Complete MongoDB Cheatsheet

Description

Every MongoDB command and pattern you need, in one quick-reference PDF.

No lengthy explanations — just clean, copy-paste-ready syntax for everything from basic CRUD to aggregation pipelines and Mongoose integration. Perfect for keeping open in a side tab while you code.

What’s covered:

✅ Core Concepts — SQL-to-MongoDB terminology mapping, document structure
✅ CRUD Operations — insert, find, update, delete + upsert pattern
✅ Query Operators — comparison ($gt, $in, $ne…), logical ($and, $or, $not)
✅ Array Query & Update Operators — $elemMatch, $all, $push, $addToSet, $pull
✅ Indexes — single field, compound, unique, text indexes + management commands
✅ Aggregation Pipeline — all major stages with syntax + accumulators ($sum, $avg, $push)
✅ $lookup & $unwind — joining collections, flattening arrays
✅ Mongoose (Node.js ODM) — connection, schema definition, CRUD shortcuts
✅ Real-world example — a complete “Top 5 Customers by Spend” aggregation query

3 pages. Dense, practical, zero fluff.

Great as a standalone quick-reference, or paired with the MongoDB Interview MCQs / Q&A Pack for complete interview prep.
