MongoDB Basics: NoSQL for Modern Applications

What is MongoDB?

MongoDB stores data in BSON (binary JSON) format, offering schema-less flexibility and fast development cycles.

Installing MongoDB

Use the official website or run:

brew tap mongodb/brew
  brew install mongodb-community@6.0

Creating a Document

db.users.insertOne({
    name: "Alice",
    email: "alice@example.com",
    created_at: new Date()
  });

Querying Data

db.users.find({ name: "Alice" })

MongoDB works well with Node.js using the Mongoose library for schema validation.
