DHTMLX React Gantt XState Demo

This project demonstrates how to integrate the DHTMLX React Gantt component with XState for state management in a React application. The integration enables centralized control of Gantt chart data, tasks, and links, providing predictable updates and smooth UI interactions through a state machine architecture. The setup uses React 19+ and Vite, with full TypeScript support for enhanced code quality and maintainability.

Features:

• Powerful Gantt chart UI for project planning and task management.

• Task and link creation, update, and deletion managed through XState machine actions.

• React component driven approach with props controlling Gantt configuration.

• Seamless XState integration for predictable and powerful state management with state machines.

• Support for zoom levels (day, month, year), undo/redo operations, and drag-and-drop functionality.

• Interactive toolbar with Material-UI components for enhanced user experience.

• Strong TypeScript support for type-safe usage.
