@carbon/icon-helpers

Helpers used alongside icons for digital and software products using the Carbon Design System

Getting started

To install @carbon/icon-helpers in your project, you will need to run the following command using npm:

npm install -S @carbon/icon-helpers

If you prefer Yarn, use the following command instead:

yarn add @carbon/icon-helpers

Usage

@carbon/icon-helpers provides a couple of helpers for rendering <svg> nodes in a document, or to help get the correct attributes to set on an <svg> node. These include:

Name	Type	Description
getAttributes	(attributes: Object) => Object	Get the attributes for an <svg> node
formatAttributes	(attributes: Object) => String	Format the attributes into a string that can be applied to a node in the DOM
toString	(descriptor: Object) => String	Format the given icon descriptor into a string. Useful for templates
toSVG	(descriptor: Object) => DOMNode	Format the given icon descriptor into a DOM node

For most of the methods, attributes corresponds with whatever the name and value would be if you were writing the HTML for the <svg>. For example, if we wanted to set width and height we would do the following:

const { getAttributes } = require('@carbon/icon-helpers');
const attributes = getAttributes({ width: 20, height: 20 });

In order for the icon to be considered focusable, you will need to provide either aria-label or aria-labelledby in the given attributes in addition to tabindex. For example:

const { getAttributes } = require('@carbon/icon-helpers');
const attributes = getAttributes({
  'aria-label': 'My icon label',
  tabindex: '0',
});

Icon descriptors

An icon descriptor is the term we use to describe icon objects exported by @carbon/icons. By default, they will have the following shape:

{
  elem: 'svg',
  attrs: {
    xmlns: 'http://www.w3.org/2000/svg',
    viewBox: '0 0 16 16',
    width: 16,
    height: 16,
  },
  content: [
    {
      elem: 'path',
      attrs: {
        d: '...',
      },
    },
  ],
  name: 'IconName',
  size: 16,
}

You can import these definitions directly from @carbon/icons and use them alongside toSVG or toString by doing:

import { IconName } from '@carbon/icons';
import { toString, toSVG } from '@carbon/icon-helpers';

const iconString = toString(IconName);
const iconSVG = toSVG({
  ...IconName,
  attrs: {
    ...IconName.attrs,
    myCustomAttribute: 'myCustomAttributeValue',
  },
});
