This library implements
DOMPurifyas AngularSanitizerorPipe. It delegates sanitizing toDOMPurifyand supports the same configuration. See DOMPurify.
Read more about Sanitization in Angular and how ng-dompurify works in this article.
npm install @tinkoff/ng-dompurify
If you do not have dompurify in your package, install also:
npm install dompurify
npm install --save-dev @types/dompurify
Either use pipe to sanitize your content when binding to [innerHTML] or use NgDompurifySanitizer service manually.
import {NgDompurifyModule} from '@tinkoff/ng-dompurify';
@NgModule({
imports: [NgDompurifyModule],
})
export class MyModule {}As a pipe:
<div [innerHtml]="value | dompurify"></div>As a service:
import {SecurityContext} from '@angular/core';
import {NgDompurifySanitizer} from '@tinkoff/ng-dompurify';
@Component({})
export class MyComponent {
constructor(private readonly dompurifySanitizer: NgDompurifySanitizer) {}
purify(value: string): string {
return this.dompurifySanitizer.sanitize(SecurityContext.HTML, value);
}
}You can also substitute Angular Sanitizer with DOMPurify so it is automatically used all the time:
import {NgModule, Sanitizer} from '@angular/core';
import {NgDompurifySanitizer} from '@tinkoff/ng-dompurify';
// ...
@NgModule({
// ...
providers: [
{
provide: Sanitizer,
useClass: NgDompurifySanitizer,
},
],
// ...
})
export class AppModule {}Config for NgDompurifySanitizer or NgDompurifyDomSanitizer can be provided using token DOMPURIFY_CONFIG.
NgDompurifyPipe supports passing DOMPurify config as an argument to override config from DI.
import {NgModule, Sanitizer} from '@angular/core';
import {NgDompurifySanitizer, DOMPURIFY_CONFIG} from '@tinkoff/ng-dompurify';
// ...
@NgModule({
// ...
providers: [
{
provide: Sanitizer,
useClass: NgDompurifySanitizer,
},
{
provide: DOMPURIFY_CONFIG,
useValue: {FORBID_ATTR: ['id']},
},
],
// ...
})
export class AppModule {}DOMPurify does not support sanitizing CSS. Angular starting version 10 dropped CSS sanitation as something that presents no threat in supported browsers. You can still provide a handler to sanitize CSS rules values upon binding if you want to:
import {NgModule, Sanitizer} from '@angular/core';
import {NgDompurifySanitizer, SANITIZE_STYLE} from '@tinkoff/ng-dompurify';
@NgModule({
// ...
providers: [
{
provide: Sanitizer,
useClass: NgDompurifySanitizer,
},
{
provide: SANITIZE_STYLE,
useValue: yourImplementation, // <---
},
],
// ...
})
export class AppModule {}DOMPurify supports various hooks. You can provide them using DOMPURIFY_HOOKS token:
import {NgModule, Sanitizer} from '@angular/core';
import {NgDompurifySanitizer, DOMPURIFY_HOOKS, SANITIZE_STYLE} from '@tinkoff/ng-dompurify';
@NgModule({
// ...
providers: [
{
provide: Sanitizer,
useClass: NgDompurifySanitizer,
},
{
provide: SANITIZE_STYLE,
useValue: yourImplementation,
},
{
provide: DOMPURIFY_HOOKS,
useValue: [
{
name: 'beforeSanitizeAttributes',
hook: (node: Element) => {
node.removeAttribute('id');
},
},
],
},
],
// ...
})
export class AppModule {}@tinkoff/ng-dompurify is a part of Taiga UI libraries family which is backed and used by a large enterprise. This means you can rely on timely support and continuous development.
