Summary  
This chapter explains how to configure and connect to a managed cloud-hosted NoSQL database service by obtaining and using a connection string in your application.

General domain of usage  
Cloud-based data storage for applications


To use MongoDB in your application, you need a running database.

The easiest way to get started is by using MongoDB Atlas. It is a cloud service that hosts your database, so you do not need to install anything locally.

You create an account, set up a cluster, and create a database. After that, you will get a connection string that allows your application to connect to MongoDB.

MongoDB Atlas is recommended because it is simple to set up and works the same way as real production environments.


Learn how to store and manage data in backend applications using MongoDB and Mongoose. Connect your Express API to a database and perform create, read, update, and delete operations. Build real data-driven backend functionality and move beyond in-memory storage.
