Authentication
Authenticate your user thanks to the PKCE Oauth protocol that enables secure exchange of refresh and access tokens between an application and the authorization server
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. Alternatively, you can enable the redirect only for certain routes using the include redirect option.
Authentication -> Providers.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.
Authentication -> URL Configuration -> Redirect URLs.<script setup lang="ts">
const user = useSupabaseUser()
watch(user, () => {
if (user.value) {
// Redirect to protected page
return navigateTo('/')
}
}, { immediate: true })
</script>
<template>
<div>Waiting for login...</div>
</template>
Redirect path
You can easily handle redirection to the initial requested route after login.
cookieRedirect option of the redirectOptions to allow cookie storage and take benefit of this feature.<script setup lang="ts">
const user = useSupabaseUser()
// Get redirect path from cookies
const cookieName = useRuntimeConfig().public.supabase.cookieName
const redirectPath = useCookie(`${cookieName}-redirect-path`).value
watch(user, () => {
if (user.value) {
// Clear cookie
useCookie(`${cookieName}-redirect-path`).value = null
// Redirect to path
return navigateTo(redirectPath || '/');
}
}, { immediate: true })
</script>
