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

yarn

yarn add @formio/react @formio/js

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:

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 to interact with a Form.io server:

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.

Props

Name	Type	Description
initialPage	number	The initial page to fetch.
limit	string	The number of results per page.
dataOrFetchFunction	T[] \| (limit: number, skip: number) => Promise<T[]>	Either the complete set of data to be paginated or a function that returns data. If a function, must support limit and skip and be a stable reference.

Return Value

usePagination returns an object with the following parameters:

Name	Type	Description
data	T[]	The data at the current page.
total	number \| undefined	If available, the total number of documents.
page	number	The current page number.
hasMore	boolean	A value that indicates whether more results are available from the server. Useful when no total document count is available.
nextPage	() => void	A function that moves the data to the next available page.
prevPage	() => void	A function that moves the data to the previous available page.
fetchPage	(page: number) => void	A function that moves the data to a specified page.

Examples

Paginate a set of forms:

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
baseUrl	string	The base url of a Form.io server.
projectUrl	string	The url of a Form.io enterprise project.

Form

A React component wrapper around a Form.io form. Able to take a JSON form definition or a Form.io form URL and render the form in your React application.

Props

Name	Type	Description
`src`	`Webform \| string`	The JSON form definition or the source URL. If a URL, commonly from a form.io server.
`url`	`string`	The url of the form definition. 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 for more details.
`onFormReady`	`(instance: Webform) => void`	A callback function that gets called when the form has rendered. It is useful for accessing the underlying @formio/js Webform instance.
`onSubmit`	`(submission: JSON, saved?: boolean) => void`	A callback function that gets called when the submission has started. If `src` is not a Form.io server URL, this will be the final submit event.
`onCancelSubmit`	`() => void`	A callback function that gets called when the submission has been canceled.
`onSubmitDone`	`(submission: JSON) => void`	A callback function that gets called when the submission has successfully been made to the server. This will only fire if `src` is set to a Form.io server URL.
`onChange`	`(value: any, flags: any, modified: any) => void`	A callback function that gets called when a value in the submission has changed.
`onComponentChange`	`(changed: { instance: Webform; component: Component; value: any; flags: any}) => void`	A callback function that gets called when a specific component changes.
`onError`	`(error: EventError \| false) => void`	A callback function that gets called when an error occurs during submission (e.g. a validation error).
`onRender`	`(param: any) => void`	A callback function that gets called when the form is finished rendering. `param` will depend on the form and display type.
`onCustomEvent`	`(event: { type: string; component: Component; data: JSON; event?: Event; }) => void`	A callback function that is triggered from a button component configured with "Event" type.
`onPrevPage`	`(page: number, submission: JSON) => void`	A callback function for Wizard forms that gets called when the "Previous" button is pressed.
`onNextPage`	`(page: number, submission: JSON) => void`	A callback function for Wizard forms that gets called when the "Next" button is pressed.
`otherEvents`	`[event: string]: (...args: any[]) => void;`	A "catch-all" prop for subscribing to other events (for a complete list, see our documentation).

Examples

Render a simple form from the Form.io SaaS:

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:

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 for details):

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. For this reason, we recommend dynamically importing the Form component using Next.js' dynamic API:

'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. Able to render the form builder in your React application.

Props

Name	Type	Description
`initialForm`	`FormType`	The JSON form definition of the initial form to be rendered in the builder. Oftentimes, this must be a stable reference; otherwise it may destroy and recreate the underlying builder instance and cause unexpected behavior.
`options`	`FormBuilderOptions`	The form builder options. See here for more details.
`onBuilderReady`	`(instance: FormBuilder) => void`	A callback function that gets called when the form builder has rendered. It is useful for accessing the underlying @formio/js FormBuilder instance.
`onChange`	`(form: FormType) => void`	A callback function that gets called when the form being built has changed.
`onSaveComponent`	`(component: Component, original: Component, parent: Component, path: string, index: number, isNew: boolean, originalComponentSchema: Component) => void;`	A callback function that gets called when a component is saved in the builder.
`onEditComponent`	`(component: Component) => void`	A callback function that gets called when a component is edited.
`onUpdateComponent`	`(component: Component) => void`	A callback function that is called when a component is updated.
`onDeleteComponent`	`(component: Component, parent: Component, path: string, index: number) => void`	A callback function that is called when a component is deleted.

Examples

Render a simple form builder with a blank form:

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:

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 for details):

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",
	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 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 />);

`initialForm`	`FormType`	`{ title: '', name: '', path: '', display: 'form' as const, type: 'form' as const, components: [] }`	The form definition of the existing form that is to be modified.
`settingsForm`	`FormType`	`DEFAULT_SETTINGS_FORM`	The form definition for the "settings" form, which defaults to a form that defines the title, name, path, tags, and display of the form being edited.
`settingsFormOptions`	`FormOptions`	`{}`	The options passed to the settings form.
`onSettingsFormReady`	`(instance: Webform) => void`		The `onFormReady` callback for the settings form.
`onBuilderReady`	`(instance: FormioBuilder) => void`		The `onBuilderReady` callback for the form builder.
`builderOptions`	`FormBuilderOptions`	`{}`	The options to be passed to FormBuilder.
`saveFormFn`	`(form: FormType) => Promise<CoreFormType>`		Defaults to using the Form.io SDK to save the form to a Form.io server configured by `<FormioProvider />`.
`onSaveForm`	`(form: FormType) => void`		The callback that is called after `saveFormFn` is called (either the prop or the default). 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:

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

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

Examples

Load a simple submission grid that fetchs forms from a Form.io server (configured via the <FormioProvider /> component):

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

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

root.render(
	<FormioProvider projectUrl="https://examples.form.io">
		<SubmissionGrid formId="57aa1d2a5b7a477b002717fe" />
	</FormioProvider>,
);

Inject your own markup and styling into constituent components:

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

const components: SubmissionTableProps['components'] = {
	Container: ({ children }) => <div className="table-wrap">{children}</div>,
	TableContainer: ({ children }) => (
		<div className="table remember-focus-table">{children}</div>
	),
	TableHeadContainer: ({ children }) => <div>{children}</div>,
	TableHeaderRowContainer: ({ children }) => (
		<div className="trow heading">{children}</div>
	),
	TableHeadCell: ({ children }) => <div className="tcol">{children}</div>,
	TableBodyRowContainer: ({ children, onClick }) => (
		<div className="trow entry" onClick={onClick}>
			{children}
		</div>
	),
	TableBodyContainer: ({ children }) => <div>{children}</div>,
	TableCell: ({ children }) => <div className="tcol">{children}</div>,
	PaginationContainer: ({ children }) => (
		<div className="table-pagination">
			<div className="table-pagination-controls">{children}</div>
		</div>
	),
	PaginationButton: ({ children, isActive, onClick, disabled }) => (
		<a
			className={`pagination-btn${isActive ? ' active' : ''}${disabled ? ' disabled' : ''}`}
			onClick={onClick}
		>
			{children}
		</a>
	),
};

export const MySubmissionGrid = ({ id }: { id: string }) => {
	return (
		<SubmissionGrid
			onSubmissionClick={(id) =>
				console.log(`Submission with id ${id} clicked!`)
			}
			components={components}
			formId={id}
		/>
	);
};

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

root.render(
	<FormioProvider projectUrl="https://examples.form.io">
		<MySubmissionGrid id="57aa1d2a5b7a477b002717fe" />
	</FormioProvider>,
);

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

The auth module is designed to make it easier to login, register and authenticate users within react using the form.io login system.

Reducers

Name	Parameters	Description
`auth`	config: object	Mounts the user and access information to the state tree. Config is not currently used but is a placeholder to make it consistent to the other reducers.

Actions

Name	Parameters	Description
`initAuth`		This is usually used at the start of an app code. It will check the localStorage for an existing user token and if found, log them in and fetch the needed information about the user.
`setUser`	user: object	When a user logs in, this will set the user and fetch the access information for that user. The user object is usually a submission from the login or register form.
`logout`		This action will reset everything to the default state, including removing any localStorage information.

form

The form module is for interacting with a single form.

Reducers

Name	Parameters	Description
`form`	config: object	Mounts the form to the state tree. The config object should contain a name property defining a unique name for the redux state.

Actions

Name	Parameters	Description
`getForm`	name: string, id: string, done: function	Fetch a form from the server. If no id is provided, the name is used as the path. The `done` callback will be called when the action is complete. The first parameter is any errors and the second is the form definition.
`saveForm`	name: string, form: object, done: function	Save a form to the server. It will use the _id property on the form to save it if it exists. Otherwise it will create a new form. The `done` callback will be called when the action is complete. The first parameter is any errors and the second is the form definition.
`deleteForm`	name: string, id: string, done: function	Delete the form on the server with the id.
`resetForm`	Reset this reducer back to its initial state. This is automatically called after delete but can be called other times as well.

Selectors

Name	Parameters	Description
`selectForm`	name: string, state: object	Select the form definition from the state.

forms

The forms module handles multiple forms like a list of forms.

Reducers

Name	Parameters	Description
`forms`	config: object	Mounts the forms to the state tree. The config object should contain a name property defining a unique name for the redux state. The config object can also contain a query property which is added to all requests for forms. For example: {tags: 'common'} would limit the lists of forms to only forms tagged with 'common'.

Actions

Name	Parameters	Description
`getForms`	name: string, page: integer, params: object	Fetch a list of forms from the server. `params` is a query object to filter the forms.
`resetForms`	Reset this reducer back to its initial state. This is automatically called after delete but can be called other times as well.

Selectors

Name	Parameters	Description
`selectForms`	name: string, state: object	Select the list of forms from the state.

submission

The submission module is for interacting with a single submission.

Reducers

Name	Parameters	Description
`submission`	config: object	Mounts the submission to the state tree. The config object should contain a name property defining a unique name for the redux state.

Actions

Name	Parameters	Description
`getSubmission`	name: string, id: string, formId: string, done: function	Fetch a submission from the server. The `done` callback will be called when the action is complete. The first parameter is any errors and the second is the submission.
`saveSubmission`	name: string, submission: object, formId: string, done: function	Save a submission to the server. It will use the _id property on the submission to save it if it exists. Otherwise it will create a new submission. The `done` callback will be called when the action is complete. The first parameter is any errors and the second is the submission.
`deleteSubmission`	name: string, id: string, formId: string, done: function	Delete the submission on the server with the id.
`resetSubmission`	Reset this reducer back to its initial state. This is automatically called after delete but can be called other times as well.

Selectors

Name	Parameters	Description
`selectSubmission`	name: string, state: object	Select the submission data from the state.

submissions

The submissions module handles multiple submissions within a form, like for a list of submissions.

Reducers

Name	Parameters	Description
`submissions`	config: object	Mounts the submissions to the state tree. The config object should contain a name property defining a unique name for the redux state.

Actions

Name	Parameters	Description
`getSubmissions`	name: string, page: integer, params: object, formId: string	Fetch a list of submissions from the server. `params` is a query object to filter the submissions.
`resetSubmissions`	Reset this reducer back to its initial state. This is automatically called after delete but can be called other times as well.

Selectors

Name	Parameters	Description
`selectSubmissions`	name: string, state: object	Select the list of submissions from the state.
