Package Exports
- connected-react-router
- connected-react-router/lib/actions
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (connected-react-router) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Connected React Router
A Redux binding for React Router v4
Main features
✨ Synchronize router state with redux store with uni-directional flow (history -> store -> router -> components)
🎁 Support React Router v4
☀️ Support functional component hot reloading while preserving state (with react-hot-reload v3)
🎉 Dispatching history methods (push, replace, go, goBack, goForward) are available for both redux-thunk and redux-saga
⛄ Nested children can access routing state such as current location directly with redux's connect
Installation
Using npm:
$ npm install --save connected-react-router
Or yarn:
$ yarn add connected-react-router
Usage
Step 1
- Create a
history
object. - Wrap the root reducer with
connectRouter
and supply thehistory
object to get a new root reducer. - Use
routerMiddleware(history)
if you want to dispatch history actions (ex. to change URL withpush('/path/to/somewhere')
).
import { createBrowserHistory } from 'history'
import { applyMiddleware, compose, createStore } from 'redux'
import { routerMiddleware, connectRouter } from 'connected-react-router'
const history = createBrowserHistory()
const store = createStore(
connectRouter(history)(rootReducer), // new root reducer with router state
initialState,
compose(
applyMiddleware(
routerMiddleware(history), // for dispatching history actions
// ... other middlewares ...
),
),
)
Step 2
- Wrap your react-router v4 routing with
ConnectedRouter
and passhistory
object as a prop. - Place
ConnectedRouter
as children ofreact-redux
'sProvider
.
import React from 'react'
import ReactDOM from 'react-dom'
import { Provider } from 'react-redux'
import { Match, Miss } from 'react-router' // react-router v4
import { ConnectedRouter } from 'connected-react-router'
...
ReactDOM.render(
<Provider store={store}>
<ConnectedRouter history={history}> { /* place ConnectedRouter under Provider */ }
<div> { /* your usual react-router v4 routing */ }
<Match exactly pattern="/" render={() => (<div>Match</div>)} />
<Miss render={() => (<div>Miss</div>)} />
</div>
</ConnectedRouter>
</Provider>,
document.getElementById('react-root')
)
Now, it's ready to work!

- How to get current URL path
- How to support functional component hot reloading
How to navigate with Redux action
with store.dispatch
import { push } from 'connected-react-router'
store.dispatch(push('/path/to/somewhere'))
in redux thunk
import { push } from 'connected-react-router'
export const login = (username, password) => (dispatch) => {
/* do something before redirection */
dispatch(push('/home'))
}
in redux saga
import { push } from 'connected-react-router'
import { put, call } from 'redux-saga/effects'
export function* login(username, password) {
/* do something before redirection */
yield put(push('/home'))
}
How to get current URL path
The current URL path can be accessed directry from the router state with react-redux
's connect
.
import { connect } from 'react-redux'
const Child = ({ path }) => (
<div>
Child receives path {path}.
</div>
)
const mapStateToProps = state => ({
path: state.router.location.pathname,
})
export default connect(mapStateToProps)(Child)
How to support functional component hot reloading
- Separate main app component to another file.
App.js
import React from 'react'
import { Match, Miss } from 'react-router' /* react-router v4 */
import { ConnectedRouter } from 'connected-react-router'
const App = ({ history }) => ( /* receive history object via props */
<ConnectedRouter history={history}>
<div>
<Match exactly pattern="/" render={() => (<div>Match</div>)} />
<Miss render={() => (<div>Miss</div>)} />
</div>
</ConnectedRouter>
)
export default App
- Wrap the
App
component withAppContainer
fromreact-hot-loader
v3 as a top-level container.
index.js
import React from 'react'
import ReactDOM from 'react-dom'
import { Provider } from 'react-redux'
import { AppContainer } from 'react-hot-loader' /* react-hot-loader v3 */
import App from './App'
...
const renderWithHotReload = (AppComponent) => { // this function will be reused
ReactDOM.render(
<AppContainer> { /* AppContainer for hot reloading v3 */ }
<Provider store={store}>
<AppComponent history={history} /> { /* pass history object as props */ }
</Provider>
</AppContainer>,
document.getElementById('react-root')
)
}
renderWithHotReload(App) // render
- Detect change and re-render with hot reload.
index.js
...
if (module.hot) {
module.hot.accept('./App', () => {
const NextApp = require('./App').default
renderWithHotReload(NextApp)
})
}
Now, when you change any component that App
depends on, it will trigger hot reloading without losing redux state. Thanks react-hot-loader v3!
Build
npm run build
Generated files will be in lib
folder.
Cautions
This is still an experimental project. It relies on several alpha and beta things (i.e. react-hot-loader v3 and react-router v4). Anything can be changed. Bugs are certainly waiting for you to wake them up. Please use it at your own risk.

Connected React Router is based on several awesome people' ideas
- Several parts of Connected React Router is based on react-router-redux v4.
- A PR by @timdorr to make react-router-redux v5 to integrate React Router v4 contains several ideas to drive Connected React Router.
- The ConnectedRouter component is inspired by App component by @cherijs with history synchronization enhancement.
- The idea of uni-directional flow (history -> store -> router -> components) is from a @lourd's comment
