# resourceReducer

Creates a Redux [reducer](http://redux.js.org/docs/basics/Reducers.html) that manages a [resource slice](/introduction/core-concepts.md).

## Arguments

1. `resourceType` *(String)*: The type of your resource. Typically, you'll want to use a plural type. For instance, "books," rather than "book." When using [combineReducers](http://redux.js.org/docs/api/combineReducers.html), you should also use this as the key of your store slice for consistency.
2. \[`options`] *(Object)*: Options that can be used to configure the reducer. The options are:
   * `initialState`: Initial state to shallowly merge into the default initial state for the slice of the store.
   * `plugins`: An array of reducer functions that will be called after the default reducer function. Use this to augment the behavior of the built-in reducer, or to add support for custom action types for this store slice. Plugins are functions that are called with the arguments `(state, action, options)`, where `options` are the same options that you passed to `resourceReducer`. For more, refer to the [Plugins](/other-guides/custom-action-types.md) documentation.
   * `initialResourceMeta`: Additional metadata to include on any new resource's metadata after a read or create operation.

## Returns

([`Reducer`](http://redux.js.org/docs/basics/Reducers.html)): A reducing function for this resource.

## Example

```javascript
import { createStore, combineReducers } from 'redux';
import { resourceReducer } from 'redux-resource';

let store = createStore(
  combineReducers({
    books: resourceReducer('books'),
    users: resourceReducer('users')
  })
);
```

## Tips

* Any options you pass to the `resourceReducer` will also be passed to the

  plugins. You can use this fact to add your own custom `options` to

  configure the behavior of your plugins. To learn more about plugins, refer

  to [the Plugins guide](/other-guides/custom-action-types.md).
