By default bpmn-js has not pre-packaged library for bpmn-js-properties-panel or minimap or camunda-provider or etc… .
When I want to use this modules in my project, I have problem with non-pre-packaged libraries.
After hour’s I created a node-style-app with webpack bundler.
With this app, I create a pre-packaged library contain popular bpmn-js modules and now I able to use bpmn-js-properties-panel or any other modules in my project.
Now, you can fork this project from GitHub and use or develop it.
I hope this package help you.
