enableiot-pump

Simple utility to push data to enableiot.com. The enableiot API is documented on GitHub.

Installation

npm install enableiot-pump

Usage

The enableiot-pump supports two usage patterns:

• Simple get data and submit results (single)
• Event-based subscription model (ongoing)

Simple

Simply setup the cloud client, retreave results from observation provider and submit:

// error handling and validation omitted for clarity 
cloud.setup(config, function(err, state){
    var observations = provider.get(state);
    cloud.submitObservations(state, observations, err_handler);
});

See examples for working example.

Event-based

When ongoing submission is required you can use the event-based pattern with subscription to the data event:

// error handling and validation omitted for clarity 
cloud.setup(config , function(err, state){
    provider.sub(state).on("data", function(observations){
      cloud.submitObservations(state, observations, err_handler);
    });
});

See examples for working example.

Provider

Both of these usage models are implemented using provider pattern. You can easily implement your own provider from Database, Message Queue or simply by tailing a log by implementing get and sub functions.

Get

var get = function(config){
    //TODO: Implement your code here
}

Sub

var sub = function(config){
    //TODO: Implement your code here
}

Both of these functions must return an array of observations.

Observation

Observation is a simple construct representing an event in time:

{
    "componentId": "my-registered-component-1",
    "on": 1406685882807,
    "value": "96.6"
}

The above object represents only the required elements. See enableiot documentation for more details about the supported types.

TODO

• Tests (yes please)
• DB, MQ, Log provider samples
