Install @fortawesome/fontawesome-svg-core and any icon packages you plan to use.
Then install the vue-fontawesome component:
# for Nuxt 2npm i --save @fortawesome/vue-fontawesome@latest-2
# for Nuxt 3npm i --save @fortawesome/vue-fontawesome@latest-3
# for Nuxt 2yarnadd @fortawesome/vue-fontawesome@latest-2
# for Nuxt 3yarnadd @fortawesome/vue-fontawesome@latest-3
Inside your Nuxt project add a plugins/fontawesome.js file:
// For Nuxt 2import Vue from'vue'import{ library, config }from'@fortawesome/fontawesome-svg-core'import{ FontAwesomeIcon }from'@fortawesome/vue-fontawesome'import{ fas }from'@fortawesome/free-solid-svg-icons'// This is important, we are going to let Nuxt.js worry about the CSS
config.autoAddCss =false// You can add your icons directly in this plugin. See other examples for how you// can add other styles or just individual icons.
library.add(fas)// Register the component globally
Vue.component('font-awesome-icon', FontAwesomeIcon)// Modify nuxt.config.js adding to the `css` and `plugins` sections.css:['@fortawesome/fontawesome-svg-core/styles.css']plugins:['~/plugins/fontawesome.js']
// For Nuxt 3import{ library, config }from'@fortawesome/fontawesome-svg-core'import{ FontAwesomeIcon }from'@fortawesome/vue-fontawesome'import{ fas }from'@fortawesome/free-solid-svg-icons'// This is important, we are going to let Nuxt worry about the CSS
config.autoAddCss =false// You can add your icons directly in this plugin. See other examples for how you// can add other styles or just individual icons.
library.add(fas)exportdefaultdefineNuxtPlugin((nuxtApp)=>{
nuxtApp.vueApp.component('font-awesome-icon', FontAwesomeIcon,{})})// Modify the `nuxt.config.ts` file by adding to the `export default defineNuxtConfig()`exportdefaultdefineNuxtConfig({css:['@fortawesome/fontawesome-svg-core/styles.css']})
Now you can add the icons using the syntax below wherever you want them to appear in your project.
If you use PurgeCSS(opens new window) with Nuxt 2 - or use the Nuxt tailwindcss module which comes with PurgeCSS prebundled - you need to add fontawesome CSS classes to the whitelist, Otherwise, PurgeCSS will treat them as unused and remove them since the classes only get inserted on rendering.
// For Nuxt 2 (Nuxt 3 is NOT supported by PurgeCSS at the time of writing this doc)// In your `nuxt.config.js`, add a purgeCSS config object.// You may adjust the regex to your liking:exportdefault{purgeCSS:{whitelistPatterns:[/svg.*/,/fa.*/]},}
This project and all Font Awesome SVG icons will work just fine in these components but we need to take an additional step to add the CSS correctly.
To take advantage of encapsulation that the Shadow DOM provides and to keep other areas of the DOM clean we need to add the Font Awesome CSS to the root of the Shadow DOM.
Here is an example that leverages the mounted() lifecycle hook to insert the CSS.
<script>import{ config, dom }from'@fortawesome/fontawesome-svg-core'import{ faCoffee, faStroopwafel, faDragon }from'@fortawesome/free-solid-svg-icons'import{ FontAwesomeIcon }from'@fortawesome/vue-fontawesome'// Make sure you tell Font Awesome to skip auto-inserting CSS into the <head>
config.autoAddCss =falseconst component ={name:'MyCustomElement',template:`<font-awesome-icon :icon="icon" />`,components:{
FontAwesomeIcon
},mounted(){// This will only work on your root Vue component since it's using $parentconst{ shadowRoot }=this.$parent.$options
const id ='fa-styles'if(!shadowRoot.getElementById(`${id}`)){const faStyles = document.createElement('style')
faStyles.setAttribute('id', id)
faStyles.textContent = dom.css()
shadowRoot.appendChild(faStyles)}},computed:{icon(){const icons =[faCoffee, faStroopwafel, faDragon]return icons[Math.floor(Math.random()*3)]}}}exportdefault component
</script>
