SVAR DataGrid is a powerful and flexible Svelte component for building high-performance, feature-rich data grids. Designed to handle large datasets efficiently, it supports virtual scrolling, inline editing, sorting, filtering, and full customization to fit complex project needs.

• High performance (virtual scrolling and dynamic loading)
• In-cell editing with different cell editors (datepicker, combo, select, rich select, etc.)
• Custom HTML for cells
• Sorting by multiple columns
• Filtering
• Paging
• Accessibility: compatibility with WAI-ARIA standard
• Frozen columns
• Expandable/collapsible columns
• Row reordering with drag-and-drop
• Customizable tooltips for grid cells
• Context menu
• External editor for grid data
• Tree-like structure
• Print support
• Keyboard navigation
• RestDataProvider for easy backend data binding
• Dark and light skins

There are two versions of the datagrid library: the 1.x version, designed to work with Svelte 4, and the 2.x version, created for Svelte 5.

To use the SVAR DataGrid for Svelte 5, install it as follows:

npm install wx-svelte-grid

To use the SVAR DataGrid for Svelte 4:

npm install wx-svelte-grid@1.3.3

To use SVAR DataGrid, simply import the package and include the component in your Svelte file:

<script>
	import { Grid } from "wx-svelte-grid";

	const data = [
		{
			id: 12,
			name: "Alex Brown",
			year: 1974,
		},
	];
	const columns = [
		{
			id: "name",
			header: "Title",
			flexgrow: 1,
			sort: true,
			editor: "text",
		},
		{
			id: "year",
			header: "Year",
			width: 100,
			sort: true,
			editor: "text",
		},
	];
</script>

<Grid {data} {columns} />

Typically, you don't need to modify the code. However, if you wish to do so, follow these steps:

1. Run yarn to install dependencies. Note that this project is a monorepo using yarn workspaces, so npm will not work
2. Start the project in development mode with yarn start

To run the test:

1. Start the test examples with:

   yarn start:tests

2. In a separate console, run the end-to-end tests with:

   yarn test:cypress
