FontAwesomeIcon component

Icon Prop

The basic FontAwesomeIcon can be called with three differents icon prop ways.

<FontAwesomeIcon icon='{faCoffee}' />
<FontAwesomeIcon icon='coffee' />
<FontAwesomeIcon icon={['fas', 'coffee']} />

The icon prop value can be:

  • a icon object, like {faCoffee}.
  • a string object, like coffee
  • an array {[“fas”, “coffee”]} where:
    • the first element is a prefix,
    • and the second element is the icon name:

Other Properties

Properties are called features

Example: Size where the icon size is relative to the current font-size.

<FontAwesomeIcon icon="spinner" size="xs" />

Import Usage

Explicit Import

Works out of the box with Javascript and typescript

import ReactDOM from 'react-dom'
import { FontAwesomeIcon } from '@fortawesome/react-fontawesome'
import { faCoffee } from '@fortawesome/free-solid-svg-icons'

const element = <FontAwesomeIcon icon={faCoffee} />

Implicit Import With Library

A library should created before an implicit import (where the icon are looked up by name).

import ReactDOM from 'react-dom'
import { library } from '@fortawesome/fontawesome-svg-core'
import { fab } from '@fortawesome/free-brands-svg-icons'
import { faCheckSquare, faCoffee } from '@fortawesome/free-solid-svg-icons'

library.add(fab, faCheckSquare, faCoffee)


  • with javascript (ie without typescript)
// All fab icon are available, then you can reference them directly
<FontAwesomeIcon icon={['fab', 'apple']} />

// The faCheckSquare, faCoffee where added, then you can reference them
// and the fas prefix (for Font Awesome Solid) is being inferred as the default. 
<FontAwesomeIcon icon="coffee" />
<FontAwesomeIcon icon="check-square" />
  • with typescript
import {
} from '@fortawesome/fontawesome-svg-core'

const coffeeLookup: IconLookup = { prefix: 'fas', iconName: 'coffee' }
const coffeeIconDefinition: IconDefinition = findIconDefinition(coffeeLookup)

// then object syntax
<FontAwesomeIcon icon={coffeeIconDefinition} />
