Installation

If you're using Ionic Framework, Ionicons is packaged by default, so no installation is necessary. Want to use Ionicons without Ionic Framework? Place the following <script> near the end of your page, right before the closing </body> tag, to enable them.

<script type="module" src="https://unpkg.com/ionicons@7.1.0/dist/ionicons/ionicons.esm.js"></script>
<script nomodule src="https://unpkg.com/ionicons@7.1.0/dist/ionicons/ionicons.js"></script>

Basic usage

To use a built-in icon from the Ionicons package, populate the name attribute on the ion-icon component:

<ion-icon name="heart"></ion-icon>
