MongoDB is a database designed to scale applications. Read all about it here.
The Node.js version has to be compatible with MongoDB.
This driver will help you interact easily with MongoDB from within Node.js apps. To install the driver correctly, read the official documentation.
Using Atlas will be super easy as it is MongoDB’s fully-managed database-as-a-service. Create a cluster in the Atlas tier. After it has been created, you can upload data.
In Atlas, go to the cluster. Click connect to open up The Cluster Connection Wizard. Add your current IP address and create a MongoDB user. Further, connect the app by selecting the node driver version.
