PeerChat - Terminal-Based WebRTC Chat

PeerChat is a lightweight, terminal-based peer-to-peer chat application built using WebRTC and Pion. It allows two users to chat directly without a central server.

🚀 Features

✅ Peer-to-peer communication using WebRTC
✅ Secure, serverless chat
✅ Simple CLI commands to create and join rooms
✅ Works over the terminal

---

📦 Installation

Clone the repository and build the binary:

git clone https://github.com/aminGhafoory/peerchat.git
cd peerchat
go build -o peerchat main.go

---

🔗 Usage

1️⃣ Create a New Chat Room

Run the following command to start a new WebRTC session and generate an Offer SDP:

peerchat new

🔹 Copy the SDP Offer and send it to the person who wants to join.

---

2️⃣ Join an Existing Chat Room

If someone has already started a chat session, use this command and paste their SDP Offer:

peerchat join

🔹 After joining, you will get an Answer SDP. Share this back with the initiator to establish the connection.

---

📌 Notes

• PeerChat requires both users to manually exchange SDP offers/answers.
• This implementation does not include a signaling server. You must share SDPs manually (e.g., via another chat app).
• Future versions might include automatic signaling using WebSockets or QR codes.
