Database Tools incl. ORM, Migrations and Admin UI (Postgres, MySQL & MongoDB)

Website • Docs • Examples • Blog • Slack • Twitter • Prisma Framework (Preview)

Prisma replaces traditional ORMs and simplifies database workflows:

• Access: Type-safe database access with the auto-generated Prisma client (in JavaScript, TypeScript, Go)
• Migrate: Declarative data modelling and migrations (optional)
• Manage: Visual data management with Prisma Admin

It is used to build GraphQL, REST, gRPC APIs and more. Prisma currently supports MySQL, PostgreSQL, MongoDB.

A new version of Prisma, the Prisma Framework (initially called Prisma 2), is currently in Preview. It doesn’t require a database proxy server and features a more modular architecture based on three tools: Photon.js, Lift and Studio. Follow the development of the Prisma Framework on: isprisma2ready.com.

Get started with the tutorial or some ready-to-run examples.

Quickstart

Get started with Prisma from scratch (or use your existing database):

1. Install Prisma via Homebrew

brew tap prisma/prisma
brew install prisma

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

If you don’t want to use Docker to host the Prisma server as a database proxy, be sure to check out the new Prisma Framework which removes the need for the Prisma server.

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 datamodel

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

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

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

4. Deploy datamodel & migrate database

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 (Node.js)

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 Node.js.

Inside the hello-world directory, install the prisma-client-lib dependency:

npm install --save prisma-client-lib

To generate the Prisma client, run the following command:

prisma generate

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

touch index.js

Add the following code to it:

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

// 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.createUser({
    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()
  console.log(allUsers)

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

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

Finally, run the code using the following command:

node index.js

const usersCalledAlice = await prisma
  .users({
    where: {
      name: "Alice"
    }
  })

// replace the __USER_ID__ placeholder with an actual user ID
const updatedUser = await prisma
  .updateUser({
    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" })
  .posts()

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

Upcoming Connectors

Prisma 1 is currently in maintenance mode in favor of the development of the Prisma Framework. The data source connectors listed below will be implemented in the scope of the Prisma Framework instead of Prisma 1.

If you are interested to participate in the preview for one of the following connectors, please reach out in our Slack.

• Elastic Search
• MS SQL
• Oracle
• ArangoDB
• Neo4j
• Druid
• Dgraph
• DynamoDB
• Cloud Firestore
• CockroachDB
• Cassandra

Prisma Framework Preview

Prisma 2 splits up Prisma’s core functionality into 2 standalone tools:

• Photon: Type-safe database access
• Lift: Declarative data modeling and migrations

Photon and Lift are currently in Preview! Get started with the tutorial or some ready-to-run examples.

You can track the progress of Prisma 2 on isprisma2ready.com or follow the development of the technical specification.
