Postgraphile client for react-admin
Typescript API: https://bowlingx.github.io/ra-postgraphile/
Install
$ yarn add ra-postgraphile / npm install ra-postgraphile --save
Usage
The ra-postgraphile
data provider accepts 2 arguments:
client
- TheApolloClient
instance to use.config
- optional configurationpgDataProvider(client, [config])
The following examples shows the basic usage:
import React, { useEffect, useState } from 'react'
import { Admin, Resource } from 'react-admin'
import { useApolloClient } from '@apollo/react-hooks'
import pgDataProvider from 'ra-postgraphile'
import { PostList, PostEdit, PostCreate } from './posts'
import { CommentList, CommentEdit, CommentCreate } from './posts'
const App = () => {
const [dataProvider, setDataProvider] = useState(null)
const client = useApolloClient()
useEffect(() => {
;(async () => {
const dataProvider = await pgDataProvider(client)
setDataProvider(() => dataProvider)
})()
}, [])
return (
dataProvider && (
<Admin dataProvider={dataProvider} layout={Layout}>
<Resource name="Posts" list={PostList} edit={PostEdit} create={PostCreate} />
<Resource name="Comments" list={CommentList} create={CommentCreate} edit={CommentEdit} />
</Admin>
)
)
}
export default App
Limitations
The project has been tested only with the following plugins enabled on postgraphile
:
There is limited support for the postgis
plugin and not all input/query types are properly mapped.
const PgSimplifyInflectorPlugin = require('@graphile-contrib/pg-simplify-inflector')
const PgConnectionFilterPlugin = require('postgraphile-plugin-connection-filter')
Please see src/__test_utils/QueryRunner.ts for a minimal example setup.
For full-text search capabilities, the following plugin is also required:
const PostGraphileFulltextFilterPlugin = require('postgraphile-plugin-fulltext-filter')
Configuration
You can pass an optional configuration object:
const pgDataProviderConfig: ProviderOptions = {
typeMap: {
YourType: {
expand: true,
},
},
}
typeMap
- allows you to configure complex types and how they should be handled. Please see (src/defaultTypeConfig.ts) for a default mapping. Your config will be merged with the defaults.
TypeConfig options
The following can be configured
| Option | Signature | Description |
| -------------------------- | ---------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- |
| queryValueToInputValue
| (value: any ) => any
| Allows you to map the value if used as an input type for mutations. Some values might not convert 1:1 if returned from the query and used as an input |
| excludeFields
| string[] or ((fieldName: string, queryFetchType: FetchQueryType) => boolean)
| Allows you to exclude certain fields, either by passing an array (e.g. ['field1', 'field2']
) or a function |
| includeFields
| string[] or ((fieldName: string, queryFetchType: FetchQueryType) => boolean)
| Same as exclude fields, but if provided will let you dynamically decide if a field is queried. |
| computeArgumentsForField
| (fieldName: string, args: ReadonlyArray<IntrospectionInputValue> ) => Record< string, any> or null
| Allows you to dynamically provide arguments for a given field |
| expand
| boolean
| If true, will expand this type and query subfields |
Please see (src/types.ts) for detailed types of TypeConfig
.
Apollo client
Both version 2.x
and 3.x
of apollo client are supported (because you provide the instance).
The current 4.x
version of this library depends on apollo-client
2.x
, so
you will get typescript errors. To resolve that you have to cast to any
:
Example:
// ..
// fix for apollo-client v3
const dataProvider = await createDataProvider(client as any /** other options **/)
// ..
Version 5 will depend on @apollo/client
3.x
.
Supported concepts
ra-postgraphile
works on graphql types that are exposed by postgraphile
.
We currently support the following constructs to query data:
Tables
Views
Functions
with custom return type.
Please see here for an example schema.
Primary Keys
react-admin
requires each resource to be identified by a unique id
. If your resource does not have an id
field,
we will use the generated nodeId
from your primaryKey
. All types processed by ra-postgraphile
require a primary key.
Contribution
- Contribution is very welcome :).
- Please create your commit messages based on semantic-release syntax and semantics (e.g. properly mark Breaking changes etc.). This let's us automatically create release notes and releases to NPM.
Development
We are using yarn
for package management.
To run all tests you have to start the dependent postgres container with docker-compose up -d
.
