Next.js & Prisma Postgres Auth Starter
This repository provides a boilerplate to quickly set up a Next.js demo application with authentication using NextAuth.js v4, Prisma Postgres and Prisma ORM, and deploy it to Vercel. It includes an easy setup process and example routes that demonstrate basic CRUD operations against the database.
Features
- Next.js 15 app with App Router, Server Actions & API Routes
- Data modeling, database migrations, seeding & querying
- Log in and sign up authentication flows
- CRUD operations to create, view and delete blog posts
- Pagination, filtering & relations queries
Getting started
1. Install dependencies
After cloning the repo and navigating into it, install dependencies:
npm install1. Create a Prisma Postgres instance
Create a Prisma Postgres instance by running the following command:
npx prisma init --dbThis command is interactive and will prompt you to:
- Log in to the Prisma Console
- Select a region for your Prisma Postgres instance
- Give a name to your Prisma project
Once the command has terminated, copy the Database URL from the terminal output. You'll need it in the next step when you configure your .env file.
2. Set up your .env file
You now need to configure your database connection via an environment variable.
First, create an .env file:
touch .envThen update the .env file by replacing the existing DATABASE_URL value with the one you previously copied. It will look similar to this:
DATABASE_URL="prisma+postgres://accelerate.prisma-data.net/?api_key=PRISMA_POSTGRES_API_KEY"To ensure your authentication works properly, you'll also need to set env vars for NextAuth.js:
AUTH_SECRET="RANDOM_32_CHARACTER_STRING"You can generate a random 32 character string for the AUTH_SECRET secret with this command:
npx auth secretIn the end, your entire .env file should look similar to this (but using your own values for the env vars):
DATABASE_URL="prisma+postgres://accelerate.prisma-data.net/?api_key=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhcGlfa2V5IjoiMWEzMjBiYTEtYjg2Yy00ZTA5LThmZTktZDBhODA3YjQwZjBkIiwidGVuYW50X2lkIjoiY2RhYmM3ZTU1NzdmMmIxMmM0ZTI1Y2IwNWJhZmZhZmU4NjAxNzkxZThlMzhlYjI1NDgwNmIzZjI5NmU1NTkzNiIsImludGVybmFsX3NlY3JldCI6ImI3YmQzMjFhLTY2ODQtNGRiMC05ZWRiLWIyMGE2ZTQ0ZDMwMSJ9.JgKXQBatjjh7GIG3_fRHDnia6bDv8BdwvaX5F-XdBfw"

Run the following commands to set up your database and Prisma schema:
npx prisma migrate dev --name init4. Seed the database
Add initial data to your database:
npx prisma db seed# Using yarnyarn prisma db seed
# Using pnpmpnpm prisma db seed
# Using bunbun prisma db seed5. Run the app
Start the development server:
npm run dev# Using yarnyarn dev
# Using pnpmpnpm run dev
# Using bunbun run devOnce the server is running, visit http://localhost:3000 to start using the app.
