ttag

⚠️ This project was previously named c-3po. Some of the talks, presentations, and documentation may reference it with both names.

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
• It can precompile translations on a build step.
• Plurals support ngettext.
• It can be integrated in any build tool that works with babel.
• Has a builtin validation for translated strings format.
• It can use any default locale in sources (not only English).
• Handles React (jsx) translations.
• Can be easily integrated with Create React App. CRA doc

Usage example

import { t, ngettext, msgid } from 'ttag'
 
// 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)
