Lifx HTTP Api Node.js Wrapper

A thin Node.js API wrapper of the Lifx HTTP protocol.

This library is not, in any way, affiliated or related to Lifi Labs, Inc.. Use at your own risk.

Installation

$ npm install lifx-http-api --save

Compatibility

Node.js 4.2.6+ is tested and supported on Mac, Linux and Windows.

Bearer Token

A bearer token is mandatory to use the API. A new token can be obtain in the Lifx Cloud Settings.

Usage

The thin API wrapper uses a client for network communication. This client handles all requests against the Lifx API.

var lifx = require('lifx-http-api'),
    client;
    
client = new lifx({
    bearerToken: '<your api token>'
});

The Client object provides promises by the great Q library. You can either use callbacks or promises.

// Using callbacks
client.listLights('all', function(err, data) {
    if(err) {
    	console.error(err);
    	return;
    }
    
    console.log(data)
});

// Using promises
client.listLights('all').then(console.log, console.error);

Getting lights and scenes

client.listLights(selector, [cb])

Gets lights belonging to the authenticated account. Filter the lights using selectors.

Option	Type	Default	Description
selector	string		Selector for the light bulb you want to get. See the Selector section to get more information.
cb	function	null	function(err, data) {} Callback function which will be called when the HTTP request to the API was processed.

Usage example:

// Using callbacks
client.listLights('all', function(err, data) {
    if(err) {
    	console.error(err);
    	return;
    }
    
    console.log(data)
});

// Using promises
client.listLights('all').then(console.log, console.error);

Modifying light state

client.setState(selector, settings, [cb])

Sets the state of the lights within the selector.

Option	Type	Default	Description
selector	string		Selector for the light bulb you want to get. See the Selector section to get more information.
settings	object	{}	State configuration object. See the official documentation for further information.

}, function(err, data) {
    if(err) {
    	console.error(err);
    	return;
    }
    
    console.log(data)
