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