# Vue: Translating strings

Description: How to translate Vue labels, attributes, and shared strings with useGT and useMessages.

Use [`useGT()`](/docs/vue/reference/composables/use-gt) for strings that cannot be expressed as template content, such as placeholders, accessible labels, and values passed to another component. Use [`msg()`](/docs/vue/reference/functions/msg) with [`useMessages()`](/docs/vue/reference/composables/use-messages) when a static message is declared in one module and rendered in another.

## Translate with `useGT` [#use-gt]

Call [`useGT()`](/docs/vue/reference/composables/use-gt) during component setup, then call its returned function from the template:

```vue
<script setup lang="ts">
import { useGT } from 'gt-vue';

const gt = useGT();
</script>

<template>
  <input
    type="search"
    :placeholder="gt('Search products')"
    :aria-label="gt('Search')"
  />
</template>
```

Use a string literal so the CLI can extract it. Missing catalogue entries return the source string.

The only supported option is a static `$context`:

```vue
<button>{{ gt('Archive', { $context: 'verb on a project action' }) }}</button>
```

Braces are literal text. [`useGT()`](/docs/vue/reference/composables/use-gt) does not process ICU syntax, interpolate variables, or accept React string options such as `$id`, `$maxChars`, and `$format`.

## Keep translated results reactive [#reactivity]

The function returned by [`useGT()`](/docs/vue/reference/composables/use-gt) reads the active catalogue when called. Call it from a template, computed value, or reactive effect when the result should update after a locale or catalogue change:

```vue
<script setup lang="ts">
import { computed } from 'vue';
import { useGT } from 'gt-vue';

const gt = useGT();
const pageTitle = computed(() => gt('Account settings'));
</script>

<template>
  <h1>{{ pageTitle }}</h1>
</template>
```

`const pageTitle = gt('Account settings')` translates once during setup and stores a snapshot. It does not run again when a [`createGT()`](/docs/vue/reference/functions/create-gt) plugin switches locale.

## Register shared messages [#messages]

Use [`msg()`](/docs/vue/reference/functions/msg) to register static strings in a shared module. It marks content for extraction; it does not perform a translation lookup.

```ts title="src/messages.ts"
import { msg } from 'gt-vue';

export const statusMessages = {
  active: msg('Active', { $context: 'account status' }),
  paused: msg('Paused', { $context: 'account status' }),
};
```

Resolve the selected message with [`useMessages()`](/docs/vue/reference/composables/use-messages) where it is rendered:

```vue title="src/components/StatusBadge.vue"
<script setup lang="ts">
import { computed } from 'vue';
import { useMessages } from 'gt-vue';
import { statusMessages } from '../messages';

const props = defineProps<{ status: keyof typeof statusMessages }>();
const m = useMessages();
const label = computed(() => m(statusMessages[props.status]));
</script>

<template>
  <span>{{ label }}</span>
</template>
```

Without options, [`msg()`](/docs/vue/reference/functions/msg) returns the original string unchanged. With `$context`, it adds opaque lookup metadata that [`useMessages()`](/docs/vue/reference/composables/use-messages) reads. Do not parse or make assumptions about that encoded representation.

## Translate content with runtime values [#variables]

Plain string lookups do not interpolate runtime data. Put the complete phrase in [`<T>`](/docs/vue/reference/components/t) and mark the changing value with [`<Var>`](/docs/vue/reference/components/var):

```vue
<T>Welcome back, <Var>{{ accountName }}</Var>!</T>
```

Use [`<Num>`](/docs/vue/reference/components/num), [`<Currency>`](/docs/vue/reference/components/currency) and [`<DateTime>`](/docs/vue/reference/components/datetime) when the value also needs locale-aware formatting.

Browser-only SPAs that need a static lookup while modules are evaluated can use [`t()`](/docs/vue/reference/functions/t) after awaiting [`initializeGTSPA()`](/docs/vue/reference/functions/initialize-gt-spa). Follow [Developing with SPA translations](/docs/vue/guides/developing-spa-translations) to preserve the required import order.
