MongoDB is a free and open-source NoSQL document-oriented database. It is classified as a NoSQL database because it does not rely on a fixed schema and does not use SQL as its query language. Instead, MongoDB stores data in BSON format (binary JSON) and uses a query language that is similar to JSON. This allows for more flexible and dynamic data modeling, making it a popular choice for applications that handle large amounts of unstructured data. MongoDB is also known for its scalability and performance, which makes it a good option for high-traffic web and mobile applications. Additionally, MongoDB can be easily distributed over multiple servers, which allows for horizontal scaling. It can run on a variety of operating systems and supports various programming languages such as JavaScript, C++, C#, Java, Python, and more.

For server and runtime version compatibility matrices, please refer to the following links:

Component Support Matrix

The following table describes add-on component version compatibility for the Node.js driver. Only packages with versions in these supported ranges are stable when used in combination.

Component mongodb@3.x mongodb@4.x mongodb@5.x mongodb@6.x
bson ^1.0.0 ^4.0.0 ^5.0.0 ^6.0.0
bson-ext ^1.0.0 || ^2.0.0 ^4.0.0 N/A N/A
kerberos ^1.0.0 ^1.0.0 || ^2.0.0 ^1.0.0 || ^2.0.0 ^2.0.1
mongodb-client-encryption ^1.0.0 ^1.0.0 || ^2.0.0 ^2.3.0 ^6.0.0
mongodb-legacy N/A ^4.0.0 ^5.0.0 ^6.0.0
@mongodb-js/zstd N/A ^1.0.0 ^1.0.0 ^1.1.0

Typescript Version

We recommend using the latest version of typescript, however we currently ensure the driver's public types compile against typescript@4.1.6.
This is the lowest typescript version guaranteed to work with our driver: older versions may or may not work - use at your own risk.
Since typescript does not restrict breaking changes to major versions we consider this support best effort.
If you run into any unexpected compiler failures against our supported TypeScript versions please let us know by filing an issue on our JIRA.


The recommended way to get started using the Node.js 5.x driver is by using the npm (Node Package Manager) to install the dependency in your project.

After you've created your own project using npm init, you can run:

npm install mongodb
# or ...
yarn add mongodb

This will download the MongoDB driver and add a dependency entry in your package.json file.

If you are a Typescript user, you will need the Node.js type definitions to use the driver's definitions:

npm install -D @types/node

Driver Extensions

The MongoDB driver can optionally be enhanced by the following feature packages:

Maintained by MongoDB:

Some of these packages include native C++ extensions.
Consult the trouble shooting guide here if you run into compilation issues.

Third party:

Quick Start

This guide will show you how to set up a simple application using Node.js and MongoDB. Its scope is only how to set up the driver and perform the simple CRUD operations. For more in-depth coverage, see the official documentation.

Create the package.json file

First, create a directory where your application will live.

mkdir myProject
cd myProject

Enter the following command and answer the questions to create the initial structure for your new project:

npm init -y

Next, install the driver as a dependency.

npm install mongodb

Start a MongoDB Server

For complete MongoDB installation instructions, see the manual.

  1. Download the right MongoDB version from MongoDB
  2. Create a database directory (in this case under /data).
  3. Install and start a mongod process.
mongod --dbpath=/data

You should see the mongod process start up and print some status information.

Connect to MongoDB

Create a new app.js file and add the following code to try out some basic CRUD
operations using the MongoDB driver.

Add code to connect to the server and the database myProject:

NOTE: Resolving DNS Connection issues

Node.js 18 changed the default DNS resolution ordering from always prioritizing ipv4 to the ordering
returned by the DNS provider. In some environments, this can result in localhost resolving to
an ipv6 address instead of ipv4 and a consequent failure to connect to the server.

This can be resolved by:

  • specifying the ip address family using the MongoClient family option (MongoClient(<uri>, { family: 4 } ))
  • launching mongod or mongos with the ipv6 flag enabled (--ipv6 mongod option documentation)
  • using a host of in place of localhost
  • specifying the DNS resolution ordering with the --dns-resolution-order Node.js command line argument (e.g. node --dns-resolution-order=ipv4first)
const { MongoClient } = require('mongodb');
// or as an es module:
// import { MongoClient } from 'mongodb'

// Connection URL
const url = 'mongodb://localhost:27017';
const client = new MongoClient(url);

// Database Name
const dbName = 'myProject';

async function main() {
  // Use connect method to connect to the server
  await client.connect();
  console.log('Connected successfully to server');
  const db = client.db(dbName);
  const collection = db.collection('documents');

  // the following code examples can be pasted here...

  return 'done.';

  .finally(() => client.close());

Run your app from the command line with:

node app.js

The application should print Connected successfully to server to the console.

Insert a Document

Add to app.js the following function which uses the insertMany
method to add three documents to the documents collection.

const insertResult = await collection.insertMany([{ a: 1 }, { a: 2 }, { a: 3 }]);
console.log('Inserted documents =>', insertResult);

The insertMany command returns an object with information about the insert operations.

Find All Documents

Add a query that returns all the documents.

const findResult = await collection.find({}).toArray();
console.log('Found documents =>', findResult);

This query returns all the documents in the documents collection.
If you add this below the insertMany example you'll see the document's you've inserted.

Find Documents with a Query Filter

Add a query filter to find only documents which meet the query criteria.

const filteredDocs = await collection.find({ a: 3 }).toArray();
console.log('Found documents filtered by { a: 3 } =>', filteredDocs);

Only the documents which match 'a' : 3 should be returned.

Update a document

The following operation updates a document in the documents collection.

const updateResult = await collection.updateOne({ a: 3 }, { $set: { b: 1 } });
console.log('Updated documents =>', updateResult);

The method updates the first document where the field a is equal to 3 by adding a new field b to the document set to 1. updateResult contains information about whether there was a matching document to update or not.

Remove a document

Remove the document where the field a is equal to 3.

const deleteResult = await collection.deleteMany({ a: 3 });
console.log('Deleted documents =>', deleteResult);

Index a Collection

Indexes can improve your application's
performance. The following function creates an index on the a field in the
documents collection.

const indexName = await collection.createIndex({ a: 1 });
console.log('index name =', indexName);

For more detailed information, see the indexing strategies page.

Error Handling

If you need to filter certain errors from our driver we have a helpful tree of errors described in etc/notes/

It is our recommendation to use instanceof checks on errors and to avoid relying on parsing error.message and strings in your code.
We guarantee instanceof checks will pass according to semver guidelines, but errors may be sub-classed or their messages may change at any time, even patch releases, as we see fit to increase the helpfulness of the errors.

Any new errors we add to the driver will directly extend an existing error class and no existing error will be moved to a different parent class outside of a major release.
This means instanceof will always be able to accurately capture the errors that our driver throws.

const client = new MongoClient(url);
await client.connect();
const collection = client.db().collection('collection');

try {
  await collection.insertOne({ _id: 1 });
  await collection.insertOne({ _id: 1 }); // duplicate key error
} catch (error) {
  if (error instanceof MongoServerError) {
    console.log(`Error worth logging: ${error}`); // special case for some reason
  throw error; // still want to crash

Nightly releases

If you need to test with a change from the latest main branch our mongodb npm package has nightly versions released under the nightly tag.

npm install mongodb@nightly

Nightly versions are published regardless of testing outcome.
This means there could be sematic breakages or partially implemented features.
The nightly build is not suitable for production use.
