RESTful Web API Design with Node.js (Video 4)

This video tutorial explores how RESTful APIs utilize HTTP to access and manipulate collections and elements, and how remote procedures are called. It explains the concept of collections, their interfaces, and the use of HTTP methods like GET, POST, PUT, and DELETE. An example using a notes collection illustrates these methods. The video also discusses status codes, idempotency, and the role of elements in REST. Finally, it covers remote procedures and best practices for designing APIs.

What is a collection in RESTful APIs?

• A type of HTTP request

• A group of elements with the same representation

• A method for accessing data

• A single element with a unique representation

Which HTTP method is used to retrieve a list of elements from a collection?

• DELETE

• GET

• PUT

• POST

What status code is typically returned when a new element is successfully added to a collection?

• 500 Internal Server Error

• 201 Created

• 200 OK

• 404 Not Found

In REST, what does an element's endpoint include?

• The server's IP address

• The collection's name and the element's ID

• The element's ID only

• The collection's name only

What is a key guideline for naming endpoints for remote procedures in RESTful APIs?

• They should end with a noun

• They should end with a verb

• They should start with a number

• They should be in uppercase
