Gantt editable chart for ReactJs
This one is really good too https://github.com/guiqui/react-timeline-ganttCan load thousands of records, has infinite scroll and task dependencies.
There is a gantt chart here which is ReactJS and open source (MIT) but as far as I can see not editable. But if you know ReactJS, making it editable would not be a huge job.
You can take a look at this React Gantt chart component made with the help of dhtmlxGantt (js gantt chart library): https://github.com/DHTMLX/react-gantt-demo
