About

It will hide component of route instead of unmout it when the path is not match and restore it when come back. There are a few APIs provided to control the hidden condition of component.

Example：

There is a item list page, click on the items on this page will enter the item detail page. When entering the detail page, item list page will be hidden and it will keep hidden when you are on item detail page. Once back to the list page, the list page will be restored to the last state of leaving.

Features

✅ Fully compatible with react-router-v4, all passed the react-router-v4 unit tests.
🎯 Completely restored to the state of the last time you left (scroll position included).
🔒 Minimally invasive, all you need to do is import LiveRoute.
✌️ Super easy API.

Caveat ⚠️

LiveRoute SHOULD NOT be wrapped by Switch directly, cause Switch only render the first matched child element so that LiveRoute may be skipped directly. You can move LiveRoute from Switch to the outside.
If LiveRoute's parent route is unmounted on current location, then it will also be unmounted . This is determined by the top-down design principle of React. You can use LiveRoute to declares a parent route to solve this problem or stop nestting the router.
In some cases the DOM of LiveRoute will be modified directly and the scroll position will not change when navigation. This is not a problem with react-live-route. You can scroll the screen to the top manually and you may get some help from this article from react-router. By the way, if the scroll position will be restored by LiveRoute, it will come up after the scroll operation in componet of LiveRoute due to the render order of React.

Usage

livePath: string or array

livePath is the path you want to hide the component instead of unmount it. The specific rules of livePath are the same as path props of Route in react-router-v4. You still can use component or render props to render a component.

livePath also can accept an array of string above since 1.2.0. livePath is matched if any string in the array is matched.

LiveRoute will re-render when it come back from a path matching location from the livePath matching location. It will unmount on other unmatched locations.

Example:

The route of List will be rendered normally under /list, and it will be hidden when location change to /user/:id, and it will be unmounted normally when entering other locations.

import LiveRoute from 'react-live-route'

<LiveRoute path="/list" livePath="/user/:id" component={List} />

alwaysLive: bool

alwaysLive is just like livePath. The difference is the component will not be unmount on any other location after the it's first mount.
