react-use-hook-modal

react-use-hook-modal is a headless React Hook library designed to declaratively manage modals without including any UI components. This allows developers to fully control how their modals look and behave by integrating with any UI framework or custom modal system.

Features

• 🎯 Declaratively manage modals in your React application.
• 🛠️ Headless implementation with no UI dependencies.
• ⚙️ Easily integrate with any UI framework or custom modal system.
• 🎨 Fully customizable modal behavior (animations, transitions, etc.).

Examples

You can explore the full list of examples, including live CodeSandbox links, in the example list. These examples demonstrate how to integrate react-use-hook-modal with popular UI libraries like Material UI, Bootstrap, Chakra UI, and even custom modal setups. Try different use cases directly in your browser.

Installation

Install the package with your package manager of choice:

npm

npm install react-use-hook-modal

yarn

yarn add react-use-hook-modal

pnpm

pnpm add react-use-hook-modal

Getting set up

To start using react-use-hook-modal, wrap your application with the ModalProvider.

import { ModalProvider } from 'react-use-hook-modal';

export default App = ({ children }) {
  return (
    <ModalProvider>
      {children}
    </ModalProvider>
  );
}

Basic Usage

To open a modal, you can use the useModal hook as shown below.

import { useModal } from 'react-use-hook-modal';
import MyModalComponent from './MyModalComponent';

const MyComponent = () => {
  const { open, close } = useModal(MyModalComponent);

  const onOpenModal = useCallback(() => {
    open({
      onClose: close,
      onConfirm: () => {
        console.log('Confirmed');
        close();
      },
    });
  }, []);

  return <button onClick={onOpenModal}>Open Modal</button>;
};

You can integrate react-use-hook-modal with libraries like react-transition-group to add animations to your modals:

import { ModalProvider } from 'react-use-hook-modal';
import { TransitionGroup } from 'react-transition-group';

const App = ({ children }) => {
  return <ModalProvider container={TransitionGroup}>{children}</ModalProvider>;
};

API Reference

ModalProvider

Prop	Type	Default	Description
children	React.ReactNode	Required	The child elements rendered inside the ModalProvider. Typically, this is your application that interacts with the modals.
container	React.ComponentType	React.Fragment	Optional custom container component for rendering modals. Use this to define a custom container, allowing you to integrate modal animations with libraries like React Transition Group.
clearTime	number	3000 (3 seconds)	The time in milliseconds before a modal is fully removed from the internal state (modals) after closing. This ensures that any exit animations are fully displayed before the modal is removed from the state.
onAfterOpen	(modal: ModalState) => void	undefined	A callback function triggered immediately after any modal is opened. It provides the state of the modal that was just opened. This can be useful for setting focus or starting animations based on the opened modal.
onAfterClose	(modal: ModalState) => void	undefined	A callback function triggered immediately after any modal is closed. It provides the state of the modal that was just closed, allowing for cleanup tasks or triggering actions based on the closed modal's state.

useModal

useModal is a custom hook designed to manage the opening and closing of modals in a React application. It takes a modal component as input and returns two functions: open and close, which can be used to control the modal's visibility.

Parameter	Type	Description
Component	React.ComponentType<TProps>	The modal component to be rendered. This component should have an isOpen prop that controls its visibility.

Returns:

The useModal hook returns the following functions:

Return Value	Type	Description
open	(props: Omit<TProps, 'isOpen'>, options?: OpenModalOptions) => void (if required props exist) (props?: Omit<TProps, 'isOpen'>, options?: OpenModalOptions) => void (if all props are optional)	Opens the modal. If the modal component has required props, those props must be provided. If all props are optional, open can be called without any props. Additionally, you can pass options such as key and portalTarget.
close	(key?: string | number) => void	Closes the modal. Optionally, a modal key can be passed to close a specific modal instance.
key	string | number	A unique identifier for the modal. It is rarely needed, as most interactions rely on open and close. However, it can be useful in specific cases where you need to track or manage a particular modal's state manually. Note: If you provide a custom key when opening a modal, it will be different from the key returned by useModal.

OpenModalOptions

The OpenModalOptions is an optional parameter for the open function returned by useModal. It allows users to customize the behavior of the modal when opening.

Option	Type	Description
key	string | number	(Optional) A unique key for identifying the modal instance. Useful when managing multiple modals simultaneously.
portalTarget	HTMLElement	(Optional) The DOM element where the modal will be rendered. Useful when you want to render the modal in a specific container or portal.

useModalsState

useModalsState is a custom hook designed to access the current state of all modals in your application.

Returns:

The useModalsState hook returns the current state of modals.

Return Value	Type	Description
modals	Array<ModalObject>	Each modal object contains information about the modal, such as the component, its props, and a unique key.

useClearModals

The useClearModals is a custom hook that provides a function to close all open modals in the application.

Returns:

The useClearModals hook returns an object containing the clearModals function.

Return Value	Type	Description
clearModals	() => void	Closes all currently open modals by setting their isOpen property to false. Any modal that remains unopened before clearTime elapses will be removed from the state after the specified clearTime.

Note: If a modal is reopened before clearTime elapses, it will remain in the state, and only modals that are fully closed during the clearTime period will be removed.
