<ApolloForm>

Build React forms based on GraphQL APIs.

The library is currently under active rewriting, please see this ticket for updates

To get started more easily, please read Getting started: build a GraphQL Form in 5 minutes

Pre-requisites

• apollo-codegen (globally)
• react@^15
• react-apollo@^15

Optionally

• typescript@^2.8.4

Installation

Install package

• install yarn add react-apollo-form

Add script to your project

• add to your package.json, at the scripts section :

{
    "scripts": {
        "react-apollo-form": "react-apollo-form fetch-mutations <graphql_endpoint> <outpurDir>"
    }
}

This script will generated 3 files needed by <ApolloForm>:

• schema.json (GraphQL Introspection Query result as JSON)
• mutations.d.ts (all available mutations names as TypeScript type definition)
• apollo-form-json-schema.json (GraphQL Schema as JSON Schema)

Tips: you can change the output directory of theses with the second argument or -o option

Usage

Once the files generated, we can setup a Form.

import * as React from 'react';
import gql from 'graphql-tag';
import { configure } from 'react-apollo-form';
import { client } from './apollo';
import { applicationFormTheme } from './core/forms/themes/application';


const jsonSchema = require('./core/apollo-form-json-schema.json');

export const ApplicationForm = configure<ApolloFormMutationNames>({
    // tslint:disable-next-line:no-any
    client: client as any,
    jsonSchema,
    theme: applicationFormTheme
});

<ApplicationForm
    config={{
        mutation: {
            name: 'create_todo',
            document: gql`mutation {...}`
        }
    }}
    data={{}}
/>

API

ApolloForm is based on the amazing Mozilla library react-jsonschema-form. Most of the questions regarding JSON Schema, validations or rendering are in react-jsonschema-form documentation

The following subjects are specific to ApolloForm:

• configure your "Form component"
• Theming
• Build a form without mutation
• Add a form specific Widget (outside a theme)
• Conditional fields
• Form rendering customisation
• Add RegExp constraint to a field
• Error messages customization

Q&A

• Can I make ApolloForm works with many GraphQL endpoints?

Yes, just setup multiple scripts in your project package.json with one output folder per endpoint, then just configure a "component form" for each endpoint

• Where can I find some documentation about widgets, fields or theming in general?

Please take a look at the react-jsonschema-form documentation that will answers 90% of the rendering questions. If not, please take a look at Theming

Architecture

General

The idea is to build forms using mutations from the GraphQL API.

ApolloForm is "just" a wrapper around react-jsonschema-form.

It brings some "embed" features:

• JSON schema generation from GraphQL Schema
• conditionals forms
• form rendering customisation with render props
• build JSON Schema with functions (with functional-json-schema)

GraphQL to JSON Schema
