Why production setup differs from development in Node.js - Quick Recap

Recall & Review

beginner

Why do we use different setups for development and production in Node.js?

Development setup focuses on ease of coding and debugging, while production setup focuses on performance, security, and stability for real users.

What is one key difference in error handling between development and production?

In development, detailed error messages help debugging. In production, errors are logged quietly to avoid exposing sensitive info to users.

How does performance optimization differ between development and production?

Production uses optimizations like caching and minification to speed up apps, while development prioritizes fast reloads and easy changes.

intermediate

Why is environment configuration important in production?

Production uses environment variables to securely manage secrets and settings, avoiding hard-coded values that can cause security risks.

intermediate

What role does logging play in production compared to development?

Production logging focuses on important events and errors for monitoring, while development logs more details to help developers understand app behavior.

Which is a main goal of production setup in Node.js?

A Use unminified code for readability

B Show detailed error messages to users

C Enable fast code changes and reloads

D Maximize security and performance

Production setup aims to keep the app secure and fast for users.

Why do we avoid showing detailed errors in production?

A To slow down the app

B Because errors never happen in production

C To prevent exposing sensitive information

D To make debugging easier for users

Detailed errors can reveal secrets or weaknesses to attackers.

What is a common practice for managing secrets in production?

A Hard-coding them in source code

B Using environment variables

C Writing them in public logs

D Ignoring them

Environment variables keep secrets out of code and allow easy changes.

Which tool is often used in production to improve performance?

A Code minification

B Verbose logging

C Live reload

D Debug mode

Minification reduces file size, speeding up loading times.

In development, what is prioritized over performance?

A Fast code changes and debugging

B Error hiding

C Security

D Caching

Developers need quick feedback and easy debugging.
