Authentication

With the default options, the module requires a log-in page and a confirm page to handle the PKCE authorization code flow. If you want to understand how it works under the hood, you can read this section.

All you need to do is to create a login.vue and confirm.vue page in the pages folder.

Log-in page - /login

Each time a user is trying to access a page that needs authentication, he will automatically be redirected to the configured log in page. If you want to allow access to "public" page, you just need to add them in the exclude redirect option.

The log-in page initiates the log-in method(s) you choose from the available authorization methods provided by Supabase, it could looks like:

<script setup lang="ts">
const supabase = useSupabaseClient()
const email = ref('')
const signInWithOtp = async () => {
  const { error } = await supabase.auth.signInWithOtp({
    email: email.value,
    options: {
      emailRedirectTo: 'http://localhost:3000/confirm',
    }
  })
  if (error) console.log(error)
}
</script>
<template>
  <div>
    <button @click="signInWithOtp">
      Sign In with E-Mail
    </button>
    <input
      v-model="email"
      type="email"
    />
  </div>
</template>

Once the authorization flow is triggered using the auth wrapper of the useSupabaseClient composable, the session management is handled automatically and the user will be redirected to the page you specify in the redirect option (/confirm by default).

Confirm page - /confirm

The confirmation page receives the supabase callback. From there you can check the user value and redirect to the appropriate page.

<script setup lang="ts">
const user = useSupabaseUser()
watch(user, () => {
  if (user.value) {
    return navigateTo('/')
  }
}, { immediate: true })
</script>
<template>
  <div>Waiting for login...</div>
</template>
