 What is MongoDB

 

MongoDB is a popular open-source NoSQL (non-relational) database management system. NoSQL means no structure like it is look like an object while in SQL it is a structure query language like SELECT CustomerName, City FROM Customers; (The SELECT statement is used to select data from a database.) But NoSQL database is useless...NOT completely because of whenever we want add extra column in database then it is possible through NoSQL MongoDB.

{
  "_id": {
    "$oid": "659ad46e0382148123c82841"
  },
  "name": "moto G60",
  "brand": "motorola",
  "price": 16500,
  "category": "mobile"
}

 

 

MongoDB is a type of database that helps store and manage large amounts of data in a flexible and scalable way. Unlike SQL, MongoDB doesn't require a fixed structure for the data, allowing you to store information in a more versatile format.

• MongoDB is a NoSQL database.
• The data stored in a collection
• Collection don't have row and columns
• Data is stored in the form of object.

 Insert Data from MongoDB

 

We will write code of insert data in separate file so first make a new file for inserting data

 

 

 

const dbConnect = require('./mongodb/mongodb')


const insert = () => {
    console.log("Insert Function")
}


insert();

 

 

 

 

Run with nodemon insert.js

 

Whole Code 

 

 

const dbConnect = require("./mongodb/mongodb");

const insert = async () => {
  const db = await dbConnect();
  const result = await db.insertOne({
    name: "note 5",
    brand: "vivo",
    price: 2500,
    category: "mobile",
  });

  console.log("data inserted");
  console.log(result);
};

insert();

 

 

if you want insert too much data in one command you can use insertMany() function.

 

InsertMany()

 

// const dbConnect = require("./mongodb/mongodb");

// const insert = async () => {
//   const db = await dbConnect();
//   const result = await db.insertOne({
//     name: "note 5",
//     brand: "vivo",
//     price: 2500,
//     category: "mobile",
//   });

//   console.log("data inserted");
//   console.log(result);
// };

// insert();

const dbConnect = require("./mongodb/mongodb");

const insert = async () => {
  const db = await dbConnect();
  const result = await db.insertMany([
    {
      name: "note 5",
      brand: "vivo",
      price: 2500,
      category: "mobile",
    },
    {
      name: "micro",
      brand: "micromax",
      price: 4500,
      category: "mobile",
    },
  ]);

  console.log("data inserted");
  console.log(result);
};

insert();

 

 

 

output - data inserted, acknowledged : true, insertCount: 2
