# JSON Forms - More Forms. Less Code

*Complex forms in the blink of an eye*

JSON Forms eliminates the tedious task of writing fully-featured forms by hand by leveraging the capabilities of JSON, JSON Schema and Javascript.

## React Package

This is the JSON Forms React package which provides the necessary bindings for React. It uses [JSON Forms Core](https://github.com/eclipsesource/jsonforms/blob/master/packages/core).

You can combine the react package with any react-based renderer set you want, for example the [Material Renderers](https://github.com/eclipsesource/jsonforms/blob/master/packages/material-renderers) or the [Vanilla Renderers](https://github.com/eclipsesource/jsonforms/blob/master/packages/vanilla-renderers).

See the official [documentation](https://jsonforms.io/) and the JSON Forms React [seed repository](https://github.com/eclipsesource/jsonforms-react-seed) for examples on how to integrate JSON Forms with your application.

Check <https://www.npmjs.com/search?q=%40jsonforms> for all published JSON Forms packages.

### Usage

Use the `JsonForms` component to render a form for your data.

Mandatory props:

* `data: any` - the data to show
* `renderers: JsonFormsRendererRegistryEntry[]` - the React renderer set to use

Optional props:

* `schema: JsonSchema` - the data schema for the given data. Will be generated when not given.
* `uischema: UISchemaElement` - the UI schema for the given data schema. Will be generated when not given.
* `cells: JsonFormsCellRendererRegistryEntry[]` - the React cell renderer set to use
* `config: any` - form-wide options. May contain default ui schema options.
* `readonly: boolean` - whether all controls shall be readonly.
* `uischemas: JsonFormsUiSchemaEntry[]` - registry for dynamic ui schema dispatching
* `validationMode: 'ValidateAndShow' | 'ValidateAndHide' | 'NoValidation'` - the validation mode for the form
* `ajv: AJV` - custom Ajv instance for the form
* `onChange` - callback which is called on each data change, containing the updated data and the validation result.

Example:

```ts
import React, { useState } from 'react';
import {
  materialRenderers,
  materialCells
} from '@jsonforms/material-renderers';
import { JsonForms } from '@jsonforms/react';

const schema = {
  type: 'object',
  properties: {
    name: {
      type: 'string',
      minLength: 1
    },
    done: {
      type: 'boolean'
    },
    due_date: {
      type: 'string',
      format: 'date'
    },
    recurrence: {
      type: 'string',
      enum: ['Never', 'Daily', 'Weekly', 'Monthly']
    }
  },
  required: ['name', 'due_date']
};
const uischema = {
  type: 'VerticalLayout',
  elements: [
    {
      type: 'Control',
      label: false,
      scope: '#/properties/done' // Arrays are acceptable too: ['#', 'properties', 'done']
                                 // (specially desined for complex paths that include special
                                 // characters)
    },
    {
      type: 'Control',
      scope: '#/properties/name' // OR: ['#', 'properties', 'name']
    },
    {
      type: 'HorizontalLayout',
      elements: [
        {
          type: 'Control',
          scope: '#/properties/due_date'
        },
        {
          type: 'Control',
          scope: '#/properties/recurrence'
        }
      ]
    }
  ]
};
const initialData = {};
function App() {
  const [data, setData] = useState(initialData);
  return (
    <JsonForms
      schema={schema}
      uischema={uischema}
      data={data}
      renderers={materialRenderers}
      cells={materialCells}
      onChange={({ data, _errors }) => setData(data)}
    />
  );
}
```
