zeekay f29f9e7c6e State a version once
A version written into a manifest is written into every manifest that wants it,
which is how eslint came to exist in a hundred and four forms across this estate
and how a package came to resolve twice at run time. The catalog moves the number
out of the manifest: a manifest names the package, the workspace names the
version.

Four are held below their latest because the newer release cannot be used, and
the reason is recorded rather than the version alone: @noble/hashes 2 renamed
every subpath the web3 stack imports, @splinetool/runtime 2 depends on a package
that was never published, @dynamic-labs 5.4.1 the same, and react-resizable-panels
3 points its types condition at the bundle.

Instructions

Record side

// Record side

import rrweb from '@insights/rrweb';
import { RRWebPluginCanvasWebRTCRecord } from '@insights/plugin-canvas-webrtc-record';

const webRTCRecordPlugin = new RRWebPluginCanvasWebRTCRecord({
  signalSendCallback: (msg) => {
    // provides webrtc sdp offer signal & connect message
    // make sure you send this to the replayer's `webRTCReplayPlugin.signalReceive(signal)`
    sendSignalToReplayer(msg); // example of function that sends the signal to the replayer
  },
});

rrweb.record({
  emit: (event) => {
    // send these events to the `replayer.addEvent(event)`, how you do that is up to you
    // you can send them to a server for example which can then send them to the replayer
    sendEventToReplayer(event); // example of function that sends the event to the replayer
  },
  plugins: [
    // add the plugin to the list of plugins, and initialize it via `.initPlugin()`
    webRTCRecordPlugin.initPlugin(),
  ],
  recordCanvas: false, // we don't want canvas recording turned on, we're going to do that via the plugin
});

Replay Side

// Replay side
import rrweb from '@insights/rrweb';
import { RRWebPluginCanvasWebRTCReplay } from '@insights/plugin-canvas-webrtc-replay';

const webRTCReplayPlugin = new RRWebPluginCanvasWebRTCReplay({
  canvasFoundCallback(canvas, context) {
    console.log('canvas', canvas);
    // send the canvas id to `webRTCRecordPlugin.setupStream(id)`, how you do that is up to you
    // you can send them to a server for example which can then send them to the replayer
    sendCanvasIdToRecordScript(context.id); // example of function that sends the id to the record script
  },
  signalSendCallback(signal) {
    // provides webrtc sdp offer signal & connect message
    // make sure you send this to the record script's `webRTCRecordPlugin.signalReceive(signal)`
    sendSignalToRecordScript(signal); // example of function that sends the signal to the record script
  },
});

const replayer = new rrweb.Replayer([], {
  UNSAFE_replayCanvas: true, // turn canvas replay on!
  liveMode: true, // live mode is needed to stream events to the replayer
  plugins: [webRTCReplayPlugin.initPlugin()],
});
replayer.startLive(); // start the replayer in live mode

replayer.addEvent(event); // call this whenever an event is received from the record script
