ra-data-hasura

react-admin data provider for Hasura GraphQL Engine

Installation

$ npm install --save ra-data-hasura

Usage

The ra-data-hasura provider accepts three arguments:

  • serverEndpoint - The URL at which Hasura GraphQL Engine is running. (for example: http://localhost:8080). This is required. It should also expose /v1/query endpoint.

  • headers - An optional argument. Pass your auth headers here.

  • config - An optional argument. Pass your config here.

hasuraDataProvider(serverEndpoint, headers, config)

In the following example, we import hasuraDataProvider from ra-data-hasura and give it the hasura server endpoint (assumed to be running at http://localhost:8080) and an optional headers object.

import React from 'react';
import PostIcon from '@material-ui/icons/Book';
import UserIcon from '@material-ui/icons/Group';
import { Admin, Resource, ListGuesser } from 'react-admin';
import hasuraDataProvider from 'ra-data-hasura';
 
import { PostList, PostEdit, PostCreate, PostShow } from './posts';
import { UserList } from './users';
import Dashboard from './Dashboard';
import authProvider from './authProvider';
 
const headers = {'content-type': 'application/json', 'authorization': 'bearer <token>'};
const App = () => (
  <Admin
    dataProvider={hasuraDataProvider('http://localhost:8080', headers)}
    authProvider={authProvider}
    dashboard={Dashboard}
  >
    <Resource
      name="posts"
      icon={PostIcon}
      list={PostList}
      edit={PostEdit}
      create={PostCreate}
      show={PostShow}
    />
    <Resource name="users" icon={UserIcon} list={UserList} />
    <Resource name="comments" list={ListGuesser} />
  </Admin>
);
 
export default App;
 

In case the server is configured with admin secret or auth, configure the appropriate headers and pass it to the provider.

Multiple schemas

To query schemas other than public, you can pass schema to resource in the format <Resource name="schema.table" />.

For example to fetch data from schema test and table author, use the following snippet:

  <Resource name="test.author" list={list} />

Different Primary Keys

Sometimes the table you are querying might have a primary key other than id. react-admin enforces id to be returned in the response by the DataProvider. But you can configure a different primary key column for specific tables using the config object as below:

const config = { 
  'primaryKey': { 
      'tableName': 'primaryKeyColumn', 'tableName2': 'primaryKeyColumn' 
  } 
};

Known Issues

Filter as you type (search) functionality inside tables is not supported right now. It is a work in progress.
