Package Exports

@tuhama/translation-manager
@tuhama/translation-manager/src/server.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@tuhama/translation-manager) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Translation Manager UI 🌍

A modern, web-based interface for managing i18n translation files in React and other JavaScript projects. Now with AI-Friendly features and an AI Skill File to make localization faster and more accurate.

[!TIP] This project is AI-Ready. AI agents can use the included translations.skill to automatically audit and manage your translations.

Features

Modern UI: Dark mode, glassmorphism, and smooth animations.
AI-Powered Translation: Support for OpenAI (GPT-4o), Google Gemini, and Google Cloud Translate.
Context-Aware Scanning: Extracts code snippets where translation keys are used, providing crucial context for AI translations.
Missing Keys Detection: Identifies translation keys used in source code but missing from files.
Cleanup Tool: Detects and batch-removes unused translation keys.
Normalization: Synchronizes keys across all languages and sorts them alphabetically with one click.
Export/Import: Export all missing translations to an AI-Friendly JSON file (including code context) for external translation.
CLI Status: Machine-readable JSON output for project health monitoring.
Tree View: Easy navigation and management of translation keys.
Zero Config: Auto-detects common locales folders.

Installation

Add it as a devDependency to your project:

npm install -g @tuhama/translation-manager

Or run directly with npx:

npx @tuhama/translation-manager

Usage

🤖 AI-Friendly Localization

The manager now extracts the surrounding code for every translation key it finds. This context is passed to AI models (like OpenAI or Gemini) to ensure highly accurate translations that respect your code's intent.

📤📥 Export/Import (AI-Enhanced)

You can export all missing translation keys to a single JSON file. This export is AI-Ready, containing code snippets for each key so you can feed it to an LLM for context-aware translations.

📊 CLI Status

Check your translation coverage programmatically:

npx @tuhama/translation-manager status

Outputs a machine-readable JSON summary of missing keys, coverage percentage, and project health.

⚠️ Missing Keys Detection

The application automatically scans your source code for translation keys used (e.g., t('key.name')) but missing from your translation files. Click the "Missing" button in the sidebar to review and create them instantly.

🪄 Auto-Translation

Configure Google Cloud, OpenAI, or Gemini in the settings to enable auto-translation. Use the "Source-to-All" button in the editor to quickly populate all languages.

Configuration

You can optionally create a translation.config.json in your project root:

Using OpenAI (Recommended for AI Quality)

{
  "path": "src/locales",
  "aiTranslate": {
    "provider": "openai",
    "apiKey": "your-openai-api-key",
    "model": "gpt-4o"
  }
}

Using Google Cloud Translate

{
  "path": "src/locales",
  "googleTranslate": {
    "projectId": "your-google-cloud-project-id"
  }
}

Development

To work on this repo:

npm install
cd web && npm install
npm run dev (starts both the API and the Vite UI)

Limitations

Dynamic Keys: Highly dynamic keys (e.g. t(someVar + '.key')) may not be detected by the "Missing Keys" tool.
Namespaces: Currently optimized for single-namespace or default-namespace projects.
