-
Using npm: In your terminal, run:
npm install peer -
Via CDN: Include the following script in your HTML file:
“`html
“`
Creating a Simple Peer Connection
The fundamental usage of PeerJS involves creating a peer connection. Below is a lightweight example demonstrating how to set up a peer connection:
“`javascript
// Create a Peer
const peer = new Peer();
// Open a connection
peer.on(‘open’, function(id) {
console.log(‘My peer ID is: ‘ + id);
});
// Receiving an incoming call
peer.on(‘call’, function(call) {
call.answer(); // Answer the call with an A/V stream
call.on(‘stream’, function(remoteStream) {
// Show stream in some video/canvas element
});
});
“`
This code lays the foundation for setting up a connection using PeerJS effortlessly.
