Description

DHTMLX Gantt is a comprehensive jаvascript Gantt chart library designed to simplify project planning, automate scheduling, visualize critical paths, and manage resources efficiently for teams of any size.

Resource managementDHTMLX Gantt enables end-users to allocate multiple resources, like personnel and facilities, to projects and tasks. It also helps to adjust the assignments accurately with the help of various load charts and histograms.
Critical pathIt is possible to highlight the minimum duration of an entire project and determine the most vital tasks due to the built-in critical path calculation in DHTMLX Gantt. Moreover, the chart allows displaying the slack time and setting the lag and lead times.
Auto schedulingThe DHTMLX jаvascript Gantt chart library includes automatic scheduling functionality. If an end-user changes the duration of a particular task, the auto-scheduling extension updates all due dates automatically, taking into account task dependencies.
Node.js server moduleIt is an indispensable tool for external integration with complex CRM or ERP systems, real-time collaboration with many people working simultaneously on the same timeline, and clientless integrations with calculations based on calendars and links performed on the fly.
Drag and dropThe DHTMLX jаvascript Gantt chart supports diverse drag-and-drop operations. End-users can move several tasks, create tasks from scratch, and reorder columns in the grid with the help of drag and drop. Developers can control all the behavior via API.
The Community edition of DHTMLX Gantt is released under the MIT license and can be installed via npm. It simplifies prompting with GitHub Copilot or Claude to generate a usable starting point, which can then be adapted to real project requirements.
