# Languages

### 1. Backend Server

Add new locale id into `locales` in `core/config/Locale.js` file.

```
const locales = Object.freeze({
    en: "en",
    id: "id",
    es: "es",
    hi: "hi",
    ru: "ru",
    pt: "pt",
    zh: "zh",
    ja: "ja"
    // add new locale id
})
```

Next step is add default error messages into `langValidation` in `core/locale/LangValidation.js` file.

```
const langValidation = Object.freeze({
    required: {
        "en": "The _attribute_ is required",
        "id": "_attribute_ wajib di isi",
        "es": "El campo _attribute_ es obligatorio",
        "hi": "_attribute_ आवश्यक है",
        "ru": "Поле _attribute_ является обязательным",
        "pt": "O campo _attribute_ é obrigatório",
        "zh": "_attribute_ 必填",
        "ja": "_attribute_ は必須です"
        // add new translation with new locale id
    },
    email: {
        "en": "The _attribute_ must be in E-mail format",
        ............
```

Then new translation into dictionary in `core/locale/Dictionary.js` file. 

```
const Dictionary = Object.freeze({
  "success": {
    "en": "success",
    "id": "sukses",
    "es": "éxito",
    "hi": "सफलता",
    "ru": "успех",
    "pt": "sucesso",
    "zh": "成功",
    "ja": "成功"
    // add new translation with new locale id
  },
  "failed": {
    "en": "failed",
    .........
```

### 2. Bliss App & Admin App

First add locale id into enum `LocaleId` in `lib/config/LocaleConfig.dart` file.

```
enum LocaleId { en, id, es, hi, ru, pt, zh, ja } // add new locale id into this enum
```

Then add language into static function `locales()`

```
class LocaleConfig {
  /**
   * list of locales
   */
  static List<Language> locales() {
    return [
      Language(id: LocaleId.en.name, name: "English"),
      Language(id: LocaleId.id.name, name: "Bahasa Indonesia"),
      Language(id: LocaleId.es.name, name: "Español (Spanish)"),
      Language(id: LocaleId.hi.name, name: "हिंदी (Hindi)"),
      Language(id: LocaleId.ru.name, name: "Русский (Rusia)"),
      Language(id: LocaleId.pt.name, name: "Português (Portugis)"),
      Language(id: LocaleId.zh.name, name: "中文 (Mandarin)"),
      Language(id: LocaleId.ja.name, name: "日本語 (Japanese)"),
      // add new Language() model here with new id from enum that you add before
    ];
  }
```

The last step is, add new translation language into `assets/lang/lang.json` file.&#x20;

```
{
    "ok":{
        "en":"ok",
        "id":"oke",
        "es": "vale",
        "hi": "ठीक",
        "ru": "ок",
        "pt": "ok",
        "zh": "好",
        "ja": "はい"
        // add new translation with new locale id
    },
    "yes":{
        "en":"yes",
        ..........
```

Note: both admin the bliss app using same json on the app, means if you add new language in admin app, you must copy that `lang.json` into bliss app too.
