Nuxt Auth Sanctum

This module provides a simple way to use Laravel Sanctum with Nuxt by leveraging cookies-based authentication. SSR-ready!

Features

• useSanctumAuth composable for easy access to the current user and authentication methods
• Automated CSRF token header and cookie management
• Both CSR and SSR modes support
• Pre-configured middleware for pages that require authentication
• Cast current user information to any class you want
• Compatible with default Nuxt ofetch client
• TypeScript support

Note: Before using this module, please make sure that you have already configured Laravel Sanctum on your backend. You can find more information about Laravel Sanctum here.

Quick Setup

1. Add nuxt-auth-sanctum dependency to your project

# Using pnpm
pnpm add -D nuxt-auth-sanctum

# Using yarn
yarn add --dev nuxt-auth-sanctum

# Using npm
npm install --save-dev nuxt-auth-sanctum

2. Add nuxt-auth-sanctum to the modules section of nuxt.config.ts

export default defineNuxtConfig({
    modules: ['nuxt-auth-sanctum'],

    // nuxt-auth-sanctum options (also configurable via environment variables)
    sanctum: {
        baseUrl: 'http://localhost:80', // Laravel API
        origin: 'http://localhost:3000', // Nuxt app
    },
});

That's it! You can now use Nuxt Auth Sanctum in your Nuxt app ✨

Usage

In this package you can find the following:

• composables
  • useSanctumAuth - provides access to the current user and authentication methods
  • useSanctumUser - provides access to the current user
  • useSanctumClient - provides access to the ofetch client with pre-configured CSRF token header and cookie management
• middleware
  • sanctum:auth - middleware for pages that require authenticated user
  • sanctum:guest - middleware for pages that require guest user

Composables

1. useSanctumUser

This composable provides access to the current authenticated user. It supports generic types, so you can get the user as any class you want.

interface MyCustomUser {
    id: number;
    login: string;
    custom_metadata: {
        group: string;
        role: string;
    };
}

const user = useSanctumUser<MyCustomUser>();

If there is no authenticated user, the composable will return null.

2. useSanctumAuth

Composable provides 2 computed properties and 2 methods:

• user - current authenticated user (basically the same as useSanctumUser)
• isAuthenticated - boolean flag indicating whether the user is authenticated or not
• login - method for logging in the user
• logout - method for logging out the user

To authenticate a user you should pass credentials payload as an argument to the login method. The payload should contain all fields that are required by your Laravel Sanctum backend.

const { login } = useSanctumAuth();

const userCredentials = {
    email: 'user@mail.com',
    password: '123123',
};

await login(userCredentials);

If login operation was successful, the user property will be updated with the current user information returned by the Laravel API.

By default, methods will use the following Laravel endpoints:

• /login to authenticate the user
• /logout to log out the user
• /api/user to get the current user information
• /sanctum/csrf-cookie to get the CSRF token cookie

To change the default endpoints, please check the Configuration section.

1. useSanctumClient

All previous composables work on top of the ofetch client which can be used in your application as well. The client is pre-configured with CSRF token header and cookie management.

All requests will be sent to the baseUrl specified in the Configuration section.

const client = useSanctumClient();

const { data, pending, error, refresh } = await useAsyncData('users', () =>
    client('/api/users')
);

Since client implements $Fetch interface, you can use it as a regular ofetch client. Check examples in the ofetch documentation.

Middleware

1. sanctum:auth

This middleware checks if the user is authenticated. If not, it will redirect a user to the page specified in the redirect.onAuthOnly option (default is /login).

Also, you might want to remember what page the user was trying to access and redirect him back to that page after successful authentication. To do that, just enable the redirect.keepRequestedRoute option and it will be automatically stored in the URL for later redirect.

If there is no redirect rule the middleware will throw 403 error.

2. sanctum:guest

This middleware checks if the user is not authenticated. If not, it will redirect a user to the page specified in the redirect.onGuestOnly option (default is /).

If there is no redirect rule the middleware will throw 403 error.

Configuration

Here is the full example of the default module configuration:

baseUrl: 'http://localhost:80', // Laravel API
origin: 'http://localhost:3000', // Nuxt app (required for CSRF cookie)
userStateKey: 'sanctum.user.identity', // user state key for Vue `useState` composable
redirectIfAuthenticated: false, // Redirect to onLogin if already authenticated
endpoints: {
    csrf: '/sanctum/csrf-cookie', // CSRF cookie endpoint
    login: '/login', // Endpoint that accepts user credentials
    logout: '/logout', // Endpoint to destroy the current session
    user: '/api/user', // Endpoint that return current user information
},
csrf: {
    cookie: 'XSRF-TOKEN', // CSRF cookie name
    header: 'X-XSRF-TOKEN', // CSRF header name
},
client: {
    retry: false, // ofetch retry option (number | false)
},
redirect: {
    keepRequestedRoute: false, // Keep requested route in the URL for later redirect
    onLogin: '/', // Redirect to this page after successful login
    onLogout: '/', // Redirect to this page after successful logout
    onAuthOnly: '/login', // Redirect to this page if user is not authenticated
    onGuestOnly: '/', // Redirect to this page if user is authenticated
},

You can override any of these options in the nuxt.config.ts file:

export default defineNuxtConfig({
    modules: ['nuxt-auth-sanctum'],

    sanctum: {
        baseUrl: 'http://localhost:80', // Your Laravel API
        origin: 'http://localhost:3000', // Your Nuxt app
        redirect: {
            onLogin: '/dashboard', // Custom route after successful login
        },
    },
});

Also, it is possible to override options via environment variables. It might be useful when you want to use .env file to provide baseUrl for Laravel API.

export default defineNuxtConfig({
    modules: ['nuxt-auth-sanctum'],

    runtimeConfig: {
        public: {
            sanctum: {
                baseUrl: 'http://localhost:80',
            },
        },
    },
});
