Lingui is a lightweight (2 kb core) internationalization (i18n) framework for JavaScript and TypeScript projects, built on ICU MessageFormat. It provides framework-agnostic core functionality, React/React Native/SolidJS bindings, and tooling (CLI, Vite plugin, ESLint plugin) to extract, compile, and manage translation catalogs in PO, JSON, or CSV formats.

Use cases

• internationalize a React web application
• translate UI strings into multiple languages
• handle plurals and gender in translations
• extract translatable messages from source code into PO files
• add i18n to a React Native mobile app
• localize a Node.js backend or CLI
• manage translation catalogs with translators using standard tools

When to choose

• you want a lightweight i18n library with a tiny bundle footprint
• your project uses React, React Native, SolidJS, Vue, Astro, or Svelte
• you need ICU MessageFormat support for plurals, genders, and selects
• you want a full extract-and-compile workflow with CLI tooling
• your translators work with standard PO files or translation tools

When to avoid

• you need i18n for a non-JavaScript stack
• you prefer a framework with built-in opinionated routing-based localization like Next.js i18n routing
• you need heavy machine-translation or TMS features out of the box
• your project is a single-language app with no localization plans
