## Building the app

Let's start building the Next.js app from scratch.

### Initialize a Next.js app

We can use [`create-next-app`](https://nextjs.org/docs/getting-started) to initialize an app called `supabase-nextjs`:

<Tabs

  defaultActiveId="js"

<TabPanel id="js" label="JavaScript">

```bash
npx create-next-app@latest --use-npm supabase-nextjs
cd supabase-nextjs
```

</TabPanel>
<TabPanel id="ts" label="TypeScript">

```bash
npx create-next-app@latest --ts --use-npm supabase-nextjs
cd supabase-nextjs
```

</TabPanel>
</Tabs>

Then install the Supabase client library: [supabase-js](https://github.com/supabase/supabase-js)

```bash
npm install @supabase/supabase-js
```

And finally we want to save the environment variables in a `.env.local`.
Create a `.env.local` file at the root of the project, and paste the API URL and the `anon` key that you copied [earlier](#get-the-api-keys).

```bash .env.local
NEXT_PUBLIC_SUPABASE_URL=YOUR_SUPABASE_URL
NEXT_PUBLIC_SUPABASE_ANON_KEY=YOUR_SUPABASE_ANON_KEY
```

### App styling (optional)

An optional step is to update the CSS file `app/globals.css` to make the app look nice.
You can find the full contents of this file [here](https://raw.githubusercontent.com/supabase/supabase/master/examples/user-management/nextjs-user-management/app/globals.css).

### Supabase Server-Side Auth

Next.js is a highly versatile framework offering pre-rendering at build time (SSG), server-side rendering at request time (SSR), API routes, and middleware edge-functions.

To better integrate with the framework, we've created the `@supabase/ssr` package for Server-Side Auth. It has all the functionalities to quickly configure your Supabase project to use cookies for storing user sessions. See the [Next.js Server-Side Auth guide](/docs/guides/auth/server-side/nextjs) for more information.

Install the package for Next.js.

```bash
npm install @supabase/ssr
```

### Supabase utilities

There are two different types of clients in Supabase:

1. **Client Component client** - To access Supabase from Client Components, which run in the browser.
2. **Server Component client** - To access Supabase from Server Components, Server Actions, and Route Handlers, which run only on the server.

It is recommended to create the following essential utilities files for creating clients, and organize them within `utils/supabase` at the root of the project.

Create a `client.js` and a `server.js` with the following functionalities for client-side Supabase and server-side Supabase, respectively.

<CH.Code className="min-h-[30rem]">

  return createBrowserClient(
    process.env.NEXT_PUBLIC_SUPABASE_URL!,
    process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY!
  )
}
```

```jsx utils/supabase/server.js
import { createServerClient } from '@supabase/ssr'
import { cookies } from 'next/headers'

  const cookieStore = cookies()

  // Create a server's supabase client with newly configured cookie,
  // which could be used to maintain user's session
  return createServerClient(

### Next.js middleware

Since Server Components can't write cookies, you need middleware to refresh expired Auth tokens and store them. This is accomplished by:

- Refreshing the Auth token with the call to `supabase.auth.getUser`.
- Passing the refreshed Auth token to Server Components through `request.cookies.set`, so they don't attempt to refresh the same token themselves.
- Passing the refreshed Auth token to the browser, so it replaces the old token. This is done with `response.cookies.set`.

You could also add a matcher, so that the middleware only runs on route that access Supabase. For more information, check out this [documentation](https://nextjs.org/docs/app/building-your-application/routing/middleware#matching-paths).

<Admonition type="danger">

Be careful when protecting pages. The server gets the user session from the cookies, which can be spoofed by anyone.

Always use `supabase.auth.getUser()` to protect pages and user data.

_Never_ trust `supabase.auth.getSession()` inside server code such as middleware. It isn't guaranteed to revalidate the Auth token.

It's safe to trust `getUser()` because it sends a request to the Supabase Auth server every time to revalidate the Auth token.

## Set up a login page

### Login and Signup form

Create a login/signup page for your application:

  defaultActiveId="js"
  queryGroup="language"

<TabPanel id="js" label="JavaScript">

Create a new folder named `login`, containing a `page.jsx` file with a login/signup form.

```jsx app/login/page.jsx
import { login, signup } from './actions'

export default function LoginPage() {
  return (
    <form>
      <label htmlFor="email">Email:</label>
      <input id="email" name="email" type="email" required />
      <label htmlFor="password">Password:</label>
      <input id="password" name="password" type="password" required />
      <button formAction={login}>Log in</button>
      <button formAction={signup}>Sign up</button>
    </form>
  )
}
```

</TabPanel>

<TabPanel id="ts" label="TypeScript">

Create a new folder named `login`, containing a `page.tsx` file with a login/signup form.

```tsx app/login/page.tsx
import { login, signup } from './actions'

export default function LoginPage() {
  return (
    <form>
      <label htmlFor="email">Email:</label>
      <input id="email" name="email" type="email" required />
      <label htmlFor="password">Password:</label>
      <input id="password" name="password" type="password" required />
      <button formAction={login}>Log in</button>
      <button formAction={signup}>Sign up</button>
    </form>
  )
}
```

</TabPanel>

</Tabs>

Navigate to `http://localhost:3000/login`. You should see your login form, but it's not yet hooked up to the actual login function. Next, you need to create the login/signup actions. They will:

- Retrieve the user's information.
- Send that information to Supabase as a signup request, which in turns will send a confirmation email.
- Handle any error that arises.

<Admonition type="caution">

Note that cookies is called before any calls to Supabase, which opts fetch calls out of Next.js's caching. This is important for authenticated data fetches, to ensure that users get access only to their own data.

See the Next.js docs to learn more about [opting out of data caching](https://nextjs.org/docs/app/building-your-application/data-fetching/fetching-caching-and-revalidating#opting-out-of-data-caching).

When you enter your email and password, you will receive an email with the title **Confirm Your Signup**. Congrats 🎉!!!

</Tabs>

### Email template

Change the email template to support a server-side authentication flow.

Before we proceed, let's change the email template to support sending a token hash:

- Go to the [Auth templates](/dashboard/project/_/auth/templates) page in your dashboard.
- Select `Confirm signup` template.
- Change `{{ .ConfirmationURL }}` to `{{ .SiteURL }}/auth/confirm?token_hash={{ .TokenHash }}&type=email`.

<Admonition type="tip">

Did you know? You could also customize emails sent out to new users, including the email's looks, content, and query parameters. Check out the [settings of your project](/dashboard/project/_/auth/templates).

</Admonition>

### Confirmation endpoint

As we are working in a server-side rendering (SSR) environment, it is necessary to create a server endpoint responsible for exchanging the `token_hash` for a session.

In the following code snippet, we perform the following steps:

- Retrieve the code sent back from the Supabase Auth server using the `token_hash` query parameter.
- Exchange this code for a session, which we store in our chosen storage mechanism (in this case, cookies).
- Finally, we redirect the user to the `account` page.

Create an account page for the `AccountForm` component we just created

<Tabs
  scrollable
  size="small"
  type="underlined"

### Sign out

Let's create a route handler to handle the signout from the server side. Make sure to check if the user is logged in first!

  const supabase = createClient()

  // Check if a user's logged in
  const {
    data: { user },
  } = await supabase.auth.getUser()

  if (user) {
    await supabase.auth.signOut()

  revalidatePath('/', 'layout')
  return NextResponse.redirect(new URL('/login', req.url), {
    status: 302,
  })
}

### Launch!

Now that we have all the pages, route handlers and components in place, let's run this in a terminal window:

```bash
npm run dev
```

And then open the browser to [localhost:3000](http://localhost:3000) and you should see the completed app.

## Bonus: Profile photos

Every Supabase project is configured with [Storage](/docs/guides/storage) for managing large files like
photos and videos.

### Create an upload widget

Let's create an avatar widget for the user so that they can upload a profile photo. We can start by creating a new component:

<Tabs
  scrollable
  size="small"
  type="underlined"
  defaultActiveId="js"
  queryGroup="language"
>

<TabPanel id="js" label="JavaScript">

```jsx app/account/avatar.jsx
'use client'
import React, { useEffect, useState } from 'react'
import { createClient } from '@/utils/supabase/client'
import Image from 'next/image'

export default function Avatar({ uid, url, size, onUpload }) {
  const supabase = createClient()
  const [avatarUrl, setAvatarUrl] = useState(url)
  const [uploading, setUploading] = useState(false)

  useEffect(() => {
    async function downloadImage(path) {
      try {
        const { data, error } = await supabase.storage.from('avatars').download(path)
        if (error) {
          throw error
        }

        const url = URL.createObjectURL(data)
        setAvatarUrl(url)
      } catch (error) {
        console.log('Error downloading image: ', error)
      }
    }

    if (url) downloadImage(url)
  }, [url, supabase])

  const uploadAvatar = async (event) => {
    try {

      if (!event.target.files || event.target.files.length === 0) {

      }

      const file = event.target.files[0]
      const fileExt = file.name.split('.').pop()
      const filePath = `${uid}-${Math.random()}.${fileExt}`

      const { error: uploadError } = await supabase.storage.from('avatars').upload(filePath, file)

      if (uploadError) {

      }

      onUpload(filePath)
    } catch (error) {
      alert('Error uploading avatar!')

  return (

        />
      ) : (
        <div className="avatar no-image" style={{ height: size, width: size }} />
      )}
      <div style={{ width: size }}>
        <label className="button primary block" htmlFor="single">
          {uploading ? 'Uploading ...' : 'Upload'}
        </label>
        <input

  const supabase = createClient()
  const [avatarUrl, setAvatarUrl] = useState<string | null>(url)
  const [uploading, setUploading] = useState(false)

  useEffect(() => {
    async function downloadImage(path: string) {
      try {
        const { data, error } = await supabase.storage.from('avatars').download(path)
        if (error) {
          throw error
        }

        const url = URL.createObjectURL(data)

      if (!event.target.files || event.target.files.length === 0) {

      }

      const file = event.target.files[0]
      const fileExt = file.name.split('.').pop()
      const filePath = `${uid}-${Math.random()}.${fileExt}`

      const { error: uploadError } = await supabase.storage.from('avatars').upload(filePath, file)

          disabled={uploading}
        />
      </div>
    </div>
  )
}
```

</TabPanel>

</Tabs>

### Add the new widget

And then we can add the widget to the `AccountForm` component:

<Tabs
  scrollable
  size="small"
  type="underlined"
  defaultActiveId="js"
  queryGroup="language"
>

<TabPanel id="js" label="JavaScript">

```jsx app/account/account-form.jsx
// Import the new component
import Avatar from './avatar'

// ...

return (
  <div className="form-widget">
    {/* Add to the body */}
    <Avatar
      uid={user?.id}
      url={avatar_url}
      size={150}
      onUpload={(url) => {
        setAvatarUrl(url)
        updateProfile({ fullname, username, website, avatar_url: url })
      }}
    />
    {/* ... */}
  </div>
)
```

</TabPanel>

<TabPanel id="ts" label="TypeScript">

```tsx app/account/account-form.tsx
// Import the new component
import Avatar from './avatar'

// ...

return (
  <div className="form-widget">
    {/* Add to the body */}
    <Avatar
      uid={user?.id ?? null}
      url={avatar_url}
      size={150}
      onUpload={(url) => {
        setAvatarUrl(url)
        updateProfile({ fullname, username, website, avatar_url: url })
      }}
    />
    {/* ... */}
  </div>
)
```

</TabPanel>

</Tabs>

At this stage you have a fully functional application!
