# Prisma Accelerate Users
Special migration instructions for users of Prisma Accelerate or Prisma Postgres with `prisma://` or `prisma+postgres://` URLs.
## Important
**Do NOT pass Accelerate URLs to driver adapters.**
Driver adapters (like `PrismaPg`) expect direct database connection strings. They will fail with `prisma://` or `prisma+postgres://` URLs.
## Correct v7 Setup for Accelerate
### 1. Keep your Accelerate URL
```env
# .env
DATABASE_URL="prisma://accelerate.prisma-data.net/?api_key=..."
# or
DATABASE_URL="prisma+postgres://accelerate.prisma-data.net/..."
```
### 2. Install Accelerate extension
```bash
npm install @prisma/extension-accelerate
```
### 3. Configure prisma.config.ts
```typescript
import 'dotenv/config'
import { defineConfig, env } from 'prisma/config'
export default defineConfig({
schema: 'prisma/schema.prisma',
datasource: {
url: env('DATABASE_URL'), // Accelerate URL works here
},
})
```
### 4. Instantiate client with accelerateUrl
```typescript
import { PrismaClient } from '../generated/client'
import { withAccelerate } from '@prisma/extension-accelerate'
// Use accelerateUrl instead of adapter
export const prisma = new PrismaClient({
accelerateUrl: process.env.DATABASE_URL,
}).$extends(withAccelerate())
```
## What NOT to Do
```typescript
// ❌ WRONG - Don't use adapter with Accelerate URL
import { PrismaPg } from '@prisma/adapter-pg'
const adapter = new PrismaPg({
connectionString: process.env.DATABASE_URL // This will fail with prisma://
})
```
## Migrations with Accelerate
For migrations, you may need a direct database connection:
### Option 1: Use Accelerate URL for everything
Accelerate URLs work with Prisma CLI commands:
```bash
# Works with Accelerate URL
prisma migrate deploy
prisma db push
```
### Option 2: Use direct URL for migrations
```env
DATABASE_URL="prisma+postgres://..." # For app
DIRECT_DATABASE_URL="postgresql://..." # For migrations
```
```typescript
// prisma.config.ts
export default defineConfig({
datasource: {
url: env('DIRECT_DATABASE_URL'), // Direct URL for CLI
},
})
```
## Prisma Postgres (Cloud)
If using Prisma Postgres cloud database:
### Same approach
```typescript
import { PrismaClient } from '../generated/client'
import { withAccelerate } from '@prisma/extension-accelerate'
export const prisma = new PrismaClient({
accelerateUrl: process.env.DATABASE_URL, // prisma+postgres:// URL
}).$extends(withAccelerate())
```
## Switching Away from Accelerate
If you later switch to direct TCP connection:
```typescript
// Change from accelerateUrl to adapter
import { PrismaClient } from '../generated/client'
import { PrismaPg } from '@prisma/adapter-pg'
const adapter = new PrismaPg({
connectionString: process.env.DATABASE_URL // Direct postgres:// URL
})
export const prisma = new PrismaClient({ adapter })
```
## Caching with Accelerate
The extension enables caching:
```typescript
const users = await prisma.user.findMany({
cacheStrategy: {
ttl: 60, // Cache for 60 seconds
swr: 120, // Stale-while-revalidate for 120 seconds
},
})
```
## Edge Runtime
Accelerate works great in edge runtimes:
```typescript
// Works in Vercel Edge, Cloudflare Workers, etc.
import { PrismaClient } from '../generated/client'
import { withAccelerate } from '@prisma/extension-accelerate'
export const prisma = new PrismaClient({
accelerateUrl: process.env.DATABASE_URL,
}).$extends(withAccelerate())
```
