[Vuejs]-Theme Choosing on the basis of a certain API value

i did this simple task and worked like charm:

data(){
     return{
       api_value:0
     }
   },
   beforeCreate(){
     axios.get('my-api-link)
         .then(response=>{
          this.api_value = response.data.api_value
      })

   },

     computed:{
         inject_theme(){
           if(this.api_value ==1)
             return '/theme/dark.css'
           else if (this.api_value ==2)
              return '/theme/dark.1.css'
           else if (this.api_value ==3)
              return '/theme/dark.2.css'
         }
       },

   head () {
    return {
      title: this.title,
      meta: [
        { hid: 'description', name: this.inject_theme, content: 'My custom description' }
      ],
      link:[
        {rel:'stylesheet',href:this.inject_theme}
      ] 
    }
  }
