Create a new TypeScript project from scratch by connecting Prisma ORM to MongoDB and generating a Prisma Client for database access

Location: v7 > Prisma ORM > Quickstart > MongoDB

[MongoDB](https://www.mongodb.com) is a popular NoSQL document database. In this guide, you will learn how to set up a new TypeScript project from scratch, connect it to MongoDB using Prisma ORM, and generate a Prisma Client for type-safe access to your database.

> [!WARNING]
> MongoDB support for Prisma ORM v7
> 
> **MongoDB support for Prisma ORM v7 is coming in the near future.** In the meantime, please use **Prisma ORM v6.19** (the latest v6 release) when working with MongoDB.
> 
> This guide uses Prisma ORM v6.19 to ensure full compatibility with MongoDB.

## Prerequisites [#prerequisites]

* Node.js installed in your system [with the supported version](https://www.prisma.io/docs/guides/upgrade-prisma-orm/v6#minimum-supported-nodejs-versions)
* A [MongoDB](https://www.mongodb.com/) database accessible via connection string

## 1. Create a new project [#1-create-a-new-project]

```shell
mkdir hello-prisma
cd hello-prisma
```

Initialize a TypeScript project:

  

#### bun

```bash
bun init
bun add typescript tsx @types/node --dev
bunx tsc --init
```

#### pnpm

```bash
pnpm init
pnpm add typescript tsx @types/node --save-dev
pnpm tsc --init
```

#### yarn

```bash
yarn init
yarn add typescript tsx @types/node --dev
yarn tsc --init
```

#### npm

```bash
npm init
npm install typescript tsx @types/node --save-dev
npx tsc --init
```

## 2. Install required dependencies [#2-install-required-dependencies]

Install the packages needed for this quickstart:

  

#### bun

```bash
bun add prisma@6.19.3 @types/node --dev
```

#### pnpm

```bash
pnpm add prisma@6.19.3 @types/node --save-dev
```

#### yarn

```bash
yarn add prisma@6.19.3 @types/node --dev
```

#### npm

```bash
npm install prisma@6.19.3 @types/node --save-dev
```

  

#### bun

```bash
bun add @prisma/client@6.19.3 dotenv
```

#### pnpm

```bash
pnpm add @prisma/client@6.19.3 dotenv
```

#### yarn

```bash
yarn add @prisma/client@6.19.3 dotenv
```

#### npm

```bash
npm install @prisma/client@6.19.3 dotenv
```

> [!NOTE]
> Prisma v6.19 and MongoDB
> 
> This is the latest stable version of Prisma ORM v6 that fully supports MongoDB. MongoDB support for Prisma ORM v7 is coming soon. You can also install `prisma@6` and `@prisma/client@6` to automatically get the latest v6 release.

Here's what each package does:

* **`prisma`** - The Prisma CLI for running commands like `prisma init`, `prisma db push`, and `prisma generate`
* **`@prisma/client`** - The Prisma Client library for querying your database
* **`dotenv`** - Loads environment variables from your `.env` file

> [!NOTE]
> MongoDB doesn't require driver adapters since Prisma ORM connects directly to MongoDB.

## 3. Configure ESM support [#3-configure-esm-support]

Update `tsconfig.json` for ESM compatibility:

```json title="tsconfig.json"
{
  "compilerOptions": {
    "module": "ESNext",
    "moduleResolution": "bundler",
    "target": "ES2023",
    "strict": true,
    "esModuleInterop": true,
    "ignoreDeprecations": "6.0"
  }
}
```

Update `package.json` to enable ESM:

```json title="package.json"
{
  "type": "module" // [!code ++]
}
```

## 4. Initialize Prisma ORM [#4-initialize-prisma-orm]

You can now run Prisma CLI commands using your package manager:

  

#### bun

```bash
bunx prisma
```

#### pnpm

```bash
pnpm prisma
```

#### yarn

```bash
yarn prisma
```

#### npm

```bash
npx prisma
```

Next, set up your Prisma ORM project by creating your [Prisma Schema](https://www.prisma.io/docs/orm/v7/prisma-schema/overview) file with the following command:

  

#### bun

```bash
bunx --bun prisma init --datasource-provider mongodb --output ../generated/prisma
```

#### pnpm

```bash
pnpm prisma init --datasource-provider mongodb --output ../generated/prisma
```

#### yarn

```bash
yarn prisma init --datasource-provider mongodb --output ../generated/prisma
```

#### npm

```bash
npx prisma init --datasource-provider mongodb --output ../generated/prisma
```

This command does a few things:

* Creates a `prisma/` directory with a `schema.prisma` file for your database connection and schema models
* Creates a `.env` file in the root directory for environment variables
* Creates a `prisma.config.ts` file for Prisma configuration

> [!NOTE]
> Prisma Client will be generated in the `generated/prisma/` directory when you run `npx prisma generate` later in this guide.

The generated `prisma.config.ts` file looks like this:

```typescript title="prisma.config.ts"
import { defineConfig, env } from "prisma/config";

export default defineConfig({
  schema: "prisma/schema.prisma",
  migrations: {
    path: "prisma/migrations",
  },
  engine: "classic",
  datasource: {
    url: env("DATABASE_URL"),
  },
});
```

Add `dotenv` to `prisma.config.ts` so that Prisma can load environment variables from your `.env` file:

```typescript title="prisma.config.ts"
import "dotenv/config"; // [!code ++]
import { defineConfig, env } from "prisma/config";

export default defineConfig({
  schema: "prisma/schema.prisma",
  migrations: {
    path: "prisma/migrations",
  },
  engine: "classic",
  datasource: {
    url: env("DATABASE_URL"),
  },
});
```

The generated schema uses [the ESM-first `prisma-client` generator](https://www.prisma.io/docs/orm/v7/prisma-schema/overview/generators#prisma-client) with a custom output path:

```prisma title="prisma/schema.prisma"
generator client {
  provider = "prisma-client"
  output   = "../generated/prisma"
}

datasource db {
  provider = "mongodb"
  url = env("DATABASE_URL")
}
```

Update your `.env` file with your MongoDB connection string:

```text title=".env"
DATABASE_URL="mongodb+srv://username:password@cluster.mongodb.net/mydb"
```

> [!NOTE]
> Replace `username`, `password`, `cluster`, and `mydb` with your actual MongoDB credentials and database name. You can get your connection string from [MongoDB Atlas](https://www.mongodb.com/cloud/atlas) or your MongoDB deployment.

## 5. Define your data model [#5-define-your-data-model]

Open `prisma/schema.prisma` and add the following models:

```prisma title="prisma/schema.prisma"
generator client {
  provider = "prisma-client"
  output   = "../generated/prisma"
}

datasource db {
  provider = "mongodb"
  url = env("DATABASE_URL")
}

model User { // [!code ++]
  id    String  @id @default(auto()) @map("_id") @db.ObjectId // [!code ++]
  email String  @unique // [!code ++]
  name  String? // [!code ++]
  posts Post[] // [!code ++]
} // [!code ++]

model Post { // [!code ++]
  id        String  @id @default(auto()) @map("_id") @db.ObjectId // [!code ++]
  title     String // [!code ++]
  content   String? // [!code ++]
  published Boolean @default(false) // [!code ++]
  author    User    @relation(fields: [authorId], references: [id]) // [!code ++]
  authorId  String  @db.ObjectId // [!code ++]
} // [!code ++]
```

## 6. Push your schema to MongoDB [#6-push-your-schema-to-mongodb]

MongoDB doesn't support migrations like relational databases. Instead, use `db push` to sync your schema:

  

#### bun

```bash
bunx prisma db push
```

#### pnpm

```bash
pnpm prisma db push
```

#### yarn

```bash
yarn prisma db push
```

#### npm

```bash
npx prisma db push
```

This command:

* Creates the collections in MongoDB based on your schema
* Automatically generates Prisma Client

> [!NOTE]
> Unlike relational databases, MongoDB uses a flexible schema. The `db push` command ensures your Prisma schema is reflected in your database without creating migration files.

## 7. Instantiate Prisma Client [#7-instantiate-prisma-client]

Now that you have all the dependencies installed, you can instantiate Prisma Client:

```typescript title="lib/prisma.ts"
import "dotenv/config";
import { PrismaClient } from "../generated/prisma/client";

const prisma = new PrismaClient();

export { prisma };
```

## 8. Write your first query [#8-write-your-first-query]

Create a `script.ts` file to test your setup:

```typescript title="script.ts"
import { prisma } from "./lib/prisma";

async function main() {
  // Create a new user with a post
  const user = await prisma.user.create({
    data: {
      name: "Alice",
      email: "alice@prisma.io",
      posts: {
        create: {
          title: "Hello World",
          content: "This is my first post!",
          published: true,
        },
      },
    },
    include: {
      posts: true,
    },
  });
  console.log("Created user:", user);

  // Fetch all users with their posts
  const allUsers = await prisma.user.findMany({
    include: {
      posts: true,
    },
  });
  console.log("All users:", JSON.stringify(allUsers, null, 2));
}

main()
  .then(async () => {
    await prisma.$disconnect();
  })
  .catch(async (e) => {
    console.error(e);
    await prisma.$disconnect();
    process.exit(1);
  });
```

Run the script:

  

#### bun

```bash
bunx tsx script.ts
```

#### pnpm

```bash
pnpm dlx tsx script.ts
```

#### yarn

```bash
yarn dlx tsx script.ts
```

#### npm

```bash
npx tsx script.ts
```

You should see the created user and all users printed to the console.

## 9. Explore your data [#9-explore-your-data]

You can use [MongoDB Atlas](https://www.mongodb.com/cloud/atlas), the MongoDB shell, or MongoDB Compass to view and manage your data.

> [!WARNING]
> [Prisma Studio](https://www.prisma.io/docs/studio) does not currently support MongoDB. Support may be added in a future release. See [Databases supported by Prisma Studio](https://www.prisma.io/docs/studio#supported-databases) for more information.
