TCP client with reconnecting and errors catch

[JuanPablo AJ]

Until now, I have found some examples related to creating a simple TCP client, like these:

http://www.inanzzz.com/index.php/post/j3n1/creating-a-concurrent-tcp-client-and-server-example-with-golang

https://www.linode.com/docs/guides/developing-udp-and-tcp-clients-and-servers-in-go/

Those articles were a great start.

Where may I found more complex examples? for example TCP clients with reconnection or clients prepared for different error cases.

Do you recommend some articles, books, or open-source projects related to learning related to that?

Thanks a lot for your help.
