Can I integrate Workflow Designer into an Angular or React app?

Yes, you can. In fact, Workflow Engine's Designer can be integrated into any HTML page, since it runs on JavaScript.

Examples:

  1. WorkflowEngine Designer for Angular Sample
  2. WorkflowEngine Designer for React Sample
  3. WorkflowEngine Designer for JavaScript Sample

Say you’ve got the following error:

__WEBPACK_IMPORTED_MODULE_3__external_workflowdesigner_min_js__ is not a constructor

Probably, that means that you tried to import the Workflow Designer like this:

import WorkflowDesigner from './scripts/workflowdesigner.min.js'

Please, don’t do that. It doesn't work, because WorkflowDesigner is defined as a global JS object. In order to integrate it into an Angular or React application, do the following:

  1. Include workflowdesigner.min.js and other libraries to your HTML page like this:

    <script src="/scripts/workflowdesigner.min.js" type="text/javascript"></script>
  2. Add a div with the id attribute to an Angular template or a render method in React:

    <div id="wfdesigner"></div>
  3. After it’s rendered, use the WorkflowDesigner global JS object (or window.WorkflowDesigner) like this:

    var wfdesigner = new WorkflowDesigner({
    name: 'simpledesigner',
    apiurl: '/Designer/API',
    renderTo: 'wfdesigner',
    imagefolder: '/Images/',
    graphwidth: 1200,
    graphheight: 600
    });

You can find more information on how to initialize WorkflowDesigner's JS object and required libraries here.

Besides, you can have a look at an example of integrating Workflow Designer into an Angular application on GitHub.

This sample uses the resources and the server-side of our demo stand available at workflowengine.io. You need to turn on CORS in your browser for the sample to work properly. You can do that via a Chrome extension. Use a search engine to look for solutions for other browsers.
