Creating streams:

You can create streamobjects with the following parameters:

Parameters:

Parameter	Function	Default
host	(Remote-) node we're connecting to.	0.0.0.0
port	Iota-api port on the node.	14265
id	Identifies the streamobject.	"SensorNode"
location	Nodes location, eg. 'lat': 52.26 'lng': 13.42.	{'lat': 40.65, 'lng': -73.91}
seed	Seed for creating transactions/MAM-messages.	[generated]
rec	Receiving address (tanglestream only).	"GPB9PBNCJTPGF..."
tag	Tag for Transactions (tanglestream only).	"SENSORNODEROCKS"
depth	Depth for tip-selection (tanglestream only).	3
wait	Discards packets till the current packet has been send.	true
fetch	Enable continuous fetching from MAM-root when multiple nodes stream from the same seed (mamstream only).	false

First Stream (TANGLE):

streams.push(new STREAM ({
  'host': 'http://[remote node / localhost]',
  'port':  [port]

  [OPTIONAL PARAMETERS]

}))

Second Stream (MAM):

streams.push(new MAM_STREAM ({
  'host': 'http://[remote node / localhost]',
  'port':  [port]

  [OPTIONAL PARAMETERS]

}))

Add data sources

Data sources are (async) functions which return the data you want to stream, eg:

async function functionFoo () {
	return await sensorA.read();
}
async function functionBar () {
	return await sensorB.read();
}

streams[0].addSource(functionFoo);
streams[1].addSource(functionBar);

Cool! Whats next?

Run with npm start [delay] where delay specifies a timeout between each push (default 60 seconds).

Thats it. Have fun providing data over the iota protocol. ;)
