Vuejs make .vue global in app.js Laravel 5

I have a vue file validations.vue of validations.js.

validations.vue

<script>
    import VueFormGenerator from "vue-form-generator";
    Vue.use(VueFormGenerator);

    VueFormGenerator.validators.postcode = function(value, field, model) {
        let re = /^[1-9][0-9]{3} ?[A-Za-z]{2}$/;

        if (!re.test(value)) {
            return ["Ongeldige postcode"];
        } else {
            return []
        }
    };
</script>

Postcode check:

import VueFormGenerator from "vue-form-generator";
Vue.use(VueFormGenerator);

export default {
    data() {
        return {
            model: {
                postcode: "",
                huisnummer: ''
            },
            schema: {
                fields: [{
                    type: "input",
                    inputType: "text",
                    model: "postcode",
                    placeholder: "Postcode",
                    label: "Postcode",
                    validator: VueFormGenerator.validators.postcode, <---------------
                },{

How can i make it accessible in all vue files?
