Load it from a CDN

Generate the library through the proper npm script, then host it and insert a <script> element into your page, specifying what elements should be converted in its data-selector attribute.

<script src="" data-selector="code"></script>

Or, if you need to separate process of loading/conversion, omit the data-selector attribute and use a second <script> element like this:

<script src=""></script>

document.addEventListener('DOMContentLoaded', function() {

You can also overwrite the server where the code will be sent to be compiled and analyzed (for example if you host a server instance that includes your own Kotlin libraries). For that you can set the data-server attibute, like this:

<script src=""

Fork & clone server repository.

Host your own instance

Install arrow-playground as dependency via NPM.

npm install arrow-playground -S

And then just use it in your code.

// ES5
var playground = require('arrow-playground');

document.addEventListener('DOMContentLoaded', function() {
  playground('code'); // attach to all <code> elements

// ES6
import playground from 'arrow-playground';

document.addEventListener('DOMContentLoaded', () => {
  playground('code'); // attach to all <code> elements
