I am a newbee for this library,And I got a question for Stream

I learned from the go-libp2p-examples Here Are my Questions

I found it will openstream every time ,should i do this in my project?
if server A is shutdown , but client B can still send msg through stream ,Should I openNewStream and try again if i havent heard any response (same as the last one)
can i hold stream for a really long time

Hi, Thanks for the answer ; But it seems not enough to solve my question , I was wandering if I have to write another protocol to detected whether peer is dead or not (but I think libp2p already did this ? right ? pingProtocol?) Thanks anyway

I have created a chat app using Gioui and Libp2p. The app is also published at Playstore, Protonet. Going to make it open source in a day or two. Then hopefully you and others will be able to see it's source code. Thanks :)
