Node.js MongoDB Insert

Here is a clear and simple guide for Node.js MongoDB Insert operations using the official MongoDB Node.js Driver.

✅ Node.js MongoDB – Insert Documents

MongoDB allows you to insert one or multiple documents into a collection.

✅ 1. Install MongoDB Driver

✅ 2. Insert One Document (`insertOne`)

Example:

const { MongoClient } = require("mongodb");

const url = "mongodb://localhost:27017/";
const client = new MongoClient(url);

async function run() {
try {
await client.connect();
console.log("Connected to MongoDB");

const db = client.db("mydb");
const collection = db.collection("customers");

const data = { name: "John", address: "Highway 37" };

const result = await collection.insertOne(data);
console.log("Document Inserted:", result.insertedId);
} finally {
await client.close();
}
}

run();

const { MongoClient } = require("mongodb");

const url = "mongodb://localhost:27017/";

const client = new MongoClient(url);

async function run() {

try {

await client.connect();

console.log("Connected to MongoDB");

const db = client.db("mydb");

const collection = db.collection("customers");

const data = { name: "John", address: "Highway 37" };

const result = await collection.insertOne(data);

console.log("Document Inserted:", result.insertedId);

} finally {

await client.close();

}

run();

✅ 3. Insert Multiple Documents (`insertMany`)

Example:

const { MongoClient } = require("mongodb");

const url = "mongodb://localhost:27017/";
const client = new MongoClient(url);

async function run() {
try {
await client.connect();
console.log("Connected to MongoDB");

const db = client.db("mydb");
const collection = db.collection("customers");

const data = [
{ name: "John", address: "Highway 37" },
{ name: "Peter", address: "Lowstreet 4" },
{ name: "Amy", address: "Apple st 652" }
];

const result = await collection.insertMany(data);
console.log("Inserted Documents:", result.insertedCount);
} finally {
await client.close();
}
}

run();

const { MongoClient } = require("mongodb");

const url = "mongodb://localhost:27017/";

const client = new MongoClient(url);

async function run() {

try {

await client.connect();

console.log("Connected to MongoDB");

const db = client.db("mydb");

const collection = db.collection("customers");

const data = [

{ name: "John", address: "Highway 37" },

{ name: "Peter", address: "Lowstreet 4" },

{ name: "Amy", address: "Apple st 652" }

];

const result = await collection.insertMany(data);

console.log("Inserted Documents:", result.insertedCount);

} finally {

await client.close();

}

run();
