Acrolinx App SDK

Usage no npm install needed!

<script type="module">
  import acrolinxAppSdk from 'https://cdn.skypack.dev/@acrolinx/app-sdk';


Acrolinx App SDK

SDK for apps running inside of the Acrolinx Sidebar.


npm install @acrolinx/app-sdk

Example Code


import {RequiredCommands, RequiredEvents, DEVELOPMENT_APP_SIGNATURE, initApi} from '@acrolinx/app-sdk';

// Initialize the Acrolinx App API
const api = initApi({
  title: 'App Title',
  button: {
    text: 'Extract Text',
    tooltip: 'Extract text from the document'
  requiredCommands: [RequiredCommands.openWindow],
  requiredEvents: [RequiredEvents.textExtracted],

// Listen to events
api.events.textExtracted.addEventListener(textExtractedEvent => {
  console.log('textExtractedEvent', textExtractedEvent.text, textExtractedEvent.languageId);

// Execute commands

Plain old JavaScript

If you prefer to code in plain old JavaScript without npm and without a bundler, you can use the minified browser bundle. In this case you can find the SDK in the global namespace acrolinxAppSdk.

<script src="https://unpkg.com/@acrolinx/app-sdk/dist/acrolinx-app-sdk.min.js"></script>
  var api = acrolinxAppSdk.initApi({....

Please have a look at the corresponding live demo. Please note that this app does not do much when not loaded inside of an Acrolinx Sidebar.

App Icon

The app icon needs to be named by convention "acrolinx-app-icon.svg" and must put next to the app html file (example).

Demo Projects

  • Word Cloud (demonstrates text extraction and displays the results in a react word cloud component)
  • Select Ranges (demonstrates text extraction, select ranges and replace ranges)
