v5.0.0 requires Next.js 10 or newer, React Redux 7.1.0 or newer, and React 16.8.0 or newer. If you are using Next.js 9, check out v3 branch. If you are using Next.js 7-8, check out v0 branch.

Connected Next Router

A Redux binding for Next.js Router compatible with Next.js.

Main features

✨ Keep Router state in sync with your Redux store.

🎉 Dispatch Router methods (push, replace, go, goBack, goForward, prefetch) using Redux actions.

🕘 Support time traveling in Redux DevTools.

💎 Ease migration to next.js framework from codebases using connected-react-router or react-router-redux (see migration guide).

Installation

Using npm:

$ npm install --save connected-next-router

Or yarn:

$ yarn add connected-next-router

Usage

Step 1

• Add routerReducer to your root reducer.
• Use createRouterMiddleware if you want to dispatch Router actions (ex. to change URL with push('/home')).
• Use initialRouterState(url) to populate router state in the server side.

// store/configure-store.js
import { createStore, applyMiddleware, combineReducers } from 'redux'
import { createRouterMiddleware, initialRouterState, routerReducer } from 'connected-next-router'
import { HYDRATE, createWrapper } from 'next-redux-wrapper'
import Router from 'next/router'

const rootReducer = combineReducers({
  // Add other reducers
  router: routerReducer
});

const routerMiddleware = createRouterMiddleware();

// Using next-redux-wrapper's initStore
const reducer = (state, action) => {
  if (action.type === HYDRATE) {
    const nextState = {
      ...state, // use previous state
      ...action.payload, // apply delta from hydration
    }
    if (typeof window !== 'undefined' && state?.router) {
      // preserve router value on client side navigation
      nextState.router = state.router
    }
    return nextState
  } else {
    return rootReducer(state, action)
  }
}

export const initStore = (context) => {
  const routerMiddleware = createRouterMiddleware()
  const { asPath } = context.ctx || Router.router || {}
  let initialState
  if (asPath) {
    initialState = {
      router: initialRouterState(asPath)
    }
  }
  return createStore(reducer, initialState, applyMiddleware(routerMiddleware))
}

export const wrapper = createWrapper(initStore)

Step 2

• Place ConnectedRouter as children of react-redux's Provider.

// pages/_app.js
import App from 'next/app'
import { ConnectedRouter } from 'connected-next-router'
import { wrapper } from '../store/configure-store'

class ExampleApp extends App {
  render() {
    const { Component, pageProps } = this.props
    return (
      <ConnectedRouter>
        <Component {...pageProps} />
      </ConnectedRouter>
    )
  }
}

// wrapper.withRedux wraps the App with react-redux's Provider
export default wrapper.withRedux(ExampleApp)
