Package Exports
- getstats
- getstats/getStats
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (getstats) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

getStats.js | WebRTC getStats API
Single Page Demo or Multi User P2P Demo
A tiny JavaScript library using WebRTC getStats API to return peer connection stats i.e. bandwidth usage, packets lost, local/remote ip addresses and ports, type of connection etc.
It is MIT Licenced, which means that you can use it in any commercial/non-commercial product, free of cost.
npm install getstats
cd node_modules
cd getstats
node server.js
# and open:
# http://localhost:9999/To use it:
<script src="./node_modules/getstats/getStats.js"></script>Link the library
<script src="https://cdn.webrtc-experiment.com/getStats.js"></script>
<!-- or min.js -->
<script src="https://cdn.webrtc-experiment.com/getStats.min.js"></script>
<!-- or without CDN -->

<!-- or rawgit -->
<script src="https://rawgit.com/muaz-khan/getStats/master/getStats.js"></script>Or link specific build:
Or:
const getStats = require('getstats');
import { getStats} from 'getstats';Usage
var rtcPeerConnection = new RTCPeerConnection(rtcConfig);
var repeatInterval = 2000; // 2000 ms == 2 seconds
getStats(rtcPeerConnection, function(result) {
result.connectionType.remote.ipAddress
result.connectionType.remote.candidateType
result.connectionType.transport
result.bandwidth.speed // bandwidth download speed (bytes per second)
// to access native "results" array
result.results.forEach(function(item) {
if (item.type === 'ssrc' && item.transportId === 'Channel-audio-1') {
var packetsLost = item.packetsLost;
var packetsSent = item.packetsSent;
var audioInputLevel = item.audioInputLevel;
var trackId = item.googTrackId; // media stream track id
var isAudio = item.mediaType === 'audio'; // audio or video
var isSending = item.id.indexOf('_send') !== -1; // sender or receiver
console.log('SendRecv type', item.id.split('_send').pop());
console.log('MediaStream track type', item.mediaType);
}
});
}, repeatInterval);Safari?
var audioTrack = stream.getTracks().filter(function(t) {
return t.kind === 'audio';
});
getStats(peer, audioTrack, function(results) {
// rest goes here
}, 5 * 1000);result.datachannel
// states => open or close
alert(result.datachannel.state === 'open');result.isOfferer
Offerer is the person who invoked createOffer method.
result.encryption
To detect which tech is used to encrypt your connections.
alert(result.encryption === 'sha-256');result.nomore()
This function can be used to ask to stop invoking getStats API.
btnStopGetStats.onclick = function() {
getStatsResult.nomore();
};result.bandwidth
You can use result.bandwidth.speed to detect your system's available download speed.
