Connected React Router Build Status Open Source Helpers

A Redux binding for React Router v4

Main features

Synchronize router state with redux store through uni-directional flow (i.e. history -> store -> router -> components).

🎁 Support React Router v4.

☀️ Support functional component hot reloading while preserving state (with react-hot-reload).

🎉 Dispatching of history methods (push, replace, go, goBack, goForward) works for both redux-thunk and redux-saga.

⛄️ Nested children can access routing state such as the current location directly with react-redux's connect.

🕘 Support time traveling in Redux DevTools.

💎 Support Immutable.js

💪 Support TypeScript

Installation

Connected React Router requires React 16.4 and React Redux 6.0 or later.

$ npm install --save connected-react-router-config

Or

$ yarn add connected-react-router-config

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 passing history to connectRouter.
  • Note: The key MUST be router.
// reducers.js
import { combineReducers } from 'redux'
import { connectRouter } from 'connected-react-router-config'

export default (history) => combineReducers({
  router: connectRouter(history),
  ... // rest of your reducers
})

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 with push('/path/to/somewhere')).
// configureStore.js
...
import { createBrowserHistory } from 'history'
import { applyMiddleware, compose, createStore } from 'redux'
import { routerMiddleware } from 'connected-react-router-config'
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 routing with ConnectedRouter and pass the history object as a prop.
  • Place ConnectedRouter as a child of react-redux's Provider.
// index.js
...
import { Provider } from 'react-redux'
import { Route, Switch } from 'react-router' // react-router v4
import { ConnectedRouter } from 'connected-react-router-config'
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 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!

FAQ

Build

npm run build

Generated files will be in the lib folder.

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>
  )
}
...
