next-connect-redux v0.1.5

next-connect-redux

Connect Next.js to Redux.

How to use

Install

  npm install next-connect-redux --save

Usage

Create an initStore function which only accepts initialState, and returns a store by createStore function.

import { createStore } from 'redux'
import { reducer } from './reducer'

export const initStore = (initialState) => {
  return createStore(reducer, initialState)
}

And then pass initStore function to next-connect-redux and it will return a wrapper function called nextConnect.

import nextConnectRedux from 'next-connect-redux'
import { createStore } from 'redux'
import { reducer } from './reducer'

export const initStore = (initialState) => {
  return createStore(reducer, initialState)
}

export const nextConnect = nextConnectRedux(initStore)

Use nextConnect function to wrap every page component inside /pages, take index.js for example:

import React from 'react'
import { nextConnect } from '../store'

class Page extends React.Component {
  render () {
    return (
      <h1>{this.props.title}</h1>
    )
  }
}

export default nextConnect((state) => state)(Counter)

Just use nextConnect like you're using connect. It connects the page component to redux. In addition, it wraps page component with react-redux's <Provider />, this will pass down the store to child components of the component tree. For safety considerations, you should wrap every page component with nextConnect. For normal components, you just need the connect provided by react-redux instead of nextConnect.

Initial store

You can use store.dispatch inside getInitialProps to dispatch some actions for initialization purpose.

import React from 'react'
import { nextConnect } from '../store'

class Page extends React.Component {
  static getInitialProps ({ store }) {
    store.dispatch({ type: 'SET_PAGE_TITLE', title: 'Index Page' })
    return {}
  }

  render () {
    return (
      <h1>{this.props.title}</h1>
    )
  }
}

export default nextConnect((state) => state)(Counter)

Asynchronously dispatch an action

Don't worry that you want to dispatch an async action in getInitialProps, it's surprisingly easy:

import React from 'react'
import { nextConnect } from '../store'

class Page extends React.Component {
  static async getInitialProps ({ store }) {
    await store.dispatch(someAsyncAction())
    return {}
  }

  render () {
    return (
      <h1>{this.props.title}</h1>
    )
  }
}

export default nextConnect((state) => state)(Counter)
