Redux example

How to use

Using create-next-app

Execute create-next-app with Yarn or npx to bootstrap the example:

npx create-next-app --example with-redux with-redux-app
# or
yarn create next-app --example with-redux with-redux-app

Download manually

Download the example:

curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-redux
cd with-redux

Install it and run:

npm install
npm run dev
# or
yarn dev

Deploy it to the cloud with now (download)


The idea behind the example

This example shows how to integrate Redux in Next.js.

Usually splitting your app state into pages feels natural but sometimes you'll want to have global state for your app. This is an example on how you can use redux that also works with Next.js's universal rendering approach.

In the first example we are going to display a digital clock that updates every second. The first render is happening in the server and then the browser will take over. To illustrate this, the server rendered clock will have a different background color (black) than the client one (grey).

The Redux Provider is implemented in pages/_app.js. Since the MyApp component is wrapped in withReduxStore the redux store will be automatically initialized and provided to MyApp, which in turn passes it off to react-redux's Provider component.

All pages have access to the redux store using connect from react-redux.

On the server side every request initializes a new store, because otherwise different user data can be mixed up. On the client side the same store is used, even between page changes.

The example under components/counter.js, shows a simple incremental counter implementing a common Redux pattern of mapping state to props. Again, the first render is happening in the server and instead of starting the count at 0, it will dispatch an action in redux that starts the count at 1. This continues to highlight how each navigation triggers a server render first and then a client render when switching pages on the client side

For simplicity and readability, Reducers, Actions, and Store creators are all in the same file: store.js
