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:

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

try {
  const { warnings } = await viewer.importXML(xml);

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

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:

const viewer = new DmnJS();

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

// detach the panel
viewer.detach();

Resources

Building the Project

Perform the following steps to build the library, including running all tests:

npm install
npm run all

Run tests in individual packages:

npm run dev -- dmn-js

dmn-js builds on top of a few additional powerful tools:

dmn-moddle: Read / write support for DMN 1.3 XML
diagram-js: Diagram rendering and editing toolkit
table-js: Table rendering and editing toolkit
