emotion-icons

emotion-icons is a fork from emotion-icons that uses emotion instead of styled-components.

react-emotion provides the Font Awesome, Feather, Material Design, and Octicons icon packs as emotion-js, with full support for TypeScript types and tree-shaking / ES modules.

Installation

yarn add react-emotion

or

npm install react-emotion --save

Additionally, you will need to have installed a version of react-emotion, as emotion-icons depends on react-emotion as a peer dependency.

Usage

All Font Awesome (free), Feather, Material, and Octicon icons are available for preview at the Icon Explorer.

The entire icon packs are available via the main import and sub-imports:

import {material, octicons} from 'emotion-icons'

import * as faBrands from 'emotion-icons/fa-brands'
import * as faRegular from 'emotion-icons/fa-regular'
import * as faSolid from 'emotion-icons/fa-solid'
import * as feather from 'emotion-icons/feather'
import * as material from 'emotion-icons/material'
import * as octicons from 'emotion-icons/octicons'

The icons are also available as individual imports - it is recommended that you import icons individually using ES modules along with a module bundler like Webpack or Rollup in order to enable tree-shaking. This means that the module bundler will remove unused icons from the final JavaScript bundle, saving bandwidth and speeding up loading:

import React, {Fragment} from 'react'
import {Account, Lock} from 'emotion-icons/material'

const App = () => (
  <Fragment>
    <Account />
    <Lock />
  </Fragment>
)

Props

Styled Icons accept all the valid props of an <svg /> element, in addition to the following custom props:

Prop	Required	Type	Description
size	optional	string, number	This is a convenience for setting both width and height to the same value
title	optional	string	This sets the icon title and enables the standalone icon accessability mode. See accessibility below for additional details
css	optional	string, function, css tagged template literal	This prop accepts additional CSS to attach to the icon. It accepts the CSS as a string or as any valid Style Components interpolation

Example

import React from 'react'
import {Lock} from 'emotion-icons/material'

const App = () => <Lock size="48" title="Unlock account" css="color: red;" />

Icon Dimensions

Some icons natively have non-square dimensions - original dimensions are exported from the individual icon exports:

import {LogoGithub, LogoGithubDimensions} from 'emotion-icons/octicons/LogoGithub'

const App = () => <LogoGithub />

console.log(LogoGithubDimension) // {height: 16, width: 45}

Dimension exports are not available on the icon pack or index exports:

import * as octicons from 'emotion-icons/octicons'
import {octicons} from 'emotion-icons'

// octicons contains only icon exports

Styled Components

All icons are exported as Styled Components, which means it is possible to utilize the Styled Components API:

import styled from 'emotion-components'
import {Lock} from 'emotion-icons/material'

export const RedLock = styled(Lock)`
  color: red;

  font-weight: ${props => (props.important ? 'bold' : 'normal')};
`

Accessibility

Styled Icons have two different built-in "modes" for accessibility purposes. By default, icons are considered decorative, meaning the icon is just visual sugar and the surrounding content is sufficient for conveying meaning. This will set the aria-hidden attribute on the resulting HTML to hide the icon from screen readers.

// this icon
<Lock />

// will result in
<svg aria-hidden="true">...</svg>

Alternatively the icon could be used in standalone mode, meaning the icon itself should convey meaning. This mode is enabled by setting a title prop - this is the text that will be read by a screen reader. This results in role being set to img and the addition of a <title> element.

// this icon
<Lock title="Lock account" />

// will result in
<svg role="img"><title>Lock account</title> ...</svg>

Since Style Icons accept all <svg> element attributes as props, you are free to override these aria-* attributes if you have a more complex use-case.

As this library provides direct access to the <svg> element, you may wish to further wrap the icon for additional semantic meaning. For example, for a loading spinner:

import styled from 'emotion-components'
import {Spinner} from 'emotion-icons/fa-solid/Spinner'

const VisuallyHidden = styled.span`
  border: 0 !important;
  clip: rect(1px, 1px, 1px, 1px) !important;
  height: 1px !important;
  overflow: hidden !important;
  padding-top: 0 !important;
  padding-right: 0 !important;
  padding-bottom: 0 !important;
  padding-left: 0 !important;
  position: absolute !important;
  white-space: nowrap !important;
  width: 1px !important;
`

<span title="Loading posts..." role="alert" aria-live="assertive">
  <Spinner />
  <VisuallyHidden>Loading posts...</VisuallyHidden>
</span>

Tree Shaking

NOTE: tree shaking should work without modification using Create React App.

Tree shaking has been tested with Create React App, Rollup, and Webpack. If your bundler is unable to import the icons, additional CommonJS bundles are available as .cjs:

import React, {Fragment} from 'react'

// This will result in all Material icons being bundled
import {Account} from 'emotion-icons/material.cjs'

// This will only include the Lock icon
import {Lock} from 'emotion-icons/material/Lock.cjs'

const App = () => (
  <Fragment>
    <Account />
    <Lock />
  </Fragment>
)

Be aware though that importing from the CommonJS icon pack bundles will likely result in significantly larger bundle sizes, because unused icons will be included in the final bundle. If you are unable to configure your bundler to process the ES module bundles, you should import icons individually to avoid large bundles.
