Authentication

Learn how to authenticate users with the strapi module in your Nuxt 3 application.

This module exposes composables that are auto-imported by Nuxt 3.

useStrapiUser

Once logged in, you can access your user everywhere:

const user = useStrapiUser()

Learn how to protect your routes by writing your own auth middleware composable.

useStrapiToken

This composable is an helper to get the jwt token. It is used internally to get the strapi_jwt cookie.

const token = useStrapiToken()

useStrapiAuth

This composable exposes all the methods available in the Strapi Users & Permissions plugin.

On login, register, resetPassword and authenticateProvider methods, the user is populated through the fetchUser method.

login

Submit the user's identifier and password credentials for authentication. Sets user and token.

pages/login.vue
<script setup lang="ts">const { login } = useStrapiAuth()const router = useRouter()const onSubmit = async () => {  try {    await login({ identifier: '', password: '' })    router.push('/authenticated-page')  } catch (e) {}}</script>

Check out the Strapi Login documentation.

logout

Unset user and token.

<script setup lang="ts">const { logout } = useStrapiAuth()const router = useRouter()const onClick = () => {  logout()  router.push('/')}</script>

register

Creates a new user in the database with a default role as Authenticated.

Custom user fields, if added to the content type, e.g. phoneNumber, can be added to the payload as well.

pages/register.vue
<script setup lang="ts">const { register } = useStrapiAuth()const router = useRouter()const onSubmit = async () => {  try {    await register({ username: '', email: '', password: '', phoneNumber: '' })    router.push('/authenticated-page')  } catch (e) {}}</script>

Check out the Strapi Registration documentation.

forgotPassword

This action sends an email to a user with the link to your own reset password page. The link will be enriched with the url param code that is needed for the resetPassword.

pages/forgot.vue
<script setup lang="ts">const { forgotPassword } = useStrapiAuth()const router = useRouter()const onSubmit = async () => {  try {    await forgotPassword({ email: '' })    router.push('/')  } catch (e) {}}</script>

Check out the Strapi Forgot & Reset flow documentation.

resetPassword

This action will update the user password. Sets user and token.

pages/reset.vue
<script setup lang="ts">const { resetPassword } = useStrapiAuth()const router = useRouter()const onSubmit = async () => {  try {    await resetPassword({ code: '', password: '', passwordConfirmation: '' })    router.push('/authenticated-page')  } catch (e) {}}</script>

Check out the Strapi Forgot & Reset flow documentation.

changePassword

You can also update an authenticated user password through the /change-password API endpoint:

<script setup lang="ts">const { changePassword } = useStrapiAuth()const onSubmit = async () => {  try {    await changePassword({ currentPassword: '', password: '', passwordConfirmation: '' })    $toast.success('Password changed!')  } catch (e) {}}</script>

Check out the Strapi Change password flow documentation.

sendEmailConfirmation

This action will re-send the confirmation sent after registration.

<script setup lang="ts">const { sendEmailConfirmation } = useStrapiAuth()const onSubmit = async () => {  try {    await sendEmailConfirmation({ email: '' })    alert('Success!')  } catch (e) {}}</script>

Check out the Strapi Email validation documentation.

getProviderAuthenticationUrl

Return the correct URL to authenticate with provider.

pages/login.vue
<script setup lang="ts">const { getProviderAuthenticationUrl } = useStrapiAuth()const onClick = () => {  window.location = getProviderAuthenticationUrl('github')}</script>

authenticateProvider

Authenticate user with external provider. Sets user and token.

pages/auth/[provider]/callback.vue
<script setup lang="ts">const { authenticateProvider } = useStrapiAuth()const route = useRoute()await authenticateProvider('github', route.query.access_token)</script>

fetchUser

Fetch me user from /users/me route if a token exists in the cookies then sets user.

This method is called on the server-side only and the data are hydrated client-side so the HTTP call happens only once. This method is called by default on init through a Nuxt plugin, so you don't have to.
<script setup lang="ts">const { fetchUser } = useStrapiAuth()const user = await fetchUser()</script>

Learn how to populate relations in /users/me route.
