Question 1

svelte-i18n vs svelte-intl – which is better for my project?

Accepted Answer

svelte-i18n is more lightweight and tightly integrated with Svelte's reactivity using stores, while svelte-intl might offer broader i18n features. Choose based on whether you prioritize simplicity and native Svelte feel over extended functionality.

Question 2

How to change the locale dynamically in svelte-i18n?

Accepted Answer

Import the locale store and update its value to a new locale code. The UI will reactively refresh, but ensure your loaded dictionary includes translations for that locale to avoid missing keys.

Question 3

Does svelte-i18n support TypeScript?

Accepted Answer

Yes, it includes TypeScript definitions, enabling type-safe usage of translation keys and parameters in Svelte components for better development experience.

Question 4

How to handle missing translations or fallback locales?

Accepted Answer

Use default values in the $_ function, like $_('key', { default: 'Fallback text' }). For locale fallbacks, configure multiple dictionaries or set up fallback chains in the initialization settings.

Question 5

What's the best practice for loading translation files in Svelte Kit?

Accepted Answer

Follow the dedicated Svelte Kit documentation to asynchronously load JSON dictionaries in a layout or component, initializing the locale based on user preferences or route parameters.

Question 6

Can I use svelte-i18n with server-side rendering in Svelte Kit?

Accepted Answer

Yes, it's compatible with SSR in Svelte Kit. Ensure proper hydration by setting the initial locale on the server and synchronizing it on the client to prevent UI mismatches.
