Node.js API Masterclass with Express and MongoDB - Create Bootcamp – POST

This video tutorial covers setting up basic CRUD functionality for a bootcamp application using Express and Mongoose. It demonstrates how to handle JSON requests with Postman, manage request bodies using Express middleware, and insert data into a MongoDB database. The tutorial also addresses error handling with try-catch blocks and discusses future refactoring plans for cleaner code.

What is the first step in setting up CRUD functionality for bootcamps?

• Implementing user authentication

• Designing the user interface

• Creating the bootcamp model

• Setting up a database

Why is it beneficial to create a preset for JSON content type in Postman?

• It allows for faster data retrieval

• It simplifies the process of adding headers

• It enhances data security

• It reduces server load

What middleware is used to handle request bodies in Express?

• BodyParser

• Express.json

• Mongoose

• Cors

What is the purpose of using async/await in handling promises?

• To increase execution speed

• To simplify promise handling

• To handle errors more effectively

• To make code synchronous

What happens if a field not defined in the Mongoose model is sent in a request?

• It is added to the database

• It is ignored and not added

• It causes an error

• It overwrites existing data

What error occurs when trying to insert a duplicate entry in the database?

• Type error

• Validation error

• Duplicate key error

• Syntax error

How can unhandled promise rejections be managed in the code?

• Using async/await

• Using setTimeout

• Using try/catch blocks

• Using console.log

What status code is returned for a successful resource creation?

• 200

• 500

• 201

• 400

What is the advantage of using a custom error handler?

• It speeds up error resolution

• It eliminates the need for try/catch in every method

• It improves error logging

• It reduces code complexity

What is the next step after inserting bootcamp data into the database?

• Optimizing database queries

• Creating a user interface

• Fetching data through routes

• Implementing user authentication
