Modern JavaScript from the Beginning - Second Edition - Database Queries

The video tutorial guides viewers through creating a CRUD REST API using a database. It covers setting up the server, importing models, and implementing GET, POST, PUT, and DELETE requests. The tutorial emphasizes using async/await for handling asynchronous operations and demonstrates testing the API with Postman. By the end, viewers will have a fully functional API ready for front-end integration.

What is the first step in integrating a database with your application?

• Running the server

• Setting up a frontend

• Importing the model

• Writing GET requests

Which method is used to retrieve documents from the database?

• findById

• find

• getAll

• retrieve

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

• To handle promises more efficiently

• To avoid using try-catch blocks

• To make the code synchronous

• To speed up the server

When adding a new idea to the database, which fields are necessary?

• ID and date

• Text, tag, and username

• Date and username

• Text and ID

What method is used to save a new object to the database?

• insert

• store

• save

• add

Which method is used to update an existing document in the database?

• change

• update

• modify

• findByIdAndUpdate

What does setting 'new' to true in findByIdAndUpdate do?

• Ignores the update if the document is not found

• Returns the old document

• Deletes the document if not found

• Creates a new document if it doesn't exist

Which method is used to delete a document from the database?

• erase

• findByIdAndDelete

• delete

• remove

What is the final step after completing the CRUD operations in the backend?

• Creating a frontend

• Writing documentation

• Deploying the server

• Testing the API

What is the significance of having a full CRUD REST API?

• It allows for data persistence

• It speeds up the server

• It eliminates the need for a frontend

• It reduces code complexity
