Full Stack Web Development MASTERY Course - Novice to Expert - Create Simple API in Node.js

This video tutorial guides viewers through creating a simple API using Node.js. It covers reusing code from previous lectures, integrating data from the News API, and testing API endpoints with Postman. The tutorial also explains handling JSON data, including parsing and displaying it on the client side. The video emphasizes using existing APIs for learning and demonstrates both asynchronous and synchronous file reading methods.

What is the primary purpose of reusing code from a previous lecture in this tutorial?

• To demonstrate a new concept

• To ensure code consistency

• To save time and effort

• To create a complex API

Why is it beneficial to use existing APIs like the News API when learning?

• They are more secure

• They simplify the learning process

• They provide a large amount of data

• They are free to use

What tool is recommended for testing APIs to ensure they work properly?

• Google Chrome

• Node.js

• Postman

• Visual Studio Code

What is the role of the FS module in Node.js?

• To parse JSON data

• To manage server responses

• To read and write files

• To handle HTTP requests

How can you display data fetched from a JSON file on the client's screen?

• Using document.write()

• Using response.end

• Using console.log

• Using alert()

What method is used to convert JSON data into a JavaScript object?

• JSON.toObject()

• JSON.convert()

• JSON.parse()

• JSON.stringify()

Why is it necessary to use the parse method on JSON data?

• To send it over the network

• To make it accessible as a JavaScript object

• To convert it into a string

• To encrypt the data

What is the advantage of using synchronous file reading over asynchronous in this context?

• It is faster

• It simplifies error handling

• It uses less memory

• It ensures the API is called only once

What status code indicates a successful API call?

• 100

• 200

• 300

• 400

What content type is specified for JSON data in HTTP headers?

• application/json

• text/plain

• application/xml

• text/html
