Common Mistakes

Not registering RouterView in components.

Using wrong casing in template or import.

The template uses router-view tag, the script imports RouterView, and registers it in components for use.

Practice

1. What is the main purpose of RouterView in a Vue application?

easy

A. To define routes and their components

B. To display the component that matches the current route URL

C. To style the navigation bar

D. To fetch data from an API

Solution

1. Step 1: Understand RouterView role

   RouterView is a placeholder that Vue Router uses to show the component for the current URL.

2. Step 2: Differentiate from other router parts

   Defining routes is done in the router config, not in RouterView. Styling and data fetching are unrelated.

3. Final Answer:

   To display the component that matches the current route URL -> Option B

4. Quick Check:

   RouterView shows current page = A [OK]

Hint: RouterView shows the page for the URL [OK]

Common Mistakes:

• Confusing RouterView with route definitions
• Thinking RouterView styles navigation
• Assuming RouterView fetches data

2. Which of the following is the correct way to use RouterView in a Vue component template?

easy

A.

B.

C.

D.

Solution

1. Step 1: Recall Vue Router syntax

   The official tag for rendering matched components is <router-view> in kebab-case.

2. Step 2: Check case sensitivity

   Vue components and tags are case-sensitive. RouterView (PascalCase) is not valid in templates, nor is routerView or router_view.

3. Final Answer:

   <router-view></router-view> -> Option C

4. Quick Check:

   Use kebab-case tag [OK]

Hint: Use lowercase with dash: [OK]

Common Mistakes:

• Using PascalCase <RouterView> in template
• Using camelCase or underscores in tag name
• Forgetting closing tag

3. Given this Vue Router setup and component usage, what will be rendered inside <router-view> when the URL is /about?

const routes = [
  { path: '/', component: Home },
  { path: '/about', component: About }
];

// In App.vue template:
// <router-view></router-view>

medium

A. The About component content

B. The Home component content

C. Nothing, because no component is matched

D. An error because routes are not defined properly

Solution

1. Step 1: Match URL to route

   The URL /about matches the route with path /about which uses the About component.

2. Step 2: Understand RouterView rendering

   <router-view> renders the component for the matched route, so it will show About's content.

3. Final Answer:

   The About component content -> Option A

4. Quick Check:

   URL /about shows About component [OK]

Hint: RouterView shows component for current URL [OK]

Common Mistakes:

• Assuming root component always shows
• Thinking RouterView shows nothing if not root
• Believing routes need special syntax to match

4. What is wrong with this Vue component template using RouterView?

<template>
  <div>
    <RouterView />
  </div>
</template>

medium

A. The RouterView tag should be lowercase as router-view

B. RouterView cannot be self-closing

C. RouterView must be inside a <router> tag

D. RouterView requires a slot to render content

Solution

1. Step 1: Check tag casing rules

   In Vue templates, the router-view component must be written in kebab-case, all lowercase with a dash.

2. Step 2: Validate other options

   Self-closing is allowed in Vue 3. There is no <router> tag, and router-view does not require slots to render matched components.

3. Final Answer:

   The <RouterView> tag should be lowercase as <router-view> -> Option A

4. Quick Check:

   Use lowercase tag [OK]

Hint: Use lowercase , not PascalCase [OK]

Common Mistakes:

• Writing <RouterView> instead of
• Thinking self-closing is invalid
• Expecting a <router> wrapper tag

5. You want to create a nested route in Vue where /dashboard shows a Dashboard component and inside it, /dashboard/settings shows a Settings component. How should you use RouterView to render the nested Settings component inside Dashboard?

hard

A. Place <router-view> only in the main App.vue template

B. Nest <router-view> inside <router-link> in Dashboard

C. Use two <router-view> tags side by side in App.vue

D. Place <router-view> inside the Dashboard component template where Settings should appear

Solution

1. Step 1: Understand nested routes rendering

   Nested routes render their child components inside the parent's RouterView. So Dashboard must have a <router-view> to show Settings.

2. Step 2: Check other options

   Placing RouterView only in App.vue won't render nested children inside Dashboard. Two side-by-side RouterView tags or nesting inside router-link are incorrect usage.

3. Final Answer:

   Place <router-view> inside the Dashboard component template where Settings should appear -> Option D

4. Quick Check:

   Nested routes need RouterView inside parent [OK]

Hint: Put inside parent component for nested routes [OK]

Common Mistakes:

• Not placing RouterView inside parent component
• Trying to render nested routes only in App.vue
• Misusing router-link as container
