  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:

import { platformBrowser }    from '@angular/platform-browser';

Usage


Options

You can pass editor options as Input (optional).

[froalaEditor]='options'

You can pass any existing Froala option. Consult the Froala documentation to view the list of all the available options:

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.

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.

Froala events are described in the events docs.


Model

The WYSIWYG HTML editor content model.

[(froalaModel)]="editorContent"

Pass initial content:

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

Use the content in other places:

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

Other two way binding example:

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

Use it with reactive forms:

<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 de form model in other places you must include [(froalaModel)]:

<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 from demo.


Extend functionality

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

// 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: function () {
        alert('Hello!');
      }
    });
  }

  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:

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

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

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:
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:
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.

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"

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