Main Functions and use cases are:

• Receiving localized input from user

Static Properties

createLocalizedString(languages, existingTranslations)

This function creates a localized string. It merges the languages and the language keys of existing translations to form a localized string holding all languages. The existingTranslations argument is optional. If it is not passed, an empty localized field will be created.

const languages = ['en', 'de'];
LocalizedTextInput.createLocalizedString(languages);
// -> { en: '', de: '' }

In case existingTranslations is passed, it will merge an empty localized field with the exisiting translations. Usually this is used to ensure that a localized string contains at least the project's languages.

const languages = ['en', 'de'];
const existingTranslations = { en: 'Tree', ar: 'شجرة' };
LocalizedTextInput.createLocalizedString(languages, existingTranslations);
// -> { en: 'Tree', de: '', ar: 'شجرة' }

isEmpty(localizedField)

Returns true when all values in a localized field are empty.

LocalizedTextInput.isEmpty({});
// -> true

LocalizedTextInput.isEmpty({ en: '', de: '  ' });
// -> true

LocalizedTextInput.isEmpty({ en: 'Tree', de: '' });
// -> false

omitEmptyTranslations(localizedField)

Omits translations with empty values.

LocalizedTextInput.omitEmptyTranslations({ en: '', de: '  ' });
// -> {}

LocalizedTextInput.omitEmptyTranslations({ en: 'Tree', de: '' });
// -> { en: 'Tree' }

isTouched(touched)

Expects to be called with an object or undefined. Returns true when at least one value is truthy.

RequiredValueErrorMessage

This field exports a default error message which can be used when the field is required, but the user provided no value. You can use it as

<LocalizedTextInput hasError={isMissing} />;
{
  isMissing && <LocalizedTextInput.RequiredValueErrorMessage />;
}

getId(idPrefix, language)

Returns the id of the input field of a specific language. This is useful in case you want to create a label for the input field. You can use it as

LocalizedTextInput.getId('name', 'en');
// -> "name.en"

Or as a more complete example:

<label htmlFor={LocalizedTextInput.getId('name', 'en')}>Name</label>
<LocalizedTextInput
  id="name"
  selectedLanguage="en"
  // ...
/>

getName(idPrefix, language)

Returns the name of the input field of a specific language. . You can use it as

LocalizedTextInput.getName('slug', 'en');
// -> "slug.en"
