Node.js fetch data from gantt chart without it being rendered.

On the backend of our application we would like to pass in a list of data and let the Gantt chart schedule it for us and then send back the scheduled JSON. Is there anyway to do this is node.js without rendering the actual Gantt chart?

Thank you!

const ganttObj = new gantt.Gantt({

  dataSource: dataManager,

  renderBaseline: true,


  taskFields: {

    id: 'taskId',

    name: 'taskName',

    startDate: 'startDate',

    endDate: 'endDate',

    duration: 'duration',

    expandState: 'isExpanded',

    child: 'children',

    dependency: 'predecessor',


  timelineSettings: {

    timelineViewMode: 'Month',


  treeColumnIndex: 1,




Essentially this in node.js​

Hi John,

Greetings from Syncfusion support.

We cannot perform the necessary calculations required for scheduling without rendering the Gantt Chart. However, we can hide the Gantt Chart using CSS. Then, you can pass the data to the Gantt Chart and then get the processed data from the Gant Chart’s dataBound event.




  #DefaultFunctionalities {

    display: none;






dataBound: function(args) {
