Answer
Connections use drivers or ORMs like MongoDB driver, Mongoose, or Sequelize with pooling for performance.
Quick Answer
Node.js database connections are typically managed with a connection pool — a set of pre-established connections shared across requests. Creating a new connection per request is slow; pools reuse existing ones. Libraries like pg (PostgreSQL), mysql2, and Mongoose manage this automatically. Configure pool size based on your database server's limits.
