Lingui internationalization setup requires configuring I18nProvider, macros, and runtime loading for your React app. You must correctly wrap your UI components with the provider and import macros to enable message extraction and locale switching.

Extracting and compiling Lingui message catalogs involves running the CLI to pull translatable strings from macros into catalog files, then compiling them for runtime. This workflow ensures translations are correctly loaded and activated across your application environments.

Lingui macro extraction breaks when macros are used at the module level rather than within component render scopes. Avoid missing providers, unstable memoization, and incorrect import paths to ensure proper translation message extraction.

Pluralization and locale-aware formatting in Lingui are handled using specific macros within your message definitions. You can correctly pluralize counts and format locale-aware dates and numbers directly in your React UI components.

Lingui supports JavaScript localization alongside React implementations. You can apply the same message catalogs, macros, and locale switching workflows to web or native applications to localize translated buttons, forms, and alerts.
