<p align="center">vue-i18n loader for custom blocks</p>

<br/>

## :cd: Installation

    $ npm i --save-dev @intlify/vue-i18n-loader

## :rocket: Usage

the below example that`App.vue` have `i18n` custom block:

### Basic

```vue
<template>
  <p>{{ $t('hello') }}</p>
</template>

<script>
export default {
  name: 'app',
  // ...
}
</script>

<i18n>
{
  "en": {
    "hello": "hello world!"
  },
  "ja": {
    "hello": "こんにちは、世界!"
  }
}
</i18n>
```

The locale messages defined at  `i18n` custom blocks are **json format default**.

### Source importing

you also can:

```vue
<i18n src="./myLang.json"></i18n>
```

```json5
// ./myLnag.json
{
  "en": {
    "hello": "hello world!"
  },
  "ja": {
    "hello": "こんにちは、世界!"
  }
}
```

### Locale definition

You can define locale messages for each locale with `locale` attr in single-file components:

```vue
<i18n locale="en">
{
  "hello": "hello world!"
}
</i18n>

<i18n locale="ja">
{
  "hello": "こんにちは、世界!"
}
</i18n>
```

The above defines two locales, which are merged at target single-file components.


### Locale Messages formatting

Besides json format, You can be used by specifying the following format in the `lang` attribute:

- yaml
- json5

example yaml foramt:

```vue
<i18n locale="en" lang="yaml">
  hello: "hello world!"
</i18n>

<i18n locale="ja" lang="yml">
  hello: "こんにちは、世界！"
</i18n>
```

example json5 format:

```vue
<i18n lang="json5">
{
  "en": {
    // comments
    "hello": "hello world!"
  }
}
</i18n>
```

### JavaScript

```javascript
import Vue from 'vue'
import VueI18n from 'vue-i18n'
import App from './App.vue'

Vue.use(VueI18n)

const i18n = new VueI18n({
  locale: 'en',
  messages: {
    en: {
      // ...
    },
    ja: {
      // ...
    }
  }
})
new Vue({
  i18n,
  render: h => h(App)
}).$mount('#app')
```

### Webpack Config

module.exports = {
  chainWebpack: config => {
    config.module
      .rule('i18n')
      .resourceQuery(/blockType=i18n/)
      .type('javascript/auto')
      .use('i18n')
      .loader('@intlify/vue-i18n-loader')
  }
}
```

      },
    ]
