Practice - 5 Tasks

1fill in blank

easy

Complete the code to load the component only on the client after the page loads.

Astro

<MyComponent [1] />

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

💡 Hint

Common Mistakes

Using client:idle which loads when the browser is idle, not immediately after load.

Using client:visible which loads when the component is visible in viewport.

The client:load directive tells Astro to load the component only on the client side after the page has loaded.

Complete the code to import and use a component with client:load directive.

Astro

import MyComponent from './MyComponent.astro';

export default function Page() {
  return <MyComponent [1] />;
}

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

💡 Hint

Common Mistakes

Using client:only which loads only on client but immediately.

Using client:idle which waits for browser idle.

Using client:load on the component ensures it loads on the client after the page load.

3fill in blank

hard

Fix the error in the code to correctly use client:load directive on the component.

Astro

<MyComponent [1] />

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

💡 Hint

Common Mistakes

Replacing colon with dash or underscore.

Omitting the colon entirely.

The correct syntax uses a colon: client:load. Other forms are invalid.

4fill in blank

hard

Fill both blanks to create a component that loads on client after page load and passes a prop.

Astro

<MyComponent [1] title=[2] />

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

Aclient:load

B"Hello"

C"World"

Dclient:idle

💡 Hint

Common Mistakes

Using client:idle instead of client:load.

Passing unquoted strings as props.

Use client:load to load after page load and pass the string "Hello" as the title prop.

5fill in blank

hard

Fill all three blanks to create an object that loads components with client:load and filters names with length > 3.

Astro

const components = Object.fromEntries(
  names.filter(name => name.length > 3)
    .map([1] => [
      [2],
      <MyComponent [3] title={name} />
    ])
);

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

💡 Hint

Common Mistakes

Using client:idle instead of client:load.

Using different variable names inconsistently.

The object keys use name, the loop variable is name, and the directive is client:load.

Practice

1. What does the client:load directive do in Astro?

easy

A. It delays loading a component until the entire page has loaded.

B. It loads the component immediately during server rendering.

C. It prevents the component from ever loading on the client.

D. It loads the component only when it becomes visible on screen.

Solution

1. Step 1: Understand the purpose of client:load

   This directive delays the component's loading until after the full page load event.

2. Step 2: Compare with other loading strategies

   Unlike immediate or lazy loading on visibility, client:load waits for the whole page to finish loading.

3. Final Answer:

   It delays loading a component until the entire page has loaded. -> Option A

4. Quick Check:

   client:load delays loading = A [OK]

Hint: Remember: client:load waits for full page load before running [OK]

Common Mistakes:

• Confusing client:load with immediate loading
• Thinking it loads on scroll or visibility
• Assuming it prevents client loading entirely

2. Which is the correct self-closing syntax to use client:load on a component named MyWidget?

easy

A.

B.

C.

D.

Solution

1. Step 1: Recall Astro directive syntax

   Astro directives use colon syntax like client:load as an attribute on components.

2. Step 2: Check valid self-closing tag usage

   Using <MyWidget client:load /> is valid and concise for components without children.

3. Final Answer:

   <MyWidget client:load /> -> Option D

4. Quick Check:

   Correct directive syntax = A [OK]

Hint: Use colon syntax exactly: client:load [OK]

Common Mistakes:

• Replacing colon with camelCase or dash
• Omitting the colon
• Using incorrect closing tags

3. Given this Astro component usage:

<MyWidget client:load />

What will happen when the page loads?

medium

A. MyWidget renders immediately during server-side rendering.

B. MyWidget loads as soon as it scrolls into view.

C. MyWidget loads only after the entire page finishes loading in the browser.

D. MyWidget never loads on the client side.

Solution

1. Step 1: Understand client:load behavior

   The client:load directive delays loading the component until after the full page load event in the browser.

2. Step 2: Compare with other loading triggers

   It does not load immediately or on scroll, but waits for the page to fully load.

3. Final Answer:

   MyWidget loads only after the entire page finishes loading in the browser. -> Option C

4. Quick Check:

   client:load triggers after full page load = D [OK]

Hint: client:load waits for full page load before running component [OK]

Common Mistakes:

• Thinking it loads during server rendering
• Confusing with lazy loading on scroll
• Assuming it never loads on client

4. You wrote this code but the component loads immediately, not after page load:

<MyWidget client-load />

What is the error?

medium

A. You must import client:load from Astro first.

B. The directive should be client:load with a colon, not a dash.

C. The component must be wrapped in a <client:load> tag.

D. The component cannot be self-closing.

Solution

1. Step 1: Identify incorrect directive syntax

   The directive uses a dash client-load instead of the required colon client:load.

2. Step 2: Understand Astro directive rules

   Astro directives must use colon syntax exactly; dashes are invalid and ignored.

3. Final Answer:

   The directive should be client:load with a colon, not a dash. -> Option B

4. Quick Check:

   Correct directive syntax uses colon = C [OK]

Hint: Check for colon, not dash, in directive name [OK]

Common Mistakes:

• Using dash instead of colon in directive
• Thinking directives need imports
• Believing self-closing tags cause loading issues

5. You want to add a chat widget that should only load after the page fully loads to avoid slowing initial load. Which is the best way to do this in Astro?

hard

A. Use <ChatWidget client:load /> to delay loading until after page load.

B. Use <ChatWidget client:idle /> to load when browser is idle.

C. Use <ChatWidget client:visible /> to load when visible on screen.

D. Render <ChatWidget /> normally without directives.

Solution

1. Step 1: Identify the requirement

   The chat widget should load only after the full page load to keep initial load fast.

2. Step 2: Match directive to requirement

   client:load delays loading until after the page fully loads, fitting the need perfectly.

3. Step 3: Compare other options

   client:idle waits for browser idle, client:visible waits for scroll visibility, and no directive loads immediately.

4. Final Answer:

   Use <ChatWidget client:load /> to delay loading until after page load. -> Option A

5. Quick Check:

   Delay until full page load = client:load = B [OK]

Hint: Use client:load to delay widget until after full page load [OK]

Common Mistakes:

• Choosing client:idle or client:visible which load at different times
• Not using any directive causing immediate load
• Misunderstanding when client:load triggers
