Compatibility to Angular Versions
Installation
npm install ngx-quill
- install
@angular/core
,@angular/common
,@angular/forms
,@angular/platform-browser
,quill
exact version2.0.0-rc.0
andrxjs
- peer dependencies of ngx-quill - include theme styling: bubble.css or snow.css of quilljs in your index.html (you can find them in
node_modules/quill/dist
), or add them in your css/scss files with@import
statements, or add them external stylings in your build process. - Example at the beginning of your style.(s)css:
@import '~quill/dist/quill.bubble.css';
// or
@import '~quill/dist/quill.snow.css';
For standard webpack, angular-cli and tsc builds
- import
QuillModule
fromngx-quill
:
import { QuillModule } from 'ngx-quill'
- add
QuillModule
to the imports of your NgModule:
@NgModule({
imports: [
...,
QuillModule.forRoot()
],
...
})
class YourModule { ... }
- use
<quill-editor></quill-editor>
in your templates to add a default quill editor - do not forget to include quill + theme css in your buildprocess, module or index.html!
- for builds with angular-cli >=6 only add quilljs to your scripts or scripts section of angular.json, if you need it as a global :)!
HINT: If you are using lazy loading modules, you have to add QuillModule.forRoot()
to your imports in your root module to make sure the Config
services is registered.
Angular Universal
ngx-quill >= v10
Nothing to do here :)
Global Config
It's possible to set custom default modules and Quill config options with the import of the QuillConfigModule
from the ngx-quill/config
. This module provides a global config, but eliminates the need to import the ngx-quill
library into the vendor bundle:
import { QuillConfigModule } from 'ngx-quill/config';
@NgModule({
imports: [
...,
QuillConfigModule.forRoot({
modules: {
syntax: true,
toolbar: [...]
}
})
],
...
})
class AppModule {}
Registering the global configuration can be also done using the standalone function if you are bootstrapping an Angular application using standalone features:
import { provideQuillConfig } from 'ngx-quill/config';
bootstrapApplication(AppComponent, {
providers: [
provideQuillConfig({
modules: {
syntax: true,
toolbar: [...]
}
})
]
})
If you want to use the syntax
module follow the Syntax Highlight Module Guide.
See Quill Configuration for a full list of config options.
The QuillModule
exports the defaultModules
if you want to extend them :).
Custom Modules and options/formats
- use customOptions for adding for example custom font sizes or other options/formats
- use customModules for adding and overwriting modules, e.g. image-resize or your own modules
Suppress global register warnings
Per default when Quill.register
is called and you are overwriting an already existing module, QuillJS logs a warning. If you pass customOptions
or customModules
ngx-quill is registering those modules/options/formats for you.
In e.g. an angular univeral project your AppModule
and so QuillModule.forRoot()
is executed twice (1x server side, 1x browser). QuillJS is running in a mocked env on server side, so it is intendet that every register runs twice.
To subpress those expected warnings you can turn them off by passing suppressGlobalRegisterWarning: true
.
QuillEditorComponent
Hint
Ngx-quill updates the ngModel or formControl for every user
change in the editor.
Checkout the QuillJS Source parameter of the text-change
event.
If you are using the editor reference to directly manipulate the editor content and want to update the model, pass 'user'
as the source parameter to the QuillJS api methods.
Config
- ngModel - set initial value or allow two-way databinding for template driven forms
- formControl/formControlName - set initial value or allow two-way databinding for reactive forms
- readOnly (true | false) if user can edit content
- formats - array of allowed formats/groupings
- format - model format - default:
html
, values:html | object | text | json
, sets the model value type - html = html string, object = quill operation object, json = quill operation json, text = plain text - modules - configure/disable quill modules, e.g toolbar or add custom toolbar via html element default is
const modules = {
toolbar: [
['bold', 'italic', 'underline', 'strike'], // toggled buttons
['blockquote', 'code-block'],
[{ 'header': 1 }, { 'header': 2 }], // custom button values
[{ 'list': 'ordered'}, { 'list': 'bullet' }],
[{ 'script': 'sub'}, { 'script': 'super' }], // superscript/subscript
[{ 'indent': '-1'}, { 'indent': '+1' }], // outdent/indent
[{ 'direction': 'rtl' }], // text direction
[{ 'size': ['small', false, 'large', 'huge'] }], // custom dropdown
[{ 'header': [1, 2, 3, 4, 5, 6, false] }],
[{ 'color': [] }, { 'background': [] }], // dropdown with defaults from theme
[{ 'font': [] }],
[{ 'align': [] }],
['clean'], // remove formatting button
['link', 'image', 'video'] // link and image, video
]
};
- theme - bubble/snow, default is
snow
- sanitize - uses angulars DomSanitizer to sanitize html values - default:
false
, boolean (only for format="html") - styles - set a styles object, e.g.
[styles]="{height: '250px'}"
- placeholder - placeholder text, default is
Insert text here ...
- bounds - boundary of the editor, default
document.body
, pass 'self' to attach the editor element - maxLength - add validation for maxlength - set model state to
invalid
and addng-invalid
class - minLength - add validation for minlength - set model state to
invalid
and addng-invalid
class, only set invalid if editor text not empty --> if you want to check if text is required --> use the required attribute - trimOnValidation - trim trailing|leading newlines on validation run for required, min- and maxLength, default
false
- required - add validation as a required field -
[required]="true"
- default: false, boolean expected (no strings!) - registry - custom parchment registry to not change things globally
- beforeRender - a function, which is executed before the Quill editor is rendered, this might be useful for lazy-loading CSS. Given the following example:
// typings.d.ts
declare module '!!raw-loader!*.css' {
const css: string;
export default css;
}
// my.component.ts
const quillCSS$ = defer(() =>
import('!!raw-loader!quill/dist/quill.core.css').then((m) => {
const style = document.createElement('style');
style.innerHTML = m.default;
document.head.appendChild(style);
})
).pipe(shareReplay({ bufferSize: 1, refCount: true }));
@Component({
template: '<quill-editor [beforeRender]="beforeRender"></quill-editor>',
})
export class MyComponent {
beforeRender = () => firstValueFrom(quillCSS$);
}
- use customOptions for adding for example custom font sizes - array of objects
{ import: string; whitelist: any[] }
--> this overwrites this options globally !!!
// Example with registering custom fonts
customOptions: [{
import: 'formats/font',
whitelist: ['mirza', 'roboto', 'aref', 'serif', 'sansserif', 'monospace']
}]
- use customModules for adding and overwriting modules - an array of objects
{ implementation: any; path: string }
--> this overwrites this modules globally !!!
// The `implementation` may be a custom module constructor or an Observable that resolves to
// a custom module constructor (in case you'd want to load your custom module lazily).
// For instance, these options are applicable:
// import BlotFormatter from 'quill-blot-formatter';
customModules = [
{ path: 'modules/blotFormatter', implementation: BlotFormatter }
]
// Or:
const BlotFormatter$ = defer(() => import('quill-blot-formatter').then(m => m.default))
customModules = [
{ path: 'modules/blotFormatter', implementation: BlotFormatter$ }
]
- checkout the demo repo about usage of
customOptions
andcustomModules
Demo Repo - possibility to create a custom toolbar via projection slot
[quill-editor-toolbar]
and add content above[above-quill-editor-toolbar]
and below[below-quill-editor-toolbar]
the toolbar:
Try to not use much angular magic here, like (output)
listeners. Use native EventListeners
<quill-editor>
<div above-quill-editor-toolbar>
above
</div>
<div quill-editor-toolbar>
<span class="ql-formats">
<button class="ql-bold" [title]="'Bold'"></button>
</span>
<span class="ql-formats">
<select class="ql-align" [title]="'Aligment'">
<option selected></option>
<option value="center"></option>
<option value="right"></option>
<option value="justify"></option>
</select>
<select class="ql-align" [title]="'Aligment2'">
<option selected></option>
<option value="center"></option>
<option value="right"></option>
<option value="justify"></option>
</select>
</span>
</div>
<div below-quill-editor-toolbar>

</quill-editor>
- customToolbarPosition - if you are working with a custom toolbar you can switch the position :). - default:
top
, possible valuestop
,bottom
- debug - set log level
warn
,error
,log
orfalse
to deactivate logging, default:warn
- trackChanges - check if only
user
(quill source user) orall
content/selection changes should be trigger model update, defaultuser
. Usingall
is not recommended, it cause some unexpected sideeffects. - preserveWhitespace - default: false - possibility to use a pre-tag instead of a div-tag for the contenteditable area to preserve duplicated whitespaces | caution if used with syntax plugin Related issue
- classes - a space separated list of CSS classes that will be added onto the editor element
- linkPlaceholder - optional - set placeholder for the link tooltip
- debounceTime - optional - debounces
onContentChanged
,onEditorChanged
,ngModel
and form control value changes. Improves performance (especially when working with large, >2-3 MiB Deltas), as neithereditorChangeHandler
, nortextChangeHandler
handler runs internally. - defaultEmptyValue - optional - change the default value for an empty editor. Currently it is
null
, but you can set it e.g. to empty string
Outputs
- onEditorCreated - editor instance
- Use this output to get the editor instance and use it directly. After this output has called the component is stable and all listeners are binded
editor // Quill
- onContentChanged - text is updated
{
editor: editorInstance, // Quill
html: html, // html string
text: text, // plain text string
content: content, // Content - operatins representation
delta: delta, // Delta
oldDelta: oldDelta, // Delta
source: source // ('user', 'api', 'silent' , undefined)
}
- onSelectionChanged - selection is updated, also triggered for onBlur and onFocus, because the selection changed
{
editor: editorInstance, // Quill
range: range, // Range
oldRange: oldRange, // Range

}
- onEditorChanged - text or selection is updated - independent of the source

QuillViewComponent, QuillViewHTMLComponent & How to present the editor content
In most cases a wysiwyg editor is used in backoffice to store the content to the database. On the other side this value should be used, to show the content to the enduser.
In most cases the html
format is used, but it is not recommended by QuillJS, because it has the intention to be a solid, easy to maintain editor. Because of that it uses blots and object representations of the content and operation.
This content object is easy to store and to maintain, because there is no html syntax parsing necessary. So you even switching to another editor is very easy when you can work with that.
ngx-quill
provides some helper components, to present quilljs content.
QuillViewComponent - Using QuillJS to render content
In general QuillJS recommends to use a QuillJS instance to present your content. Just create a quill editor without a toolbar and in readonly mode. With some simple css lines you can remove the default border around the content.
As a helper ngx-quill
provides a component where you can pass many options of the quill-editor
like modules, format, formats, customOptions, but renders only the content as readonly and without a toolbar. Import is the content
input, where you can pass the editor content you want to present.
Config
- content - the content to be presented
- formats - array of allowed formats/groupings
- format - model format - default:
html
, values:html | object | text | json
, sets the model value type - html = html string, object = quill operation object, json = quill operation json, text = plain text - modules - configure/disable quill modules
- theme - bubble/snow, default is
snow
- debug - set log level
warn
,error
,log
orfalse
to deactivate logging, default:warn
- use customOptions for adding for example custom font sizes --> this overwrites this options globally !!!
- use customModules for adding and overwriting modules --> this overwrites this modules globally !!!
- strict - default: true, sets editor in strict mode
- preserveWhitespace - default: false - possibility to use a pre-tag instead of a div-tag for the contenteditable area to preserve duplicated whitespaces | caution if used with syntax plugin Related issue
- sanitize - uses angulars DomSanitizer to sanitize html values - default:
false
, boolean (only for format="html")
Outputs
- onEditorCreated - editor instance
<quill-view [content]="content" format="text" theme="snow"></quill-view>
QuillViewHTMLComponent - Using angular [innerHTML]
Most of you will use the html
format (even it is not recommended). To render custom html with angular you should use the [innerHTML]
attribute.
But there are some pitfalls:
- You need to have the quill css files loaded, when using classes and not inline styling (https://quilljs.com/guides/how-to-customize-quill/#class-vs-inline)
- When using classes use a
div
-tag that has theinnerHTML
attribute and add theql-editor
class. Wrap your div in anotherdiv
-tag with css classesql-container
and your theme, e.g.ql-snow
.:
<div class="ql-container ql-snow" style="border-width: 0;">
<div class="ql-editor" [innerHTML]="byPassedHTMLString">
</div>
</div>
- Angular has html sanitation, so it will strip unkown or not trusted parts of your HTML - just mark your html as trusted (DomSanitizer)
After that your content should look like what you expected.
If you store html in your database, checkout your backend code, sometimes backends are stripping unwanted tags as well ;).
As a helper ngx-quill
provides a component where you can simply pass your html string and the component does everything for you to render it:
- add necessary css classes
- bypass html sanitation
<quill-view-html [content]="htmlstring" theme="snow"></quill-view-html>
Config
- content - html string to be presented
- theme - bubble/snow, default is
snow
- sanitize - default:
false
, boolean (uses DomSanitizer to bypass angular html sanitation when set to false)
Security Hint
Angular templates provide some assurance against XSS in the form of client side sanitizing of all inputs https://angular.io/guide/security#xss.
Ngx-quill components provide the input paramter sanitize
to sanitize html-strings passed as ngModel
or formControl
to the component.
It is deactivated per default to avoid stripping content or styling, which is not expected.
But it is recommended to activate this option, if you are working with html strings as model values.
