TS loader does not work with vue files

[iSynth]

My index.vue file:

<template>
    <section>
        INDEX
    </section>
</template>

<script lang="ts">

    import { Component, Vue } from 'nuxt-property-decorator'

    @Component({})
    export default class Index extends Vue {

    }
</script>

My tsconfig.json file:

.....

"experimentalDecorators": true,
 "emitDecoratorMetadata" : true
.....

I got this error message

Module parse failed: Unexpected character '@' (11:0)
You may need an appropriate loader to handle this file type.
| import { Component, Vue } from 'nuxt-property-decorator'

@component({}

| export default class Index extends Vue {

I'm sorry, I've updated my repository, if you're able to recheck if it works now, I'd be happy. I've also added some documentation on where I've gotten my input from, who laid the work for getting to this.
