Build optimization for production in Vue - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main goal of build optimization in Vue production?

To make the app load faster and run smoothly by reducing file sizes and improving performance.

How does code splitting help in Vue production builds?

It breaks the app into smaller pieces so the browser loads only what is needed at first, speeding up initial load time.

intermediate

What role does tree shaking play in Vue build optimization?

Tree shaking removes unused code from libraries and your app, making the final bundle smaller.

beginner

Why is minification important in production builds?

Minification shrinks code by removing spaces and shortening names, which reduces file size and speeds up loading.

intermediate

What is lazy loading in Vue and how does it improve production performance?

Lazy loading delays loading parts of the app until they are needed, reducing initial load time and saving bandwidth.

Which technique splits your Vue app into smaller chunks to load on demand?

A Hot module replacement

B Minification

C Tree shaking

D Code splitting

Code splitting breaks the app into smaller files that load only when needed.

What does tree shaking do in a Vue production build?

A Removes unused code

B Adds comments for debugging

C Splits code into chunks

D Delays loading components

Tree shaking removes code that is not used to reduce bundle size.

Why is minification used in production builds?

A To reduce file size by removing spaces and shortening names

B To split code into modules

C To add extra features

D To make code easier to read

Minification reduces file size by removing unnecessary characters.

What is lazy loading in Vue?

A Loading all components at once

Which tool is commonly used to optimize Vue production builds?

A Vue Devtools

B Vue CLI with webpack

C Vue Router

D Vuex

Vue CLI uses webpack to bundle and optimize production builds.
