Overview

Promps user to confirm navigation. A replacement component for the react-router <Prompt/>. Allows for more flexible dialogs.

Note: Navigation away from your site, reload, or closing tab/window will also prompt navigation confirmation when <NavigationPrompt/>'s props.when is truthy. Usually, browsers handle this navigation UX themselves, leading to vanilla alert boxes. Also, many browsers require users to interact with your site before confirming navigation away.

Example Usage

Simplest example:

import NavigationPrompt from 'react-router-navigation-prompt';

import ConfirmNavigationModal from './your-own-code';

<NavigationPrompt when={this.state.shouldConfirmNavigation}>
  {({onConfirm, onCancel}) => (
    <ConfirmNavigationModal when={true} onCancel={onCancel} onConfirm={onConfirm}/>
  )}
</NavigationPrompt>

Complex example:

import NavigationPrompt from 'react-router-navigation-prompt';

import Modal from './your-own-code';

<NavigationPrompt
  beforeConfirm={this.cleanup}
  // Children will be rendered even if props.when is falsey and isActive is false:
  renderIfNotActive={true}
  // Confirm navigation if going to a path that does not start with current path:
  when={(crntLocation, nextLocation) => !nextLocation.pathname.startsWith(crntLocation.pathname)}
>
  {({isActive, onCancel, onConfirm}) => {
    if (isActive) {
      return (
        <Modal show={true}>
          <div>
            <p>Do you really want to leave?</p>
            <button onClick={onCancel}>Cancel</button>
            <button onClick={onConfirm}>Ok</button>
          </div>
        </Modal>
      );
    }
    return (
      <div>This is probably an anti-pattern but ya know...</div>
    );
  }}
</NavigationPrompt>
