Question

I’m working with Next.js and facing an issue where middleware is not being triggered on subsequent navigations from a client-side route. Specifically, I’m using router.push in a React component with use client, but it seems that the middleware only performs its check on the first request and does not re-evaluate subsequent navigations. (NextJS 14)

Problem :
I have the following middleware configuration :

//app/user/signIn/page.js

'use client'

import { useState } from 'react'
import { signIn } from 'next-auth/react'
import { useRouter } from 'next/navigation'
import Link from 'next/link';

export default function SignIn() {
  const [email, setEmail] = useState('')
  const [password, setPassword] = useState('')
  const [error, setError] = useState(null)
  const router = useRouter()

  const handleSubmit = async (e) => {
    e.preventDefault()
    try {
      const result = await signIn('credentials', {
        redirect: false,
        email,
        password,
      })

      if (result.error) {
        setError('email or password is incorrect.')
      } else {
        router.push('/user/profile')
      }
    } catch (error) {
      console.log('error', error)
      setError('An unexpected error occurred. Please try again later.')
    }
  }

  return (
    <>
      <div className='text-center'>
        <Link href="/user/profile" className="block mb-2">[Profile Menu]</Link>

              type="email"
              value={email}
              onChange={(e) => setEmail(e.target.value)}
              required
              className="w-full border border-gray-300 px-3 py-2 rounded"
            />

  },
}

const handler = NextAuth(authOptions)

export { handler as GET, handler as POST }

Issue:

When I navigate to /user/profile after signing in, the middleware performs the redirection as expected if there is no token.
However, when I navigate to /user/profile again from the client-side using router.push, the middleware does not re-check or perform the redirection again.

Question:

Is this behavior expected with Next.js middleware? Why does the middleware only trigger on the first request and not on subsequent navigations from the client-side? How can I ensure that the middleware runs and performs checks on every request, even those triggered by router.push from a client-side component?

Additional Information:

I’m using Next.js with NextAuth for authentication.
My goal is to make sure that every time a user tries to access /user/profile, the middleware checks for a token and redirects to the sign-in page if the token is missing.
