Web Development with Node.JS and MongoDB (Video 23)

This video tutorial covers how Express JS aids in building RESTful APIs, including planning and structuring APIs, handling errors, and exploring authentication methods. It explains the four levels of REST, the use of middleware, and the importance of choosing appropriate data formats and authentication methods. The video concludes with a summary and a preview of the next topic, which is consuming REST APIs on the server side.

What is one of the main advantages of using Express JS for building APIs?

• It is only compatible with REST APIs.

• It requires no coding knowledge.

• It provides built-in methods to solve common problems.

• It automatically generates API documentation.

How can you reach the third level of REST using Express JS?

• By using OAuth.

• By using HTTP methods.

• By using JSON data format.

• By using API keys.

What is a common data format used in APIs, as mentioned in the video?

• XML

• CSV

• YAML

• JSON

What should be included in error messages returned by an API?

• A detailed error message with code, status, title, and details.

• Just the error title.

• Only the HTTP status code.

• The error code and status only.

Which authentication method is recommended for third-party services?

• HTTP Basic

• API Key

• OAuth 2.0

• JWT

Why is it important to use SSL in API communication?

• It is required for all REST APIs.

• It reduces the size of data packets.

• It improves security significantly.

• It speeds up the API response time.

What is a key disadvantage of using HTTP Basic authentication?

• It requires a lot of server resources.

• It only works with JSON data.

• It is too complex to implement.

• It is not very secure.
