Realtime chat socket.io
Hello everyone, this is a question, I am doing a chat on react socket-client, nodejs express mongoose typescript socket.io, how do I want to add logic to send, receive, read or receive an error message on error ie isSent, isDelivered, isRead, isError. in general, I understand the logic, but I don't know how to implement it so that it works correctly, especially when one of the participants is not online (the chat is for 2 people so far). Maybe someone did something similar
