Backend Development with Node.js, Express, and MongoDB

This tutorial covers the basics of backend development by creating a CRUD API using Node.js, Express, and MongoDB. It guides through setting up the development environment, creating a simple CRUD app, and testing APIs with tools like Insomnia and Postman. The tutorial also explains connecting to MongoDB, implementing CRUD operations, organizing code with routes and controllers, and deploying the project to GitHub.

What is the first step to verify if Node.js is installed correctly?

• Run 'node -v' in the terminal

• Open Visual Studio Code

• Create a new project folder

• Install Express

Which command is used to initialize a new npm project?

• npm start

• npm init -y

• npm install

• npm run serve

What is the purpose of the 'serve' script in package.json?

• To run the Node.js application

• To initialize the project

• To start the MongoDB server

• To install dependencies

Which tool is recommended for testing APIs locally?

• Visual Studio Code

• Node.js

• MongoDB Atlas

• Insomnia

What is the purpose of Mongoose in a Node.js application?

• To connect and interact with MongoDB

• To manage npm packages

• To test APIs

• To create a server

What is the purpose of the 'app.get' method in the API?

• To create a new product

• To delete a product

• To retrieve products from the database

• To update an existing product

How can you retrieve a specific product using its ID in the API?

• By using 'app.post' method

• By using 'app.get' method with '/:id' parameter

• By using 'app.put' method

• By using 'app.delete' method

Which HTTP method is used to update a product in the API?

• PUT

• POST

• GET

• DELETE

What is the purpose of the 'try and catch' block in the update API?

• To handle errors during the update process

• To delete a product

• To handle asynchronous operations

• To create a new product

Why is it important to separate routes and controllers in the API code?

• To avoid using external libraries

• To reduce the number of lines of code

• To increase the execution speed

• To make the code more organized and maintainable
