Smart-i18n

A Gulp-based CLI toolkit for modular, scalable i18n in JS/TS projects

Smart-i18n is a framework-agnostic internationalization (i18n) CLI toolkit that automates translation workflows in JavaScript and TypeScript projects. It is based on Gulp and designed to integrate seamlessly into apps built with Next.js, React, Vue, or other frontend/backend stacks.

• 🔄 Seamless translation file merging with old keys preserved
• 🌐 On-demand machine translation via Deep Translate (RapidAPI)
• 🔒 Safe TypeScript typings for all i18n keys
• 🧱 Modular Gulp tasks for fully scriptable i18n pipelines
• 🧰 CLI-based, works via yarn smart-i18n, npx smart-i18n, or direct Gulp
