lifx-node-wrapper v1.0.4

lifx-node-wrapper

Node.js Lifx HTTP API Wrapper

Features

• Promise based REST API calls
• Easy access to API responses
• Supports most LIFX HTTP API endpoints (more to be added)

Installation

Install lifx-node-wrapper with npm:

 $ npm install lifx-node-wrapper

To run this project, you will need a LIFX HTTP API key. Get your key here: https://api.developer.lifx.com/docs/authentication

Usage

Getting started

import Lifx from 'lifx-node-wrapper';

//create instance with our Lifx Token
var lifx = new Lifx(LIFX_KEY);

//lifx.<method> will now always use the key provided

Get list of all lights

Most functions require a selector to determine which lights to control. To stay consistent and avoid the package breaking, the wrapper uses standard LIFX selectors laid out in their documentation.

var lights = await lifx.ListLights('all')
console.log(lights.data);

//OR

lifx.ListLights('all')
    //grab returned data
    .then(data => {
        //handle data
        console.log(data)
    })
    .catch(err => 
        //handle errors
        console.log(err)
    );

Not using a parameter in a function

If you don't need a certain parameter, fill the spot with undefined. Note: selector and power are required if they are part of the function.

lifx.SetState('group_id:6a2e3...', 'on', undefined, 6.0, undefined, true)

You do not have to list undefined in every unused parameter.

lifx.SetState('group_id:6a2e3...', 'on')

API Reference

Get all items

lifx.ListLights()

Returns all available lights and their unique selectors. It's recommended to use their unique ID's instead of names like "Living Room" since the ID's will never change.

lifx.SetState()

lifx.TogglePower()

Turn off lights if any of them are on, or turn them on if they are all off.

lifx.ActivateScene()

Examples

Turn on a group of lights over 10 seconds with fast mode enabled

lifx.SetState('group_id:6a2e3...', 'on', undefined, 10.0, undefined, true)

//OR

//Note: no response is given in fast mode
lifx.SetState('group_id:6a2e3...', 'on', undefined, 10.0, undefined, true)
    .catch(err => 
        //handle errors
    );

Toggle all lights off/on

lifx.TogglePower('group_id:6a2e3...', 'on')

//OR

lifx.TogglePower('group_id:6a2e3...', 'on')
    //grab returned data
    .then(data => {
        //handle data
    })
    .catch(err => 
        //handle errors
    );

Activate a scene that was previously set-up in the LIFX app

lifx.ActivateScene('scene_id:1c4d3c7...338fa9', 1.0)

//OR

lifx.ActivateScene('scene_id:1c4d3c7...338fa9', 1.0)
    //grab returned data
    .then(data => {
        //handle data
    })
    .catch(err => 
        //handle errors
    );

Future Goals

• Add remaining API Endpoints

• Add additional error handling to improve usability

• Implement automated tests / checks using jest

📖 Feedback

I wrote this wrapper to use in my personal project to control my apartments smart devices through a custom Telegram Bot. LIFX lights had several nodejs libraries available, but few were up to date.

My goal was to not only to reduce outside dependencies in my own projects, but also make the API easier to use for others.

Writing this wrapper introduced me to javascript prototypes, classes, publishing NPM packages, and exporting/importing ES modules. Now to update my Telegram Bot to support this module...

Any and all feedback is appreciated.
