Prisma is a performant open-source GraphQL ORM-like layer doing the heavy lifting in your GraphQL server. It turns your database into a GraphQL API which can be consumed by your resolvers via GraphQL bindings.

Prisma's auto-generated GraphQL API provides powerful abstractions and modular building blocks to develop flexible and scalable GraphQL backends:

• Type-safe API including filters, aggregations, pagination and transactions.
• Data modeling & migrations with declarative GraphQL SDL.
• Realtime API using GraphQL subscriptions.
• Advanced API composition using GraphQL bindings and schema stitching.
• Works with all frontend frameworks like React, Vue.js, Angular.

Watch this 3-min tutorial or follow the steps below to get started with Prisma.

npm install -g prisma

Run the following command to create the files you need for a new Prisma service.

prisma init hello-world

Then select the Demo server (hosted in Prisma Cloud) and follow the instructions of the interactive CLI prompt.

Edit datamodel.graphql to define your data model using GraphQL SDL:

type Tweet {
  id: ID! @unique
  createdAt: DateTime!
  text: String!
  owner: User!
}

type User {
  id: ID! @unique
  handle: String! @unique
  name: String!
  tweets: [Tweet!]!
}

To deploy your service, run the following command:

prisma deploy

Run the following command to open a GraphQL Playground and start sending queries and mutations:

prisma playground

mutation {
  createUser(
    data: {
      name: "Alice"
      handle: "alice"
    }
  ) {
    id
  }
}

query {
  users {
    id
    name
    tweets {
      id
      createdAt
      text
    }
  }
}

mutation {
  createTweet(
    data: {
      text: "Prisma makes building GraphQL servers fun & easy"
      owner: {
        connect: {
          id: "__USER_ID__"
        }
      }
    }
  ) {
    id
    createdAt
    owner {
      name
    }
  }
}

You can now connect to Prisma's GraphQL API, select what you would like to do next:

• Build a GraphQL server (recommended)
• Access Prisma's GraphQL API from a Node script (coming soon)
• Access Prisma's GraphQL API directly from the frontend (coming soon)

Prisma takes the role of a data access layer in your backend architecture by connecting your API server to your databases. It enables a layered architecture which leads to better separation of concerns and improves maintainability of the entire backend.

Acting as a GraphQL database proxy, Prisma provides a GraphQL-based abstraction for your databases enabling you to read and write data with GraphQL queries and mutations. Using Prisma bindings, you can access Prisma's GraphQL API from your programming language.

Prisma servers run as standalone processes which allows for them to be scaled independently from your API server.

Prisma provides a mapping from your API to your database. In that sense, it solves similar problems as conventional ORMs. The big difference between Prisma and other ORMs is the way how the mapping is implemented.

Prisma takes a radically different approach which avoids the shortcomings and limitations commonly experienced with ORMs. The core idea is that Prisma turns your database into a GraphQL API which is then consumed by your API server (via GraphQL binding). While this makes Prisma particularly well-suited for building GraphQL servers, it can definetely be used in other contexts as well.

Here is how Prisma compares to conventional ORMs:

• Expressiveness: Full flexibility thanks to Prisma's GraphQL API, including relational filters and nested mutations.
• Performance: Prisma uses various optimization techniques to ensure top performance in complex scenarios.
• Architecture: Using Prisma enables a layered and clean architecture, allowing you to focus on your API layer.
• Type safety: Thanks to GraphQL's strong type system you're getting a strongly typed API layer for free.
• Realtime: Out-of-the-box support for realtime updates for all events happening in the database.

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

You can connect the following databases to Prisma already:

• MySQL
• Postgres

More database connectors will follow.

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

• MongoDB Connector
• Elastic Search Connector

We are still collecting use cases and feedback for the API design and feature set of the following connectors:

• MS SQL Connector
• Oracle Connector
• ArangoDB Connector
• Neo4j Connector
• Druid Connector
• Dgraph Connector
• DynamoDB Connector
• Cloud Firestore Connector
• CockroachDB Connector
• Cassandra Connector
• Redis Connector
• AWS Neptune Connector
• CosmosDB Connector
• Influx Connector

The most important component in Prisma is the GraphQL API:

• Query, mutate & stream data via a auto-generated GraphQL CRUD API
• Define your data model and perform migrations using GraphQL SDL

Prisma's auto-generated GraphQL APIs are fully compatible with the OpenCRUD standard.
