MongoDB, the most popular NoSQL database, we can count the number of documents in MongoDB Collection using the MongoDB collection.countDocuments() function. The mongodb module is used for connecting the MongoDB database as well as used for manipulating the collections and databases in MongoDB.
Installing module: You can install mongodb module using the following command.
npm install mongodb
Project Structure:
Running the server on Local IP: Data is the directory where MongoDB server is present.
mongod --dbpath=data --bind_ip 127.0.0.1
MongoDB Database:
Database:GFG
Collection:aayush
Following is the sample data stored in your database for this example.
Filename: index.js
JavaScript
// Requiring module
const MongoClient = require("mongodb");
// Connection URL
const url = 'mongodb://localhost:27017/';
// Database name
const databasename = "GFG";
MongoClient.connect(url).then((client) => {
const connect = client.db(databasename);
// Connect to collection
const collection = connect .collection("aayush");
// Replacing document with our match condition
collection.replaceOne({name:"aayush"},
{name:"aayushsaini"}).then((ans) => {
console.log("Successful");
}).then((err) => {
console.log(err);
})
}).catch((err) => {
// Printing the error message
console.log(err.Message);
})
Run index.js file using the following command:
node index.js
Output:
Following is our updated database after executing the above command.
