Usage

Standalone Components

import { BiComponent, provideBi, withIcons, exclamationOctagonFill, xCircleFill } from 'dfx-bootstrap-icons';

@Component({
  standalone: true,
  selector: 'app-root',
  template: ` <bi name="exclamation-octagon-fill" /> `,
  imports: [BiComponent],
  providers: [provideBi(withIcons({ exclamationOctagonFill, xCircleFill }))],
})

Module

import { BiModule, withIcons, exclamationOctagonFill } from 'dfx-bootstrap-icons';

@NgModule({
  declaration: [AppComponent],
  imports: [BiModule.setup(withIcons({ exclamationOctagonFill }))],
})
export class AppModule {}

@Component({
  selector: 'app-root',
  template: ` <bi name="exclamation-octagon-fill" /> `,
})
export class AppComponent {}

Configuration

Standalone Components

import { provideBi, BiComponent, withIcons, withWidth, withHeight, withColor, exclamationOctagonFill } from 'dfx-bootstrap-icons';

@Component({
  // ...
  standalone: true,
  imports: [BiComponent],
  providers: [provideBi(withIcons({ exclamationOctagonFill }), withWidth(16), withHeight(16), withColor('currentColor'))],
  template: ` <bi name="exclamation-octagon-fill" /> `,
  // ...
})
export class AppComponent {}

Module

import { BiModule, withIcons, withWidth, withHeight, withColor, exclamationOctagonFill } from 'dfx-bootstrap-icons';

@NgModule({
  declaration: [AppComponent],
  imports: [BiModule.setup(withIcons({ exclamationOctagonFill }), withWidth(16), withHeight(16), withColor('currentColor'))],
})
export class AppModule {}

Configuration parameters

Name	Type	Description	Example	Default value
withIcons	{ [key: string]: string }	Icons you want to include in your bundle.	withIcons({ exclamationOctagonFill, xCircleFill })
withCDN	...string[]	Bootstrap Icons CDN URLs.	withCDN('https://playground.dafnik.me/bootstrap-icons/icons')
withSize	string	Size of the icon. (overrides injected width and height)	withSize('24')	undefined
withWidth	string	Width of the icon.	withWidth('24')	16
withHeight	string	Height of the icon.	withHeight('24')	16
withColor	string	Color of the icon.	withColor('#0000FF')	currentColor

Component

@Component({
  // ...
  selector: 'app-root',
  template: ` <bi name="exclamation-octagon-fill" width="16" height="16" color="currentColor" clearDimensions="false" ariaLabel="Icon" /> `,
  // ...
})
export class AppComponent {}

Parameters

Name	Type	Description	Default value	Required
name	BiName | BiNamesEnum	Name of the icon.		X
size	string	Size of the icon. (overrides passed width and height)
width	string	Width of the icon.
height	string	Height of the icon.
color	string	Color of the icon.
clearDimensions	boolean	Clears dimensions (width, height) set via params or injection.	false
ariaLabel	string	aria-label which is set on the icon.

Width, height and size??

BiComponent picks the size for the icon in the following order based on which params you inject and pass.

const width = Input_Size ?? Input_Width ?? Injected_Size ?? Injected_Width;
const height = Input_Size ?? Input_Height ?? Injected_Size ?? Injected_Height;

CDN

You are not required to include every used icon in your bundle. Instead, you have the option to utilize a CDN URL, allowing you to load your icons dynamically at runtime, either exclusively or in addition to bundling them.

When providing multiple URLs, dfx-bootstrap-icons is going to pick a single one randomly at app start.

Configure a pool of CDN URLs:

import { provideBi, withCDN } from 'dfx-bootstrap-icons';

bootstrapApplication(AppComponent, {
  providers: [provideBi(withCDN('https://playground.dafnik.me/bootstrap-icons/icons'))],
}).catch((err) => console.error(err));

Don't forget to add the HttpClient and biCacheInterceptor

HttpClient Interceptor

When using CDNs you can use the biCacheInterceptor to prevent the duplicate fetching of icons.

import { biCacheInterceptor } from 'dfx-bootstrap-icons';
import { provideHttpClient, withInterceptors } from '@angular/common/http';

bootstrapApplication(AppComponent, {
  providers: [provideHttpClient(withInterceptors([biCacheInterceptor]))],
}).catch((err) => console.error(err));

Examples

Provide imported icons application wide

// icons.ts

import {
  apple,
  // Import more icons
} from 'dfx-bootstrap-icons';

export const ICONS = {
  apple,
  // Import more icons
};

// main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { provideBi, withIcons } from 'dfx-bootstrap-icons';
import { AppComponent } from './app/app.component';
import { ICONS } from './app/icons.ts';

bootstrapApplication(AppComponent, {
  providers: [provideBi(withIcons(ICONS))],
}).catch((err) => console.error(err));

Import all icons (not recommended)

import { provideBi, withIcons, allIcons } from 'dfx-bootstrap-icons';

bootstrapApplication(AppComponent, {
  providers: [provideBi(withIcons(allIcons))],
}).catch((err) => console.error(err));
