Vue router - cannot lazy load component - Unexpected Token

I am trying to lazy load the Login component for my login route. When building webpack I get:

SyntaxError: Unexpected Token

The Login.vue component works fine if I import and assign it the same way I do the Home route.

I'm baffled because I believe this code should work based on this blog.

The line that fails below is:

component: () => import('../components/Login.vue'),

router.js

import Vue from 'vue'
import VueRouter from 'vue-router'
import Home from '../components/Home.vue'


Vue.use(VueRouter)


export default new VueRouter({
    mode: 'history',

    routes: [
        {
            path: '/',
            name: 'home',
            component: Home,
            meta: {
                permission: "anonymous",
            },
        },

        {
            path: '/login/',
            name: 'login',
            component: () => import('../components/Login.vue'),
            meta: {
                permission: "anonymous",
            },
        },
    ],
})

Your webpack is not configured the spec! Só there are two ways to solve your problem!

The first one is to change all occurence of import('path/to/component.vue') to System.import('path/to/component.vue')

And the second is using BABEL with the folowing configuration

.babelrc

{
  "presets": [
    ["es2015", { "modules": false }],
    "stage-2"
  ],
  "plugins": [
    "transform-export-extensions"
  ]
}

Resources

ES6 Modules

Dynamic Import

Stage-2 Babel Preset
