## What it is
svelte-i18n is an internationalization library for Svelte apps that uses Svelte stores to track the current locale, message dictionaries, and message formatting. It provides reactive helpers like the `_` format function for localizing text directly in Svelte components.

## Use cases
- translate a svelte app into multiple languages
- switch locales reactively in a svelte application
- load message dictionaries from  files
- format localized messages with defaults in svelte components
- set up i18n in a sveltekit project

## When to choose
- you are building a Svelte or SvelteKit app and need lightweight, reactive i18n
- you want store-based locale and dictionary management that fits Svelte idioms
- you need simple message formatting with nested JSON dictionaries

## When to avoid
- you need a framework-agnostic i18n solution for non-Svelte projects
- you need instance-based (non-singleton) i18n configuration or heavy multi-instance support
- your project requires ICU message format features beyond what the library supports

## Facets
- artifact type: library
- maturity: maintenance
- function: internationalization, templating, state-management
- domain: web-development, frontend
- platform: browser
