Example Usage



Prompts 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:**

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.

Note: If you pass a function to props.when, then make sure to check if nextLocation is defined before trying to use it.

**Note: Just like react-router's <Prompt/>, this component does not work with multiple BrowserHistorys: **

Below is a gif of <Prompt /> and a gif of <NavigationPrompt />, with links to sandboxes to try them yourself:

This gif shows react-router's <Prompt />, which relies on the browser's alert boxes. You can try it here

Example Usage

Simplest example:

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

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

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

Complex example:

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

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

  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:
  // 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}>
            <p>Do you really want to leave?</p>
            <button onClick={onCancel}>Cancel</button>
            <button onClick={onConfirm}>Ok</button>
    return <div>This is probably an anti-pattern but ya know...</div>;
