Should I use local MongoDB or MongoDB Atlas?
Atlas is easier for beginners since it is cloud-based and requires no local installation. Local MongoDB is fine for development. Either works; Atlas is recommended for learning since it is a managed cloud database with a free tier.

Install MongoDB (local or Atlas), install Mongoose with npm install mongoose, connect with mongoose.connect(connectionURI) from env vars, handle connection events, define schemas, create models, and perform CRUD operations.
Because Mongoose provides schemas, validation, middleware, and population. It prevents bugs by enforcing structure, makes the data model clear, and handles common patterns that the raw driver does not.
In an environment variable, never in code. Use dotenv to load .env files. Use different databases for development and production. This keeps secrets out of code and lets each environment use the right database.
