import { locale } from 'svelte-i18n'
The locale
store defines what is the current locale. When its value is changed, before updating the actual stored value, svelte-i18n
sees if there's any message loaders registered for the new locale:
- If yes, changing the
locale
is an async operation. - If no, the locale's dictionary is fully loaded and changing the locale is a sync operation.
The <html lang>
attribute is automatically updated to the current locale.
To change the locale inside a component is as simple as assinging it a new value.
<script>
import { locale, locales } from 'svelte-i18n'
</script>
<select bind:value={$locale}>
{#each $locales as locale}
<option value={locale}>{locale}</option>
{/each}
</select>
import { locale } from 'svelte-i18n'
// Set the current locale to en-US
locale.set('en-US')
// This is a store, so we can subscribe to its changes
locale.subscribe(() => console.log('locale change'))
While changing the $locale
, the $isLoading
store can be used to detect if the app is currently fetching any enqueued message definitions.
<script>
import { isLoading } from 'svelte-i18n'
</script>
{#if $isLoading}
Please wait...
{:else}
<Nav />
<Main />
{/if}
$isLoading
will only betrue
if fetching takes more than 200ms.
