Vue Router Basics: Navigation and Dynamic Routes Quiz Quiz

Explore essential Vue Router concepts with this quiz focused on navigation methods and dynamic route configuration. Perfect for learners aiming to strengthen their understanding of Vue Router’s navigation guards, dynamic parameters, and related routing features.

1. Programmatic Navigation in Vue Router

   Which method allows you to navigate programmatically to the '/profile' route in a Vue Router setup?

   1. this.routerNavigate('/profile')
   2. this.$router.push('/profile')
   3. this.$route.go('/profile')
   4. this.navigateTo('/profile')

   Explanation: The correct method for programmatic navigation in Vue Router is 'this.$router.push('/profile')', which updates the current route. 'this.routerNavigate' and 'this.navigateTo' are not valid Vue Router methods, so they would fail to change the route. 'this.$route.go' is incorrect because '$route' refers to the current route object and does not provide navigation methods like 'go' in this context. Only 'this.$router.push' properly performs navigation within a component.

2. Dynamic Route Matching

   Given a route defined as '/user/:id', which URL would match this dynamic route and pass a parameter?

   1. /user/42
   2. /user?id=42
   3. /users/42
   4. /user/id/42

   Explanation: The URL '/user/42' matches the pattern '/user/:id', with '42' as the dynamic parameter for 'id'. '/user?id=42' uses a query string instead of a route parameter, so it does not match the route definition. '/users/42' has a typo in the path segment ('users' instead of 'user'), and '/user/id/42' introduces an extra path segment, which also breaks the match. Only '/user/42' follows the defined dynamic route structure.

3. Passing Route Parameters as Props

   Which prop setting lets a component automatically receive route params as props in a Vue Router route definition?

   1. params: props
   2. props: true
   3. enableProps: true
   4. props: params

   Explanation: Setting 'props: true' in a route definition ensures that route parameters are passed as component props. 'params: props' and 'props: params' are invalid and do not exist in the Vue Router API, so they will not pass parameters as props. 'enableProps: true' is not recognized by the router and will have no effect. Therefore, 'props: true' is the correct and only valid way among the options.

4. Navigation Guards and Route Protection

   Which navigation guard can be used globally to check user authentication before allowing route access in Vue Router?

   1. beforeRouteEnter
   2. router.beforeEach
   3. beforeRouteGuard
   4. routerNavigation

   Explanation: 'router.beforeEach' can be registered globally to check authentication or other conditions before every route navigation. 'beforeRouteEnter' is a route-specific guard that works at the component level, not globally. 'routerNavigation' and 'beforeRouteGuard' are not valid Vue Router navigation guard names, and using them would result in errors or be ignored. Only 'router.beforeEach' provides global guarding functionality.

5. Navigation with Named Routes

   Which code statement is used to navigate to a route named 'dashboard' and pass a dynamic 'section' parameter equal to 'reports'?

   1. this.$router.push('dashboard?section=reports')
   2. this.$router.push({ name: 'dashboard', params: { section: 'reports' } })
   3. this.$route.push('dashboard', { section: 'reports' })
   4. this.navigateTo('/dashboard/reports')

   Explanation: The code 'this.$router.push({ name: 'dashboard', params: { section: 'reports' } })' uses the named route with params, which is the correct Vue Router way to navigate and pass dynamic values. 'this.$router.push('dashboard?section=reports')' incorrectly uses query syntax with a route name, which only works for paths, not named routes. 'this.navigateTo' is not a Vue Router method, so it is invalid. 'this.$route.push' does not exist, as '$route' is a route object, not a router instance; navigation functions are methods of '$router'.
