Connect Mongodb Atlas to nodejs and Express Server
Learn how to connect Mongodb Atlas to a Node Express backend.
We will be doing everything from scratch, making our free cluster and database in the cloud. Then we configure database access and make a user to access it. The way we connect with Mongodb Atlas is through a connection string, that we store in a .env file locally in our backend project.
When that is done we make our node express server with two endpoints. One GET route for getting all the entities (customers) and creating a new one though a POST endpoint. Inside our project we also make a schema of the customer object we will be working with.
To query our backend we use Postman, which is a very useful tool for this, and you can download it here:
