- 🔹 Configuration Management
What is Config Management?
Configuration management is the practice of structuring and centralizing application settings so they can be reused and maintained easily.
Example Structure
config/
├── dev.js
├── prod.js
└── index.js- config/index.js
module.exports = {
mongoURI: process.env.MONGO_URI,
jwtSecret: process.env.JWT_SECRET
};Benefits of Config Management
Cleaner project structure
Easy environment switching
Single source of truth
Better scalability
Development vs Production Configuration
Environment Flow
Local Machine → Dev Config
Cloud Server → Prod Config- 🔹 Secure Config Practices
Best Practices
Never hardcode credentials
Always use environment variables
Rotate secrets regularly
Use strong random secrets
Restrict access to production configs
❌ Bad Practice
const jwtSecret = "123456";✅ Good Practice
const jwtSecret = process.env.JWT_SECRET;
