A web component for rendering a long list of items without sacrificing performance.
<vaadin-virtual-list></vaadin-virtual-list>
<script>
const list = document.querySelector('vaadin-virtual-list');
list.items = items; // An array of data items
list.renderer = (root, list, { item, index }) => {
root.textContent = `#${index}: ${item.name}`;
};
</script>Install the component:
npm i @vaadin/virtual-listOnce installed, import the component in your application:
import '@vaadin/virtual-list';Vaadin components come with two built-in themes, Lumo and Material. The main entrypoint of the package uses the Lumo theme.
To use the Material theme, import the component from the theme/material folder:
import '@vaadin/virtual-list/theme/material/vaadin-virtual-list.js';You can also import the Lumo version of the component explicitly:
import '@vaadin/virtual-list/theme/lumo/vaadin-virtual-list.js';Finally, you can import the un-themed component from the src folder to get a minimal starting point:
import '@vaadin/virtual-list/src/vaadin-virtual-list.js';Read the contributing guide to learn about our development process, how to propose bugfixes and improvements, and how to test your changes to Vaadin components.
