The Complete MongoDB Guide

MongoDBDatabaseNoSQLJavaScript

MongoDB is a source-available cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with optional schemas.

Installation & Connection

Connect to MongoDB using the official Node.js driver or Mongoose ODM. Mongoose provides a straightforward, schema-based solution to model your application data.

CRUD Operations

MongoDB's CRUD operations are intuitive. Create documents with `insertOne` or `insertMany`, read with `find` and `findOne`, update with `updateOne` or `updateMany`, and delete with `deleteOne` or `deleteMany`.

Aggregation Pipeline

The aggregation pipeline is MongoDB's powerful data transformation framework. Chain stages like `$match`, `$group`, `$project`, `$sort`, and `$lookup` to analyze and transform your data.
