Sample code​

Initialize the PubNub client API​

Required UUID

Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. If you don't set the UUID, you won't be able to connect to PubNub.

1let pubnub = new PubNub({
2    subscribeKey: "mySubscribeKey",
3    publishKey: "myPublishKey",
4    cipherKey: "myCipherKey",
5    authKey: "myAuthKey",
6    logVerbosity: true,
7    uuid: "myUniqueUUID",
8    ssl: true,
9    presenceTimeout: 130
10});

Returns​

It returns the PubNub instance for invoking PubNub APIs like publish(), subscribe(), history(), hereNow(), etc.

Other examples​

Configure using your own PubNub API keys​

1<div data-id="map"></div>
2<script>
3    let pn  = new PubNub({
4        subscribeKey : 'YOUR_SUB_KEY',
5        ssl : true
6    });
7    let channel = 'my-map';
8    let map = eon.map({
9        pubnub: pn,  // PubNub goes here
10        channels: channel,
11        id: 'map',
12        mbId 'mapbox.streets',
13        mbToken: 'pk.ey31IjoiaWRtc3giLCJhIjoiZZ1zMGI2ZjBlNTMxZjk5YTEwNjM5WNJlOWI4MmJiZGIifQ.U1jMQo2QVeuUtt85oD7hkQ'
14    });
15</script>

Marker customization​

You can supply a custom Mapbox marker object with custom tooltips by extening the L.marker object provided by mapbox. Learn more about custom markers here

Required UUID

Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. If you don't set the UUID, you won't be able to connect to PubNub.

1<div data-id='map'></div>
2<script>
3    L.RotatedMarker = L.Marker.extend({
4        options: { angle: 0 },
5        _setPos: function(pos) {
6            L.Marker.prototype._setPos.call(this, pos);
7            if (L.DomUtil.TRANSFORM) {
8                // use the CSS transform rule if available
9                this._icon.style[L.DomUtil.TRANSFORM] += ' rotate(' + this.options.angle + 'deg)';
10            } else if (L.Browser.ie) {
11                // fallback for IE6, IE7, IE8
12                let rad = this.options.angle * L.LatLng.DEG_TO_RAD,
13                costheta = Math.cos(rad),
14                sintheta = Math.sin(rad);
15                this._icon.style.filter += ' progid:DXImageTransform.Microsoft.Matrix(sizingMethod=\'auto expand\', M11=' +

Following a point​

You can tell the map to follow a point to it's new location whenever data is received by supplying a message callback.

Required UUID

Always set the UUID to uniquely identify the user or device that connects to PubNub. This UUID should be persisted, and should remain unchanged for the lifetime of the user or the device. If you don't set the UUID, you won't be able to connect to PubNub.

1let pn = new PubNub({
2    publishKey:   'YOUR_PUB_KEY', // replace with your own pub-key
3    subscribeKey: 'YOUR_SUB_KEY'  // replace with your own sub-key
4});
