CircleCI Slack Status npm version

Prisma is a data layer for modern applications. It replaces traditional ORMs and data access layers with a universal database abstraction used via the Prisma client. Prisma is used to build GraphQL servers, REST APIs & more.

  • Prisma client for various languages such as JavaScript, TypeScript, Flow, Go.
  • Supports multiple databases such as MySQL, PostgreSQL, MongoDB (see all supported databases).
  • Type-safe database access including filters, aggregations, pagination and transactions.
  • Realtime event systems for your database to get notified about database events.
  • Declarative data modeling & migrations (optional) with simple SDL syntax.



1. Install Prisma via Homebrew

brew tap prisma/prisma
brew install prisma
Alternative: Install with NPM or Yarn
npm install -g prisma
# or
yarn global add prisma

2. Connect Prisma to a database

To setup Prisma, you need to have Docker installed. Run the following command to get started with Prisma:

prisma init hello-world

The interactive CLI wizard now helps you with the required setup:

  • Select Create new database (you can also use an existing database or a hosted demo database)
  • Select the database type: MySQL or PostgreSQL
  • Select the language for the generated Prisma client: TypeScript, Flow, JavaScript or Go

Once the wizard has terminated, run the following commands to setup Prisma:

cd hello-world
docker-compose up -d

3. Define your data model

Edit datamodel.prisma to define your data model using SDL syntax. Each model is mapped to a table in your database schema:

type User {
  id: ID! @unique
  email: String @unique
  name: String!
  posts: [Post!]!

type Post {
  id: ID! @unique
  title: String!
  published: Boolean! @default(value: "false")
  author: User

4. Deploy your Prisma API

To deploy your Prisma API, run the following command:

prisma deploy

The Prisma API is deployed based on the datamodel and exposes CRUD & realtime operations for each model in that file.

5. Use the Prisma client (JavaScript)

The Prisma client connects to the Prisma API and lets you perform read and write operations against your database. This section explains how to use the Prisma client from JavaScript.

Create a new Node script inside the hello-world directory:

touch index.js

Now add the following code to it:

const { prisma } = require('./generated/prisma')

// A `main` function so that we can use async/await
async function main() {

  // Create a new user with a new post
  const newUser = await prisma
      name: "Alice",
      posts: {
        create: {
          title: "The data layer for modern apps",
  console.log(`Created new user: ${newUser.name} (ID: ${newUser.id})`)

  // Read all users from the database and print them to the console
  const allUsers = await prisma.users()

  // Read all posts from the database and print them to the console
  const allPosts = await prisma.posts()

main().catch(e => console.error(e))

Finally, run the code using the following command:

node index.js
See more API operations

const usersCalledAlice = await prisma
    where: {
      name: "Alice"
// replace the __USER_ID__ placeholder with an actual user ID
const updatedUser = await prisma
    where: { id: "__USER_ID__" },
    data: { email: "alice@prisma.io" }
// replace the __USER_ID__ placeholder with an actual user ID
 const deletedUser = await prisma
  .deleteUser({ id: "__USER_ID__" })
const postsByAuthor = await prisma
  .user({ email: "alice@prisma.io" })

Prisma takes the role of the data layer in your backend architecture, replacing traditional ORMs and custom data access layers. It enables a layered architecture which leads to better separation of concerns and improves maintainability of the entire backend.

The Prisma client is used inside your application server to perform read and write operations against your database through the Prisma API.

Prisma runs as standalone processes which allows for it to be scaled independently from your application server.

Database Connectors

Database connectors provide the link between Prisma and the underlying database.

You can connect the following databases to Prisma already:

  • MySQL
  • PostgreSQL
  • MongoDB (alpha)
