Hey HN! We've developed SVAR Svelte, an open-source component library that leverages Svelte's reactivity and performance to provide advanced UI widgets for complex applications. Our library focuses on delivering modular, customizable components that address real development challenges.

What’s included?

- Core Library - a collection of essential elements like buttons, modals, dropdowns, date picker, menu, tabs, etc.

- DataGrid - a feature-rich datagrid for managing large datasets with filtering, sorting, tree data view, frozen/collapsible columns, accessibility features, and virtual scrolling for best performance.

- Gantt - a Gantt chart component to visualize project timelines and dependencies with drag-and-drop interface, context menu, toolbar, tooltips, smooth zooming, and rich customization options.

- File Manager - a component that mimics a file browser user interface and can be linked to any server side.

- Editor - a handy component that helps to create editing forms for any structured elements on a page.

SVAR Svelte components are modular, customizable, and well-documented to help speed up development.
