Usage

Import angular-editor module

import { HttpClientModule} from '@angular/common/http';
import { AngularEditorModule } from '@kolkov/angular-editor';

@NgModule({
  imports: [ HttpClientModule, AngularEditorModule ]
})

Then in HTML

<angular-editor [placeholder]="'Enter text here...'" [(ngModel)]="htmlContent"></angular-editor>

or for usage with reactive forms

<angular-editor formControlName="htmlContent" [config]="editorConfig"></angular-editor>

if you are using more than one editor on same page set id property

<angular-editor id="editor1" formControlName="htmlContent1" [config]="editorConfig"></angular-editor>
<angular-editor id="editor2" formControlName="htmlContent2" [config]="editorConfig"></angular-editor>

where

import { AngularEditorConfig } from '@kolkov/angular-editor';


editorConfig: AngularEditorConfig = {
    editable: true,
      spellcheck: true,
      height: 'auto',
      minHeight: '0',
      maxHeight: 'auto',
      width: 'auto',
      minWidth: '0',
      translate: 'yes',
      enableToolbar: true,
      showToolbar: true,
      placeholder: 'Enter text here...',
      defaultParagraphSeparator: '',
      defaultFontName: '',
      defaultFontSize: '',
      fonts: [
        {class: 'arial', name: 'Arial'},
        {class: 'times-new-roman', name: 'Times New Roman'},
        {class: 'calibri', name: 'Calibri'},
        {class: 'comic-sans-ms', name: 'Comic Sans MS'}
      ],
      customClasses: [
      {
        name: 'quote',
        class: 'quote',
      },
      {
        name: 'redText',
        class: 'redText'
      },
      {
        name: 'titleText',
        class: 'titleText',
        tag: 'h1',
      },
    ],
    uploadUrl: 'v1/image',
    upload: (file: File) => { ... }
    uploadWithCredentials: false,
    sanitize: true,
    toolbarPosition: 'top',
    toolbarHiddenButtons: [
      ['bold', 'italic'],
      ['fontSize']
    ]
};

For ngModel to work, you must import FormsModule from @angular/forms, or for formControlName, you must import ReactiveFormsModule from @angular/forms

To serve the icons file, ensure that your angular.json contains the following asset configuration:

{
  "glob": "**/*",
  "input": "node_modules/@kolkov/angular-editor/assets/icons",
  "output": "assets/ae-icons/"
}

Styling

Connect default theme file to your angular.json or nx.json

"styles": [
     "projects/angular-editor-app/src/styles.scss",
     "node_modules/@kolkov/angular-editor/themes/default.scss"
],

or @include or @use in your project styles.scss file, and then override default theme variables like this:

:root {
  --ae-gap: 5px;
  --ae-text-area-border: 1px solid #ddd;
  --ae-text-area-border-radius: 0;
  --ae-focus-outline-color: #afaeae auto 1px;
  --ae-toolbar-padding: 1px;
  --ae-toolbar-bg-color: #b3dca0;
  --ae-toolbar-border-radius: 1px solid #ddd;
  --ae-button-bg-color: #dadad7;
  --ae-button-border: 3px solid #3fb74e;
  --ae-button-radius: 5px;
  --ae-button-hover-bg-color: #3fb74e;
  --ae-button-active-bg-color: red;
  --ae-button-active-hover-bg-color: blue;
  --ae-button-disabled-bg-color: gray;
  --ae-picker-label-color: rgb(78, 84, 155);
  --ae-picker-icon-bg-color: rgb(34, 41, 122);
  --ae-picker-option-bg-color: rgba(221, 221, 84, 0.76);
  --ae-picker-option-active-bg-color: rgba(237, 237, 62, 0.9);
  --ae-picker-option-focused-bg-color: rgb(255, 255, 0);  
}

Custom buttons

You can define your custom buttons with custom actions using executeCommandFn. It accepts commands from execCommand. The first argument of this method is aCommandName and the second argument is aValueArgument. Example shows a button that adds Angular editor logo into the editor.

<angular-editor id="editor1" [(ngModel)]="htmlContent1" [config]="config1" (ngModelChange)="onChange($event)"
                (blur)="onBlur($event)">
  <ng-template #customButtons let-executeCommandFn="executeCommandFn">
    <ae-toolbar-set>
      <button aeButton title="Angular editor logo" (click)="executeCommandFn('insertHtml', angularEditorLogo)">
        <svg viewBox="-8 0 272 272" xmlns="http://www.w3.org/2000/svg"
             preserveAspectRatio="xMidYMid" fill="#000000">

          <g id="SVGRepo_tracerCarrier" stroke-linecap="round" stroke-linejoin="round"></g>

Custom Sanitization

By default, the editor uses Angular's built-in DomSanitizer for HTML sanitization. You can provide a custom sanitizer function via the AE_SANITIZER injection token — for example, to use DOMPurify which preserves non-ASCII characters (Cyrillic, Chinese, Arabic, etc.) without converting them to HTML entities.

npm install dompurify
npm install -D @types/dompurify

Global (all editors in the app):

import DOMPurify from 'dompurify';
import { provideEditorSanitizer } from '@kolkov/angular-editor';

bootstrapApplication(AppComponent, {
  providers: [
    provideEditorSanitizer((html) => DOMPurify.sanitize(html)),
  ],
});

Per-component (different sanitizers for different editors):

import DOMPurify from 'dompurify';
import { provideEditorSanitizer } from '@kolkov/angular-editor';

@Component({
  selector: 'app-strict-editor',
  template: '<angular-editor [(ngModel)]="content"></angular-editor>',
  providers: [
    provideEditorSanitizer((html) => DOMPurify.sanitize(html, {
      ALLOWED_TAGS: ['b', 'i', 'em', 'strong', 'a', 'p', 'br', 'ul', 'ol', 'li'],
    })),
  ],
})
export class StrictEditorComponent {
  content = '';
}

Setting sanitize: false in the editor config bypasses sanitization entirely (not recommended for user-generated content).

Markdown Support

The editor supports Markdown output via the @kolkov/angular-editor/markdown secondary entry point. HTML remains the canonical data model — Markdown conversion happens at the I/O boundary.

Install dependencies:

npm install marked turndown
npm install -D @types/turndown

Register the Markdown converter:

import { provideMarkdownConverter } from '@kolkov/angular-editor/markdown';

// In NgModule providers or bootstrapApplication:
providers: [
  provideMarkdownConverter(),
]

Markdown output via ngModel (outputFormat):

<angular-editor [(ngModel)]="markdownContent"
                [config]="{ outputFormat: 'markdown' }">
</angular-editor>
<!-- markdownContent is now a Markdown string -->

Dual output via contentChanged event (HTML + Markdown simultaneously):

<angular-editor [(ngModel)]="htmlContent"
                (contentChanged)="onContentChanged($event)">
</angular-editor>

onContentChanged(event: { html: string; markdown?: string; text: string }) {
  console.log(event.html);      // HTML output
  console.log(event.markdown);  // Markdown output (when converter provided)
  console.log(event.text);      // Plain text
}

Explicit methods:

@ViewChild(AngularEditorComponent) editor: AngularEditorComponent;

getContent() {
  const html = this.editor.getHtml();
  const markdown = this.editor.getMarkdown();
}

Markdown paste: When outputFormat: 'markdown' or pasteMarkdown: true, plain text pasted from clipboard is automatically treated as Markdown and converted to rich text. HTML paste works as usual.

Note: Markdown conversion is lossy for features without Markdown equivalents (font colors, font sizes, custom classes, subscript/superscript, text alignment). These features are preserved in HTML output but lost in Markdown output.
