# Come testare le traduzioni in locale

> [!NOTE] Questo processo non è richiesto, ma documentato nel caso tu voglia vedere la preview delle tue traduzioni.

Se vuoi testare le tue traduzioni in una istanza locale della piattaforma `/learn` di freeCodeCamp, assicurati prima di aver [preparato il codebase](how-to-setup-freecodecamp-locally.md).

## Attivare una lingua

Ci sono alcuni step da fare per avere una build del codebase nella lingua di tua scelta.

First, visit the `config/i18n/all-langs.ts` file to add the language to the available languages list and configure the values. Ci sono quattro oggetti qui.

- `availableLangs`: Aggiungi il nome testuale della lingua agli array `client` e `curriculum`. Questo è il valore che sarà usato nel file `.env` più tardi.
- `auditedCerts`: Add the text name of the language as the _key_, and add an array of `SuperBlocks.{cert}` variables as the _value_. This tells the client which certifications are fully translated.
- `i18nextCodes`: These are the ISO language codes for each language. You will need to add the appropriate ISO code for the language you are enabling. These do need to be unique for each language.
- `langDisplayNames`: These are the display names for the language selector in the navigation menu.
- `langCodes`: These are the language codes used for formatting dates and numbers. These should be Unicode CLDR codes instead of ISO codes.

Per esempio, se vuoi attivare la lingua Dothraki, il tuo oggetto `all-langs.js` dovrebbe essere come segue:

```js
const availableLangs = {
  client: ['english', 'espanol', 'chinese', 'chinese-traditional', 'dothraki'],
  curriculum: [
    'english',
    'espanol',
    'chinese',
    'chinese-traditional',
    'dothraki'
  ]
};

export const auditedCerts = {
  espanol: [
    SuperBlocks.RespWebDesign,
    SuperBlocks.JsAlgoDataStruct,
    SuperBlocks.FrontEndDevLibs,
    SuperBlocks.DataVis,
    SuperBlocks.BackEndDevApis
  ],
  chinese: [
    SuperBlocks.RespWebDesign,
    SuperBlocks.JsAlgoDataStruct,
    SuperBlocks.FrontEndDevLibs,
    SuperBlocks.DataVis,
    SuperBlocks.BackEndDevApis,
    SuperBlocks.QualityAssurance,
    SuperBlocks.SciCompPy,
    SuperBlocks.DataAnalysisPy,
    SuperBlocks.InfoSec,
    SuperBlocks.MachineLearningPy
  ],
  'chinese-traditional': [
    SuperBlocks.RespWebDesign,
    SuperBlocks.JsAlgoDataStruct,
    SuperBlocks.FrontEndDevLibs,
    SuperBlocks.DataVis,
    SuperBlocks.BackEndDevApis,
    SuperBlocks.QualityAssurance,
    SuperBlocks.SciCompPy,
    SuperBlocks.DataAnalysisPy,
    SuperBlocks.InfoSec,
    SuperBlocks.MachineLearningPy
  ],
  dothraki: [
    SuperBlocks.RespWebDesign,
    SuperBlocks.JsAlgoDataStruct,
    SuperBlocks.FrontEndDevLibs
  ]
};

const i18nextCodes = {
  english: 'en',
  espanol: 'es',
  chinese: 'zh',
  'chinese-traditional': 'zh-Hant',
  dothraki: 'mis'
};

const langDisplayNames = {
  english: 'English',
  espanol: 'Español',
  chinese: '中文（简体字）',
  'chinese-traditional': '中文（繁體字）',
  dothraki: 'Dothraki'
};

const langCodes = {
  english: 'en-US',
  espanol: 'es-419',
  chinese: 'zh',
  'chinese-traditional': 'zh-Hant',
  dothraki: 'mis'
};
```

Next, open the `client/src/utils/algolia-locale-setup.ts` file. Questi dati sono usati dalla barra di ricerca che carica gli articoli in `/news`. Anche se è poco probabile che tu stia testando questa funzione, se questi dati mancano per la tua lingua possono esserci degli errori nel costruire il codebase localmente.

Aggiungi un oggetto per la tua lingua all'oggetto `algoliaIndices`. Dovresti usare i valori dell'oggetto `english` per testare in locale, sostituiendo la chiave `english` con il valore della tua lingua in `availableLangs`.

> [!NOTE] If we have already deployed an instance of news in your target language, you can update the values to reflect the live instance. Otherwise, use the English values.

Se volessi aggiungere Dothraki:

```js
const algoliaIndices = {
  english: {
    name: 'news',
    searchPage: 'https://www.freecodecamp.org/news/search/'
  },
  espanol: {
    name: 'news-es',
    searchPage: 'https://www.freecodecamp.org/espanol/news/search/'
  },
  chinese: {
    name: 'news-zh',
    searchPage: 'https://chinese.freecodecamp.org/news/search/'
  },
  'chinese-traditional': {
    name: 'news-zh',
    searchPage: 'https://chinese.freecodecamp.org/news/search'
  },
  dothraki: {
    name: 'news',
    searchPage: 'https://www.freecodecamp.org/news/search/'
  }
};
```

Finally, in your `.env` file, set `CLIENT_LOCALE` and `CURRICULUM_LOCALE` to your new language (use the `availableLangs` value.)

```txt
CLIENT_LOCALE="dothraki"
CURRICULUM_LOCALE="dothraki"
```

## Attivare video localizzati

For the video challenges, you need to change a few things. First add the new locale to the GraphQL query in the `client/src/templates/Challenges/video/Show.tsx` file. For example, adding Dothraki to the query:

```tsx
  query VideoChallenge($slug: String!) {
    challengeNode(fields: { slug: { eq: $slug } }) {
      videoId
      videoLocaleIds {
        espanol
        italian
        portuguese
        dothraki
      }
      ...
```

Then add an id for the new language to any video challenge in an audited block. For example, if `auditedCerts` in `all-langs.ts` includes `scientific-computing-with-python` for `dothraki`, then you must add a `dothraki` entry in `videoLocaleIds`. The frontmatter should then look like this:

```yml
videoLocaleIds:
  espanol: 3muQV-Im3Z0
  italian: hiRTRAqNlpE
  portuguese: AelGAcoMXbI
  dothraki: new-id-here
dashedName: introduction-why-program
---
```

Update the `VideoLocaleIds` interface in `client/src/redux/prop-types` to include the new language.

```ts
export interface VideoLocaleIds {
  espanol?: string;
  italian?: string;
  portuguese?: string;
  dothraki?: string;
}
```

And finally update the challenge schema in `curriculum/schema/challengeSchema.js`.

```js
videoLocaleIds: Joi.when('challengeType', {
  is: challengeTypes.video,
  then: Joi.object().keys({
    espanol: Joi.string(),
    italian: Joi.string(),
    portuguese: Joi.string(),
    dothraki: Joi.string()
  })
}),
```

## Caricare le traduzioni

Because the language has not been approved for production, our scripts are not automatically downloading the translations yet. Only staff have the access to directly download the translations - you are welcome to reach out to us in our [contributors chat room](https://chat.freecodecamp.org/channel/contributors), or you can translate the English markdown files locally for testing purposes.

Once you have the files, you will need to place them in the correct directory. For the curriculum challenges, you should place the certification folders (i.e. `01-responsive-web-design`) within the `curriculum/challenges/{lang}` directory. For our Dothraki translations, this would be `curriculum/challenges/dothraki`. The client translation `.json` files will go in the `client/i18n/locales/{lang}` directory.

Once these are in place, you should be able to run `npm run develop` to view your translated version of freeCodeCamp.

> [!ATTENTION] While you may perform translations locally for the purpose of testing, we remind everyone that translations should _not_ be submitted through GitHub and should only be done through Crowdin. Be sure to reset your local codebase after you are done testing.
