svelte-intl-precompile

• Purpose: A Svelte.js i18n library that compiles translations during build time rather than parsing them in the browser, resulting in smaller bundle sizes and faster performance.
• Key Features:
  • Compiles ICU message syntax into optimized JavaScript functions during build.
  • Uses native Intl API for runtime operations, reducing bundle size.
  • Supports dynamic translations, pluralization, number/date formatting, and more.
  • Significantly smaller (~2kb) and faster (up to 4x) compared to runtime-parsing alternatives like svelte-i18n.
• Target Audience: Svelte.js developers needing efficient internationalization with minimal runtime overhead.
• Svelte Support: Designed specifically for Svelte, with an API similar to svelte-i18n for ease of adoption.
• Documentation: Detailed docs available at svelte-intl-precompile.com fa-solid fa-up-right-from-square.
• Workflow:
  • Translations are defined in JSON/JS files (e.g., en.json, es.json).
  • A Vite/SvelteKit plugin precompiles translations during build.
  • Runtime initialization mirrors svelte-i18n, supporting lazy loading and SSR.
• SSR Note: Includes guidance for locale detection in server-rendered apps (e.g., using accept-language headers).

Example Use Case:

<script>
  import { t } from 'svelte-intl-precompile';
</script>
<footer>{$t("footer.cta")}</footer>
