What i18n package to use? Next.js libraries breakdown:
I was investigating today which internationalization package to use. The Next.js docs page lists several options to consider. Each has pros and cons (according to Perplexity): - next-intl: Pros: Middleware routing, TypeScript-first, great dev tools, production-ready Cons: Learning curve, less flexible for custom setups - next-international: Pros: Zero-config setup, simple API, excellent DX Cons: Younger project, smaller community - next-i18n-router: Pros: Clean URL routing, SEO-optimized, lightweight Cons: Manual translation handling required - paraglide-next: Pros: Compile-time safety, tiny bundles, blazing fast Cons: New ecosystem, fewer integrations - lingui: Pros: ICU message format, CLI extraction, framework-agnostic Cons: JSX macro setup, more configuration - tolgee: Pros: Visual translation editor, in-app editing, headless Cons: Paid tiers for scale, vendor dependency - next-intlayer: Pros: Edge runtime support, streaming-friendly Cons: Early development, limited documentation - gt-next: Pros: AI-powered translations, quick setup Cons: Relies on external translation service - i18next: Pros: Mature ecosystem, huge plugin library Cons: Heavy bundle, complex Next.js config I'm leaning toward i18next - its mature ecosystem and strong maintenance make it appealing. It should be reasonably easy to install and set up according to these pages: - https://github.com/i18next/next-i18next - https://www.locize.com/blog/i18n-next-app-router/
