i18n

A lightweight Node.js translation module that stores language files in JSON format, supporting dynamic on-the-fly string addition. Current stable version is 0.15.3 (last updated July 2024), with a moderate release cadence. Key differentiators include simplicity (no extra parsing), integration with Express via middleware, and support for both singleton and instance patterns. It provides common __('...') syntax for translation lookups, automatic locale detection from Accept-Language headers, and CLI/script usage. Unlike more complex solutions like i18next, this library is minimal with no external dependencies, but it lacks features like pluralization, interpolation, and loading from remote backends.
