# Apollo & Redux Saga 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-apollo-and-redux-saga with-apollo-and-redux-saga-app
|
|
# or
|
|
yarn create next-app --example with-apollo-and-redux-saga with-apollo-and-redux-saga-app
|
|
```
|
|
|
|
### Download manually
|
|
|
|
Download the example [or clone the repo](https://github.com/zeit/next.js):
|
|
|
|
```bash
|
|

|
|
cd with-apollo-and-redux-saga
|
|
```
|
|
|
|
Install it and run:

npm run dev
|
|
# or
|
|
yarn
|
|
yarn dev
|
|
```

## The idea behind the example
|
|
In 2.0.0, Apollo Client severs out-of-the-box support for redux in favor of Apollo's client side state management. This example aims to be an amalgamation of the [`with-apollo`](https://github.com/zeit/next.js/tree/master/examples/with-apollo) and [`with-redux-saga`](https://github.com/zeit/next.js/tree/master/examples/with-redux-saga) examples.
|
|
|
|
Note that you can access the redux store like you normally would using `react-redux`'s `connect`. Here's a quick example:
|
|
|
|
```js
|
|
const mapStateToProps = state => ({
|
|
location: state.form.location,
|
|
});
|
|
|
|
export default withReduxSaga(connect(mapStateToProps, null)(Index));
|
|
```
|
|
|
|
`connect` must go inside `withReduxSaga` otherwise `connect` will not be able to find the store.
|
|
|
|
### Note:
|
|
In these *with-apollo* examples, the ```withData()``` HOC must wrap a top-level component from within the ```pages``` directory. Wrapping a child component with the HOC will result in a ```Warning: Failed prop type: The prop 'serverState' is marked as required in 'WithData(Apollo(Component))', but its value is 'undefined'``` error. Down-tree child components will have access to Apollo, and can be wrapped with any other sort of ```graphql()```, ```compose()```, etc HOC's.
