This tutorial covers the two essential MongoDB commands for creating data: insertOne and insertMany. Learn how to add a single document or multiple documents to your collection using the Mongo Shell (mongosh).
What you will learn:
db.collection.insertOne(): The command to add a single JSON document to a collection. We'll show you what it returns, including the new _id.
db.collection.insertMany(): How to add multiple documents at once by passing an array of objects. This is much more efficient for bulk data.
How MongoDB automatically creates a database or collection if it doesn't already exist.
Example insertOne: db.users.insertOne({ name: "Alice", age: 30, city: "New York" })
Example insertMany: db.users.insertMany([ { name: "Bob", age: 25 }, { name: "Charlie", age: 35 } ])
