Connecting to a MongoDB Cluster

Discover how to connect your Deno application to a MongoDB cluster using MongoDB Atlas. Learn to create and configure a cluster, add user authentication, and modify your code to use persistent cloud storage. This lesson helps you transition from an in-memory database to a scalable, real-world database without changing your business logic.

We'll cover the following...
