💡 Hint

Common Mistakes

Using .js or .jsx instead of .vue

Using .astro extension for Vue components

Vue components have the .vue file extension, so you import them with that extension.

💡 Hint

Common Mistakes

Using Vue directives like v-if inside Astro files

Using client:load instead of client:only for Vue components

Astro uses client:only directive to render Vue components on the client side only.

3fill in blank

Fix the error in the Vue component usage by completing the client directive.

Astro

<MyComponent [1] />

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

💡 Hint

Common Mistakes

Using client:mount which is not a valid Astro directive

Using client:only without import

client:load tells Astro to load the Vue component as soon as the page loads, fixing errors related to missing client hydration.

4fill in blank

hard

Fill both blanks to correctly import and use a Vue component with client-side rendering in Astro.

Astro

import [1] from './components/Widget.vue';

<[2] client:only="vue" />

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

💡 Hint

Common Mistakes

Using different names for import and usage

Forgetting client:only directive

The imported component name must match the tag used in the Astro file to render it properly.

5fill in blank

hard

Fill all three blanks to pass a prop named 'title' with value 'Hello' to a Vue component in Astro.

Astro

import Card from './components/Card.vue';

<Card [1]=[2] [3] />

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

Atitle

B"Hello"

Cclient:only="vue"

Dclient:load

Attempts:

💡 Hint

Common Mistakes

Passing props without quotes

Forgetting client:only directive

Using client:load instead of client:only

Props are passed as attributes like title="Hello". The component must be hydrated on the client with client:only="vue".

Practice

1. What is the main reason to use Vue components inside an Astro project?

easy

A. To replace Astro's server-side rendering completely

B. To style Astro pages using Vue's CSS features

C. To write backend API routes in Vue syntax

D. To add interactive parts to otherwise static Astro pages

Solution

1. Step 1: Understand Astro's default behavior

   Astro builds mostly static pages by default, which are fast but not interactive.

2. Step 2: Role of Vue components in Astro

   Vue components add interactivity, like buttons or forms, inside these static pages.

3. Final Answer:

   To add interactive parts to otherwise static Astro pages -> Option D

4. Quick Check:

   Vue components = interactivity in Astro [OK]

Hint: Vue in Astro = add interactivity, not replace rendering [OK]

Common Mistakes:

• Thinking Vue replaces Astro's rendering
• Confusing Vue with backend API code
• Assuming Vue handles styling only

2. Which is the correct way to import and use a Vue component named MyButton.vue inside an Astro file?

easy

A. import MyButton from './MyButton.vue';

B. import MyButton from './MyButton.vue';

C. import MyButton from './MyButton.vue';

D. import MyButton from './MyButton.vue';

Solution

1. Step 1: Import Vue component correctly

   Use import MyButton from './MyButton.vue'; to import the component.

2. Step 2: Use client directive for loading

   client:load tells Astro to load the Vue component on page load, enabling interactivity.

3. Final Answer:

   import MyButton from './MyButton.vue'; <MyButton client:load /> -> Option B

4. Quick Check:

   Import + client:load = correct usage [OK]

Hint: Always add client directive to activate Vue in Astro [OK]

Common Mistakes:

• Omitting client directive causes no interactivity
• Using client:only without specifying framework
• Using client:idle without understanding lazy load

3. Given this Astro code snippet, what will be rendered on the page?

---
import Counter from './Counter.vue';
---

Assuming Counter.vue shows a button that increments a number on click.

medium

A. A button showing a number that increments when clicked

B. A static button with no click functionality

C. An error because client directive is missing

D. Nothing renders because Vue is not supported

Solution

1. Step 1: Understand client:load directive effect

   The client:load directive loads the Vue component on page load, enabling interactivity.

2. Step 2: Behavior of Counter.vue

   Counter.vue is a Vue component that shows a button with a number that increments on click, so it will work interactively.

3. Final Answer:

   A button showing a number that increments when clicked -> Option A

4. Quick Check:

   client:load + Vue component = interactive output [OK]

Hint: client:load activates Vue interactivity on page load [OK]

Common Mistakes:

• Assuming static output without interactivity
• Thinking client directive is optional
• Believing Vue components don't render in Astro

4. What is wrong with this Astro code using a Vue component?

---
import MyWidget from './MyWidget.vue';
---

Why does the component not behave interactively in the browser?

medium

A. Missing client directive to load Vue component on client

B. Incorrect import path for the Vue component

C. Vue components cannot be used in Astro files

D. The component file must be named with .astro extension

Solution

1. Step 1: Check import correctness

   The import path looks correct assuming file exists, so no error here.

2. Step 2: Identify missing client directive

   Without a client directive like client:load, Vue components render as static HTML with no interactivity.

3. Final Answer:

   Missing client directive to load Vue component on client -> Option A

4. Quick Check:

   Vue needs client directive for interactivity [OK]

Hint: Always add client:load or similar to activate Vue [OK]

Common Mistakes:

• Forgetting client directive disables interactivity
• Assuming import path error without checking
• Thinking Vue components need .astro extension

5. You want to optimize your Astro page by loading a Vue component only when it becomes visible on screen. Which client directive should you use?

import LazyWidget from './LazyWidget.vue';

Choose the correct usage:

hard

A. <LazyWidget client:load />

B. <LazyWidget client:idle />

C. <LazyWidget client:visible />

D. <LazyWidget client:only='vue' />

Solution

1. Step 1: Understand client directives for lazy loading

   client:visible loads the component only when it scrolls into view, optimizing performance.

2. Step 2: Compare other directives

   client:idle loads when browser is idle, client:load loads immediately, and client:only='vue' loads only Vue but not lazily.

3. Final Answer:

   <LazyWidget client:visible /> -> Option C

4. Quick Check:

   client:visible = load on visibility [OK]

Hint: Use client:visible to load Vue component on scroll into view [OK]

Common Mistakes:

• Using client:load loads immediately, not lazily
• Confusing client:idle with visibility trigger
• Using client:only without lazy loading effect
