How to customize the appearance of task bars in XGantt?

XGantt provides style configuration through options like colors and gradients in the setup; however, since it's Canvas-based, CSS control is limited, and you may need to use the built-in styling APIs or external tools for advanced customization.

XGantt vs Frappe Gantt – which is better for performance?

XGantt uses Canvas for rendering, making it more performant with large datasets compared to SVG-based Frappe Gantt, but Frappe might offer easier styling and better accessibility out of the box. Choose based on your priority: speed or ease of customization.

Does XGantt support real-time data updates?

Yes, through its event system and update methods; you can dynamically change data and call render() or use the Vue/React adapters for reactive updates, but real-time collaboration features are not built-in and require manual implementation.

How to handle task dependencies with drag-and-drop in XGantt?

Enable the 'create' option in the links configuration, which allows visual drag-and-drop creation of dependency lines in the view, and listen to events like 'create:link' for custom logic integration as shown in the documentation.

Can I use XGantt with Angular?

While the core library is framework-agnostic, there's no official Angular adapter; you'll need to wrap it in an Angular component yourself, which adds integration complexity and may require handling lifecycle and data binding manually.

How to export XGantt charts to PDF or images?

XGantt doesn't have built-in export features; you'll need to use external libraries or Canvas APIs to capture the chart and convert it, which requires additional implementation effort for generating static outputs.

Use Cases

Best For

Adding interactive Gantt charts to project management software
Visualizing complex task dependencies and timelines in dashboards
Building custom project planning tools within web applications
Creating data-heavy timeline visualizations that require smooth performance
Integrating Gantt functionality into Vue 3 or React applications
Developing internal tools for resource allocation and progress tracking

Not Ideal For

Applications needing server-side rendering or static export of Gantt charts for PDFs
Teams using frameworks like Angular or Svelte without ready-made adapters

Pros & Cons

Pros

High-Performance Canvas Engine

Uses Konva.js for smooth Canvas-based rendering, efficiently handling large datasets without lag, as highlighted in the README's focus on performance for complex timelines.

Comprehensive Gantt Features

Includes task dependencies, multi-level structures, baselines, milestones, and virtual scrolling, covering most project management needs out of the box with minimal extra coding.

Framework-Agnostic Core

Works with any JavaScript framework, and provides dedicated, reactive adapters for Vue 3 and React, simplifying integration while maintaining flexibility.

Rich Event System

Offers extensive event hooks for clicks, drags, and updates, allowing deep customization of business logic, as shown in the API reference for event listening.

Cons

Accessibility Limitations

Canvas-based rendering makes it challenging to achieve full accessibility for screen readers without significant additional work, which the README does not address in detail.

Limited Framework Adapters

Official adapters are only available for Vue 3 and React, requiring custom integration for other popular frameworks like Angular, increasing setup effort for those ecosystems.

Configuration Overhead

The extensive options and event system necessitate a steep learning curve and detailed setup, which can be overwhelming for simpler use cases or rapid prototyping.
