Description: React renderer for form.io forms.
Author: Randall Knutson
Latest version: 6.2.0

# @formio/react

A [React](http://facebook.github.io/react/) library for rendering out forms based on the [Form.io](https://www.form.io) platform.

## Install

### npm

```bash
npm install @formio/react --save
npm install @formio/js --save
```

### yarn

```bash
yarn add @formio/react @formio/js
```

## Usage with Vite (Note: When using frameworks like Next.js or Create React App, no extra Vite configuration is necessary)

When using @formio/react in a project built with Vite (especially for React 18 and 19), make sure you install the @vitejs/plugin-react package and configure it in your vite.config.js file.

Install Vite React Plugin

```bash
yarn add --dev @vitejs/plugin-react
```

In your vite.config.js, add the React plugin:

```bash
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';

export default defineConfig({
  plugins: [react()],
});
```

## Hooks

### useFormioContext

A hook to supply global Formio contextual values to your React components. **Components that call `useFormioContext` must be children of a `<FormioProvider />` component.**

#### Return Value

`useFormioContext` returns an object with the following parameters:

| Name            | Type          | Description                                                                                                                            |
| --------------- | ------------- | -------------------------------------------------------------------------------------------------------------------------------------- |
| Formio          | typeof Formio | The global Formio object. Useful for various static methods as well as SDK functions that are exposed when the `new` operator is used. |
| baseUrl         | string        | The base url for a Form.io server.                                                                                                     |
| projectUrl      | string        | The base url for a Form.io enterprise project.                                                                                         |
| logout          | () => void    | A convenience method to logout of a Form.io session by invalidating the token and removing it from local storage.                      |
| token           | string        | The Form.io JWT-token (if the user is authenticated).                                                                                  |
| isAuthenticated | boolean       | A convenience value that is toggled when logging in or out of a Form.io session.                                                       |

#### Examples

Use the authentication context provided by `useFormioContext` to evaluate the Form.io authentication of a user:

```tsx
import { createRoot } from 'react-dom/client';
import { useFormioContext, FormGrid, FormioProvider } from '@formio/react';

const App = () => {
	const { isAuthenticated } = useFormioContext();

	return isAuthenticated ? (
		<Router>
			<Route path="/form">
				<FormGrid
					formQuery={{ type: 'form' }}
					onFormClick={(id) => setLocation(`/form/${id}`)}
				/>
			</Route>
			<Route path="/resource">
				<FormGrid
					formQuery={{ type: 'resource' }}
					onFormClick={(id) => setLocation(`/resource/${id}`)}
				/>
			</Route>
		</Router>
	) : (
		<Redirect to="/login" />
	);
};

const domNode = document.getElementById('root');
const root = createRoot(domNode);
root.render(
	<FormioProvider projectUrl="https://examples.form.io">
		<App />
	</FormioProvider>,
);
```

Use the [Form.io SDK](https://help.form.io/developers/javascript-development/javascript-sdk) to interact with a Form.io server:

```tsx
import { createRoot } from 'react-dom/client';
import { useEffect, useState } from 'react';
import {
	useFormioContext,
	FormioProvider,
	FormType,
	Form,
} from '@formio/react';

const FormsByUser = ({ userId }: { userId: string }) => {
	const { Formio, projectUrl } = useFormioContext();
	const [forms, setForms] = useState<FormType[]>([]);

	useEffect(() => {
		const fetchForms = async () => {
			const formio = new Formio(projectUrl);
			try {
				const forms = await formio.loadForms({
					params: { type: 'form', owner: userId },
				});
				setForms(forms);
			} catch (err) {
				console.log(
					`Error while loading forms for user ${userId}:`,
					err,
				);
			}
		};
		fetchForms();
	}, [Formio, projectUrl, userId]);

	return forms.map(function (form) {
		return (
			<>
				<Form src={form} />
				<div style={{ marginBottom: '10px' }} />
			</>
		);
	});
};

const domNode = document.getElementById('root');
const root = createRoot(domNode);
const root = createRoot();
root.render(
	<FormioProvider projectUrl="https://examples.form.io">
		<App />
	</FormioProvider>,
);
```

### usePagination

A hook to supply limit/skip server pagination data and methods to your React components. **Components that call `usePagination` must be children of a `<FormioProvider />` component.**

#### Examples

Paginate a set of forms:

```tsx
import { createRoot } from 'react-dom/client';
import { useCallback } from 'react';
import {
	useFormioContext,
	FormioProvider,
	FormType,
	Form,
} from '@formio/react';

const FormsByUser = ({ userId }: { userId: string }) => {
	const { Formio, projectUrl } = useFormioContext();
	const fetchFunction = useCallback(
		(limit: number, skip: number) => {
			const formio = new Formio(`${projectUrl}/form`);
			return formio.loadForms({ params: { type: 'form', limit, skip } });
		},
		[Formio, projectUrl],
	);
	const { data, page, nextPage, prevPage, hasMore } = usePagination<FormType>(
		1,
		10,
		fetchFunction,
	);

	return (
		<div>
			<div>
				{data.map((form) => (
					<>
						<Form src={form} />
						<div style={{ marginBottom: '10px' }} />
					</>
				))}
			</div>
			<ul>
				<li
					onClick={prevPage}
					className={`${page === 1 ? 'disabled' : ''}`}
				>
					Prev
				</li>
				<li
					onClick={nextPage}
					className={`${hasMore ? '' : 'disabled'}`}
				>
					Next
				</li>
			</ul>
		</div>
	);
};

const domNode = document.getElementById('root');
const root = createRoot(domNode);
const root = createRoot();
root.render(
	<FormioProvider projectUrl="https://examples.form.io">
		<App />
	</FormioProvider>,
);
```

## Components

### FormioProvider

A React context provider component that is required when using some hooks and components from this library.

#### Props

| Name       | Type   | Description                              |
| ---------- | ------ | ---------------------------------------- |
| Formio     | object | The Formio object to be used.            |
| baseUrl    | string | The base url of a Form.io server.        |
| projectUrl | string | The url of a Form.io enterprise project. |

#### Examples

Render a simple form from your self hosted Form.io deployment:

```JSX
import { createRoot } from 'react-dom/client';
import { Form, FormioProvider } from '@formio/react';

const domNode = document.getElementById('root');
const root = createRoot(domNode);

root.render(
  <FormioProvider baseUrl="https://myformiodeployment.example.com/" projectUrl="https://myformiodeployment.example.com/myproject">
    <Form src="https://myformiodeployment.example.com/myproject/myexampleform" />
  </FormioProvider>
);
```

Extend the Formio object to use external modules:

```JSX
import { createRoot } from 'react-dom/client';
import { Form, FormioProvider } from '@formio/react';
import { Formio } from '@formio/js';
import premium from '@formio/premium';

const domNode = document.getElementById('root');
const root = createRoot(domNode);

Formio.use(premium);
root.render(
  <FormioProvider Formio={Formio}>
    <Form src="https://myproject.form.io/myformwithpremiumcomponents" />
  </FormioProvider>
);
```

### Form

A React component wrapper around [a Form.io form](https://help.form.io/developers/form-development/form-renderer#introduction). Able to take a JSON form definition or a Form.io form URL and render the form in your React application.

#### Props

| Name                | Type                                                                                    | Default | Description                                                                                                                                                                                                                                                                                                                             |
| ------------------- | --------------------------------------------------------------------------------------- | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `src`               | `Webform \| string`                                                                     |         | The JSON form definition or the source URL. If a URL, commonly from a form.io server.                                                                                                                                                                                                                                                   |

Used in conjunction with a JSON form definition passed to `src`, this is used for file upload, OAuth, and other components or actions that need to know the URL of the Form.io form for further processing. The form will not be loaded from this url and the submission will not be saved here either. |
| `submission`        | `JSON`                                                                                  |         | Submission data to fill the form. You can either load a previous submission or create a submission with some pre-filled data. If you do not provide a submissions the form will initialize an empty submission using default values from the form.                                                                                      |
| `options`           | `FormOptions`                                                                           |         | The form options. See [here](https://help.form.io/developers/form-development/form-renderer#form-renderer-options) for more details.                                                                                                                                                                                                    |

#### Examples

Render a simple form from the Form.io SaaS:

```JSX
import { createRoot } from 'react-dom/client';
import { Form } from '@formio/react';

const domNode = document.getElementById('root');
const root = createRoot(domNode);

root.render(
	<Form src="https://example.form.io/example" onSubmit={console.log} />,
);
```

Render a simple form from a JSON form definition:

```JSX
import { createRoot } from 'react-dom/client';
import { Form } from '@formio/react';

const domNode = document.getElementById('root');
const root = createRoot(domNode);

const formDefinition = {
	type: "form",
	display: "form",
	components: [
		{
			type: "textfield"
			key: "firstName",
			label: "First Name",
			input: true,
		},
		{
			type: "textfield"
			key: "firstName",
			label: "First Name",
			input: true,
		},
		{
			type: "button",
			key: "submit",
			label: "Submit",
			input: true
		}
	]
}

root.render(<Form src={formDefinition} />);
```

Access the underlying form instance (see [here](https://help.form.io/developers/form-development/form-renderer#form-properties) for details):

```JSX
import { useRef } from 'react';
import { createRoot } from 'react-dom/client';
import { Form } from '@formio/react';

const domNode = document.getElementById('root');
const root = createRoot(domNode);

const formDefinition = {
	type: "form",
	display: "form",
	components: [
		{
			type: "textfield"
			key: "firstName",
			label: "First Name",
			input: true,
		},
		{
			type: "textfield"
			key: "firstName",
			label: "First Name",
			input: true,
		},
		{
			type: "button",
			key: "submit",
			label: "Submit",
			input: true
		}
	]
}

const App = () => {
	const formInstance = useRef(null);

	const handleFormReady = (instance) => {
		formInstance.current = instance;
	}

	const handleClick = () => {
		if (!formInstance.current) {
			console.log("Our form isn't quite ready yet.");
			return;
		}
		formInstance.current.getComponent('firstName')?.setValue('John');
		formInstance.current.getComponent('lastName')?.setValue('Smith');
	}

	return (
		<div>
			<Form src={formDefinition} onFormReady={handleFormReady} />
			<button type="button" onClick={handleClick}>Set Names</button>
		</div>
	);
}

root.render(<App />);
```

#### Usage in Next.js

A number of dependencies in the `@formio/js` rely on web APIs and browser-specific globals like `window`. Because Next.js includes a server-side rendering stage, this makes it difficult to import the Form component directly, even when used in [client components](https://nextjs.org/docs/app/building-your-application/rendering/client-components). For this reason, we recommend dynamically importing the Form component using Next.js' `dynamic` API:

```tsx
'use client';
import dynamic from 'next/dynamic';
import { Webform } from '@formio/js';

const Form = dynamic(
	() => import('@formio/react').then((module) => module.Form),
	{ ssr: false },
);

export default function Home() {
	const formInstance = useRef<Webform | null>(null);

	const handleClick = () => {
		if (!formInstance.current) {
			console.log("Our form isn't quite ready yet.");
			return;
		}
		formInstance.current.getComponent('firstName')?.setValue('John');
		formInstance.current.getComponent('lastName')?.setValue('Smith');
	};

	return (
		<main className={styles.main}>
			<Form
				form="https://examples.form.io/example"
				onFormReady={(instance) => {
					formInstance.current = instance;
				}}
			/>
			<button onClick={handleClick}>Set Names</button>
		</main>
	);
}
```

### FormBuilder

A React component wrapper around [a Form.io form builder](https://help.form.io/developers/form-development/form-builder). Able to render the form builder in your React application.

#### Examples

Render a simple form builder with a blank form:

```JSX
import { createRoot } from 'react-dom/client';
import { FormBuilder } from '@formio/react';

const domNode = document.getElementById('root');
const root = createRoot(domNode);

root.render(
	<FormBuilder />,
);
```

Render a builder with an initial form definition:

```JSX
import { createRoot } from 'react-dom/client';
import { FormBuilder } from '@formio/react';

const domNode = document.getElementById('root');
const root = createRoot(domNode);

const formDefinition = {
	display: "form",
	components: [
		{
			type: "textfield"
			key: "firstName",
			label: "First Name",
			input: true,
		},
		{
			type: "textfield"
			key: "firstName",
			label: "First Name",
			input: true,
		},
		{
			type: "button",
			key: "submit",
			label: "Submit",
			input: true
		}
	]
}

root.render(<FormBuilder form={formDefinition} />);
```

Access the underlying form builder instance (see [here](https://help.form.io/developers/form-development/form-builder#form-builder-sdk) for details):

```JSX
import { useRef } from 'react';
import { createRoot } from 'react-dom/client';
import { FormBuilder } from '@formio/react';

const domNode = document.getElementById('root');
const root = createRoot(domNode);

const formDefinition = {
	display: "form",

		},
		{
			type: "textfield"
			key: "firstName",
			label: "First Name",
			input: true,
		},
		{
			type: "button",
			key: "submit",
			label: "Submit",
			input: true
		}
	]
}

const App = () => {
	const formBuilderInstance = useRef(null);

	const handleFormReady = (instance) => {
		formBuilderInstance.current = instance;
	}

	const handleClick = () => {
		if (!formBuilderInstance.current) {
			console.log("Our form isn't quite ready yet.");
			return;
		}
		console.log("Here's our builder instance:", formBuilderInstance.current);
	}

	return (
		<div>
			<Form src={formDefinition} onFormReady={handleFormReady} />
			<button type="button" onClick={handleClick}>Log Our Builder</button>
		</div>
	);
}

root.render(<App />);
```

### FormEdit

The FormEdit component wraps the FormBuilder component and adds a settings form, enabling direct interaction with forms to and from a Form.io server. **The `FormEdit` component must be a child of a `<FormioProvider />` component.**

An optional function that replaces the default behavior of saving the form to a Form.io server. |

#### Styling

`FormEdit` takes a `components` prop that contains each "element" of the `FormEdit` component, allowing you to inject your own markup and styling. Here is its type:

```ts
type ComponentProp<T = object> = (props: T) => JSX.Element;
type Components = {
	Container?: ComponentProp<{ children: ReactNode }>;
	SettingsFormContainer?: ComponentProp<{ children: ReactNode }>;
	BuilderContainer?: ComponentProp<{ children: ReactNode }>;
	SaveButtonContainer?: ComponentProp<{ children: ReactNode }>;
	SaveButton?: ComponentProp<{
		onClick: () => void;
	}>;
};
```

#### Examples

Load a simple `FormEdit` component that loads a form from a Form.io server:

```tsx
import { createRoot } from 'react-dom/client';
import { useState, useEffect } from 'react';
import {
	FormGrid,
	FormioProvider,
	useFormioContext,
	FormType,
} from '@formio/react';

const App = () => {
	const { Formio, projectUrl } = useFormioContext();
	const [form, setForm] = useState<FormType | undefined>();

	useEffect(() => {
		const fetchForm = async () => {
			try {
				const formio = new Formio(`${projectUrl}/example`);
				const form = await formio.loadForm();
				setForm(form);
			} catch (err) {
				console.log('Error while fetching form:', err);
			}
		};
	}, [Formio, projectUrl]);

	return form ? (
		<FormEdit
			initialForm={form}
			onSaveForm={() => console.log('Form saved to my Form.io server!')}
		/>
	) : null;
};
const domNode = document.getElementById('root');
const root = createRoot(domNode);

root.render(
	<FormioProvider projectUrl="https://examples.form.io">
		<App />
	</FormioProvider>,
);
```

Inject your own markup and styling into constituent components:

```tsx
import { createRoot } from 'react-dom/client';
import { useState, useEffect } from 'react';
import {
	FormEdit,
	FormioProvider,
	useFormioContext,
	FormType,
} from '@formio/react';

const App = ({ name }: { name: string }) => {
	const { Formio, projectUrl } = useFormioContext();
	const [form, setForm] = useState<FormType | undefined>();

	useEffect(() => {
		const fetchForm = async () => {
			try {
				const formio = new Formio(`${projectUrl}/example`);
				const form = await formio.loadForm();
				setForm(form);
			} catch (err) {
				console.log('Error while fetching form:', err);
			}
		};
	}, [Formio, projectUrl]);

	return form ? (
		<FormEdit
			initialForm={form}
			onSaveForm={() => console.log('Form saved to my Form.io server!')}
			components={{
				SaveButtonContainer: ({ children }) => (
					<div
						className="save-form-bar button-wrap"
						style={{ justifyContent: 'end' }}
					>
						{children}
					</div>
				),
				SaveButton: ({ onClick }) => (
					<button className="button save-form" onClick={onClick}>
						Save {name}
					</button>
				),
			}}
		/>
	) : null;
};
const domNode = document.getElementById('root');
const root = createRoot(domNode);

root.render(
	<FormioProvider projectUrl="https://examples.form.io">
		<App name="Form" />
	</FormioProvider>,
);
```

### FormGrid

The FormGrid component can be used to render a list of forms with a set of actions on each row. **The `FormGrid` component must be a child of a `<FormioProvider />` component.**

#### Props

| Name          | Type                               | Default           | Description                                                                                                                                                                                                                      |

| `actions`     | `Action[]`                         | `DEFAULT_ACTIONS` | An array of actions that correspond to buttons on each form grid row. Defaults to an Edit action (which will call the `onFormClick` function prop) and a Delete action (which will use the Form.io SDK to soft delete the form). |
| `forms`       | `FormType[]`                       |                   | If you'd like to manage fetching yourself, you can pass an array of forms to `FormGrid`.                                                                                                                                         |
| `formQuery`   | `Record<string, JSON>`             | `{}`              | If you don't pass the `forms` prop, `FormGrid` will use the Form.io SDK to fetch forms based on the `formQuery` prop.                                                                                                            |
| `onFormClick` | `(id: string) => void`             |                   | A callback function called when the `FormNameContainer` is clicked.                                                                                                                                                              |

		<SubmissionGrid formId="57aa1d2a5b7a477b002717fe" />
	</FormioProvider>,
);
```

Inject your own markup and styling into constituent components:

```tsx
import { SubmissionGridProps, SubmissionGrid } from '@formio/react';
import { createRoot } from 'react-dom/client';

const components: SubmissionTableProps['components'] = {
	Container: ({ children }) => <div className="table-wrap">{children}</div>,

```

## Modules

Modules contain Redux actions, reducers, constants and selectors to simplify the API requests made for form.io forms. Reducers, actions and selectors all have names. This provides namespaces so the same actions and reducers can be re-used within the same redux state.

### root

The root module is the container for things shared by other modules such as the selectRoot selector.

#### Selectors

| Name             | Parameters                  | Description                             |
| ---------------- | --------------------------- | --------------------------------------- |
| `selectRoot`     | name: string, state: object | Returns the state for a namespace.      |
| `selectError`    | name: string, state: object | Returns any errors for a namespace.     |
| `selectIsActive` | name: string, state: object | Returns isActive state for a namespace. |

### auth
