[Vuejs]-Kalendar-vue with webpack: "You may need an appropriate loader to handle this file type."Hi

Remove the .css from this line

extensions: [".js", ".vue", ".css"],

Your resolve for vue should look like:

resolve: {
    alias: {
        'vue$': 'vue/dist/vue.esm.js'
    },
    extensions: ['*', '.js', '.vue', '.json']
},

Theres no reason to place CSS there as webpack will compile it on the side
