Data Seed Script

The video tutorial explains how to create a database seeder using Mongoose for importing and destroying sample data of users and products. It covers importing necessary modules, setting up the environment, and defining asynchronous functions to handle data operations. The tutorial also demonstrates executing these operations using NPM scripts and provides cautionary advice on data replacement during development.

What is the primary purpose of creating a database seeder script?

• To optimize database queries

• To import and manage sample data easily

• To connect the application to the server

• To enhance the user interface

Which library is essential for using models in the seeder script?

• Express

• React

• Mongoose

• Axios

Why are the import and destroy functions asynchronous?

• Because they handle large files

• Because they interact with a database

• Because they are part of the front-end

• Because they use synchronous methods

What is the purpose of the 'delete many' method in the import data function?

• To update existing data

• To delete specific records

• To clear all records in a collection

• To add new records

How is the admin user associated with all products in the import data function?

• By using the last user's ID

• By using a hardcoded value

• By using the first user's ID

• By using a random ID

What command is used to execute the seeder script for importing data?

• node index.js

• npm start

• node server.js

• npm run data import

What does the '-D' flag indicate when running the seeder script?

• To import data

• To destroy data

• To view data

• To update data

What is the purpose of adding NPM scripts for the seeder?

• To improve performance

• To enhance security

• To simplify running the seeder script

• To automate server deployment

What should you be cautious about when using the seeder script during development?

• It may cause syntax errors

• It can increase memory usage

• It could overwrite existing data

• It might slow down the server

What is the result of running 'npm run data destroy'?

• It updates existing data

• It imports new data

• It views current data

• It deletes all data
