ra-data-prisma

A react-admin data provider for Prisma. This project is currently under active development. Beta releases will be published regularily. Feedback about your applications/use cases is very welcome!

Installation

Install with:

npm install --save graphql ra-data-prisma

or

yarn add graphql ra-data-prisma

Usage

Create your react-admin app and bootstrap the data provider like so:

import { PostList, PostEdit, PostCreate } from './post';
import buildPrismaProvider from 'ra-data-prisma';

class App extends Component {
    constructor() {
        super();
        this.state = { dataProvider: null };
    }
    componentDidMount() {
        buildPrismaProvider({ client })
            .then(dataProvider => this.setState({ dataProvider }));
    }

    render() {
        const { dataProvider } = this.state;

        if (!dataProvider) {
            return <div>Loading</div>;
        }

        return (
            <Admin dataProvider={dataProvider}>
                <Resource name="Post" list={PostList} edit={PostEdit} create={PostCreate} />
            </Admin>
        );
    }
}

This assumes your have a resource of the type Post, which will be automatically recognized if you provided the CRUD logic for the type in the usual prisma conventions, i.e. you schema should look something like:

type Query {
  
  posts(where: PostWhereInput, orderBy: PostOrderByInput, skip: Int, after: String, before: String, first: Int, last: Int): [Post]!
  post(where: PostWhereUniqueInput!): Post
  postsConnection(where: PostWhereInput, orderBy: PostOrderByInput, skip: Int, after: String, before: String, first: Int, last: Int): PostConnection!

}

type Mutation {
  createPost(data: PostCreateInput!): Post!
  updatePost(data: PostUpdateInput!, where: PostWhereUniqueInput!): Post
  deletePost(where: PostWhereUniqueInput!): Post
}

type Post {
  id: ID!
  text: String!
}

This means you can either hook up your data provider directly to your prisma database or import the types from prisma generated code in your schema and override/customize the resolvers or simply forward them to your database unsing resolver-forwarding. Let the Prisma magic happen :)

I will publish one of our projects using this library as a complete/working sample project.

Options

Customize the Apollo client

You can either supply the client options by calling buildPrismaProvider like this:

buildPrismaProvider({ clientOptions: { uri: 'https://your-prisma-endpoint', ...otherApolloOptions } });

Or supply your client directly with:

buildPrismaProvider({ client: myClient });

Contribute

To include your local fork into a test project, add the library locally to your projects package.json

"dependencies": {
  "ra-data-prisma": "file:../path/to/your/fork/ra-data-prisma",
  ... your other dependencies
}

and run npm i. For me, hot reloading works with my react-admin test app.

To have your changes in the source directory reflect in the lib, remember to build!

yarn build

Remember to always make persistent changes in the ./src/ directory and rebuild. Your dirty work can be done directly in the ./lib/ folder, but will be overriden the next time you build.

For testing, run

jest

The test suite is currently rather thin. If you would like to contribute tests for nested types that would be great :)

Glad about feedback & contributions!
