c-3po

Modern javascript i18n localization library based on es6 tagged templates and the good old GNU gettext

Key features

• Uses es6 template literals for string formatting (no need for sprintf).
• Contexts support
• Can precompile translations on a build step.
• Plurals support ngettext.
• Can be integrated in any build tool that works with babel.
• Has options for both efficient development and production setups.
• Has a builtin validation for translated strings format.
• Can use any default locale in sources (not only English).
• Handles React (jsx) translations.

Usage example

import { t, ngettext, msgid } from 'c-3po'

// formatted strings
const name = 'Mike';
const helloMike = t`Hello ${name}`;

// plurals (works for en locale out of the box)
const n = 5;
const msg = ngettext(msgid`${ n } task left`, `${ n } tasks left`, n)
