Once you have installed the mongodb
module using the npm
command, you can begin accessing MongoDB from your Node.js applications by opening up a connection to the MongoDB server. The connection acts as your interface to create, update, and access data in the MongoDB database.
The best way to access MongoDB is through the MongoClient
class in the mongodb
module. This class provides very simple ways to create connections to MongoDB. There are two main methods you can use. One is to create an instance of the MongoClient
object and then use that object to create and manage the MongoDB connection. The other method is to use a connection string to make a connection. Both of these options work well.
