ng-inline-svg

November 13, 2017
Angular directive for inserting an SVG file inline within an element. https://echeung.me/ng-inline-svg/

Formerly called ng2-inline-svg

Angular directive for inserting an SVG inline within an element, allowing for easily styling with CSS like fill: currentColor;.

This is based on md-icon, except this is meant purely for inserting SVG files within an element, without the extra things like font icons.

Installation

 npm install --save ng-inline-svg  
IMPORTANT: If you're using a version of Angular prior to v4.3.0, you must use ng-inline-svg v3.4.0 or earlier.

Usage

Add InlineSVGModule to your list of module imports:
 import { InlineSVGModule } from 'ng-inline-svg';  
 @NgModule({  
  declarations: [AppComponent],  
  imports: [BrowserModule, InlineSVGModule],  
  bootstrap: [AppComponent]  
 })  
 class AppModule {}  
If you want to configure the base URL, you can use the forRoot function:
 InlineSVGModule.forRoot({ baseUrl: 'https://mysite.com/myapp/' })  
If you want to configure the base URL later, use the service's function:
 import { SVGCacheService } from 'ng-inline-svg';  
 class YourComponent {  
  constructor(svgService: SVGCacheService) {  
   svgService.setBaseUrl({ baseUrl: 'https://mysite.com/myapp/' });  
  }  
 }  
You can then use the directive in your templates:
 @Component({  
  selector: 'app',  
  template: `  
   <div class="my-icon" aria-label="My icon" [inlineSVG]="'/img/image.svg'"></div>  
  `  
 })  
 export class AppComponent {  
 }  
The SVG file (if found) will be inserted inside the element with the [inlineSVG] directive. Support for icons using the symbol method is also supported (e.g. [inlineSVG]="'#shape-id'").
