Laravel font defined by locale

How can I define font-family for my app based on user locale?

Let say user switch to ID then I change font-family of my site body.

app.scss

As of sample I’ve added 3 fonts and try to use each of them based on selected locale

//use for "en"
@font-face {
  font-family: Nunito;
  src: url('/fonts/Nunito/Nunito-Regular.ttf');
}
//use for "id"
@font-face {
  font-family: Righteous;
  src: url('/fonts/Righteous/Righteous-Regular.ttf');
}
// use for "fa"
@font-face {
  font-family: Dirooz;
  src: url('/fonts/dirooz/Dirooz.ttf');
}

any idea?

Answer

You can do it from within the Vue component triggering another method when the user selects a locale

Assume that you have @font-face defined in your css for all three

@font-face {
  font-family: Nunito;
  src: url('/fonts/Nunito/Nunito-Regular.ttf');
}
//use for "id"
@font-face {
  font-family: Righteous;
  src: url('/fonts/Righteous/Righteous-Regular.ttf');
}
// use for "fa"
@font-face {
  font-family: Dirooz;
  src: url('/fonts/dirooz/Dirooz.ttf');
}

Then in the Vue component

setFontFamily() {    
    let styleTags = document.querySelectorAll('style');
    if(this.initialStyleTagsCount < styleTags.length) {
        //Remove the previous style tag
        let lastStyle = styleTags[styleTags.length - 1];
        document.head.removeChild(lastStyle);
    }

    let style = document.createElement('style');
    //style.appendChild(document.createTextNode(`
    //    @font-face {
    //        font-family: ${this.fontFamily};
    //        src: url('${this.fontFamilyUrl}`);
    //    }`
    //));

    style.appendChild(
        document.createTextNode(`body { font-family: '${this.fontFamily}' }`)
    );

    document.head.appendChild(style);    
}

You can have a lookup table for values of fontFamily and fontFamily url corresponding to the available locales within the component and probably computed properties for fontFamily & fontFamily url based on selected locale

data(){
    return {
        //fonts: {
        //    en: 'Nunito', url: '/fonts/Nunito/Nunito-Regular.ttf'},
        //    id: { fontFamily: 'Righteous', url: '/fonts/Righteous/Righteous-Regular.tt'},
        //    fa: { fontFamily: 'Dirooz', url: '/fonts/dirooz/Dirooz.ttf'}
       // },

        fonts: {
            en: 'Nunito',
            id: 'Righteous',
            fa: 'Dirooz'
        },
        initialStyleTagsCount: this.getStyleTagsCount()
        // other data properties
    }
},

computed:{

    //fontFamily() {
    //    return this.fonts[this.locale]['fontFamily'];
    //},
    //fontFamilyUrl() {
    //    return this.fonts[this.locale]['url'];
    //},
    
    fontFamily() {
        return this.fonts[this.locale];
    }
},

methods:{
    getStyleTagsCount() {
        return document.querySelectorAll('style').length;
    }
}
