The middleware property

Set the middleware for a specific page of the application.

Type: String or Array or Function
- Items: String or Function

Named middleware

You can create named middleware by creating a file inside the middleware/ directory, the file name will be the middleware name.

middleware/authenticated.js

export default function ({ store, redirect }) {
  // If the user is not authenticated
  if (!store.state.authenticated) {
    return redirect('/login')
  }
}

pages/secret.vue

<template>
  <h1>Secret page</h1>
</template>

<script>
  export default {
    middleware: 'authenticated'
  }
</script>

Anonymous middleware

If you need to use a middleware only for a specific page, you can directly use a function for it (or an array of functions):

pages/secret.vue

<template>
  <h1>Secret page</h1>
</template>

<script>
  export default {
    middleware({ store, redirect }) {
      // If the user is not authenticated
      if (!store.state.authenticated) {
        return redirect('/login')
      }
    }
  }
</script>
