react infinite grid is a React component which renders a grid of React elements. It's different because it only renders the elements that the user can see (and a small buffer) meaning that it is well suited for displaying a large number of elements.

npm install react-infinite-grid

The example below renders a grid with 100,000 items.

var React = require('react');
var InfiniteGrid = require('react-infinite-grid');

var Example = React.createClass({
	render: function() {
		return(
			<div className="example">
				This is {this.props.index}
			</div>
		);
	},
});

var items = [];
for (var i = 0; i <= 100000; i++) {
	items.push(<Example index={i} key={"example-" + i} />);
}

React.render(<InfiniteGrid wrapperHeight={400} entries={items} />, document.getElementById('grid'));

• entries React.PropTypes.arrayOf(React.PropTypes.element) - The only required property is an array of React elements that you want to render.

• height React.PropTypes.number - The height of the grid item
• width React.PropTypes.number - The width of the grid item
• padding React.PropTypes.number - The padding around your items
• wrapperHeight React.PropTypes.number - The height of the grid.
• lazyCallback React.PropTypes.func - A function that takes no arguments which is called when a user reaches the end of the grid. Useful if you want to lazy load your data.
