new SiRuClient(roomName, options)

Client class of SkyWay IoT Room Utility

Param	Type	Description
roomName	string	The name of the room.
options	Object	option argument of skyway constructor. For more detail, please check https://webrtc.ecl.ntt.com/en/js-reference/Peer.html.
options.key	string	SkyWay API key. This is only one mandatory parameter in options.

Example

const client = new SiRuClient( 'testroom', { key: 'YOUR_API_KEY' } );

client.on('connect', () => { ... });

siRuClient.publish(topic, data)

publish message to all connecting peer. when subscribing by myself, fire ‘message’ event internally as well.

Kind: instance method of SiRuClient

Param	Type
topic	string
data	string | object

Example

client.publish('testtopic/message', {payload: 'hello'});

siRuClient.subscribe(topic)

subscribe to topic

Kind: instance method of SiRuClient

Param	Type
topic	string

Example

client.subscribe('testtopic/+');
client.on('message', ( topic, name ) => {
  console.log(topic, name); // #=> 'testtopic/message hello'
});

siRuClient.unsubscribe(topic)

unsubscribe topic

Kind: instance method of SiRuClient

Param	Type
topic	string

Example

client.unsubscribe('testtopic/+');

siRuClient.requestStreaming(uuid) ⇒ Promise.<Object>

request streaming to SSG

Kind: instance method of SiRuClient
Returns: Promise.<Object> - returns stream object

Param	Type
uuid	string

Example

client.requestStreaming(uuid)
  .then( stream => { ... } )

siRuClient.stopStreaming(uuid) ⇒ Promise.<void>

request stop streaming to SSG

Kind: instance method of SiRuClient

Param	Type
uuid	string

stream	Object		media stream object
[options]	Object
[options.audioCodec]	string	"'opus'"	audio codec
[options.videoCodec]	string	"'H264'"	video codec

Example

const client = new SiRuClient( 'testroom', { key: 'YOUR_API_KEY' } );

client.on('meta', profile => {
  navigator.mediaDevices.getUserMedia({ audio: true, video: false })
    .then( stream =>
       client.sendStream( profile.uuid, stream )
    )
    .then( call => console.log('start sending local stream') )
    .catch( err => console.warn(err) );
});
