Starting with dmn-js@8 the library displays and saves DMN 1.3 diagrams only. To open older DMN files, migrate them before loading them with dmn-js.

dmn-js - DMN for the web

View and edit DMN 1.3 diagrams in the browser.

Installation

Use the library pre-packaged or include it via npm into your node-style web-application.

Usage

To get started, create a dmn-js instance and render DMN 1.3 diagrams in the browser:

var xml; // my DMN 1.3 xml
var viewer = new DmnJS({
  container: 'body'
});

viewer.importXML(xml, function(err) {

  if (err) {
    console.log('error rendering', err);
  } else {
    console.log('rendered');
  }
});

Checkout our examples for more supported usage scenarios.

Dynamic Attach/Detach

You may attach or detach the viewer dynamically to any element on the page, too:

var viewer = new DmnJS();

// attach it to some element
viewer.attachTo('#container');

// detach the panel
viewer.detach();
