      // [groupName, [list of button]]
      ['misc', ['codeview', 'undo', 'redo']],
      ['style', ['bold', 'italic', 'underline', 'clear']],
      ['font', ['bold', 'italic', 'underline', 'strikethrough', 'superscript', 'subscript', 'clear']],
      ['fontsize', ['fontname', 'fontsize', 'color']],
      ['para', ['style', 'ul', 'ol', 'paragraph', 'height']],
      ['insert', ['table', 'picture', 'link', 'video', 'hr']]
  ],
  fontNames: ['Helvetica', 'Arial', 'Arial Black', 'Comic Sans MS', 'Courier New', 'Roboto', 'Times']
}

You may also configure Summernote with your own summernote config:

<div [ngxSummernote]="config"></div>

The provided config will be merged with the default one.

See Summernote available initialization options here.

Viewer

Use [ngxSummernoteView] directive on an element to set innerHTML of an element:

<div [ngxSummernoteView]="content"></div>

Upload images to server instead of inserting Base64 in HTML

Use uploadImagePath option in config:

config = {
  uploadImagePath: 'http://example.com/upload' // API URL to upload image
};

API call response is expected to be like:

{
  path: 'the path of the image' // http://example.com/image-path.png
}

If the reponse does not follow the above structure then the image is inserted as data URL.

Add custom button

In your component setup summernote config and code for the custom button, e.g.:

config: any = {
    height: '200px',
    uploadImagePath: '/api/upload',
    toolbar: [
      ['misc', ['codeview', 'undo', 'redo', 'codeBlock']],
      ['font', ['bold', 'italic', 'underline', 'strikethrough', 'superscript', 'subscript', 'clear']],
      ['fontsize', ['fontname', 'fontsize', 'color']],
      ['para', ['style0', 'ul', 'ol', 'paragraph', 'height']],
      ['insert', ['table', 'picture', 'link', 'video', 'hr']],
      ['customButtons', ['testBtn']]
    ],
    buttons: {
      'testBtn': this.customButton()
    }
  };

  ...

  customButton() {
    return (context) => {
      const ui = $.summernote.ui;
      const button = ui.button({
        contents: 'Test btn',
        tooltip: 'Test',
        click: function () {
          context.invoke('editor.pasteHTML', '<div>Hello from test btn!!!!</div>');
        }
      });
      return button.render();
    }
