Today I learned that...

Pushing API keys to GitHub accidentally is way more common than I thought — and it happened to me twice while building my AI travel chatbot! 😅


The fix is simple but easy to forget:

# .gitignore .env
.env file

GEMINI_API_KEY=your_key_here

This was useful because...It saved my Gemini API key from being exposed publicly. Always add .env to .gitignore BEFORE your first commit — not after!
