How can I solve problem with require()?

See my answer to another question that has been asked a few days ago:

Integrate bpmn-js-properties-panel in web application

require is CommonJS module syntax (not to confuse with RequireJS). bpmn-js uses CommonJS modules so in order to run this code in the browser you must bundle it first. This is what this Grunt task is for in the example project. If you haven’t worked with these things before make sure to get familiar with CommonJS modules and how to bundle them for the browser (e.g. Browserify).
