Node.js API Masterclass with Express and MongoDB - Fetching Bootcamps – GET

This video tutorial covers how to insert and fetch boot camps from a database using async/await with Mongoose. It explains the implementation of methods to retrieve all boot camps and a single boot camp by ID, including error handling for invalid or non-existent IDs. The tutorial emphasizes the importance of handling promises and responses correctly to avoid errors like 'headers already sent'. Future videos will cover updating and deleting boot camps.

What is the purpose of making the get boot camps method asynchronous?

• To make the code run faster

• To handle promises returned by Mongoose methods

• To improve code readability

• To avoid using callbacks

What HTTP status code is returned when all boot camps are successfully fetched?

• 200

• 400

• 404

• 500

Which method is used to find a single boot camp by its ID?

• findByLocation

• findByName

• findByTitle

• findById

What happens if a correctly formatted ID that does not exist in the database is used?

• A 400 status code is returned

• A 200 status code is returned

• A 404 status code is returned

• A 500 status code is returned

Why is it important to return the first response in a try block?

• To ensure the headers are not sent multiple times

• To handle exceptions properly

• To prevent the function from executing further

• To improve code readability

What is the result if an incorrectly formatted object ID is used?

• A 500 status code is returned

• A 404 status code is returned

• A 200 status code is returned

• A 400 status code is returned

What is the purpose of creating an error handler for responses?

• To handle database connections

• To increase the speed of the application

• To simplify the code by avoiding try-catch blocks

• To ensure all errors are logged
