Using the insertOne Method in MongoDB

📖 Scenario: You are managing a small library database. You want to add new books to the collection one by one.

🎯 Goal: Learn how to use the insertOne method to add a single document (book) to a MongoDB collection.

📋 What You'll Learn

Create a document for a book with specific fields.

Use the insertOne method to add the book document to the books collection.

Store the result of the insertion in a variable called result.

💡 Why This Matters

💼 Career

Knowing how to insert documents into MongoDB collections is a fundamental skill for backend developers and database administrators.

1

Create the books collection variable

Create a variable called books and assign it to the MongoDB collection named libraryBooks.

MongoDB

// Create the books collection variable
// Your code here

Need a hint?

Use db.collection('collectionName') to get the collection.

2

Create a book document

Create a variable called newBook and assign it an object with these exact fields and values: title: 'The Great Gatsby', author: 'F. Scott Fitzgerald', year: 1925.

MongoDB

const books = db.collection('libraryBooks');
// Create the newBook document with title, author, and year
// Your code here

Need a hint?

Create a JavaScript object with the given keys and values.

3

Insert the book document using insertOne

Use the insertOne method on the books collection to insert the newBook document. Store the result in a variable called result.

MongoDB

const books = db.collection('libraryBooks');
const newBook = { title: 'The Great Gatsby', author: 'F. Scott Fitzgerald', year: 1925 };
// Insert newBook into books collection and save result
// Your code here

Need a hint?

Call insertOne on books with newBook as argument.

4

Confirm the insertion result

Add a line to check if the insertion was successful by accessing result.insertedId.

MongoDB

const books = db.collection('libraryBooks');
const newBook = { title: 'The Great Gatsby', author: 'F. Scott Fitzgerald', year: 1925 };
const result = books.insertOne(newBook);
// Access result.insertedId to confirm insertion
// Your code here

Need a hint?

Use dot notation to get insertedId from result.
