@noxy/react-dialog v1.2.2

react-dialog

Introduction

react-dialog is a React functional component hook which creates a dialog renderer element and a dialog creation function. The dialog is only a container element and wrapper and does not come with any dialog templates. Child elements added to the dialog component will have access to the DialogInstance object through the DialogContext.

Installation

To install run the following command:

npm install @noxy/react-dialog@latest

Typescript types are already available in the library so no need to get external types.

Usage

The following is an example of how to use the component:

import {useDialog, DialogContext} from "@noxy/react-dialog";
import React, {HTMLProps, useContext} from "react";

function TestComponent(props: HTMLProps<HTMLDivElement>) {
  const [dialog, createDialog] = useDialog();
  
  return (
    <>
      <div>
        <button onClick={onButtonClick}>Hello</button>
      </div>
      {dialog}
    </>
  );
  
  function onButtonClick() {
    createDialog({
      children: <DialogComponent onClose={onDialogClose}/>
    });
  }
  
  function onDialogClose(value: string) {
  
  }
}

function DialogComponent(props: {onClose: (value: string) => void}) {
  const dialog = useContext(DialogContext)
  
  return (
    <div className={"dialog"}>
      World!
      <button onClick={onButtonClick}>Ok</button>
    </div>
  )
  
  function onButtonClick() {
    dialog.close("a value");
  }
}

The useDialog hook takes a namespace as argument. This is the namespace which the dialogs created by the createDialog function will be stored. The dialog renderer supplied by the hook will display only dialogs from that namespace. The default namespace is "global".

Properties

The DialogInstance component inherits all HTMLDivElement properties and applies them directly to the outermost element. This includes the className property for those using CSS modules.

overlay: boolean

Determines if an overlay should be shown behind the dialog, disabling clicking on anything behind the dialog.

Default value: true

dismissible: boolean

Only relevant if overlay is set to true. Determines if the dialog should be able to be dismissed by clicking on the overlay behind the dialog. Dismissing a dialog in this way will trigger the onClose handler.

Default value: true

closeable: boolean

Determines if a close button should be shown inside the dialog that can be clicked to close the dialog.

Default value: true

onClose: callback(dialog: DialogEvent): void

A callback function which is called when the dialog is dismissed or closed, either through the close button, the overlay, or the DialogInstance close method.

interface DialogEvent<V> {
    value: V
    dialog: DialogInstance
}

Default value: undefined
