# i18n
## Usages
- Update missing translations into the base resources, a.k.a the `src/resources/en.json`
- Replace literal text with translation keys
```tsx
import { useAFFiNEI18N } from '@affine/i18n/hooks';
// src/resources/en.json
// {
// 'Text': 'some text',
// 'Switch to language': 'Switch to {{language}}', // <- you can interpolation by curly brackets
// };
const App = () => {
const t = useAFFiNEI18N();
const changeLanguage = (language: string) => {
i18n.changeLanguage(language);
};
return (
<div>
<div>{t('Text')}</div>
<button onClick={() => changeLanguage('en')}>{t('Switch to language', { language: 'en' })}</button>
<button onClick={() => changeLanguage('zh-Hans')}>{t('Switch to language', { language: 'zh-Hans' })}</button>
</div>
);
};
```
## How the i18n workflow works?
- When the `src/resources/en.json`(base language) updated and merged to the develop branch, will trigger the `languages-sync` action.
- The `languages-sync` action will check the base language and add missing translations to the Tolgee platform.
- This way, partners from the community can update the translations.
## How to sync translations manually
- Set token as environment variable
```shell
export TOLGEE_API_KEY=tgpak_XXXXXXX
```
- Run the `sync-languages:check` to check all languages
- Run the `sync-languages` script to add new keys to the Tolgee platform
- Run the `download-resources` script to download the latest full-translation translation resources from the Tolgee platform
