+
+## Overview
+
+NextAuth.js is a complete open source authentication solution.
+
+This is an example application that shows how `next-auth` is applied to a basic Gatsby app. We are showing how to configure the backend both as a [Vercel Function](https://vercel.com/docs/concepts/functions/introduction) for deployment to Vercel, and also for [Gatsby Functions](https://www.gatsbyjs.com/docs/reference/functions) for other platforms.
+
+The deployed version can be found at [`next-auth-gatsby-example.vercel.app`](https://next-auth-gatsby-example.vercel.app)
+
+### About NextAuth.js
+
+NextAuth.js is an easy to implement, full-stack (client/server) open source authentication library originally designed for [Next.js](https://nextjs.org) and [Serverless](https://vercel.com), but this example shows how to use it in a Gatsby project. Our goal is to [support even more frameworks](https://github.com/nextauthjs/next-auth/issues/2294) in the future.
+
+Go to [next-auth.js.org](https://next-auth.js.org) for more information and documentation.
+
+> *NextAuth.js is not officially associated with Vercel or Next.js.*
+
+## Getting Started
+
+### 1. Clone the repository and install dependencies
+
+```
+git clone https://github.com/nextauthjs/next-auth-gatsby-example.git
+cd next-auth-gatsby-example
+npm install
+```
+
+### 2. Configure your local environment
+
+Copy the .env.local.example file in this directory to .env.local (which will be ignored by Git):
+
+```
+cp .env.local.example .env.local
+```
+
+Add details for one or more providers (e.g. Google, Twitter, GitHub, Email, etc).
+
+#### Database
+
+A database is needed to persist user accounts and to support email sign in. However, you can still use NextAuth.js for authentication without a database by using OAuth for authentication. If you do not specify a database, [JSON Web Tokens](https://jwt.io/introduction) will be enabled by default.
+
+You **can** skip configuring a database and come back to it later if you want.
+
+For more information about setting up a database, please check out the following links:
+
+* Docs: [next-auth.js.org/adapters/overview](https://next-auth.js.org/adapters/overview)
+
+### 3. Configure Authentication Providers
+
+1. Review and update options in `nextauth.config.js` as needed.
+
+2. When setting up OAuth, in the developer admin page for each of your OAuth services, you should configure the callback URL to use a callback path of `{server}/api/auth/callback/{provider}`.
+
+  e.g. For Google OAuth you would use: `http://localhost:3000/api/auth/callback/google`
+
+  A list of configured providers and their callback URLs is available from the endpoint `/api/auth/providers`. You can find more information at https://next-auth.js.org/configuration/providers/oauth
+
+3. You can also choose to specify an SMTP server for passwordless sign in via email.
+
+### 4. Start the application
+
+To run your site locally, use:
+
+```
+npm run dev
+```
+
+To run it in production mode, use:
+
+```
+npm run build
+npm run start
+```
+
+### 5. Preparing for Production
+
+Follow the [Deployment documentation](https://next-auth.js.org/deployment)

-## Overview
-
-Auth.js is a complete open source authentication solution.
-
-This is an example application that shows how `@auth/core` is applied to a basic Gatsby app. We are showing how to configure the backend both as a [Vercel Function](https://vercel.com/docs/concepts/functions/introduction) for deployment to Vercel, and also for [Gatsby Functions](https://www.gatsbyjs.com/docs/reference/functions) for other platforms.
-
-The deployed version can be found at [`next-auth-gatsby-example.vercel.app`](https://next-auth-gatsby-example.vercel.app)
-
-### About Auth.js
-
-Auth.js is an easy to implement, full-stack (client/server) open source authentication library originally designed for [Next.js](https://nextjs.org) and [Serverless](https://vercel.com), but this example shows how to use it in a Gatsby project. Our goal is to [support even more frameworks](https://github.com/nextauthjs/next-auth/issues/2294) in the future.
-
-Go to [authjs.dev](https://authjs.dev) for more information and documentation.
-
-> Auth.js is not officially associated with Vercel or Next.js._
-
-## Getting Started
-
-### 1. Clone the repository and install dependencies
-
-```
-git clone https://github.com/nextauthjs/next-auth-gatsby-example.git
-cd next-auth-gatsby-example
-npm install
-```
-
-### 2. Configure your local environment
-
-Copy the .env.local.example file in this directory to .env.local (which will be ignored by Git):
-
-```
-cp .env.local.example .env.local
-```
-
-Add details for one or more providers (e.g. Google, Twitter, GitHub, Email, etc).
-
-#### Database
-
-A database is needed to persist user accounts and to support email sign in. However, you can still use Auth.js for authentication without a database by using OAuth for authentication. If you do not specify a database, [JSON Web Tokens](https://jwt.io/introduction) will be enabled by default.
-
-You **can** skip configuring a database and come back to it later if you want.
-
-For more information about setting up a database, please check out the following links:
-
-- Docs: [authjs.dev/reference/adapters/overview](https://authjs.dev/reference/adapters/overview)
-
-### 3. Configure Authentication Providers
-
-1. Review and update options in `nextauth.config.js` as needed.
-
-2. When setting up OAuth, in the developer admin page for each of your OAuth services, you should configure the callback URL to use a callback path of `{server}/api/auth/callback/{provider}`.
-
-e.g. For Google OAuth you would use: `http://localhost:3000/api/auth/callback/google`
-
-A list of configured providers and their callback URLs is available from the endpoint `/api/auth/providers`. You can find more information at [authjs.dev/reference/providers/oauth-builtin](https://authjs.dev/reference/providers/oauth-builtin).
-
-3. You can also choose to specify an SMTP server for passwordless sign in via email.
-
-### 4. Start the application
-
-To run your site locally, use:
-
-```
-npm run dev
-```
-
-To run it in production mode, use:
-
-```
-npm run build
-npm run start
-```
-
-### 5. Preparing for Production
-
-Follow the [Deployment documentation](https://authjs.dev/guides/basics/deployment)

-Nuxt 3 support with Auth.js is currently experimental. This directory contains a minimal, proof-of-concept application. Parts of this is expected to be abstracted away into a package like `@auth/nuxt`.
+NextAuth.js is committed to bringing easy authentication to other frameworks. [#2294](https://github.com/nextauthjs/next-auth/issues/2294)
+
+Nuxt 3 support with NextAuth.js is currently experimental. This directory contains a minimal, proof-of-concept application. Parts of this is expected to be abstracted away into a package like` @next-auth/nuxt.`

+This package uses Nuxt's [module starter](https://github.com/nuxt/starter/tree/module).
+
+Demo: https://next-auth-nuxt-demo.vercel.app
 
 ## Getting Started
 
-1. Setup your environment variables in `nuxt.config.ts`:
+### Add the module to the modules section of `nuxt.config.ts`:
 
 ```ts
 export default defineNuxtConfig({
+  // temporary module name.
+  modules: ['next-auth-nuxt'],
   // https://v3.nuxtjs.org/migration/runtime-config#runtime-config
   runtimeConfig: {
     secret: process.env.NEXTAUTH_SECRET
@@ -15,36 +23,86 @@ export default defineNuxtConfig({

+  alias: {
+    'next-auth/providers/github': 'node_modules/next-auth/providers/github.js'
   }
 })
 ```
 
-2. Set up Auth.js options
+### Add API route
 
-Go to the API handler file (`server/api/auth/[...].ts`) and setup your providers. This file contains the dynamic route handler for Auth.js which will also contain all of your global Auth.js configurations.
-
-Here's an example of what it looks like:
+To add `NextAuth.js` to a project create a file called `[...].ts` in `server/api/auth`. This contains the dynamic route handler for NextAuth.js which will also contain all of your global NextAuth.js configurations.
 
 ```ts
-// server/api/auth/[...].ts
-
-import { NuxtAuthHandler } from '@/lib/auth/server'
-import GithubProvider from '@auth/core/providers/github'
-import type { AuthOptions } from '@auth/core'
+// ~/server/api/auth/[...].ts
+import { NextAuthNuxtHandler } from 'next-auth-nuxt/handler'
+import GithubProvider from 'next-auth/providers/github'
 
 const runtimeConfig = useRuntimeConfig()
 
-export const authOptions: AuthOptions = {
+export const authOptions = {
   secret: runtimeConfig.secret,
   providers: [
     GithubProvider({
       clientId: runtimeConfig.github.clientId,
       clientSecret: runtimeConfig.github.clientSecret
-    })
-  ]
+    }),
+  ],
 }
 
-export default NuxtAuthHandler(authOptions)
+export default NextAuthNuxtHandler(authOptions)
 ```
 
-All requests to `/api/auth/*` (`signIn`, `callback`, `signOut`, etc.) will automatically be handled by Auth.js.

+
+### Frontend - Add Vue Composable
+
+The `useSession()` Vue Composable is the easiest way to check if someone is signed in.
+
+```html
+<script setup lang="ts">
+const { data: session } = useSession()
+</script>
+
+<template>
+  <div v-if="session">
+    Signed in as {{ session.user.email }} <br />
+    <button @click="signOut">Sign out</button>
+  </div>
+  <div v-else>
+    Not signed in <br />
+    <button @click="signIn">Sign in</button>
+  </div>
+</template>
+```
+
+### Backend - API Route
+
+To protect an API Route, you can use the `getServerSession()` method.
+
+```ts
+import { getServerSession } from 'next-auth-nuxt/handler'
+import { authOptions } from '~/server/api/auth/[...]'
+
+export default defineEventHandler(async (event) => {
+  const session = await getServerSession(event, authOptions)
+
+  if (session) {
+    return {
+      content: 'This is protected content. You can access this content because you are signed in.'
+    }
+  }
+
+  return {
+    error: 'You must be signed in to view the protected content on this page.'
+  }
+})
+```
+
+## Development
+
+- Run `pnpm dev:generate` to generate type stubs.
+- Use `pnpm dev` to start `playground` in development mode.
