Golang Chat

Goal

This is a dead simple "chat" system. This system is built in two parts:

• Server Receiving messages from a network interface (any kind) and forwarding them to all the connected clients
• Client A process reading a string on STDIN and forwarding it to the server, and also receiving messages from the same server and writing them to STDOUT.

How to run this code

The code is written in Golang, and uses modules.

Therefore, you must have Golang version > 1.11 installed on your system to be able to build and execute this code.

• To launch the Server, issue the following command inside the server/cmd folder:

go run main.go

If the command is successful, you should be able to see the following output in your console:

2021/01/24 15:58:59 Chat Server listening on port 6697

• To run a new Client, issue the following command inside the client/cmd folder:

go run main.go

Each new client will have a username automatically generated, so if the command is successful, you will see this kind of output in your console:

021/01/24 16:01:45 Client connected to server / port 6697

Then you can enter the text you want after the prompt (>) and see how the Server and the other Clients react. You can even kill (CTRL+C) the Server or one of the Client and see what happens!
