-
-const i18n = new VueI18n({

-  messages: {
-    en: {
-      hello: 'hello'
-    },
-    ja: {
-      hello: 'こんにちは'
-    }
-  }
-})
-const renderer = createRenderer({ directives: { t } })
-
-const app = new Vue({
-  i18n,
-  render (h) {
-    // <p v-t="'hello'"></p>
-    return h('p', {
-      directives: [{
-        name: 't', rawName: 'v-t',
-        value: ('hello'), expression: "'hello'"
-      }]
-    })
-  }
-})
-
-renderer.renderToString(app, (err, html) => {

-import { compile } from 'vue-template-compiler'
-import { module } from '@intlify/vue-i18n-extensions'
-
-Vue.use(VueI18n)
-
-const i18n = new VueI18n({
-  locale: 'en',
-  messages: {
-    en: {
-      hello: 'hello'
-    },
-    ja: {
-      hello: 'こんにちは'
-    }
-  },
-  missing: (locale, key) => {
-    console.log(`translation missing: locale=${locale}, key=${key}`)
-  }
-})
-const i18nModule = module(i18n)
-
-const { ast, render } = compile(`<p v-t="'hello'"></p>`, { modules: [i18nModule] })
-console.log(ast.i18n) // output -> 'hello'
-console.log(render) // output -> `with(this){return _c('p',{domProps:{"textContent":_s("hello")}})}`
-```
-
-The following configration example of `vue-loader`:
-
-```javascript
-const Vue = require('vue')
-const VueI18n = require('vue-i18n')
-const i18nExtensions = require('@intlify/vue-i18n-extensions')
-const messages = require('./locales.json')
-
-Vue.use(VueI18n)
-
-const i18n = new VueI18n({
-  locale: 'ja',
-  messages: messages
-})
-
-module.exports = {
-  module: {
-    rules: [{
-      test: /\.vue$/,
-      loader: 'vue',
-      options: {
-        compilerModules: [i18nExtensions.module(i18n)],
