Supabase Authentication

Configure the Supabase authentication service

Supabase is an open source Firebase alternative that provides a Postgres database, authentication, and real-time data sync.

Install#

Install the Supabase auth service in the Next.js app.

yarn workspace web add @acme/auth-supabase

Configure#

Edit apps/web/.env and add your public Supabase URL and KEY. You can find your project URL and KEY in the Supabase console.

NEXT_PUBLIC_SUPABASE_URL="https://x.supabase.co"
NEXT_PUBLIC_SUPABASE_KEY="x"

Edit apps/web/features/auth/auth-service and create the supabase authentication service.

import { createAuthService } from '@acme/auth-supabase/client'


export const authService = createAuthService()

Update the next.js Middleware apps/web/middleware.ts to use the Supabase authentication service.

import { auth } from '@acme/auth-supabase/middleware'


export default auth

Replace all getSession imports with the getSession from @acme/auth-supabase in the following files:

  • apps/web/app/(app)/layout.tsx
  • apps/web/app/api/trpc/[trpc]/route.ts
  • apps/web/lib/trpc/rsc.ts

If you have any other files that use getSession you will need to replace them as well.

import { getSession } from '@acme/auth-supabase'

Now your frontend is configured to use Supabase authentication.

Try it out by running yarn dev:web and navigating to http://localhost:3000.
