# Use Prisma with Bun
Prisma's dynamically loaded subcommands, such as `prisma dev`, require npm to be installed alongside Bun. The commands
used in this guide (`prisma init`, `prisma migrate`, and `prisma generate`) are built into the CLI. Generated code
works with Bun using the `prisma-client` generator.
Create a directory and initialize it with `bun init`.
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
mkdir prisma-app
cd prisma-app
bun init
```
Then install the Prisma CLI (`prisma`), Prisma Client (`@prisma/client`), and the LibSQL adapter as dependencies.
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun add -d prisma
bun add @prisma/client @prisma/adapter-libsql
```
Use the Prisma CLI with `bunx` to initialize the schema and migration directory. This guide uses a local SQLite database file; `prisma init` writes its connection string, `DATABASE_URL="file:./dev.db"`, to `.env`.
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bunx --bun prisma init --datasource-provider sqlite
```
This creates a basic schema. Open `prisma/schema.prisma`, update the generator block to use the Rust-free client with the `bun` runtime, and add a `User` model.
```prisma prisma/schema.prisma icon="https://mintcdn.com/bun-1dd33a4e-farm-de84d354-pm-sbom/IPGjipyt_DGwYrQc/icons/ecosystem/prisma.svg?fit=max&auto=format&n=IPGjipyt_DGwYrQc&q=85&s=abee815276fe6d08fe42f92732963406" theme={"theme":{"light":"github-light","dark":"dracula"}}
generator client {
provider = "prisma-client"
output = "../generated/prisma" // [!code --]
output = "./generated" // [!code ++]
engineType = "client" // [!code ++]
runtime = "bun" // [!code ++]
}
datasource db {
provider = "sqlite"
}
model User { // [!code ++]
id Int @id @default(autoincrement()) // [!code ++]
email String @unique // [!code ++]
name String? // [!code ++]
} // [!code ++]
```
Generate and run the initial migration. This writes a `.sql` migration file to `prisma/migrations`, creates a new SQLite database, and runs the migration against it. Bun [does not load `.env` automatically](/runtime/environment-variables) when it runs a CLI with `--bun`, and the `prisma.config.ts` generated by `prisma init` reads `DATABASE_URL` from the environment, so pass `--env-file=.env` explicitly.
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun run --bun --env-file=.env prisma migrate dev --name init
```
```txt theme={"theme":{"light":"github-light","dark":"dracula"}}
Loaded Prisma config from prisma.config.ts.
Prisma schema loaded from prisma/schema.prisma.
Datasource "db": SQLite database "dev.db" at "file:./dev.db"
SQLite database dev.db created at file:./dev.db
Applying migration `20251014141233_init`
The following migration(s) have been created and applied from new schema changes:
prisma/migrations/
└─ 20251014141233_init/
└─ migration.sql
Your database is now in sync with your schema.
```
`prisma migrate dev` does not generate the *Prisma client*, so generate it with the Prisma CLI. The client provides a fully typed API for reading and writing to your database.
```sh terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun run --bun --env-file=.env prisma generate
```
Create a new file `prisma/db.ts` that initializes the PrismaClient with the LibSQL adapter.
```ts prisma/db.ts icon="https://mintcdn.com/bun-1dd33a4e-farm-de84d354-pm-sbom/IPGjipyt_DGwYrQc/icons/typescript.svg?fit=max&auto=format&n=IPGjipyt_DGwYrQc&q=85&s=4448657ec154e63e3a095030af59c903" theme={"theme":{"light":"github-light","dark":"dracula"}}
import { PrismaClient } from "./generated/client";
import { PrismaLibSql } from "@prisma/adapter-libsql";
const adapter = new PrismaLibSql({ url: process.env.DATABASE_URL || "" });
export const prisma = new PrismaClient({ adapter });
```
Write a script that creates a new user, then counts the users in the database.
```ts index.ts icon="https://mintcdn.com/bun-1dd33a4e-farm-de84d354-pm-sbom/IPGjipyt_DGwYrQc/icons/typescript.svg?fit=max&auto=format&n=IPGjipyt_DGwYrQc&q=85&s=4448657ec154e63e3a095030af59c903" theme={"theme":{"light":"github-light","dark":"dracula"}}
import { prisma } from "./prisma/db";
// create a new user
await prisma.user.create({
data: {
name: "John Dough",
email: `john-${Math.random()}@example.com`,
},
});
// count the number of users
const count = await prisma.user.count();
console.log(`There are ${count} users in the database.`);
```
Run the script with `bun run`. Each run creates a new user.
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun run index.ts
```
```txt theme={"theme":{"light":"github-light","dark":"dracula"}}
There are 1 users in the database.
```
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun run index.ts
```
```txt theme={"theme":{"light":"github-light","dark":"dracula"}}
There are 2 users in the database.
```
```bash terminal icon="terminal" theme={"theme":{"light":"github-light","dark":"dracula"}}
bun run index.ts
```
```txt theme={"theme":{"light":"github-light","dark":"dracula"}}
There are 3 users in the database.
```
***
Prisma is now set up with Bun. See the [Prisma docs](https://www.prisma.io/docs/orm/prisma-client) as you build out your application.
