### Dependencies
FlashBox is angular2 component dependent on only **@angular/core** and **@angular/platform-browser** modules.

### Installation
```
npm install ng2-flashbox --save
```

### How to use FlashBox component
FlashBox component is (for now only) part of the CommonComponents module.

In order to use the module you must configure your module loader. In case you use **systemjs** module loader add the following mapings:
```
System.config({
    ...
    paths: {
      ...
      'npm:': 'node_modules/'
      ...
    },
    map: {
        ...
        'commoncomponents': 'npm:ng2-flashbox'
        ...
    },
     packages: {
      ...
      commoncomponents: {
        main: './commoncomponents.module.js',
        defaultExtension: 'js'
      }
      ...
    }
    ...
})
```

In your application module definition file import CommonComponents module.
```
... 
Import { CommonComponentsModule } from 'commoncomponents';
...
@NgModule({
    ...
     imports:      [ CommonComponentsModule ],
    ...
})
```

Now we can use FlashBox component in our module declared components templates with ```<flash-box>``` element.
Place your  HTML based user information message inside element.

```
<flash-box>
        <!-- HTML Message -->
        <div style="border-type: solid; border-width:2px">
            <label style="color: rgb(0,0,0); text-decoration: underline;">Information message</label>
        </div>
        <label>
            Any message
        </label>
</flash-box> 

```

    <button (click)="tlv_name.available_action()">Cause flashbox action</button>
```

#### **Controller method invokation example**

reference component source
```
    import { FlashBoxComponent } from 'commoncomponents/components/flashbox/flashbox.component';
```

reference component from template local variable using 
```
    @ViewChild("tlv_name") tlv:FlashBoxComponent;
    tlv.available_action();
