React Integration

This example demonstrates using vaadin-grid with React framework. - As React doesn't support custom attributes for elements, - vaadin-grid DOM API can't be fully utilized in the initialization.

Fortunately vaadin-grid also provides corresponding JavaScript APIs.

Note: vaadin-grid is not a React component. Instead, it must be - used with React like any JavaScript class. Please see the code example below or the - React documentation - for more information.
