// Setting up a data connection in JS using WebRTC is relatively straightforward. First, you need to create a RTCPeerConnection object. This object will be used to establish the connection between two peers.
|
|
|
|
// Create an RTCPeerConnection object
|
|
let pc = new RTCPeerConnection();
|
|
|
|
// Create a data channel
|
|
let dataChannel = pc.createDataChannel('dataChannel');
|
|
|
|
// Set up the ICE candidate handler
|
|
pc.onicecandidate = (e) => {
|
|
if (e.candidate) {
|
|
// Send the candidate to the remote peer
|
|
sendIceCandidate(e.candidate);
|
|
}
|
|
};
|
|
|
|
// Set up the data channel handler
|
|
dataChannel.onopen = () => {
|
|
// The data channel is now open
|
|
// You can now send data
|
|
};
|
|
|
|
// Create an offer
|
|
pc.createOffer().then((offer) => {
|
|
// Set the local description
|
|
pc.setLocalDescription(offer);
|
|
// Send the offer to the remote peer
|
|
sendOffer(offer);
|
|
});
|
|
|
|
// When the remote peer sends an answer
|
|
pc.setRemoteDescription(answer);
|
|
|
|
// When the remote peer sends an ICE candidate
|
|
pc.addIceCandidate(candidate);
|
|
|
|
// Now the connection is established and you can send data using the dataChannel object
