Overview
What i18next / react-i18next does
i18next supplies software internationalization primitives for rendering localized content across web, mobile and desktop environments. react-i18next connects those primitives to React components. Translation authoring, collaboration and professional translation management are outside the core library and may be handled with separate tools.
Buying context
Fit and constraints
- Best for
- Development teams building locale-aware JavaScript applications that need translation rendering, plural and context handling, interpolation, formatting, and extensible language or resource loading.
- Relevant constraints
- Requires developers to integrate and configure the libraries in their applications; translation resources must be supplied or loaded through configured backends.
- Plural behavior depends on Intl.PluralRules support; environments lacking it need a polyfill for full language-specific plural rules.
- The ecosystem includes separate plugins and services; their availability or functionality should not be attributed to the core libraries.
