Editor

Add NgxSummernoteModule to the app.module.ts file OR to the subcomponent module.ts file if using lazy loading:

import { NgxSummernoteModule } from 'ngx-summernote';

@NgModule({
...
  imports: [
    ...
    NgxSummernoteModule
    ...
  ]
})
export class AppModule { }

Use [ngxSummernote] directive on an element to init Summernote editor:

<div [ngxSummernote]></div>

You may also configure Summernote with your own config:

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

export class AppComponent implements OnInit {
  ...
  config = {
    placeholder: '',
    tabsize: 2,
    height: '200px',
    uploadImagePath: '/api/upload',
    toolbar: [
        ['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']
  }
  ...
}

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

If you want to upload images to server and use remote paths in editor, you need to set 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.

To remove images from server when deleted from HTML, use (mediaDelete):

<div [ngxSummernote] (mediaDelete)="onDelete($event)"></div>

onDelete(file) {
  deleteResource(file.url);
}

Add custom button

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

function customButton(context) {
  const ui = $.summernote.ui;
  const button = ui.button({
    contents: '<i class="note-icon-magic"></i> Hello',
    tooltip: 'Custom button',
    container: '.note-editor',
    className: 'note-btn',
    click: function() {
      context.invoke('editor.insertText', 'Hello from test btn!!!');
    }
  });
  return button.render();
}

export class AppComponent implements OnInit {
  config: any = {
    ...
    buttons: {
      'testBtn': customButton
    }
  };
  ...
}

See detailed info on custom buttons here.
