Install

npm install @primer/octicons-react

Usage

Icons

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

import React from 'react'
import {BeakerIcon, ZapIcon} from '@primer/octicons-react'

export default function Icon({boom}) {
  return boom ? <ZapIcon /> : <BeakerIcon />
}

If you were to compile this example with a tool that supports tree-shaking (such as Webpack, Rollup, or Parcel) the resulting bundle would only include the "zap" and "beaker" icons.

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 {RepoIcon} from '@primer/octicons-react'

export default () => (
  <h1>
    <RepoIcon verticalAlign="middle" /> github/github
  </h1>
)

aria-label

You have the option of adding accessibility information to the icon with the aria-label attribute via the aria-label prop.

// Example usage
import {PlusIcon} from '@primer/octicons-react'

export default () => (
  <button>
    <PlusIcon aria-label="Add new item" /> New
  </button>
)

aria-labelledby

You have the option of adding accessibility information to the icon with the aria-labelledby attribute via the aria-labelledby prop. Using aria-labelledby referencing the id values of the title element provides the accessible name.

// Example usage
import {PlusIcon} from '@primer/octicons-react'

export default () => (
  <button>
    <PlusIcon aria-labelledby="title" title="Add new item" /> New
  </button>
)

title

You have the option of adding accessibility information to the icon with the title attribute via the title prop.

id

You have the option of adding information to the icon with the id attribute via the id prop.

// Example usage
import {PlusIcon} from '@primer/octicons-react'

export default () => (
  <button>
    <PlusIcon id="unique-plus-icon" /> New
  </button>
)

tabIndex

You can add the tabindex attribute to an SVG element via the tabIndex prop if the SVG element is intended to be interactive. tabIndex prop also controls the focusable attribute of the SVG element which is defined by SVG Tiny 1.2 and only implemented in Internet Explorer and Microsoft Edge.

If there is no tabIndex prop is present (default behavior), it will set the focusable attribute to false. This is helpful for preventing the decorative SVG from being announced by some specialized assistive technology browsing modes which can get delayed while trying to parse the SVG markup.

// Example usage
import {PlusIcon} from '@primer/octicons-react'
export default () => (
  <PlusIcon aria-label="Interactive Plus Icon" tabIndex={0} /> New Item
)

Sizes

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

Prop	Rendered Size
size='small'	16px height by computed width
size='medium'	32px height by computed width
size='large'	64px height by computed width

// Example usage
import {LogoGithubIcon} from '@primer/octicons-react'

export default () => (
  <h1>
    <a href="https://github.com">
      <LogoGithubIcon size="large" aria-label="GitHub" />
    </a>
  </h1>
)

Fill

The fill prop takes a string value that can be used to set the color of the icon. By default, fill is set to currentColor.

// Example usage
import {LogoGithub} from '@primer/octicons-react'
export default () => (
  <h1>
    <a href="https://github.com">
      <LogoGithubIcon fill="#f00" />
    </a>
  </h1>
)

- <Octicon icon={AlertIcon} />
+ <AlertIcon />

The Octicon component is wrapper that passes props to its icon component. To render a specific icon, you can pass it either via the icon prop, or as the only child:

<Octicon icon={Icon} />
<Octicon><Icon x={10}/></Octicon>
