💡 Hint

Common Mistakes

Importing from 'next/router' which is for the old pages router.

In Next.js App Router, useRouter is imported from next/navigation to access routing features.

Complete the code to create a Remix loader function that fetches data.

NextJS

export async function loader() {
  const data = await fetch('/api/data').then(res => res.json());
  return [1]({ data });
}

💡 Hint

Common Mistakes

Using 'response' or 'send' which are not Remix loader helpers.

Remix uses the json helper to return JSON responses from loaders.

Fix the error in the Nuxt 3 page script setup by completing the import statement.

NextJS

<script setup>
import { [1] } from 'vue';
const count = ref(0);
</script>

💡 Hint

Common Mistakes

Importing 'reactive' instead of 'ref' for simple reactive values.

In Nuxt 3, ref is imported from Vue to create reactive references.

4fill in blank

Fill both blanks to create a Next.js server action that updates data and redirects.

NextJS

export const updateData = async (formData) => {
  await updateDatabase(formData);
  return [1]('/success');
};

export default function Page() {
  const router = useRouter();
  const handleSubmit = async (data) => {
    await updateData(data);
    router.[2]('/success');
  };
}

Bpush

Dnavigate

💡 Hint

Common Mistakes

Using 'navigate' which is not a Next.js router method.

Next.js server actions use redirect to send redirects from the server. On the client, router.push navigates to a new page.

5fill in blank

hard

Fill all three blanks to create a Nuxt 3 async data fetch with error handling.

NextJS

<script setup>
const { data, error } = await useAsyncData('posts', () => fetch('/api/posts').then(res => res.[1]()));

if (error.value) {
  console.error('Failed to load posts:', error.value.[2]);
}

const posts = data.value || [3];
</script>

Dtext

💡 Hint

Common Mistakes

Using 'text' instead of 'json' for parsing response.

To fetch JSON data, use res.json(). Errors have a message property. If no data, use an empty array [] as fallback.

Practice

1. Which JavaScript framework does Nuxt.js primarily use?

easy

A. Vue.js

B. React

C. Angular

D. Svelte

Solution

1. Step 1: Identify Nuxt.js framework

   Nuxt.js is a framework built on top of Vue.js to help build server-rendered Vue applications.

2. Step 2: Compare with other frameworks

   Next.js and Remix use React, while Nuxt.js uses Vue.js.

3. Final Answer:

   Vue.js -> Option A

4. Quick Check:

   Nuxt.js = Vue.js [OK]

Hint: Nuxt always pairs with Vue.js, not React or others [OK]

Common Mistakes:

• Confusing Nuxt.js with Next.js and choosing React
• Thinking Nuxt uses Angular or Svelte
• Assuming all three use the same framework

2. Which of the following is the correct way to create a new Next.js page component?

easy

A. const Page = () => { Hello } export default Page

B. function Page() { return Hello } export Page

C. export default function Page() { return Hello }

D. export function Page() { return Hello }

Solution

1. Step 1: Check correct export syntax

   Next.js pages require a default export of a React component function.

2. Step 2: Validate component syntax

   export default function Page() { return
   Hello } correctly exports a function component as default returning JSX.

3. Final Answer:

   export default function Page() { return <div>Hello</div> } -> Option C

4. Quick Check:

   Default export + function component = export default function Page() { return
   Hello
   } [OK]

Hint: Next.js pages must default export a React component [OK]

Common Mistakes:

• Forgetting default keyword in export
• Missing return statement in arrow function
• Using named export instead of default

3. Given the following Remix loader function, what will be the JSON response?

export async function loader() {
  return { message: 'Hello from Remix' };
}

medium

A. Response with JSON body { message: 'Hello from Remix' }

B. { message: 'Hello from Remix' }

C. Undefined

D. SyntaxError

Solution

1. Step 1: Understand Remix loader return

   Remix loader functions must return a Response or data wrapped by Remix to send JSON.

2. Step 2: Recognize automatic JSON response

   Returning a plain object causes Remix to send a JSON response with that object as body.

3. Final Answer:

   Response with JSON body { message: 'Hello from Remix' } -> Option A

4. Quick Check:

   Remix loader returns JSON response = Response with JSON body { message: 'Hello from Remix' } [OK]

Hint: Remix loader returns data as JSON response automatically [OK]

Common Mistakes:

• Assuming plain object is returned directly to client
• Expecting undefined or error from loader
• Confusing Remix loader with Next.js getServerSideProps

4. Identify the error in this Nuxt page component code:

<script setup>
const message = 'Hello Nuxt'
</script>

<template>
  <h1>{{ msg }}</h1>
</template>

medium

A. Missing export default statement

B. Variable name mismatch: 'message' vs 'msg'

C. Incorrect script tag, should be <script> only

D. Template syntax error, must use v-text

Solution

1. Step 1: Check variable declaration

   The script defines a variable named 'message'.

2. Step 2: Check template usage

   The template tries to display 'msg', which is undefined.

3. Final Answer:

   Variable name mismatch: 'message' vs 'msg' -> Option B

4. Quick Check:

   Variable names must match in script and template [OK]

Hint: Match variable names exactly between script and template [OK]

Common Mistakes:

• Using different variable names in template and script
• Forgetting to use
• Thinking export default is required with

5. You want to build a server-rendered app with React and prefer file-based routing plus API routes. Which framework fits best?

hard

A. Angular Universal

B. Remix

C. Nuxt.js

D. Next.js

Solution

1. Step 1: Identify framework features

   Next.js supports React, file-based routing, and API routes out of the box.

2. Step 2: Compare with other options

   Nuxt.js uses Vue, Remix uses React but does not have built-in API routes, Angular Universal is Angular-based.

3. Final Answer:

   Next.js -> Option D

4. Quick Check:

   React + file routing + API routes = Next.js [OK]

Hint: Next.js = React + file routing + API routes [OK]

Common Mistakes:

• Choosing Nuxt.js for React apps
• Assuming Remix has built-in API routes
• Confusing Angular Universal with React frameworks
