## Installation
<BlockItem name="supabase-client-nextjs" description="Supabase Client for Next.js" />
## Folder structure
<RegistryBlock itemName="supabase-client-nextjs" />
## Usage
This block installs a Supabase client for connecting your Next.js project to Supabase. It's designed for use with the App Router and fully supports server-side rendering (SSR).
If you've already set up your Supabase client—either using the `npx create-next-app -e with-supabase` template or another method—you can continue using your existing setup.
### Getting started
After installing the block, you'll have the following environment variables in your `.env.local` file:
```env
NEXT_PUBLIC_SUPABASE_URL=
NEXT_PUBLIC_SUPABASE_PUBLISHABLE_OR_ANON_KEY=
```
- If you're using supabase.com, you can find these values in the [Connect modal](https://supabase.com/dashboard/project/_?showConnect=true) under App Frameworks or in your project's [API settings](https://supabase.com/dashboard/project/_/settings/api).
- If you're using a local instance of Supabase, you can find these values by running `supabase start` or `supabase status` (if you already have it running).
<Callout type="warning" className="mt-4">
{' '}
This Supabase client is built for SSR with the Next.js App Router. If you're building a React SPA,
use the [React SPA client](/ui/docs/react-router/client) instead.{' '}
