react-confirm

react-confirm is a lightweight library that simplifies the implementation of confirmation dialogs in React applications by offering a Promise-based API that works seamlessly with async/await syntax, similar to window.confirm.

One key feature of react-confirm is that it doesn't provide a specific view or component for the confirmation dialog, allowing you to easily customize the appearance of the dialog to match your application's design.

Motivation

React is a powerful library that allows for reactive rendering based on component state. However, managing temporary states like confirmation dialogs can quickly become complex. The question is: is it worth implementing these states within your app? The answer is not always a clear yes.

What you can do

react-confirm library offers several benefits:

• You can open a dialog component by calling a function without appending it into your React tree. The function returns a promise, allowing you to handle confirmation results with callbacks.
• You can pass arguments to the function and use them inside the dialog component.
• You can retrieve values from the component in the promise.
• The library provides flexibility in designing the dialog. There is no limitation in the type of components you can use, whether it be input forms or multiple buttons. You can even check out the demo site to see examples of how to customize the dialog.

Versions

• React 18+ users should use react-confirm version 0.2.x or 0.3.x
• React <=17 users should stick to react-confirm version 0.1.x

Usage

1. Create your dialog component.
2. Apply confirmable HOC to your component (Optional. See confirmable implementation).
3. Create a function using createConfirmation by passing your confirmable component.
4. Call it!

Create your dialog component and Apply confirmable HOC to your component.

import * as React from 'react';

import Modal from 'react-bootstrap/Modal'
import Button from 'react-bootstrap/Button'

import { confirmable, ConfirmDialog } from 'react-confirm';

export interface Props {
  confirmation?: string;
};

const Confirmation: ConfirmDialog<Props, boolean> = ({show, proceed, confirmation}) => (
  <Dialog onHide={() => proceed(false)} show={show}>
    {confirmation}
    <button onClick={() => proceed(false)}>CANCEL</button>
    <button onClick={() => proceed(true)}>OK</button>
  </Dialog>
);

export default confirmable(Confirmation);

Create a function using createConfirmation

import { createConfirmation } from 'react-confirm';
import YourDialog from './YourDialog';

// create confirm function
export const confirm = createConfirmation(YourDialog);

Call it!

Now, you can show dialog just like window.confirm with async-await. The most common example is onclick handler for submit buttons.

import { confirmWrapper, confirm } from './confirm'

const handleOnClick = async () => {
  if (await confirm({
    confirmation: 'Are you sure?'
  })) {
    console.log('yes');
  } else {
    console.log('no');
  }
}

Using with Context

By default, this library renders the confirmation dialog without appending the component to your app's React component tree. While this can be useful, it may cause issues if you need to consume context in your component. To overcome this problem, you can use the MountPoint component to include your confirmation dialog within your app's tree, enabling it to access context and other data from the app.

Create your own createConfirmation function and MountPoint Component using createConfirmationCreater and createReactTreeMounter.

import { createConfirmationCreater, createReactTreeMounter, createMountPoint } from 'react-confirm';

const mounter = createReactTreeMounter();

export const createConfirmation = createConfirmationCreater(mounter);
export const MountPoint = createMountPoint(mounter);

Put MountPoint into your React tree.

const YourRootComponent = () => {
  return (
    <YourContext.Provider>
      <MountPoint />
      <YourApp />
    </YourContext.Provider>
  )
}

use your createConfirmation as usual.

export const confirm = createConfirmation(YourDialog);

To render the confirmation dialog within the React component tree but in a different part of the DOM, you can pass a DOM element to the createReactTreeMounter function. This will use the createPortal method to render the confirmation dialog in the specified DOM element while keeping it within the React component tree.

const mounter = createReactTreeMounter(document.body);

typescript usage

Below, we present two possible ways to define a confirmation dialog component using react-confirm. You can choose either based on your preference.

const Confirmation1: React.FC<ConfirmDialogProps<Props, Response>> = (props) => (<Dialog></Dialog>)
const Confirmation2: ConfirmDialog<Props, Response> = (props) => (<Dialog></Dialog>)

When defining your dialog component, set both the Props for the dialog and the Response value to be passed when the dialog closes. This will be handy when calling the dialog.
