📦 API Reference



$3

javascript

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



$3

bash

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

$3

bash

Verify source directory structure

find docs/en -name "*.md"



Should show your markdown files

$3

bash

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





$3



1. Go to: Settings → Actions → General

2. Select: "Read and write permissions"

3. Check: "Allow GitHub Actions to create pull requests"

4. Save and retry
