This Node.js project is bootstrapped with yarn2. This is a simple implementation of a Video Chat App built with Socker.io and Peerjs

First Install peerjs globally :

npm i -g peer

then, run the express server :

npm run start:dev

# or

yarn start:dev

finally run the peerjs server :

peerjs --port 3004 # change the default port  as you want

• Open http://localhost:3003.
• Authorize your browser to access to your camera
• Copy the url with the generated roomId and open it in a new tab (you should now see 2 users connected to the room with their video stream)

If you want to make a quick demo with different users on different networks (Other computer, smartphones etc.). You can try NgRok

First install it :

# Macos
brew install ngrok/ngrok/ngrok
# Windows
choco install ngrok
# Linux 
sudo tar xvzf ~/Downloads/ngrok-v3-stable-linux-amd64.tgz -C /usr/local/bin

Connect to the NgRok Dashboard and follow the installation process

Update your local ngRok config file (~/.ngrok2/ngrok.yml) like this :

authtoken: <YourAuthToken>
tunnels:
  peer: # give the name you want
    addr: 3004
    proto: http
  node: # give the name you want
    addr: 3003
    proto: http

Run ngrok tunnel :

ngrok start --all

Copy ngRok's generated urls (free plan) :

Forwarding    https://d18b-93-1-15-153.ngrok.io -> http://localhost:3004
Forwarding    https://faaf-93-1-15-153.ngrok.io -> http://localhost:3003

Go to public/script.js and replace myPeer host and port by the ngRok's url pinned on port 3004 :

const  myPeer = new  Peer(undefined, {
	host:  'd18b-93-1-15-153.ngrok.io',
	port:  '443' // default port for https
});

Now you can visit the ngRok's url pinned on port 3003 (https://faaf-93-1-15-153.ngrok.io in the example) and share the link with the roomId to a friend.
