Octicons for React

Install

$ npm install @primer/octicons-react --save

Usage

Icons

The @primer/octicons-react module exports the individual icon components as separate files. This allows you to import only the icons that you need without blowing up your bundle:

import React from 'react'
import Beaker from '@primer/octicons-react/Beaker';
import Zap from '@primer/octicons-react/Zap';

export default function Icon({boom}) {
  return boom ? <Zap /> : <Beaker />
}

<Octicon>

The <Octicon> component is exported as default from @primer/octicons-react and is really just the "shell" of an Octicon that renders the <svg> element and all of its attributes. Note that all icons are automatically wrapped in this component.

Vertical alignment

By default the octicons have vertical-align: text-bottom; applied as inline styles. You can change the alignment via the verticalAlign prop, which can be either middle, text-bottom, text-top, or top.

import Repo from '@primer/octicons-react/Repo'

export default () => (
  <h1>
    <Repo size='large' verticalAlign='middle' /> github/github
  </h1>
)

ariaLabel

You have the option of adding accessibility information to the icon with the aria-label attribute via the ariaLabel prop (note the capitalization of L!).

// Example usage
import Plus from '@primer/octicons-react/Plus'

export default () => (
  <button>
    <Plus ariaLabel="Add new item" /> New
  </button>
)

Sizes

The size prop takes small, medium, and large values that can be used to render octicons at standard sizes:

// Example usage
import LogoGithub from '@primer/octicons-react/LogoGithub'

export default () => (
  <h1>
    <a href='https://github.com'>
      <LogoGithub size='large' ariaLabel='GitHub'/>
    </a>
  </h1>
)

Custom icons

Each of our icon components is really just a function that renders its SVG <path>. To accommodate icons varying aspect ratios, the Octicon component determines the viewBox of the <svg> element by first looking for a size array on the icon component class. For instance, if you wanted to create a custom icon that consisted of three circles side by side, you could do this:

import React from 'react'
import Octicon from '@primer/octicons-react'

function CirclesIcon() {
  return (
    <React.Fragment>
      <circle r={5} cx={5} cy={5}/>
      <circle r={5} cx={15} cy={5}/>
      <circle r={5} cx={25} cy={5}/>
    </React.Fragment>
  )
}

CirclesIcon.size = [30, 10]

export default CirclesOcticon(props) {
  return <Octicon {...props} icon={CirclesIcon} />
}
