Lelylan API for Node.js

Node.js client library for Lelylan API.

What is Lelylan

Lelylan makes it easy for developers to monitor and control all devices in your house providing a simple, self descriptive and consistent representation of them. Lelylan maps every device in your house to a unique URI which will provide a simple access over it.

With Lelylan developers can build secure applications and services that use real-time data coming from the real world to create the future connected house.

Requirements

Node client library is tested against Node ~0.8.x

Installation

Install the client library using npm:

$ npm install lelylan-node
$ npm install simple-oauth2

Install the client library using git:

$ git clone git://github.com/lelylan/lelylan-node.git
$ cd lelylan-node
$ npm install

Getting started

Get an access token

Before calling Lelylan APIs you need to set the access token using Simple OAuth2. If not used to OAuth2 concepts, check out the dev center documentation.

// Set the client credentials and the OAuth2 server
var credentials = {
  clientID: '<client-id>',
  clientSecret: '<client-secret>',
  site: 'http://people.lelylan.com'
};
 
// Initialize the OAuth2 Library
var OAuth2 = require('simple-oauth2')(credentials);
 
// Authorization OAuth2 URI
// See available scopes here http://localhost:4000/api/oauth#scopes
var authorization_uri = OAuth2.AuthCode.authorizeURL({
  redirect_uri: '<redirect-uri>',
  scope: '<scopes>',
  state: '<state>'
});
 
console.log('Auhtorization URI', authorization_uri);
// => http://people.lelylan.com/oauth/authorize?
//      redirect_uri=<redirect-uri>&
//      scope=<scopes>&response_type=code&client_id=<client-id>
 
// Redirect example using Express (see http://expressjs.com/api.html#res.redirect)
res.redirect(authorization_uri);
 
// Get the access token object (authorization code is given from the previous step)
var token;
OAuth2.AuthCode.getToken({
  code: '<code>',
  redirect_uri: '<client-id>'
}, function(error, result) {
  // Save the access token
  if (error) console.log('Access Token Error', error.message);
  token = OAuth2.AccessToken.create(result);
  console.log('Access Token', token);
});

Lelylan access

Once you have the access token you can access to the Lelylan API. The following example shows how to print in the console a list of owned devices.

// Initialize Lelylan Node library
var Lelylan = require('lelylan-node')({ token: token });
 
// Get all devices
Lelylan.Device.all({}, function(error, response) {
  if (error) console.log('Lelylan Error', error.message);
  console.log(response);
  console.log(response.uri);
  console.log(response.properties[0].value);
});

Using a Simple OAuth2 AccessToken, the access token is automatically refreshed when it expires.

Realtime services

When using the subscription services (realtime) you don't need an access token. In this case you need to set the client credentials.

// Setup credentials
credentials = { clientID: '<client-id>', clientSecret: '<client-secret>' };
Lelylan = require('lelylan-node')(credentials);
 
// Get all subscriptions
Lelylan.Subscriptions.all(function(error, response) {
  if (error) console.log('Lelylan Error', error.message);
  console.log(response)
})

Implemented Services

• Devices.
• Activations.
• Histories.
• Types.
• Properties.
• Functions.
• Statuses.
• Locations.
• Physical devices.
• Subscriptions.
• User Profile.
• OAuth2.

Errors

Exceptions are raised when a 4xx or 5xx status code is returned.

HTTPError

Through the error message attribute you can access the JSON representation made by the HTTP status and an error message.

Lelylan.Device.all({}, function(error, response) {
  if (error) console.log('Lelylan Error', error.message.message);
})

The error.message object contains the status and the message properties. 401, 403, 404, 422 responses has also a valid response object. Learn more about errors on Lelylan.

Configurations

Lelylan Configuration accepts an object with the following valid params.

• token - A Simple OAuth2 AccessToken object.
• clientID - A string that represents the registered Client ID.
• clientSecret - A string that represents the registered Client secret.
• endpoint - A string that represents the API endpoint (api.lelylan.com by deafault).

Here a simple example where we change the API endpoint.

options = { 'endpoint' : 'http://localhost:8000' }
Lelylan = require('lelylan')(options);

To directly access to the config object use the #config method.

var rawToken = Lelylan.config.token.token
