Usage:

1. Include the Stack Modals library in your project.
2. Initialize the modal stack.
3. Create and manage modals as needed.

import { StackModals, createModal } from 'stack-modals'

enum ModalName {
    HELLO_MODAL = 'HELLO_MODAL',
    BYE_MODAL = 'BYE_MODAL'
}

type HelloModalProps = {
    title: string;
    subtitle?: string;
}

type ByeModalProps = {
    title: string;
    exitText?: string;
}

/* Initial state with strongly typed values */
const initialState = {
    /* With createModal() util: */
    ...createModal<ModalName.HELLO_MODAL, HelloModalProps>
        (ModalName.HELLO_MODAL, { subtitle: 'Default Subtitle', title: 'Default Title' }),
    /* Without util */
    [ModalName.BYE_MODAL]: {
        title: 'Bye!',
        exitText: ':('
    } as ByeModalProps
}

const { stack, addModal, updateModal, deleteModal, clearModals } = new StackModals(initialState)
/*
* Function addModal returns a key that (modalKey) can be used to:
*  - delete modal from stack, 
*  - search the inside the stack (for getting passed paremetrs)
*  - update the state of the current modal
* */

const modalKey = addModal('MODAL', { title: 'Title' })
/* Update case */
updateModal(modalKey, { title: '', subtitle: 'After update' });
/* Delete case */
deleteModal(modalKey)
/* Search in stack case */
stack.get(modalKey)

    
/* 
* Using the function clearModals(), you can delete all modal windows based on their name. 
* For example: clearModals(ModalName.HELLO_MODAL) 
* shoud remove all windows with name ModalName.HELLO_MODAL from the stack
* */
clearModals(ModalName.HELLO_MODAL)

Usage with ReactJS:

import { StackModals, createModal } from 'stack-modals'
import {useEffect, useState, FC} from "react";
import type {ModalNameType, ModalScheme, OpenModalFnResult} from "stack-modals/types";


/* All modal names enum */
enum ModalName {
    CONFIRM = 'CONFIRM'
}

/* Specific modal props */
type ConfirmModalProps = {
    title: string;
    subtitle?: string;
}

/* All modal scheme based on ModalScheme*/
type GlobalModalState = {
    [ModalName.CONFIRM]: ConfirmModalProps
}

/* Default modal props (for passing inside the stack render */
export type BaseModalProps<S extends ModalScheme = GlobalModalState> = {
    modalKey: OpenModalFnResult<S>;
    modalName: ModalNameType<S>;
    onClose: (key: OpenModalFnResult<S>) => void;
};

const { stack, addModal, updateModal, addTrap, getModalName, deleteModal, clearModals } = new StackModals({
    ...createModal<'CONFIRM', ConfirmModalProps>('CONFIRM', { subtitle: 'Default Subtitle', title: 'Default Title' }),
})

// file modals/ConfirmModal.tsx
export const ConfirmModal: FC<ConfirmModalProps & BaseModalProps> = ({  modalKey, modalName, onClose, handleComplete, handleCancel, subtitle, title}) => {
    return (
        <YourCustomModalComponent modalName={modalName} modalKey={modalKey} onClose={onClose}>
            <h3>Modal key: {modalKey}</h3>
            <p>{title}</p>
            <caption>{subtitle}</caption>
            <button onClick={() => onClose(modalKey)}>close</button>
        </YourCustomModalComponent>
    )
}

// file modules/ModalModule.tsx (can be inserted in the top level of our App)
export const ModalModule: FC = () => {
    const [openedModals, setOpenedModals] = useState(stack)
    useEffect(() => {
        const handler = (newStack: typeof stack) => {
            setOpenedModals(() => new Map(newStack))
        }

        addTrap("add", handler)
        addTrap("update", handler)
        addTrap("delete", handler)
    }, []);

    return (
        <div>
            {Array.from(openedModals.entries()).map(([key, props]) => {
                const name = getModalName(key)

                const createDefaultProps = <T extends keyof GlobalModalState>(modalName: T) => ({
                    key,
                    modalName,
                    modalKey: key,
                    onClose: deleteModal,
                    ...(props as GlobalModalState[T])
                });

                switch (name) {
                    case ModalName.CONFIRM:
                        return <ConfirmModal {...createDefaultProps(ModalName.CONFIRM)} />
                    default:
                        return null
                }
            })}
        </div>
    )
}

// file hooks/useModal.tsx
export const useModal = () => {
    return {
        openModal: addModal,
        closeModal: deleteModal,
        updateModal,
    }
}
