连接 gun db 中的对等体

Question

我需要了解如何在 gun db 中连接对等点。我在 heroku 上部署了一个 socket.io 服务器，但我不知道它是否适用于 gun。任何有 gun db 经验的人都可以帮助我吗？我已经阅读了文档，但不清楚对等点是如何连接的，文档中也没有明确的代码示例。

我已经测试了聊天示例，但它不能在我的本地主机服务器上运行，我将无法将它部署到我的共享主机上，因为套接字是不允许的。同样在本地主机上，消息不会在两个不同的浏览器之间传递 windows。

这是添加了建议 lib/webrtc 的代码。还是不行。

哇@mauro-stepanoski 的评论太好了（应该是答案）！ @jihuuNI 当像 Todo-Dapp 教程中那样添加 lib/webrtc 适配器时，它会尝试自动将所有浏览器与所有其他浏览器连接 - 将来，AX 将自动切断不必要的连接。请注意，浏览器的 WebRTC 功能不是很可靠，因此您仍然希望拥有超级对等连接。
