💡 Hint

Common Mistakes

Using 'devtools' instead of 'productionTip'

Trying to set 'isProduction' which is not a Vue config property

Setting app.config.productionTip = false disables the production tip message in the console.

2fill in blank

medium

Complete the code to import the Vue production build for optimization.

Vue

import { createApp } from 'vue/dist/vue.[1].js'
const app = createApp(App)
app.mount('#app')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'development' build which is not optimized

Using 'runtime' which is incomplete for production

Importing from 'vue/dist/vue.production.js' loads the optimized production build.

3fill in blank

hard

Fix the error in the Vue CLI build command for production.

Vue

vue-cli-service build --[1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'dev' or 'prod' which are invalid flags

Omitting 'mode' keyword

The correct flag to specify production mode is --mode production.

4fill in blank

hard

Fill both blanks to configure Vue to remove devtools and enable performance tracking in production.

Vue

app.config.[1] = false
app.config.[2] = true

Drag options to blanks, or click blank then click option'

Adevtools

CproductionTip

Dsilent

💡 Hint

Common Mistakes

Confusing 'productionTip' with 'devtools'

Setting 'silent' which controls warnings, not devtools

Disabling devtools and enabling performance helps optimize production builds.

5fill in blank

hard

Fill all three blanks to create a Vue 3 production build script with environment variable and minification.

Vue

export default {
  mode: '[1]',
  build: {
    [2]: true,
    [3]: true
  }
}

Drag options to blanks, or click blank then click option'

Cminify

Dsourcemap

💡 Hint

Common Mistakes

Using 'development' mode for production build

Confusing 'minify' with 'sourcemap' settings

Setting mode to 'production' enables production optimizations. minify compresses code, and sourcemap generates source maps for debugging.
