Persistence of sessions

[willwade]

on the display side we need to have a way of having a session more persistent eg

const sessionId = generateSessionToken(); /
localStorage.setItem("owdSessionId", sessionId);

then on load

const existingSessionId = localStorage.getItem("owdSessionId");
if (existingSessionId) {
    // Reconnect using the existing session ID
    reconnectToSession(existingSessionId);
}

we might need to do something like retain an active mapping of session tokens to device connections. This way, when a device reconnects, the server can match it with the correct peer. - but not sure how we would do this.

look at iceRestart

const offerOptions = { iceRestart: true };
const offer = await peerConnection.createOffer(offerOptions);
await peerConnection.setLocalDescription(offer);

oh also we would likely need to store other bits locally

const connectionDetails = {
    sessionId,
    signalingServer: "wss://your.signaling.server",
    webrtcConfig: { /* ICE servers, etc. */ },
};
localStorage.setItem("owdConnectionDetails", JSON.stringify(connectionDetails));

const savedDetails = localStorage.getItem("owdConnectionDetails");
if (savedDetails) {
    const { sessionId, signalingServer, webrtcConfig } = JSON.parse(savedDetails);
    reconnectToSession(sessionId, signalingServer, webrtcConfig);
}

All needs some careful thought and refactoring a bit..
