Calcite components

Calcite components, part of Esri's Calcite Design System, is a rich library of flexible, framework-agnostic web components for building applications. View the documentation for component descriptions, examples, and API reference, which includes properties, slots, styles, and theming.

Use the CDN

The most common approach for loading Calcite components is to use the version hosted on the CDN. The components can be loaded via <script> and <link> tags in the head of your HTML document:

<script
  type="module"
  src="https://cdn.jsdelivr.net/npm/@esri/calcite-components@3.1.0/dist/calcite/calcite.esm.js"
></script>

Once these tags are added, components can be used like any other HTML element. Only components that are used in the application will be loaded.

Use the NPM package

Refer to the Get started page for details on setting up the NPM package.

TypeScript

Refer to the Framework integration resource page for guidance on setting up TypeScript.
