<iron-iconset-svg>

The iron-iconset-svg element allows users to define their own icon sets that contain svg icons.

Usage

Installation

npm install --save @polymer/iron-iconset-svg

In an HTML file

<html>
  <head>
    <script type="module">
      import '@polymer/iron-iconset-svg/iron-iconset-svg.js';
      import '@polymer/iron-icon/iron-icon.js';
    </script>
  </head>
  <body>
    <iron-iconset-svg name="inline" size="24">
      <svg>
        <defs>
          <g id="shape">
            <rect x="12" y="0" width="12" height="24"></rect>
            <circle cx="12" cy="12" r="12"></circle>
          </g>
        </defs>
      </svg>

    <iron-icon icon="inline:shape" role="img" aria-label="A shape"></iron-icon>
  </body>
</html>

In a Polymer 3 element

You can use an <iron-iconset-svg> anywhere you could put a custom element, such as in the shadow root of another component to expose icons to it. However, if you're going to be creating many instances of the containing component, you should move your <iron-iconset-svg> out to a separate module. This prevents a redundant <iron-iconset-svg> from being added to the shadow root of each instance of that component. See the demo (and specifically demo/svg-sample-icons.js) for an example.

import {PolymerElement} from '@polymer/polymer/polymer-element.js';
import {html} from '@polymer/polymer/lib/utils/html-tag.js';

import '@polymer/iron-iconset-svg/iron-iconset-svg.js';
import '@polymer/iron-icon/iron-icon.js';

class ExampleElement extends PolymerElement {
  static get template() {
    return html`
      <iron-iconset-svg name="inline" size="24">
        <svg>
          <defs>
            <g id="shape">
              <rect x="12" y="0" width="12" height="24"></rect>
              <circle cx="12" cy="12" r="12"></circle>
            </g>
          </defs>
        </svg>
      </iron-iconset-svg>

      <iron-icon icon="inline:shape" role="img" aria-label="A shape"></iron-icon>
    `;
  }
}

customElements.define('example-element', ExampleElement);
