[2336] Trying to add a mixin to main Vue instance

Hi guys,

I'm trying to add some global data (and methods) to main Vue instance. I don't want to use Vuex so I end up with creating a plugin for nuxt:

import Vue from 'vue'

Vue.mixin({
    data: {
        my_global_config: 'This'
    },
    created: function () {
        console.log('mixin hook called')
    }
    methods: {}
})

Created method works correctly but I don't have access to data using this.$root.my_global_config Any idea?
