🛠️ Example Usages

Basic Usage

<i18n-t keypath="feedback.text" />

This renders the translation for feedback.text within a <span> tag.

Using Slots for Dynamic Content

The <i18n-t> component supports the use of slots to dynamically insert Vue components or other content into specific parts of the translation.

<i18n-t keypath="feedback.text">
  <template #link>
    <nuxt-link :to="{ name: 'index' }">
      <i18n-t keypath="feedback.link" />
    </nuxt-link>
  </template>
</i18n-t>

In this example, the {link} placeholder in the feedback.text translation string is replaced by the <nuxt-link> component, which itself contains another translation component.

Pluralization

<i18n-t keypath="items.count" :plural="itemCount" />

This automatically applies pluralization rules based on the itemCount value.

🚀 Additional Features

Default Slot

If no specific slot is provided, the translation can be customized via the default slot, which provides the entire translated string:

<i18n-t keypath="welcome.message">
  <template #default="{ translation }">
    {{ translation.replace('Nuxt', 'Vue') }}
  </template>
</i18n-t>

Conditional Rendering

Render nothing if the translation string is empty by using the hideIfEmpty prop.

<i18n-t keypath="optionalMessage" :hideIfEmpty="true"></i18n-t>

Custom Pluralization Rule

Use a custom function to handle pluralization.

<i18n-t
  keypath="items"
  :plural="itemCount"
  :customPluralRule="(key, value, count, locale) => {
    return count === 1 ? 'One item' : `${count} items`;
  }}"
></i18n-t>

Advanced Example with Slots

Utilize slots to customize how the translation content is rendered.

<i18n-t keypath="welcomeMessage">
  <template #default="{ translation }">
    <strong>{{ translation }}</strong>
  </template>
</i18n-t>
