    A javascript api for

    Build Status

    Special notice

    This is a smaller version of DarkSkyJS that only deals with current (the currently endpoint) weather conditions, rather than the hourly and daily ones.

    The purpose of this version is to reduce the file size of the library and remove the dependencies, specifically:

    • Moment.JS, which could be considered quite large in proportion to the number of its features that are used
    • Promise polyfill, which is now supported in most browsers with the exception of IE11 and Opera Mini.


    This package is designed to provide:

    • A simple API for making multiple simultaneous requests
    • A promised-based request that only returns data when all requests are successful
    • A callback that outputs the data

    It differs from the original library in three ways:

    • It only accepts, and returns, arrays of locations/conditions - this is a breaking change
    • Each get function's name matches the property name of what the DarkSky service returns
    • Missing data points have been included, see Recent Updates seciton below:

    14/10/2019 In v0.1.0 there's improved error checking for the PROXY_SCRIPT URL - Invalid URLs now return warning. The response JSON is also checked for validity.

    The following data points have been added since 29/07/2017:

    • moonPhase
    • precipAccumulation
    • apparentTemperatureMax
    • apparentTemperatureMaxTime
    • apparentTemperatureMin
    • apparentTemperatureMinTime
    • precipIntensityMax
    • precipIntensityMaxTime
    • temperatureMaxTime
    • temperatureMinTime
    • uvIndex
    • uvIndexTime
    • windGust
    • windGustTime

    The following data points were added when first published on NPM

    • nearestStormDistance
    • nearestStormBearing

    Getting Started

    If you haven't already, create a developer account here

    It is recommended you install via NPM where dependencies will be loaded automatically.

    npm install darkskyjs

    darkskyjs is configured to work with both AMD and CJS applications.

    If you're using Webpack, Browserify or some other CJS module loader simply require the module like so

    var Darksky = require('darkskyjs');

    or using ES6 import, like so

    import Darksky from 'darkskyjs'

    and use the Darksky constructor like so:

    var darkSky = new DarkSky()

    You can then use the method listed below to retrieve location specific weather data.

    • getCurrentConditions

    If you're using Require.JS you will need to download momentjs and es6-promise.

    A server side proxy is required for this to work. So create a file that will contain your key and be careful not to commit it to a public code base.

    Here's an example PHP one. Replace the value of $api_key with your valid key.

    // File Name: proxy.php
    $api_key = 'b962d5ee80be5293a234b69fb975629c';
    $API_ENDPOINT = '';
    $url = $API_ENDPOINT . $api_key . '/';
    if(!isset($_GET['url'])) die();
    $url = $url . $_GET['url'];
    $url = file_get_contents($url);

    Location data

    darkskyjs can handle multiple location requests. Simply pass in an array of requests (to one of the three methods listed above) to get data for multiple locations.

    Each request must comprise of two key/value pairs: latitude and longitude. Optionally you can pass in a place name as a reference which will be returned should the request be successful e.g.

    [{latitude: 51.507351, longitude: -0.127758, name: 'London'}]

    If you don't pass an array it will create one for you, but it's best to do so for consistency and to avoid confusion as an array is what you'll get back.

    Returned data

    This API returns a set of functions that allow you to access the raw data, rather then the raw data itself. Each function is named in exactly the same way as its respective data point e.g. ozone() will return the value for ozone.

    getCurrentConditions returns an array of condition arrays. Each array represents one of locations you requested data for.

    In order to match the locations that were supplied with what's returned it is recommended that the name property be used. A callback is then used to supply the returned data. For example:

        // location object(s)
          latitude: 51.507351,
          longitude: -0.127758,
          name: 'London'
      // callback
      function(conditions) {
        for (var i = 0, length = conditions.length; i < length; i++) {
          if (conditions[i].name === 'London') {
