Vue code splitting in Laravel

I'm struggling to figure out how this code splitting works. As of now the JS file has become way too big and code splitting is a must. I saw Evan You writing this in a presentation:

const Component = () => import('./Component.vut')

But Webpack won't let me compile that.

I'm importing my components as

Vue.component('Component', require('./Component.vue'))

Hope some of you can help me out here :-)
