Readme
Breaking change in v5.0.0! Please read How to migrate from v4 to v5/v6.
v6.0.0 requires React v16.4.0 and React Redux v6.0 / v7.0.
Connected React Router
A Redux binding for React Router v4 and v5
Main features
:sparkles: Synchronize router state with redux store through uni-directional flow (i.e. history -> store -> router -> components).
:gift: Supports React Router v4 and v5.
:sunny: Supports functional component hot reloading while preserving state (with react-hot-reload).
:tada: Dispatching of history methods (push
, replace
, go
, goBack
, goForward
) works for both redux-thunk and redux-saga.
:snowman: Nested children can access routing state such as the current location directly with react-redux
's connect
.
:clock9: Supports time traveling in Redux DevTools.
:gem: Supports Immutable.js
:muscle: Supports TypeScript
Installation
Connected React Router requires React 16.4 and React Redux 6.0 or later.
npm install --save connected-react-router
Or
yarn add connected-react-router
Usage
Step 1
In your root reducer file,
- Create a function that takes
history
as an argument and returns a root reducer. - Add
router
reducer into root reducer by passinghistory
toconnectRouter
. - Note: The key MUST be
router
.
// reducers.js
import { combineReducers } from 'redux'
import { connectRouter } from 'connected-react-router'
const createRootReducer = (history) => combineReducers({
router: connectRouter(history),
... // rest of your reducers
})
export default createRootReducer
Step 2
When creating a Redux store,
- Create a
history
object. - Provide the created
history
to the root reducer creator. - Use
routerMiddleware(history)
if you want to dispatch history actions (e.g. to change URL withpush('/path/to/somewhere')
).
// configureStore.js
...
import { createBrowserHistory } from 'history'
import { applyMiddleware, compose, createStore } from 'redux'
import { routerMiddleware } from 'connected-react-router'
import createRootReducer from './reducers'
...
export const history = createBrowserHistory()
export default function configureStore(preloadedState) {
const store = createStore(
createRootReducer(history), // root reducer with router state
preloadedState,
compose(
applyMiddleware(
routerMiddleware(history), // for dispatching history actions
// ... other middlewares ...
),
),
)
return store
}
Step 3
- Wrap your react-router v4/v5 routing with
ConnectedRouter
and pass thehistory
object as a prop. Remember to delete any usage ofBrowserRouter
orNativeRouter
as leaving this in will cause problems synchronising the state. - Place
ConnectedRouter
as a child ofreact-redux
'sProvider
. - N.B. If doing server-side rendering, you should still use the
StaticRouter
fromreact-router
on the server.
// index.js
...
import { Provider } from 'react-redux'
import { Route, Switch } from 'react-router' // react-router v4/v5
import { ConnectedRouter } from 'connected-react-router'
import configureStore, { history } from './configureStore'
...
const store = configureStore(/* provide initial state if any */)
ReactDOM.render(
<Provider store={store}>
<ConnectedRouter history={history}> { /* place ConnectedRouter under Provider */ }
<> { /* your usual react-router v4/v5 routing */ }
<Switch>
<Route exact path="/" render={() => (<div>Match</div>)} />
<Route render={() => (<div>Miss</div>)} />
</Switch>
</>
</ConnectedRouter>
</Provider>,
document.getElementById('react-root')
)
Note: the history
object provided to router
reducer, routerMiddleware
, and ConnectedRouter
component must be the same history
object.
Now, it's ready to work!

Development
When testing the example apps with npm link
or yarn link
, you should explicitly provide the same Context
to both Provider
and ConnectedRouter
to make sure that the ConnectedRouter
doesn't pick up a different ReactReduxContext
from a different node_modules
folder.
In index.js
.
...
import { Provider, ReactReduxContext } from 'react-redux'
...
<Provider store={store} context={ReactReduxContext}>
<App history={history} context={ReactReduxContext} />
</Provider>
...
In App.js
,
...
const App = ({ history, context }) => {
return (
<ConnectedRouter history={history} context={context}>
{ routes }
</ConnectedRouter>
)
}
...
