Express.js CRUD API Tutorial | Secure Database Connection (.env)
.env file should never be shared
The .env file contains sensitive information such as database username, password, and connection strings.
If you upload .env to GitHub or share it publicly, your credentials can be exposed and misused.
Always keep .env private and add it to .gitignore.
Database creation
Before running the app, we first create a database (e.g., todo_db) in MySQL/MongoDB.
This database stores all the tasks (todos).
The app then connects to this database (using values from .env) to perform CRUD operations.
