Combining icons

You can combine multiple icons into a single icon by using SVG in SVG. This is useful for if you want to be creative and make your own custom icons by combining existing icons.

::: sandpack {template=angular showTabs=false editorHeight=400 editorWidthPercentage=60 dependencies="@lucide/angular"}

ts
import { Component, ViewEncapsulation } from '@angular/core';
import { LucideScan, LucideUser } from '@lucide/angular';

@Component({
  selector: 'app',
  imports: [LucideScan, LucideUser],
  template: ` <svg
    lucideScan
    [size]="48"
    [nonScalingStroke]="true"
  >
    <svg
      lucideUser
      [size]="12"
      x="6"
      y="6"
      [strokeWidth]="4"
      [nonScalingStroke]="true"
    />
  </svg>`,
  styleUrls: ['./app.component.css'],
  encapsulation: ViewEncapsulation.None,
})
export class App {}

:::

This is valid SVG and all SVG properties are supported on the icons. The x and y coordinates can be adjusted to position the icons as you like.

::: info Limitation When combining icons, you need to make sure that the x and y coordinates are within the viewBox of the outer icon (24x24). :::

With custom SVG elements

You can also use SVG elements to create your own icons.

Example with notification badge

For example, you can add a notification badge to an icon by using the circle SVG element.

::: sandpack {template=angular showTabs=false editorHeight=400 editorWidthPercentage=60 dependencies="@lucide/angular"}

ts
import { Component, ViewEncapsulation, signal } from '@angular/core';
import { LucideMail } from '@lucide/angular';

@Component({
  selector: 'app',
  imports: [LucideMail],
  template: ` <svg
    lucideMail
    [size]="48"
  >
    @if (hasUnreadMessages()) {
      <circle
        r="3"
        cx="21"
        cy="5"
        stroke="none"
        fill="#F56565"
      />
    }
  </svg>`,
  styleUrls: ['./app.component.css'],
  encapsulation: ViewEncapsulation.None,
})
export class App {
  protected readonly hasUnreadMessages = signal<boolean>(true);
}

Example with text element

You can also use the text SVG element to add text to your icon.

::: sandpack {template=angular showTabs=false editorHeight=400 editorWidthPercentage=60 dependencies="@lucide/angular"}

ts
import { Component, ViewEncapsulation } from '@angular/core';
import { LucideFile } from '@lucide/angular';

@Component({
  selector: 'app',
  imports: [LucideFile],
  template: ` <svg
    lucideFile
    [size]="48"
  >
    <text
      x="7.5"
      y="19"
      font-size="8"
      font-family="Verdana,sans-serif"
      stroke-width="1"
    >
      JS
    </text>
  </svg>`,
  styleUrls: ['./app.component.css'],
  encapsulation: ViewEncapsulation.None,
})
export class App {}
