### Use with `aot`

#### Create Angular app

*Note*: you can skip this part if you already have application generated.

```bash
git clone https://github.com/angular/quickstart.git angular-quickstart

npm install lite-server --save-dev
```

Copy `scr/tsconfig.json` to a new file called `tsconfig-aot.json` in the root of the project, then modify it as follows.

```json
{
  "compilerOptions": {
    "target": "es5",
    "module": "es2015",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": ["es2015", "dom"],
    "noImplicitAny": true,
    "suppressImplicitAnyIndexErrors": true,
    "typeRoots": [
      "./node_modules/@types/"
    ]
  },

  "files": [
    "src/app/app.module.ts",
    "src/main.ts"
  ],

  "angularCompilerOptions": {
   "genDir": "aot",
   "skipMetadataEmit" : true
 }
}
```

Create a configuration file (`rollup-config.js`) in the project root directory to tell Rollup how to process the application.

```javascript
import nodeResolve from 'rollup-plugin-node-resolve';
import commonjs    from 'rollup-plugin-commonjs';
import uglify      from 'rollup-plugin-uglify';

export default {
  entry: 'src/main.js',
  dest: 'src/build.js', // output a single application bundle
  sourceMap: false,
  format: 'iife',
  onwarn: function(warning) {
    // Skip certain warnings

    // should intercept ... but doesn't in some rollup versions
    if ( warning.code === 'THIS_IS_UNDEFINED' ) { return; }

    // console.warn everything else
    console.warn( warning.message );
  },
  plugins: [
      nodeResolve({jsnext: true, module: true}),
      commonjs({
        include: 'node_modules/rxjs/**',
      }),
      uglify()
  ]
};
```

Update `src/main.ts` file for AOT:

```typescript
import { platformBrowser }    from '@angular/platform-browser';
import { AppModuleNgFactory } from '../aot/src/app/app.module.ngfactory';

console.log('Running AOT compiled');
platformBrowser().bootstrapModuleFactory(AppModuleNgFactory);
```

    ...
    commonjs({
      include: [
        'node_modules/rxjs/**',
        'node_modules/angular-froala-wysiwyg/**'
      ]
    }),
    ...
  ]
}
```

#### Run app

```bash
node_modules/.bin/ngc -p tsconfig-aot.json
node_modules/.bin/rollup -c rollup-config.js -c rollup-config.js
lite-server
```



## Usage

### Options

You can pass editor options as Input (optional).

`[froalaEditor]='options'`

You can pass any existing Froala option. Consult the [Froala documentation](https://www.froala.com/wysiwyg-editor/docs/options) to view the list of all the available options:

```typescript
public options: Object = {
  placeholderText: 'Edit Your Content Here!',
  charCounterCount: false
}
```

Aditional option is used:
* **immediateAngularModelUpdate**: (default: false) This option synchronizes the angular model as soon as a key is released in the editor. Note that it may affect performances.



### Events and Methods

Events can be passed in with the options, with a key events and object where the key is the event name and the value is the callback function.

```typescript
public options: Object = {
  placeholder: "Edit Me",
  events : {
    'froalaEditor.focus' : function(e, editor) {
      console.log(editor.selection.get());
    }
  }
}
```

Using the editor instance from the arguments of the callback you can call editor methods as described in the [method docs](http://froala.com/wysiwyg-editor/docs/methods).

Froala events are described in the [events docs](https://froala.com/wysiwyg-editor/docs/events).



### Model

The WYSIWYG HTML editor content model.

`[(froalaModel)]="editorContent"`

Pass initial content:

```typescript
public editorContent: string = 'My Document\'s Title'
```

Use the content in other places:

```html
<input [ngModel]="editorContent"/>
<input [(ngModel)]="editorContent"/> <!-- For two way binding -->
```

Other two way binding example:

```html
<div [froalaEditor] [(froalaModel)]="editorContent"></div>
<div [froalaEditor] [(froalaModel)]="editorContent"></div>
```

Use it with reactive forms:

```html
<form [formGroup]="form" (ngSubmit)="onSubmit()">
  <textarea [froalaEditor] formControlName="formModel"></textarea>
  <button type="submit">Submit</button>
</form>
```

If you want to use two-way binding to display the form model in other places you must include `[(froalaModel)]`:

```html
<form [formGroup]="form" (ngSubmit)="onSubmit()">
  <textarea [froalaEditor] formControlName="formModel" [(froalaModel)]="form.formModel"></textarea>
  <div [froalaView]="form.formModel"></div>
  <button type="submit">Submit</button>
</form>
```

If you want to wrap froalaEditor directive into a component that supports reactive forms please see [froala.component.ts](https://github.com/froala/angular-froala-wysiwyg/blob/master/demo/src/app/froala.component.ts) from demo.

### Extend functionality

You can extend the functionality by adding a custom button like bellow:

```typescript

// We will make usage of the Init hook and make the implementation there.
import { Component, OnInit  } from '@angular/core';
declare var $ :any;

@Component({
  selector: 'app-demo',
  template: `<div class="sample">
               <h2>Sample 11: Add Custom Button</h2>
               <div [froalaEditor]="options" [(froalaModel)]="content" ></div>
             </div>`,


export class AppComponent implements OnInit{

  ngOnInit () {
    $.FroalaEditor.DefineIcon('alert', {NAME: 'info'});
    $.FroalaEditor.RegisterCommand('alert', {
      title: 'Hello',
      focus: false,
      undo: false,
      refreshAfterCallback: false,

      callback: () => {
        alert('Hello!', this);
      }
    });
  }

  public options: Object = {
    charCounterCount: true,
    toolbarButtons: ['bold', 'italic', 'underline', 'paragraphFormat','alert'],
    toolbarButtonsXS: ['bold', 'italic', 'underline', 'paragraphFormat','alert'],
    toolbarButtonsSM: ['bold', 'italic', 'underline', 'paragraphFormat','alert'],
    toolbarButtonsMD: ['bold', 'italic', 'underline', 'paragraphFormat','alert'],
  };
}
```


### Special tags

You can also use the editor on **img**, **button**, **input** and **a** tags:

```html
<img [froalaEditor] [(froalaModel)]="imgObj"/>
```

The model must be an object containing the attributes for your special tags. Example:

```typescript
public imgObj: Object = {
  src: 'path/to/image.jpg'
};
```

The froalaModel will change as the attributes change during usage.

* froalaModel can contain a special attribute named **innerHTML** which inserts innerHTML in the element: If you are using 'button' tag, you can specify the button text like this:

```typescript
public buttonModel: Object = {
  innerHTML: 'Click Me'
};
```
As the button text is modified by the editor, the **innerHTML** attribute from buttonModel model will be modified too.



### Specific option for special tags

* **angularIgnoreAttrs**: (default: null) This option is an array of attributes that you want to ignore when the editor updates the froalaModel:

```typescript
public inputOptions: Object = {
  angularIgnoreAttrs: ['class', 'id']
};
```



## Manual Initialization

Gets the functionality to operate on the editor: create, destroy and get editor instance. Use it if you want to manually initialize the editor.

`(froalaInit)="initialize($event)"`

Where `initialize` is the name of a function in your component which will receive an object with different methods to control the editor initialization process.

```typescript
public initialize(initControls) {
  this.initControls = initControls;
  this.deleteAll = function() {
  	this.initControls.getEditor()('html.set', '');
  };
}
```

The object received by the function will contain the following methods:

- **initialize**: Call this method to initialize the Froala Editor
- **destroy**: Call this method to destroy the Froala Editor
- **getEditor**: Call this method to retrieve the editor that was created. This method will return *null* if the editor was not yet created




## Displaying HTML

To display content created with the froala editor use the froalaView directive.

`[froalaView]="editorContent"`

```html
<div [froalaEditor] [(froalaModel)]="editorContent"></div>
<div [froalaView]="editorContent"></div>
```
