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@3.0.2/dist/calcite/calcite.esm.js"
></script>
<link
  rel="stylesheet"
  type="text/css"
  href="https://cdn.jsdelivr.net/npm/@esri/calcite-components@3.0.2/dist/calcite/calcite.css"
/>

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

Calcite Components is also provided as an NPM package. To get started, first install the package, then follow the steps below. Alternatively, you can find examples using different frameworks and build tools here.

npm install @esri/calcite-components

1. Build

Refer to the Get started page for details on setting up a build.

2. Assets

Some components, such as calcite-icon and calcite-date-picker, rely on assets being available at a particular path. As mentioned, with the NPM package you have the option to provide a local path or the URL to the assets hosted on the CDN. Using the CDN hosted assets can help decrease on disk build size.

To use the assets locally, they need to be copied using a build tool or NPM script. The directory for the local assets must be named assets, which eases the copying process. For example, /public/calcite/assets will work, however /public/calcite-assets will not.

The Calcite Components examples repo demonstrates using local assets in a variety of JavaScript frameworks and build tools. Each example has a README with a framework or build tool specific explanation.

cp -r node_modules/@esri/calcite-components/dist/calcite/assets/* ./public/assets/

3. Styles

Finally, load the Cascading Style Sheet (CSS). This is also dependent on your framework or build tool, however in many cases it can be imported in JavaScript:

import "@esri/calcite-components/dist/calcite/calcite.css";

TypeScript

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