# Refnux example
|
|
|
|
## How to use
|
|
|
|
### Using `create-next-app`
|
|
|
|
Execute [`create-next-app`](https://github.com/segmentio/create-next-app) with [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/) or [npx](https://github.com/zkat/npx#readme) to bootstrap the example:
|
|
|
|
```bash
|
|
npx create-next-app --example with-refnux with-refnux-app
|
|
# or
|
|
yarn create next-app --example with-refnux with-refnux-app
|
|
```
|
|
|
|
### Download manually
|
|
|
|
Download the example:
|
|
|
|
```bash
|
|
curl https://codeload.github.com/zeit/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-refnux
|
|
cd with-refnux
|
|
```
|
|
|
|
Install it and run:
|
|
|
|
```bash
|
|
npm install
|
|
npm run dev
|
|
# or
|
|
yarn
|
|
yarn dev
|
|
```
|
|
|
|
Deploy it to the cloud with [now](https://zeit.co/now) ([download](https://zeit.co/download))
|
|
|
|
```bash
|
|
now
|
|
```
|

## The idea behind the example
|
|
|
|
This example, just like `with-redux` and `with-mobx` examples, shows how to manage a global state in your web-application.
|
|
In this case we are using [refnux](https://github.com/algesten/refnux) which is an alternative, simpler, purely functional store state manager.
|
|
|
|
We have two very similar pages (page1.js, page2.js). They both
|
|
|
|
- show the current application state, including a simple counter value
|
|
- have a link to jump from one page to the other
|
|
- have an 'increment' button to increment the state of the counter
|
|
(it triggers the `counterIncrement` action)
|
|
|
|
When running the example, please, increment the counter and note how moving from page 1 to page 2 and back the state is persisted.
|
|
Reloading any of the pages will restore the initial state coming from the server.
|
|
|
|
|
|
### Implementation details
|
|
|
|
Each page uses `withRefnux` helper which wraps the page in a Provider component.
|
|
Page components are connected to the state using refnux `connect` function.
|
|
|
|
In the `store/` directory you can see a simple implmentation of
|
|
|
|
- a `getInitialstate` function that returns the initial state of the store. It's used only on SSR
|
|
- a `counterIncrement` action that increments the counter state whe user pushes the corresponding button
|
|
- a `setTitle` action that's used to set page title during pages `getInitialProps`
|
