PolingoUniversal gettext-powered translations for modern JavaScript

Load .po/.mo catalogs once and translate everywhere — Node.js, browsers, and edge runtimes.

Standard gettext catalogs

Work with existing .po/.mo files and keep translators in their established tooling.

Scaffold a new app with `pnpm create polingo-app` or upgrade an existing codebase via `npx polingo init`.

Share the same translator across Node.js backends, web apps, edge functions, and tests.

Use filesystem, fetch, or custom loaders with optional caching and hot reload support.

Plug into Express or Fastify to auto-detect locales and expose translators per request.

Strict types, generics for configuration, and ergonomic developer tooling.

In-memory or localStorage caching, graceful fallbacks, and robust pluralization handling.
