Building with Prisma and Next.js
Learn how to integrate Prisma ORM with Next.js for robust database operations and type safety.
# Building with Prisma and Next.js
Prisma provides a modern database toolkit that integrates seamlessly with Next.js, offering type safety and excellent developer experience.
## Why Prisma?
### Type Safety
Prisma generates TypeScript types from your database schema, catching errors at compile time.
### Auto-completion
IDE support with intelligent suggestions for database operations.
### Database Agnostic
Switch between databases without changing your application code.
## Setting Up Prisma
### 1. Install Dependencies
```bash
npm install prisma @prisma/client
npm install -D prisma
```
### 2. Initialize Prisma
```bash
npx prisma init
```
### 3. Define Your Schema
```prisma
// prisma/schema.prisma
generator client {
provider = "prisma-client-js"
}
datasource db {
provider = "sqlite"
url = env("DATABASE_URL")
}
model User {
id Int @id @default(autoincrement())
email String @unique
name String?
posts Post[]
}
model Post {
id Int @id @default(autoincrement())
title String
content String?
published Boolean @default(false)
author User @relation(fields: [authorId], references: [id])
authorId Int
}
```
### 4. Generate Client
```bash
npx prisma generate
```
### 5. Run Migrations
```bash
npx prisma migrate dev --name init
```
## Using Prisma in Next.js
### API Routes
```typescript
// app/api/posts/route.ts
import { prisma } from '@/lib/prisma'
export async function GET() {
const posts = await prisma.post.findMany({
include: { author: true }
})
return Response.json(posts)
}
```
### Server Components
```typescript
// app/posts/page.tsx
import { prisma } from '@/lib/prisma'
export default async function PostsPage() {
const posts = await prisma.post.findMany({
where: { published: true },
include: { author: true }
})
return (
{posts.map(post => (
))}
)
}
```
## Best Practices
1. **Use connection pooling** in production
2. **Handle errors gracefully**
3. **Validate input data**
4. **Use transactions** for complex operations
## Database Operations
### Create
```typescript
const user = await prisma.user.create({
data: {
email: 'user@example.com',
name: 'John Doe'
}
})
```
### Read
```typescript
const users = await prisma.user.findMany({
where: { email: { contains: '@' } },
select: { id: true, name: true }
})
```
### Update
```typescript
const updatedUser = await prisma.user.update({
where: { id: 1 },
data: { name: 'Jane Doe' }
})
```
### Delete
```typescript
await prisma.user.delete({
where: { id: 1 }
})
```
