[solved] beforeEnter in Nuxt3

Hello everyone! Having a difficult time migrating our big-big project from Nuxt2 to Nuxt3, heh. In one of my pages I have the route guard "beforeRouteEnter", which I cannot find in setup hooks (only onBeforeRouteLeave and onBeforeRouteUpdated). I googled this, but did not find any actual solution for this. In vue-router "beforeEnter" now is set in routes definition file directly, not on the page. Any workarounds on this in Nuxt3? Thank you!

Hi @Wander. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In Nuxt 3, the concept of route middleware has been introduced which simplifies the implementation of navigation guards and provides a better developer experience. This can be used as a workaround for the beforeEnter route guard. There are three kinds of route middleware: 1. Anonymous (or inline) route middleware, which are defined directly in the pages where they are used. 2. Named route middleware, which are placed in the middleware/ directory and will be automatically loaded via asynchronous import when used on a page. 3. Global route middleware, which are placed in the middleware/ directory (with a .global suffix) and will be automatically run on every route change. Here is an example of a middleware protecting the /dashboard page:

export default defineNuxtRouteMiddleware((to, from) => {
  // isAuthenticated() is an example method verifying if a user is authenticated
  if (isAuthenticated() === false) {
    return navigateTo('/login')
  }
})

export default defineNuxtRouteMiddleware((to, from) => {
  // isAuthenticated() is an example method verifying if a user is authenticated
  if (isAuthenticated() === false) {
    return navigateTo('/login')
  }
})

This middleware will be run before navigating to the /dashboard page, similar to how beforeEnter would work in Vue Router. You can read more about this in the Nuxt documentation (https://nuxt.com/docs/guide/directory-structure/middleware) and the migration guide (https://nuxt.com/docs/migration/plugins-and-middleware). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

That's not a solution, since it works in both cases - leaving a route and entering. I need entering only. Correct me if I'm wrong

Pretty sure route middleware behave as "beforeRouteEnter" by default, no? https://nuxt.com/docs/guide/directory-structure/middleware#usage ie "from" is the current route, "to" is the next one. If you want to cancel navigation before going to "next" you could abort nav

Nuxt provides middleware to run code before navigating to a particular route.

You're right. I had another problem that caused doubling of the logs when leaving the route. Thanks!
