(setParams)，导致subscribe成功但发出的
{sub}包完全没有get子句，从未真正请求过消息数据。
已用真实浏览器验证：好友kcg051307会话（真实71条历史消息）刷新页面
后预览从"暂无消息"变为真实的最新消息内容，未读角标数字不受影响
（确认没有误将未读消息标记为已读）。

Tinode Web
Briefing
Single-page web chat application for Tinode. The app is built on React. The Tinode javascript SDK has no external dependencies. Overall, it's a lot like open source WhatsApp or Telegram web apps.
Although the app is generally usable, keep in mind that this is work in progress. Some bugs probably exist, some features are missing. The app was tested in the latest Chrome & Firefox only. NPM package is available.
Try possibly newer or older version live at https://sandbox.tinode.co/.
