mongodb-core

What is mongodb-core?

The mongodb-core package is a low-level driver for MongoDB that provides the core functionality for interacting with MongoDB databases. It is used internally by the higher-level mongodb package but can be used directly for more fine-grained control over MongoDB operations.

What are mongodb-core's main functionalities?

Connecting to MongoDB

This feature allows you to establish a connection to a MongoDB server. The code sample demonstrates how to create a new MongoClient instance and connect to a MongoDB server running on localhost.

const MongoClient = require('mongodb-core').MongoClient;
const client = new MongoClient('mongodb://localhost:27017');
client.connect((err) => {
  if (err) throw err;
  console.log('Connected to MongoDB');
  client.close();
});

Performing CRUD Operations

This feature allows you to perform CRUD (Create, Read, Update, Delete) operations on a MongoDB database. The code sample demonstrates how to insert a document into a collection.

const MongoClient = require('mongodb-core').MongoClient;
const client = new MongoClient('mongodb://localhost:27017');
client.connect((err) => {
  if (err) throw err;
  const db = client.db('test');
  const collection = db.collection('documents');
  collection.insertOne({ a: 1 }, (err, result) => {
    if (err) throw err;
    console.log('Document inserted');
    client.close();
  });
});

Handling Replication

This feature allows you to handle MongoDB replication. The code sample demonstrates how to connect to a MongoDB replica set.

const ReplSet = require('mongodb-core').ReplSet;
const replSet = new ReplSet([{ host: 'localhost', port: 27017 }], { setName: 'rs0' });
replSet.on('connect', () => {
  console.log('Connected to replica set');
  replSet.destroy();
});
replSet.connect();

Other packages similar to mongodb-core

mongodb

The mongodb package is a higher-level driver for MongoDB that builds on top of mongodb-core. It provides a more user-friendly API and additional features such as connection pooling, schema validation, and more. It is the recommended package for most users.

mongoose

Mongoose is an Object Data Modeling (ODM) library for MongoDB and Node.js. It provides a higher-level abstraction over the MongoDB driver, including schema-based data validation, middleware, and more. It is ideal for applications that require a structured data model.

monk

Monk is a minimalistic wrapper around the MongoDB driver that provides a simple and easy-to-use API for interacting with MongoDB. It is less feature-rich than mongoose but offers a more straightforward approach for basic CRUD operations.
