Have a MyScript developer account. You can create one here.
Get your keys and the free monthly quota to access MyScript Cloud at developer.myscript.com

Installation

iinkJS can be installed with the well known package managers npm, yarn.

If you want to use npm or yarn you first have to init a project (or use an existing one).

npm init
OR
yarn init

You can then install iinkJS and use it as showed in the Usage section.

npm install iink-js
OR
yarn add iink-js

Usage

Create an index.html file in the same directory.
Add the following lines in the head section of your file to use iinkJS and the css. We use PEP to ensure better browsers compatibilities. Note that you can also use it using dependencies from node_modules:

<script src="node_modules/iink-js/dist/iink.min.js"></script>
<script src="https://code.jquery.com/pep/0.4.3/pep.js"></script>

Still in the head section, add a style and specify the height and the width of your editor:

<style>
    #editor {
        width: 100%;
        height: 100%;
    }
</style>

In the body tag, create a div tag that will contain the editing area:

    <div id="editor"></div>

In JavaScript and within a <script> tag placed before the closing tag </body>, create the editor using the register function, your editor html element and a simple configuration:

  const editorElement = document.getElementById('editor');

  iink.register(editorElement, {
    recognitionParams: {
      type: 'TEXT',
      server: {
        applicationKey: '#YOUR MYSCRIPT DEVELOPER APPLICATION KEY#',
        hmacKey: '#YOUR MYSCRIPT DEVELOPER HMAC KEY#'
      }
    }
  });

Your index.html file should look like this:

<html>
    <head>
        <script src="node_modules/iink-js/dist/iink.min.js"></script>
        <script src="https://code.jquery.com/pep/0.4.3/pep.js"></script>
        <style>
            #editor {
                width: 100%;
                height: 100%;
            }
        </style>
    </head>
    <body>
        <div id="editor" touch-action="none"></div>
    <script>
        const editorElement = document.getElementById('editor');

        iink.register(editorElement, {
            recognitionParams: {
                type: 'TEXT',
                server: {
                    applicationKey: '#YOUR MYSCRIPT DEVELOPER APPLICATION KEY#',
                    hmacKey: '#YOUR MYSCRIPT DEVELOPER HMAC KEY#'
                }
            }
        });
    </script>
    </body>
</html>

Open index.html in your browser or serve your folder content using any web server.
