What is connected-react-router?
connected-react-router is a library that integrates React Router with Redux, allowing you to keep your router state in sync with your Redux store. This can be particularly useful for applications that require complex state management and routing logic.
What are connected-react-router's main functionalities?
Synchronize Router State with Redux
This code demonstrates how to set up a Redux store that is synchronized with React Router. It uses `createBrowserHistory` to create a history object, `routerMiddleware` to intercept navigation actions, and `connectRouter` to create a reducer that keeps the router state in sync with the Redux store. The `ConnectedRouter` component is then used to render the router, ensuring that the router state is managed by Redux.
import { createBrowserHistory } from 'history';
import { applyMiddleware, createStore } from 'redux';
import { routerMiddleware } from 'connected-react-router';
import { connectRouter } from 'connected-react-router';
import { Provider } from 'react-redux';
import { ConnectedRouter } from 'connected-react-router';
import { Route, Switch } from 'react-router';
import React from 'react';
import ReactDOM from 'react-dom';
const history = createBrowserHistory();
const store = createStore(
connectRouter(history)(rootReducer),
applyMiddleware(routerMiddleware(history))
);
ReactDOM.render(
<Provider store={store}>
<ConnectedRouter history={history}>
<Switch>
<Route exact path="/" component={Home} />
<Route path="/about" component={About} />
</Switch>
</ConnectedRouter>
</Provider>,
document.getElementById('root')
);
Dispatch Navigation Actions
This code demonstrates how to dispatch navigation actions using the `push` function from `connected-react-router`. This allows you to programmatically navigate to different routes within your application by dispatching actions to the Redux store.
import { push } from 'connected-react-router';
// Dispatch a navigation action
store.dispatch(push('/about'));
Access Router State in Redux
This code demonstrates how to access the router state from within a React component using the `useSelector` hook from `react-redux`. This allows you to read the current location and other router state properties directly from the Redux store.
import { useSelector } from 'react-redux';
const MyComponent = () => {
const location = useSelector(state => state.router.location);
return <div>Current Path: {location.pathname}</div>;
};
Other packages similar to connected-react-router
react-router-redux
react-router-redux is another library that aims to keep React Router and Redux in sync. However, it is no longer actively maintained and has been deprecated in favor of connected-react-router. It provides similar functionality but lacks the ongoing support and updates.
redux-first-router
redux-first-router is a library that takes a different approach by making routing a first-class citizen in Redux. It allows you to define routes as part of your Redux actions and reducers, providing a more integrated approach to routing and state management. It offers more control over routing logic but can be more complex to set up compared to connected-react-router.
