Awaitable Import and Export APIs Land in bpmn-js

Published by Oguz Eroglu on Thursday, 28 May 2020.

bpmn-js7.0.0

We are happy to announce that the latest release of our BPMN modeling toolkit ships with Promise support for our async import and export APIs. Starting with this release users can benefit from async features available in modern, ES6-style JavaScript codebases as they await the API results. To align with our ongoing bpmn.io re-branding we ship an updated toolkit watermark, too.

This release brings promise support to our async toolkit APIs, allowing you to await the import or export results in a state-of-the-art manner:

const modeler = new BpmnModeler();

try {
  await modeler.importXML(bpmnDiagramXML);
} catch (err) {
  // handle import error
}

Callbacks style invocations are still supported but will be dropped in a future major release. We advise you to migrate to Promise-based API usage. Refer to this documentation to see with detailed examples what needs migration and what not. If you are still targeting Internet Explorer or Opera Mini, ensure you polyfill the global Promise object.

Promisified Import and Export APIs

You can now await these bpmn-js APIs:

Here's a small example of how to open a BPMN diagram in the new way.

const modeler = new BpmnModeler();

try {
  const {
    warnings
  } = await modeler.importXML(bpmnDiagramXML);

  console.log('Imported BPMN 2.0 diagram', warnings);
} catch (err) {

  const {
    warnings
  } = err;

  console.log('Failed to import BPMN 2.0 diagram', err, warnings);
}

Here is a small example of how to export a diagrams SVG in the new way.

try {
  const {
    svg
  } = await modeler.saveSVG();

  console.log('Exported BPMN 2.0 diagram in SVG format', svg);
} catch (err) {

  console.error(err);
}

For more examples, check by our our example repository for bpmn-js. It is already updated to feature the promisified APIs in action!
