📦 API Reference

LingoTranslator

import { LingoTranslator } from './translator.js';

const translator = new LingoTranslator(apiKey);

// Translate text
const result = await translator.translate(text, 'en', 'es');

// Batch translate
const results = await translator.batchTranslate(texts, 'en', ['es', 'fr']);

// Detect language
const lang = await translator.detectLanguage(text);

// Get supported languages
const langs = await translator.getSupportedLanguages();

🔐 Security

• ✅ API keys stored locally in .env.local (not committed)
• ✅ Never exposed in public files
• ✅ GitHub Actions uses Secrets (encrypted)
• ✅ No data sent to third parties except Lingo.dev
• ✅ Uses HTTPS for all API calls

📊 Performance

• Translation Speed: ~2-5 seconds per file
• Caching: 50-70% faster on incremental updates
• Memory Usage: <100MB typical
• API Efficiency: Smart batching reduces API calls

💰 Cost Estimation

Based on Lingo.dev pricing:

• Free Tier: ~10,000 words/month
• Small Project (100KB docs): ~$5-10/month
• Medium Project (1MB docs): ~$50-100/month
• Large Project (10MB docs): ~$500-1000/month

🐛 Troubleshooting

"API Key not found"

# Check .env.local exists
cat .env.local

# Should show:
# LINGODOTDEV_API_KEY=your_key

# If missing, create it:
echo "LINGODOTDEV_API_KEY=your_key" > .env.local

"No markdown files found"

# Verify source directory structure
find docs/en -name "*.md"

# Should show your markdown files

"Translation failed - Invalid credentials"

# 1. Verify API key is correct
npm run status

# 2. Get new key from lingo.dev if expired
# 3. Update .env.local
# 4. Restart: npm run dev
# 5. Try again: npm run translate
