redirect?

[Vue Router warn]: Detected a possibly infinite redirection in a navigation guard when going from "/dashboard" to "/auth/login". Aborting to avoid a Stack Overflow. Are you always returning a new location within a navigation guard? That would lead to this error. Only return when redirecting or aborting, that should fix this. This might break in production if not fixed.

Hi @Cordobes. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- You're encountering a common issue with Nuxt route middleware where you have an infinite redirection loop. This happens when your navigation guard keeps redirecting to new locations without a proper stopping condition. Based on the error message, your middleware is likely redirecting between "/dashboard" and "/auth/login" in an infinite loop. Here are some solutions to fix this issue: 1. Only return when redirecting The most common cause is returning a new location even when you should just continue the navigation. In your middleware:

export default defineNuxtRouteMiddleware((to, from) => {
  // If authenticated and trying to access login page
  if (isAuthenticated && to.path === '/auth/login') {
    return navigateTo('/dashboard');
  }
  
  // If not authenticated and trying to access protected routes
  if (!isAuthenticated && to.path !== '/auth/login') {
    return navigateTo('/auth/login');
  }
  
  // Important: return nothing (undefined) to continue normal navigation
  // Don't return navigateTo(to.fullPath) here!
})

export default defineNuxtRouteMiddleware((to, from) => {
  // If authenticated and trying to access login page
  if (isAuthenticated && to.path === '/auth/login') {
    return navigateTo('/dashboard');
  }
  
  // If not authenticated and trying to access protected routes
  if (!isAuthenticated && to.path !== '/auth/login') {
    return navigateTo('/auth/login');
  }
  
  // Important: return nothing (undefined) to continue normal navigation
  // Don't return navigateTo(to.fullPath) here!
})

2. Check for path equality Make sure you're not redirecting to the same path:

if (from.path !== to.path) {
  // Only redirect if paths are different
  return navigateTo('/auth/login');
}

if (from.path !== to.path) {
  // Only redirect if paths are different
  return navigateTo('/auth/login');
}

3. Use replace option Using the replace: true option can help in some cases:

return navigateTo('/auth/login', { replace: true });

return navigateTo('/auth/login', { replace: true });

4. Common mistake to avoid A common mistake is returning navigateTo(to.fullPath) when authenticated, which creates an infinite loop. Instead, return nothing to continue normal navigation:

// WRONG - causes infinite loop
if (userStore.authenticated) {
  return navigateTo(to.fullPath);
}

// CORRECT - just continue normal navigation
if (userStore.authenticated) {
  return; // or don't return anything
}

// WRONG - causes infinite loop
if (userStore.authenticated) {
  return navigateTo(to.fullPath);
}

// CORRECT - just continue normal navigation
if (userStore.authenticated) {
  return; // or don't return anything
}

This pattern is mentioned in several Stack Overflow posts about this exact issue, such as Nuxt 3 middleware from and to routes are always the same and Nuxt 3 middleware infinite navigation guard. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how i can redirect in vue

Let me check the knowledge base for you again. One moment! :books: ---------------------- In Nuxt, there are several ways to handle redirects. Based on our previous conversation about infinite redirection loops, here are the proper ways to implement redirects in Nuxt: Using Route Middleware The most common approach is using defineNuxtRouteMiddleware with the navigateTo helper:

export default defineNuxtRouteMiddleware((to, from) => {
  // Redirect logic here
  if (someCondition) {
    return navigateTo('/target-path');
  }
  
  // Return nothing to continue normal navigation
})

export default defineNuxtRouteMiddleware((to, from) => {
  // Redirect logic here
  if (someCondition) {
    return navigateTo('/target-path');
  }
  
  // Return nothing to continue normal navigation
})

In Page Components You can redirect from within a component using the navigateTo helper:

<script setup>
const { user, clear: clearSession } = useUserSession()

async function logout() {
  await clearSession()
  await navigateTo('/login')
}
</script>

<script setup>
const { user, clear: clearSession } = useUserSession()

async function logout() {
  await clearSession()
  await navigateTo('/login')
}
</script>

Nuxt docs on Sessions and Authentication show this pattern. Using Page Meta For static redirects, you can use definePageMeta with the redirect property:

definePageMeta({
  redirect: '/new-path'
})

definePageMeta({
  redirect: '/new-path'
})

Nuxt docs on definePageMeta explain this approach. Important Tips to Avoid Infinite Loops 1. Never return navigateTo(to.fullPath) in middleware when checking authentication - this causes infinite loops 2. Only return a redirect when necessary, otherwise return nothing to continue normal navigation 3. Use { replace: true } with navigateTo to replace the current history entry instead of adding a new one Remember that when using middleware, you should only return a navigation action when you want to redirect, and return nothing (or don't return at all) when you want to continue normal navigation. This approach will help you avoid the infinite redirection error we discussed previously. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
