读im_be的server/im_group_events.go确认:群聊创建/加人/踢人/解散/转让群主等全部事件都走 publishIMGroupRealtimeEvent,这个函数只会广播给"当前已订阅该群topic的会话"——对比P2P场景专门 有一条deliverIMConversationSystemMessageToP2PSessions,会无视订阅状态强制投递给双方的session, 群聊从未做过同等实现。实机验证:一个全新创建、成员从未打开过的群,即使对方账号完全在线、页面就 停留在/messages上,群条目和未读角标都不会出现,等多久都不会自愈,必须手动刷新页面。 由于这个topic客户端本来就不知道存在,没有任何东西可以"响应",前端无法真正修复,只能缓解:复用 subscribeMeTopic()/onReauthenticated()已经在用的withLaterSub()增量语义,改用getMeta()(不像 subscribe()那样在_attached为true时直接短路)定时(30秒)+ 切回标签页时主动拉一次"me"话题的最新 订阅列表。 实机验证:创建一个全新群、只邀请一个从未见过这个群的被动成员,在其页面保持被动、不做任何操作/ 刷新的情况下——模拟切换标签页触发的focus/visibilitychange事件后约十几秒内,群条目正确出现在 列表顶部;另一次未受干预的测试中,纯靠30秒定时器本身也确认能自愈。 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
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/.
For demo access and other instructions see here.
