# SQLite Setup
Configure Prisma with SQLite.
## Prerequisites
- None (file-based)
## 1. Schema Configuration
In `prisma/schema.prisma`:
```prisma
datasource db {
provider = "sqlite"
}
generator client {
provider = "prisma-client"
output = "../generated"
}
```
## 2. Config Configuration (v7)
In `prisma.config.ts`:
```typescript
import { defineConfig, env } from 'prisma/config'
export default defineConfig({
schema: 'prisma/schema.prisma',
datasource: {
url: env('DATABASE_URL'),
},
})
```
## 3. Environment Variable
In `.env`:
```env
DATABASE_URL="file:./dev.db"
```
### Connection String Format
```
file:PATH
```
- **PATH**: Relative path to the database file (from `prisma/schema.prisma` location usually, but in v7 check `prisma.config.ts` context). Usually relative to the schema file.
## Driver Adapter (Prisma ORM 7 required)
Prisma ORM 7 uses the query compiler by default, so you must use a driver adapter.
1. Install adapter and driver:
```bash
npm install @prisma/adapter-better-sqlite3 better-sqlite3
```
2. Instantiate Prisma Client with the adapter:
```typescript
import { PrismaClient } from '../generated/client'
import { PrismaBetterSqlite3 } from '@prisma/adapter-better-sqlite3'
const adapter = new PrismaBetterSqlite3({
url: process.env.DATABASE_URL ?? 'file:./dev.db',
})
const prisma = new PrismaClient({ adapter })
```
## Using Driver Adapter (LibSQL / Turso)
For edge compatibility or Turso:
1. Install:
```bash
npm install @prisma/adapter-libsql @libsql/client
```
2. Instantiate:
```typescript
import { PrismaClient } from '../generated/client'
import { PrismaLibSql } from '@prisma/adapter-libsql'
const adapter = new PrismaLibSql({
url: process.env.TURSO_DATABASE_URL,
authToken: process.env.TURSO_AUTH_TOKEN,
})
const prisma = new PrismaClient({ adapter })
```
## Limitations
- **No Enums**: SQLite doesn't support enums (Prisma polyfills them or treats as String).
- **No Scalar Lists**: `String[]` is not supported directly.
- **Concurrency**: Write operations lock the file.
## Common Issues
### "Database file not found"
Ensure the path in `DATABASE_URL` is correct relative to where Prisma is running or the schema file. `file:./dev.db` creates it next to schema.
