# Prisma Postgres Setup
|
|
|
|
Configure Prisma with Prisma Postgres (Managed).
|
|
|
|
## Overview
|
|
|
|
Prisma Postgres is a serverless, managed PostgreSQL database optimized for Prisma.
|
|
|
|
## Setup via CLI
|
|
|
|
You can provision a Prisma Postgres instance directly via the CLI:
|
|
|
|
```bash
|
|
prisma init --db
|
|
```
|
|
|
|
This will:
|
|
1. Log you into Prisma Data Platform.
|
|
2. Create a new project and database instance.
|
|
3. Update your `.env` with the connection string.
|
|
|
|
## Connection String
|
|
|
|
For Prisma CLI flows and Accelerate-style usage, you may see a `prisma+postgres://` URL.
|
|
|
|
For Prisma Client with a driver adapter in Node.js, prefer the direct TCP connection string from the Prisma Postgres dashboard:
|
|
|
|
```env
|
|
DATABASE_URL="postgres://identifier:key@db.prisma.io:5432/postgres?sslmode=require"
|
|
```
|
|
|
|
## 1. Schema Configuration
|
|
|
|
In `prisma/schema.prisma`:
|
|
|
|
```prisma
|
|
datasource db {
|
|
provider = "postgresql" // Use postgresql provider
|
|
}
|
|
|
|
generator client {
|
|
provider = "prisma-client"
|
|
output = "../generated"
|
|
}
|
|
```
|
|
|
|
## 2. Config Configuration
|
|
|
|
In `prisma.config.ts`:
|
|
|
|
```typescript
|
|
import { defineConfig, env } from 'prisma/config'
|
|
|
|
export default defineConfig({
|
|
schema: 'prisma/schema.prisma',
|
|
datasource: {
|
|
url: env('DATABASE_URL'),
|
|
},
|
|
})
|
|
```
|
|
|
|
## Driver Adapter
|
|
|
|
Use a driver adapter for Prisma Postgres in the standard SQL workflow.
|
|
|
|
### Recommended for standard Node.js apps
|
|
|
|
1. Install adapter and driver:
|
|
```bash
|
|
npm install @prisma/adapter-pg pg
|
|
```
|
|
|
|
2. Use the direct TCP connection string from Prisma Console:
|
|
```typescript
|
|
import 'dotenv/config'
|
|
import { PrismaClient } from '../generated/client'
|
|
import { PrismaPg } from '@prisma/adapter-pg'
|
|
|
|
const adapter = new PrismaPg({ connectionString: process.env.DATABASE_URL })
|
|
const prisma = new PrismaClient({ adapter })
|
|
```
|
|
|
|
`PrismaPg` also accepts the connection string directly:
|
|
|
|
```typescript
|
|
const adapter = new PrismaPg(process.env.DATABASE_URL!)
|
|
const prisma = new PrismaClient({ adapter })
|
|
```
|
|
|
|
For PostgreSQL prepared statement naming, pass adapter options as the second argument:
|
|
|
|
```typescript
|
|
import { createHash } from 'node:crypto'
|
|
|
|
const adapter = new PrismaPg(process.env.DATABASE_URL!, {
|
|
statementNameGenerator: ({ sql }) =>
|
|
`prisma_${createHash('sha1').update(sql).digest('hex').slice(0, 16)}`,
|
|
})
|
|
```
|
|
|
|
### Edge/serverless option
|
|
|
|
Use the Prisma Postgres serverless driver only when you need HTTP/WebSocket transport in environments like Workers or Edge Functions:
|
|
|
|
```bash
|
|
npm install @prisma/adapter-ppg @prisma/ppg
|
|
```
|
|
|
|
```typescript
|
|
import { PrismaClient } from '../generated/client'
|
|
import { PrismaPostgresAdapter } from '@prisma/adapter-ppg'
|
|
|
|
const prisma = new PrismaClient({
|
|
adapter: new PrismaPostgresAdapter({
|
|
connectionString: process.env.PRISMA_DIRECT_TCP_URL,
|
|
}),
|
|
})
|
|
```
|
|
|
|
This serverless driver is the specialized path for HTTP/WebSocket-based edge and serverless runtimes, not the default recommendation for standard Node.js apps.
|
|
|
|
## Features
|
|
|
|
- **Serverless**: Scales to zero.
|
|
- **Caching**: Integrated query caching (Accelerate).
|
|
- **Real-time**: Database events (Pulse).
|
|
|
|
## Using with Prisma Client
|
|
|
|
Use the Prisma Postgres adapter shown above when instantiating Prisma Client.
