Serving Products – Back-end Routes

The video tutorial guides viewers through setting up a simple backend server using Node.js and Express. It covers initializing the backend, creating routes to serve product data, configuring API endpoints, and handling requests for single products. The tutorial also discusses integrating the backend with a React frontend, emphasizing the transition from using CommonJS to ES modules. The focus is on creating a basic server to serve JSON data, with plans to expand functionality in future lessons.

What is the first step in setting up a backend server with Node.js and Express?

• Create a frontend folder

• Initialize package.json

• Install MongoDB

• Set up a database

Where should the package.json file be initialized for the server setup?

• In the data folder

• In the backend folder

• In the frontend folder

• In the root directory

What is the purpose of creating a data folder in the backend setup?

• To copy product data from the frontend

• To store frontend components

• To manage user authentication

• To hold server configuration files

What command is used to start the server after setting up the entry point?

• npm start

• node start

• npm run server

• node server.js

What does the basic API route initially return to the client?

• An error message

• A simple message indicating the API is running

• A JSON object

• A list of products

How is product data served from the backend to the frontend?

• By using a static HTML file

• By creating API routes that return JSON data

• By directly accessing the database

• By embedding data in the frontend code

What is the method used to fetch a single product by its ID?

• Using a SQL query

• Using the find method on the product array

• Using a loop to iterate through all products

• Using a direct database call
