Real-time messaging facility over a computer network🏃

💡Main idea💡

Create a software tool for exchanging text messages that works on a local network in peer-to-peer mode. Each messaging participant (node) is identified by an IP address and an arbitrary name that is specified by the user (via a command line parameter). Names are not required to be unique. Each node uses UDP to form a list of active nodes (IP addresses and names):

• once started, the node sends a broadcast packet containing its name to notify other nodes on the network of its connection to the network;
• other nodes that receive such a packet establish a TCP connection for messaging with the sender and send their name over it for identification in the chat.
  

A new client can join the chat at any time. Messages are exchanged using TCP in a logically shared space: each node maintains one TCP connection with every other node and sends its messages to all nodes in the network. Disabling a node must be correctly handled by other nodes.

🔎How to Install🔍

• Clone project to your folder: git clone https://github.com/amarjin6/chat-room.git
• Check for updates and install all necessary plugins
• Run project

🛠How to Use🛠

Run the project in your terminal with different IP's

python chat.py [host] [username]

Establish connection

Connection established automatically after each member joins chat

Example: New member joined chat

python chat.py 127.0.0.1 Alex
Alex joined chat

Warning
Don't use the same host for multiple members!

Sending messages

After connection to the server, you can easily communicate with all members in the chat

Example: Alex 'Hello, it's ME!'

hh:mm:ss Alex: Hello, it's ME!

There you can see the time, when each member sent the message
