Vue 3 vue-i18n. How to use $t(t) outside the application (.vue file)? Synthesis API

Question

I want to format my datetime outside the component.

function transformDatetime(config, value) {
    if (value) {
        return $d(new Date(value), config);
    }
    return $t('-');
}

I'm trying to get $t from the application instance. But it only works in component context, just like useI18n.

import { getCurrentInstance } from 'vue'

export default function useGlobal() {
    const instance = getCurrentInstance()
    if (!instance) return
    return instance.appContext.config.globalProperties
}

I found the solution. Just import your i18n into a file outside your application and use i18n.global.t

import { createI18n } from "vue-i18n"

export const i18n = createI18n({
    legacy: false,
    locale: 'ja',
    fallbackLocale: 'en',
    messages,
})

import { i18n } from '@/i18n'

const { t: $t, d: $d, n: $n } = i18n.global

const expample = $t('some-text')
