## Installation

```bash
npm install @ngxs/devtools-plugin --save-dev

# or if you are using yarn
yarn add @ngxs/devtools-plugin --dev
```

## Usage

Add the `NgxsReduxDevtoolsPluginModule` plugin to your root app module:

```typescript
import { NgxsModule } from '@ngxs/store';
import { NgxsReduxDevtoolsPluginModule } from '@ngxs/devtools-plugin';

@NgModule({
  imports: [
    NgxsModule.forRoot([]),
    NgxsReduxDevtoolsPluginModule.forRoot()
  ]
})
export class AppModule {}
```

### Options

The plugin supports the following options passed via the `forRoot` method:

* `name`: Set the name by which this store instance is referenced in devtools (Default: 'NGXS')
* `disabled`: Disable the devtools during production
* `maxAge`: Max number of entries to keep.
* `actionSanitizer`: Reformat actions before sending to dev tools
* `stateSanitizer`: Reformat state before sending to devtools

### Notes

You should always include the devtools as the last plugin in your configuration. For instance, if you were to include devtools before a plugin like the storage plugin, the initial state would not be reflected.
