Polyglot.js is a tiny I18n helper library for JavaScript that runs in both the browser and Node.js (CommonJS) environments. It manages dictionaries of already-translated phrases and provides message lookup with interpolation and pluralization rules, while remaining agnostic to any translation backend or service.
Use cases
- translate my javascript app's ui strings into multiple languages
- handle pluralization rules for different languages in js
- interpolate variables into translated messages in the browser
- manage per-locale phrase dictionaries for express requests
- add lightweight i18n to a backbone or node app without a heavy framework
- pass localized strings from a rails backend into client-side javascript
When to choose
- You need a small, lightweight helper for string lookup, interpolation, and locale-aware pluralization in browser or Node code
- You already obtain translations from another backend, service, or team and only need a way to store and retrieve phrases
- You need isolated per-request locale instances on a server (e.g., Express) without concurrent requests clobbering each other's phrases
When to avoid
- You expect the tool to translate text for you — it performs no translation and has no translation backend integration
- You need full-featured i18n such as ICU MessageFormat, date/number/currency formatting, or message catalog extraction tooling
- You want framework-level locale routing or built-in SSR language switching rather than a phrase-lookup helper
