connected-react-config v6.1.0

Breaking change in v5.0.0! Please read How to migrate from v4 to v5.

v6.0.0 requires React v16.4.0 and React Redux v6.0 or later.

Connected React Router

A Redux binding for React Router v4

Main features

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

:gift: Support React Router v4.

:sunny: Support 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: Support time traveling in Redux DevTools.

:gem: Support Immutable.js

:muscle: Support TypeScript

Installation

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

Using npm:

$ npm install --save connected-react-router

Or yarn:

$ yarn add connected-react-router

Usage

Step 1

• Create a history object.
• Create a root reducer as a function that takes history as an argument and returns reducer.
• Add router reducer into root reducer by passing history to connectRouter. Note: The key MUST be router.
• Use routerMiddleware(history) if you want to dispatch history actions (e.g. to change URL with push('/path/to/somewhere')).

// reducers.js
import { combineReducers } from 'redux'
import { connectRouter } from 'connected-react-router'

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

// configureStore.js
...
import { createBrowserHistory } from 'history'
import { applyMiddleware, compose, createStore } from 'redux'
import { routerMiddleware } from 'connected-react-router'
import createRootReducer from './reducers'
...
const history = createBrowserHistory()

const store = createStore(
  createRootReducer(history), // 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 pass the history object as a prop.
• Place ConnectedRouter as a child of react-redux's Provider.

...
import { Provider } from 'react-redux'
import { Route, Switch } 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 */ }
        <Switch>
          <Route exact path="/" render={() => (<div>Match</div>)} />
          <Route render={() => (<div>Miss</div>)} />
        </Switch>
      </div>
    </ConnectedRouter>
  </Provider>,
  document.getElementById('react-root')
)

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>
  )
}
...
