Overview

Promps user to confirm navigation. A replacement component for the react-router <Prompt/> (this still uses react-router to work). Allows for more flexible dialogs.

Note: Currently tested using only react-router's BrowserHistory. HashHistory has issues: https://github.com/ZacharyRSmith/react-router-navigation-prompt/issues/36

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

Motivation: https://github.com/ReactTraining/react-router/issues/4635

Adapted from: https://gist.github.com/bummzack/a586533607ece482475e0c211790dd50

Demo

A visual example of <Prompt /> vs the package in action:

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={(clb)=>this.cleanup(clb)} //call the callback function when finished cleaning up
  // 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 || !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>;
