    Getting started

    You can use threebox in three different ways.

    NPM install

    Add threebox to your project via npm package NPM version :

    npm install kongbox-plugin

    Then you will need to import Threebox object in your code. Depending your javascript framework this might be different.

    import { Threebox } from 'kongbox-plugin'; 

    Depending the framework, wrapper or bundler you ar using, try with this:

    import { Threebox } from 'kongbox-plugin/dist/threebox'; 

    Use the bundle locally

    Download the bundle from dist/threebox.js or dist/threebox.min.js and include it in a <script> tag on your page.
    If you want to use styles predefined, add the link to the cascade style sheet, just ensure the src and href attributes are pointing to relative or absolute url path.

    <script src="../dist/threebox.js" type="text/javascript"></script>
    <link href="../dist/threebox.css" rel="stylesheet" />

    Public CDNs

    Threebox can be also used from different public CDNs:


    This CDN has the particularity that always requires the version of the package to download individual files.

    <script src="" type="text/javascript"></script>
    <link href="" rel="stylesheet" />


    Despite this CDN admits version, if omitted, it will download always the last one published.

    <script src="" type="text/javascript"></script>
    <link href="" rel="stylesheet" />

    For an specific version (i.e. v2.2.1) use the followin:

    <script src="" type="text/javascript"></script>
    <link href="" rel="stylesheet" />

    Test the samples

    Several introductory examples are here.
    To run them, create a config.js file with your Mapbox-gl-js access token, alongside and in the format of the template.


    • Clone the Github repo.
    • Build the library with npm run build to get the minimized version, or npm run dev to get the development version and rebuild continuously as you develop.
    • Both commands will output a bundle in dist/ folder.

    Unit tests
