Translating

You can implement translation in your Vue application in the following ways.

• Using the global $t function
• Using the useTranslate composable
• Using the T component

Global $t function

The VueTolgee plugin provides a $t function that allows you to translate strings in your Vue application. If the VueTolgee plugin is registered, the $t function is available globally in your application.

<template>
  <div>{{ $t('this_is_a_key') }}</div>
</template>

useTranslate composable

The Tolgee integration library provides the useTranslate composable, which comes with a translation function (t function). Using this t function, you can render the actual translation.

<template>
  <div :title="t('key')">...</div>
</template>

<script setup>
  import { useTranslate } from '@tolgee/vue';

  const { t } = useTranslate();
</script>

t function

This function allows you to render the actual translation.

Simple usage

t('app_title')

The t function looks into your translations finds an appropriate key and renders the translation for currently selected language

If you use Typescript read about typed keys

Default value

You can pass the default value as second parameter, which will be rendered if the key doesn't exist yet.

t('non_existant_key', 'Default value')

Parameter interpolation

You can supply a variable parameters which will then be rendered in your translations.

t('user_points', 'User has {count} points', { count: 10 })

// -> User has 10 points

There are more options you can do with the variable parameters, but it depends on selected formatter plugin.

To get the full t function specification check it's API

Using namespaces

The useTranslate composable can be also used for loading additional namespaces.

const { t, isLoading } = useTranslate('common');

This example will load common namespace which can be then used with t function.

The T component

An alternative way is to use the T component. It has a very similar API to the t function mentioned above.

<template>
  <T
    keyName="translation_key"
    defaultValue="User has {count} points"
    :params="{ count: 10 }"
 />
</template>

<script setup>
  import { T } from '@tolgee/vue';
</script>
